Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fertilizer supply port structure in a fertilizer application machine such as a fertilizer application machine, a fertilizer sowing machine, and a fertilizer rice transplanter.

[Problems to be Solved by Prior Art and Invention] Generally, in this type of fertilizer applicator, fertilizer is applied as the machine runs. In this case, it is necessary to fill the fertilizer tank with fertilizer, but if there is more than one fertilizer tank at this time, it is possible to use a common supply port so that one fertilizer tank can simultaneously supply multiple fertilizer tanks. It is also desirable from the standpoint of improving workability.

However, in this way, since it is necessary to supply a large amount of fertilizer at once at this time, it is necessary to increase the size of the supply port, and then in the case of using the conventional screw-type cap system that attaches and detaches the supply port. However, there is a problem in that the cap cannot be capped even with a slight misalignment, and an extremely careful cap mounting and dismounting operation is required, which is troublesome and complicated.
Therefore, it is proposed to adopt the open / close lid method instead of the screw method, but in this case, it is necessary to make it easy to open and close the lid and to prevent deformation and damage of the supply port for a long period of time. There is.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised with the object of providing a fertilizer supply port structure in a fertilizer applicator capable of eliminating these drawbacks. A supply port member for supplying fertilizer to the tank is provided so as to be swingable so as to open and close the fertilizer supply port from the supply port main body in which the fertilizer supply port is opened and the front side edge of the supply port of the supply port main body. When the lid and the feed port opening position of the lid are slightly bulged outwardly, the lid and the fertilizer feed port are expanded so as to block between the left and right edges of the fertilizer feeding port, and when the feed port is closed, the feeding port is bulged outward. A cover lid that covers the lid body to a mounting frame that supports the supply port body so as to mount the supply port member on the machine body side while integrally forming a rubber elastic body with a foldable body that is bent and folded. Oscillates freely, and the mounting frame A stopper mechanism is provided between the cover and the cover lid to restrict the swing of the cover lid so as to prevent the lid body in the open posture from further opening and to position and support the cover at the open position.

According to the present invention, the open / close lid system is adopted, and the lid is easily opened / closed so that the fertilizer does not scatter when the supply port is closed.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.
In the drawings, reference numeral 1 denotes a traveling machine body of a riding type fertilizer rice transplanter, and a rear part of the traveling machine body 1 is equipped with a seedling planting section 2 which can be vertically moved up and down.

Further, one end of a withdrawal pipe 5 is communicatively connected to the bottom of one fertilizer tank 3 (the one on the left side in the embodiment). Fertilizer nozzle 9 arranged corresponding to each planting claw 8 of seedling planting section 2 through branch pipe 7 having
The soil is fertilized from here.

A communication port 3a is formed on the inner surfaces of the front upper portions of the fertilizer tank 3 which face each other, and a bellows-shaped interchange portion 10a is formed in the communication port 3a.
The outer end of the communication pipe (10) in which is formed is fitted and sealed and fixed by a stop band (11).

On the other hand, 12 is a supply port assembly, and the supply port assembly 12 is attached to a mounting frame 13. The mounting frame 13 is formed with a substantially-shaped mounting stay 13a for integrally mounting to the machine body frame 1a. The lower end portion of the first stay 13b, which is inclined toward the upper end and whose front end portion is curved upward, is integrally fixed. The lower ends of both arm portions of the second stay 13c having a substantially U shape are integrally fixed to the tip of the first stay 13b, but the second stay 13c is inclined rearward and upward toward the upper portion. . Further, both ends of the third stay 13d curved rearward are integrally fixed between the stays 13b and 13c, and the stays 13b, 13c and 13d will be described later. A mounting frame (13) for mounting the mouth member (14) in a surrounding state is constituted.

Reference numeral 15 is a cover lid that also serves as a bumper.
Is an operating hole for opening and closing by inserting your hand in the center 15
Although a is opened, a support shaft plate 15c is integrally fixed to the left and right side plates 15b of the cover lid 15 by a fixture 15d.
A pin hole 15e is formed in the support shaft plate 15c.
Is fitted and attached to the pin shaft 13e protruding from the tip of the first stay 13b, whereby the cover lid is attached.
The pin 15 has a structure capable of swinging back and forth with the pin shaft 13e as a fulcrum. Further, plate members 15f are provided on the left and right sides of the cover lid 15, and pins 15g are penetratingly attached to the tip end of the connecting plate 15f. Then, with the cover lid 15 closed, the upper ends of the pins 15g are integrally provided on the upper ends of the left and right third stays 13d of the mounting frame 13 via the mounting brackets 13g, respectively. It is configured to be retained in a closed posture by being removably fixed to a stop member 13f composed of a pair of biased locking rollers. Further, when the cover lid 15 is swung forward to be in the open posture, the tip end portion of the support shaft plate 15c does not come into contact with the stopper 13h provided on the first stay 13b and swing further open. Is set. Incidentally, 15j is a protective cover fixed to the peripheral portion of the operation hole 15a.

