Description

[Detailed explanation of the invention] Conventional fertilizing rice transplanters cover the fertilizing drive device such as a pump with a cover to prevent muddy soil from being thrown up by the planting rod. There were disadvantages such as the marks on the hanging cover becoming invisible and making it difficult to shift gears.Also, the pump and gearbox were located far from the wheels, which caused the aircraft to be unbalanced. To improve this, it was necessary to attach a balance weight to the front of the machine, and the piping connecting the fertilizer tank, pump, and fertilizer rod became long, increasing material and installation costs, and causing blockages.

The purpose of the present invention is to improve the above-mentioned drawbacks, and in a fertilizing rice transplanter in which a planting device is attached to the rear of the machine body equipped with a fertilizing device, a portion near the front wheels of the planting device is provided. A fertilizer tank is provided on the machine body, a frame plate perpendicular to the machine traveling direction is fixed to the machine body below the fertilizer tank, and a transmission device and a fertilization drive device are installed on the side of the frame plate opposite to the planting device. It is characterized by the fact that

The embodiments shown in the drawings will be explained below.
1 is a machine body equipped with an engine 2 at the front, a planting device 3 at the rear, and a float 4 at the bottom, and on both sides there is a swing transmission case with wheels 5, 5 mounted on the rear. 6 and 6 are mounted so as to be able to swing up and down by an output shaft.

Reference numeral 7 denotes a frame plate having an inverted L shape when viewed from the front, which is provided on the body 1 near the wheels 5, and as shown in FIG. is welded to one side of the mounting band 8,
8 can be adjusted to move back and forth by tightening the upper and lower parts with screws 9a, 9a, and a pump A consisting of a plurality of pressure chambers is installed as a fertilization drive device on the upper front side of the frame plate 7, and a pump A is installed on the side. A transmission device B is installed in which a belt 11 is releasably stretched around upper and lower multi-stage pulleys 10, 10, and is housed in a casing 12.

The suction port of each pressure chamber of the pump A is connected to a hose 13.
The fertilizer tank 9 is connected to the fertilizer tank 9 supported above the machine body 1, and the plurality of discharge ports are attached to the float 4 and extend downward from each planting rod 14 of the planting device 1. , the detector 16...
It is communicated by a conduit 17 having...

The main bonnet 18 has a recess at the rear into which the fertilizer tank 9 is inserted, and extends from the engine 2 to the rear of the wheels 5. The main bonnet 18 is connected to the front end of the recess and the pillars 19 erected on both sides of the rear. Auxiliary seedling stands 21, 21 protruding to both sides are installed on the sub-bonnet 20 constructed between them, and the supports 19, 1
A gate-shaped support frame 22 is attached to the upper end of the detector 9, and the tops of the detectors 16 are screwed onto the support frame 22.

The fertilizer tank 9 has a residual gauge 23a, a breather pipe 23b, and an inlet lid 24, and has a main bonnet 18 and a sub-bonnet 20 at the front.
and screws 20a, and the rear part is the main bonnet 1.
8, the front end high part and rear end low part of the recessed part of the main bonnet 18 are connected in a bracing manner by the fertilizer tank 9 and the stay 25. , the auxiliary seedling stand 2 on the top
1, 21 is reinforced,
The rear surface of the detector 16 is covered by three horizontal reference rods 26 (upper and lower), and a grip portion 27 of a recoil starter for starting the engine 2 can be attached to and detached from a plate protruding from one of the rods 19. It is locked in.

Further, the main bonnet 18 has a fulcrum shaft 29 at the rear thereof on the upper part of a stay 28 which is erected on the fuselage 1.
Since it is supported by the fulcrum shaft 29, it can be opened and closed about the fulcrum shaft 29, and the engine 2, pump A, transmission B, etc. can be easily maintained and inspected.

The pump A is driven by the output shaft of a transmission B via a chain 30, and the input shaft of the transmission B is a transmission shaft 32 which is telescopic and whose both ends are connected to the front and rear shafts by universal joints 31, 31. Transmission case 3
It is driven by a shaft 40 rotating in a chain 39 in the fuselage 1 via shafts 34, 35 in the fuselage 3, bevel gears 36, 36, a chain 37, and an input shaft 38.

In the above-mentioned fertilizing rice transplanter, when each actuating part is driven to move the machine forward, the planting rods 14... each scrape out one seedling in the seedling stand 41 and plant it on the rice field, and the pump A The paste-like fertilizer in the fertilizer tank 9 is sucked in and forced out into each conduit 17, and the forced out fertilizer passes through each detector 16 and enters the muddy soil near the planted seedlings from each fertilizer application pipe 15... is fertilized.

If this kind of fertilization and planting work continues, the conduit 17
...Paste fertilizer may adhere to the inside of the pipe 17.
The fertilizer discharge from some of the fertilizing pipes 15 may deteriorate due to bending of the fertilizing pipes 15.

In such a case, the liquid level of the paste fertilizer in the detector 16 leading to the fertilization pipe 15 rises, and the operator detects this visually using the reference rod 26 as a guide.
Eliminate the cause of the blockage.

Furthermore, when the fertilizer tank 9 is empty, the liquid level in the detector 16 becomes low, so when this is discovered in the same manner as described above, the work is interrupted and paste fertilizer is replenished.

Furthermore, the planting rod 14 and the wheels 5, 5 throw up mud during work, but the pump A and the transmission B are attached to the front of the frame plate 7, so that the planting rod 14 side and the wheels 5 are lifted up and rotated. Since it is covered by the frame plate 7, it is possible to prevent mud from adhering to and accumulating on the pump A and the transmission B. Furthermore, since the pump A and transmission B are mounted on the machine body 1 near the wheels, the whole machine body 1 has a good longitudinal balance, and it is possible to omit the provision of balance weights at the front of the machine body as in the conventional case. By moving and adjusting the frame plate 7 back and forth, the front-rear balance of the aircraft body 1 can be adjusted to an appropriate state.

In addition, since both pump A and transmission B have longitudinal shafts and are mounted from the top to the sides of the machine body 1, they only slightly protrude outward from the transmission body 1 from the base. Without this, the left and right balance of the machine body 1 is also good and stable planting work can be performed.

Furthermore, the pump A has a fertilizer tank 9 and a fertilizer pipe 1.
5, and directly below the fertilizer tank 9.
Since it is on top, piping is simple and easy.

As mentioned above, the present invention is a fertilizing rice transplanter with a planting device attached to the rear of the machine body equipped with a fertilizing device.
A fertilizer tank is provided on the machine body near the front wheels of the planting device, a frame plate perpendicular to the direction of movement of the machine body is fixed to the machine body below the fertilizer tank, and a frame plate is fixed to the machine body at the bottom of the fertilizer tank, and a frame plate is provided on the side opposite to the planting device of the frame plate. Since the transmission and the fertilization drive device are installed, the frame plate can catch the mud thrown up by the wheels and planting rods, preventing the mud from accumulating on the fertilization drive and the transmission. It can be easily done without removing mud.

In addition, since the fertilizing drive device and transmission device are attached to the machine body near the wheels, the entire fertilizing rice transplanter has good front-to-back balance, making it possible to easily carry out fertilizing and planting work without a balance weight. .

Moreover, the fertilizer tank, the fertilizer application drive device, and the fertilizer application rod can be placed close to each other, and piping can be simplified.