On the other hand, the supply port member 14 is integrally molded using a flexible rubber elastic material.
14 has a substantially rectangular shape that is long in the left-right direction, and has a supply port F that is opened in a slanted manner so that the lower edge is located in the front, and a supply port that has cylindrical communication port parts 14b formed on both left and right side surfaces. Body 14a
Of the four peripheral edges of the supply port F of the supply port main body 14a, the lid 14c projects from the front side edge (lower side edge) and the folds 14d project from the left and right side edges. However, the left and right side edges of the lid body 14c and the front side edge of the fold body 14d are integrally connected. Then, the supply port member 14 is assembled in a region where the main body 14a is framed by the stays 13b, 13c, 13d of the mounting frame 13 so that the side from which the lid 14c projects is the lower edge of the supply port, Then, by inserting the left and right arm portions and the straddling portion of the second stay 13c into the groove portions 14e formed on the back surfaces of the left and right side edges and the upper side edge, and adhering, the three edges excluding the lower end edge where the lid body 14c is extended. The parts are integrally fixed and made rigid.

Further, plate-shaped supporting portions 15h and 15i are formed on the cover lid 15, and these supporting portions 15h and 15i are fitted into the groove 14f formed on the outer surface of the peripheral portion of the lid body 14c and attached. The lid 14c is integrally fixed, whereby the portion of the lid 14c corresponding to the portion rigidified by the second stay 13c is made rigid. When the cover lid 15 is opened, the supply port F is greatly opened with the lid body 14c and the fold body 14d surrounding the front and left and right sides, and fertilizer can be supplied, but when the cover lid 15 is closed, the lid is closed. The inner peripheral surface of the body 14c, which is made substantially flat (planar), is made rigid by the supporting portions 15h, 15i, and the side edge is made rigid by the second stay 13c of the main body 14a. It is constructed such that it abuts against the part and is hermetically sealed.

Further, with respect to the fold body 14d, in a state where the lid body 14c is naturally opened (that is, the supply port member 14 is in a natural state),
It is curved so as to bulge slightly to the outside on the left and right. Then, as described above, the supply port member 14 is set to be in this natural state in the state where the cover lid 15 is locked and held in the open posture by the stopper 13h, whereby the lid body 14c is set. When the cover lid 15 is closed by the closing operation, the fold body 14d inevitably bulges outward and bends, and when the supply port F is closed, the fold body 14d folds inward and the lid body 14c.
It is taken into consideration that it is not sandwiched between and the peripheral portion of the supply port F. Moreover, on the upper edge of the fold body 14d, a collar piece 14g is formed inward on the body side half part,
When the supply port F is closed, the collar piece 14g covers the open upper part of the fold body 14d which is bulged and deformed to prevent the fertilizer from being scattered and lost.

Further, the tongue pieces 14h and 14i are provided on the upper opening edge of the supply port body 14a.
On the left and right sides of the opening, tongues 14j are respectively projected so as to face the inside of the opening.
Is in a direction against the flow of fertilizer that tends to overflow from the supply port F when closing the lid 14c (the direction in which fertilizer tends to flow forward and leftward and rightward due to the closing operation of the lid 14c). It protrudes diagonally upward, and this tongue piece
14h, 14i, 14j are lids when the lid 14c is closed.
14c is pressed and deformed flexibly, and the supply port main body 14a and the lid 14
It is configured to elastically seal and seal the contact portion with c.

Further, at the upper opening edge of the supply port main body 14a, further scattering prevention pieces 14k, 14n are provided so as to project in an inclined manner toward the front upper side.The scattering prevention pieces 14k, 14n are used when closing the lid 14c. To
It is configured to stop the fertilizer overflowing from the supply port F from scattering to the rear side of the bonnet 1b.

Furthermore, the prevention of active fertilizer scattering from the folds 14d is measured by the lower end of the pin 15g. That is pin 15g
The lower end of the part constitutes the pressing member of the present invention,
As shown in FIG. 22A, this is in the vicinity of the outer side of the fold body 14d that is continuous with the lid body 14c in the opened state of the lid body 14c, and further behind the closed surface (inner surface) of the lid body 14c. It is arranged at a position projecting (on the closing direction side).

When the cover lid 15 is closed, as described above, the fold body 14d tries to bend while gradually bulging outward, but at this time, the fold body 14d in which the pin 15g bulges.
It contacts the outer surface of the front side part that is connected to the lid body 14c (see FIG. 22A), whereby the fold body 14d bulges outward from the part where the pin 15g abuts and the front side part thereof. With the deformation limited, the rear part gradually bulges outward and deforms (see FIG. 22B). From this state, the lid 14
When c is closed, the part (inner bent part) X which is in contact with the pin 15g of the fold body 14d bends with the lid 14c side opening and biting into the inside of the rear part, while outside of this. From the part near the pin 15g in the rear part that bulges in the opposite direction, conversely
It folds in a state where the side 4c is closed (see FIGS. 22C to 22E) to form an outer bent portion Y. As a result, the fold body 14d is deformed into a double-folded state in which the middle portion has the inner fold portion X and the outer fold portion Y, and the front and rear width of the fold body 14d when the lid body 14c is closed. As it becomes smaller, the space surrounded by the folds 14d is set to be smaller than that swelled and deformed in the natural state, and limits the fertilizer inflow amount in the folds 14d when the lid 14c is closed. It is configured to do.

Moreover, in this case, the pin 15g has the lid 14c with the supply port main body.
Position a little before touching 14a and blocking the supply port (22nd
(See FIG. D), the side of the inner bent portion X where the pin 15g abuts is connected to the supply port body 14a of the fold body 14d by moving forward beyond the edge of the supply port. When the fertilizer swells when the front and rear ends of the fold body 14d are closed and the movement of the fertilizer is maximized immediately before the lid body 14c is closed. It is configured to prevent the flow into the deformed fold body 14d.

Further, in this structure, a support arm 1c having an upper end integrally fixed to the front lower end portion of the bonnet 1b is provided outside the foldable and deformable fold body 14d. The lower end of the support arm 1c is swingably supported on the body frame 1a side via a support shaft 1d, and the bonnet 1b is configured to swing open / close about the support shaft 1d as an axis. However, this support arm 1c is in contact with the side of the fold body 14d that is bulged and deformed outward to the side where it is connected to the supply port body 14a, outside the pin 15g,
The folds 14d that bulge and deform will interfere so as to be sandwiched between the pin 15g and the folds 14d, thereby restricting the folds 14d from bulging and deforming outward in the natural state, By bending the pin 15g around the pin 15g so that the region to be bulged and deformed is left on the open side, the space surrounded by the fold body 14d to be bulged and deformed is reduced as much as possible. It is set to close both sides at an early stage.

In the figure, reference numeral 16 denotes a strainer net installed in the supply port main body 14a, but the strainer 16 has a cap portion 16a at the periphery thereof locked to a mesh mounting lip 14m formed in the supply port main body 14a. It is configured to be detachably attached. Also
Reference numeral 17 is a reinforcing ring for reinforcing the fitting portion between the communication port portion 14b of the supply port body 14a and the inner end portion of the communication pipe 10.

In the embodiment of the present invention configured as described above, in order to supply the fertilizer to the fertilizer tank 3, the cover lid 15 may be pulled toward the front to open the supply port F, and the fertilizer supplied from the supply port F may be supplied. Are supplied to the left and right fertilizer tanks 3.
Then, after supplying the required amount of fertilizer, the cover lid 15 may be closed.

In this way, the fertilizer supply to the pair of left and right fertilizer tanks 3,
The feed port F is enclosed by the lid 14c and the fold body 14d on the front side and the left and right sides in a funnel shape. Therefore, the fertilizer is supplied to the lower edge of the feed port F. It will not overflow even if it is supplied in large quantities beyond.

By the way, in order for the lid 14c to be in the open posture, the cover lid 15
The support shaft plate 15c on the side is engaged with the stopper 13h on the mounting frame 13 side, and the cover lid 15 is restricted so as not to swing toward the opening side, and is positioned and supported in this posture. 14c is set in an almost natural opening posture without the fold body 14d being forced to be in an open posture. Therefore, even if the lid 14c is forcibly operated in the opening direction, or if a heavy object such as a bag or a bucket containing fertilizer is placed on the lid 14c, its weight does not work on the lid 14c. The engagement and holding of the support shaft plate 15c by the stopper 13h acts on the mounting frame 13 as a stopper mechanism, and thus the lid 14c can be protected. Moreover, this also regulates the problem that the folds 14d that are extended outward in a curved shape are forcibly pulled, and the folds are also kept.
There is an advantage that the protection of 14d can be measured together.

[Effects] In summary, since the present invention is configured as described above, when the lid of the fertilizer supply port is in the open posture, the fertilizer supply port is expanded with the lid. It prevents the fertilizer from overflowing due to the funnel shape.However, when the lid is closed, the folds always bulge outward and deform,
It is not pinched between the fertilizer supply port and the lid, so that the lid is reliably closed.

Moreover, the cover lid that covers the lid body is positioned and supported by the stopper mechanism formed between it and the mounting frame so as not to swing in the opening direction any more in the opening posture. As a result, even if the lid is forcibly operated in the opening direction or a bag containing fertilizer is placed, its weight is supported by the mounting frame side via the stopper mechanism. Since it does not work on the lid body, therefore, the lid body as well as the extended fold body will not be stretched due to unreasonable force, and will be formed of a rubber elastic body. The supply port member can be reliably protected and the reliability can be improved.
