Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a pulverizing and mixing machine suitable for use in pulverizing seedlings and mixing them with fertilizer.

(Conventional technology) Conventionally, the work of crushing the top of the seedlings used for raising seedlings was
- carried out using the crusher disclosed in Publication No. 39550,
The pulverized soil and fertilizer are mixed in a mixer and used again as seedling seedlings.

(Problems to be solved by the invention) Because the soil was crushed and the fertilizer was mixed separately, the work efficiency for raising seedlings and preparing bed soil was poor, and it was difficult to carry the machine into and out of the passenger house. It was difficult to do so, and it was difficult to reduce the moisture level of the soil, especially when pulverizing the soil or mixing fertilizer, resulting in poor performance in raising seedlings.

(Means for Solving the Problems) The present invention is capable of crushing soil and mixing it with fertilizer at the same time, and in particular, is capable of accelerating the drying of soil using wind power generated by high-speed rotation. A soil charging hopper and a fertilizer charging hopper are provided in the upper part near the end, and the other end of the conveyor is faced from one side inside the sieve-shaped rotating cylinder.
The free ends of chain members that are in the same phase in the circumferential direction of chain members whose base ends are attached at equal intervals in the circumferential direction and whose axial opening and closing are separated by parallel mounting shafts in a hopper-shaped housing are connected to form a crushing rod. A pulverizing and mixing device characterized in that a striking mixing mechanism consisting of a left-handed rotary body and a right-handed rotary body that are fixed and rotatable inwardly from each other is disposed within the sieve-shaped rotating cylinder and below the other end of the conveyor. It is.

(Function) The present invention mixes soil and fertilizer transferred on a conveyor by the respective crushing rods and chain members of the left-hand rotary body and the right-hand rotary body that rotate inwardly at high speed in the hammer-mixing mechanism, The drying of the soil can be accelerated by the wind force generated by the left-handed and right-handed rotating bodies that rotate at high speed.

(Example) Embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the pulverizing and mixing device 1 is provided with an inclined conveyor 3 in a machine frame 2, and an earth charging top 4 and an I11! !
A charging hopper 5 is also provided.

A sieve-shaped rotating cylinder 6 is provided near the right end of the machine frame 2, and the sieve-shaped rotating cylinder 6 is inclined with lIIllwA downward to the right. I'm coming.

The sieve-like rotating cylinder 6 has annular frames 7, 7 on both sides connected by a plurality of connecting rods 8, 8..., and has a large number of small holes 9,
A mesh metal perforated plate 10 having 9... is stretched, a chain 11 is wound and fixed around the periphery of one annular frame 7, and fixed to the top of a vertical rod 12 whose lower part is fixed to the machine frame 2. A chain wheel 15 and a pulley 16 are fixed to a rotating shaft 14 supported by a bearing 13 provided therein, the chain wheel 15 is engaged with the chain wheel 11, and a pulley (not shown) is fixed to a drive shaft 18 rotated by a motor 17. ) and the belt 1 to the pulley 16.
9 ii) is installed to operate the motor 17 and drive shaft 1.
8. The tA wheel 15 is rotated together with the rotating shaft 14 via the belt 19 and the pulley 16, and the sieve-shaped rotating cylinder 6 is rotated via the chino 11.

Next, a striking and mixing mechanism 20 is disposed in the lower part of the sieve-like rotating cylinder 6.

As shown in FIGS. 1, 2, and 3, the crushing and mixing chamber structure 20 has a hopper-like housing 21 that is open at the top and bottom and has a front wall 21a, a rear wall 21b, and side walls 210, 210. From one side opening 6a to the other side opening 6b of the sieve-shaped rotating cylinder 6
Mounting shafts 22°2 extending horizontally toward and parallel to each other.
As shown in FIG. 3, mounting cylinders 24 are fixed to these mounting shafts 22 and 23, and the mounting cylinders 24 are spaced apart from each other in the axial direction of the mounting shafts 22 and 23, and at equal intervals in the circumferential direction.
4 are provided with chain members 25, 25... with their respective proximal ends attached, and the free ends of the chain members 25, 25 that are in the same phase in the circumferential direction of these chain members 25, 25... are connected to form a cross section. In this way, the crushing rod 26 is fixed and the mounting shaft 22 is fixed.
A left rotating body 27 is formed which has a crushing rod 26 which connects the free ends of a pair of chain members 25 and 25 in the axial direction in the same phase in the circumferential direction through the mounting cylinder 24, and is connected to the mounting shaft 23 through the mounting cylinder 24. A right-handed rotary body 28 is formed which has a crushing rod 26 in which the free ends of a pair of chain members 25 in the axial direction are connected in the same phase in the circumferential direction.

As shown in FIG. 2, the left rotating body 27 and the right rotating body 28 are formed so that the mounting shafts 22 and 23 are rotated inwardly at high speed through a transmission mechanism 29.

Therefore, due to the rotation of the mounting shafts 22, 23, the left rotating body 27 and the right rotating body 28 rotate inwardly, and due to the centrifugal force, they become radial, and the crushing rods 26, 26... extend straight,
It becomes radial and the crushing rods 26, 26... are swung around.

In this case, the left rotating body 27 and the right rotating body 28 during rotation
The crushing rods 26, 26 are selected to avoid collision and to provide the desired distance of approach.

The machine frame 2 is equipped with wheels 30 so that it can be moved freely, and a plurality of rods 31, 31, etc. are installed at the charging inlet of the soil charging hopper 4 between the side walls to remove large lumps of soil. It is to be charged after breaking it.

In the figure, 32 is a rotation guide member for the sieve-shaped rotating cylinder 6, 33 is a discharge guide plate, and 34 is a conveyor driving motor.

Since the present invention is configured as described above, the motor 17.34
is activated, the conveyor 3 is run, the sieve-shaped rotating cylinder 6 is rotated, and the striking and mixing mechanism 20 is activated.
The soil charged in the soil charging hopper 4 is dropped onto the conveyor 3, and the fertilizer is dropped onto the soil on the conveyor 3 with a slight delay from the fertilizer charging hopper 5, and then finally falls from the other end 3b of the conveyor 3. The soil and fertilizer are finely crushed and mixed by a bell mixing mechanism 20.

That is, a left-handed rotating body 27 that rotates at high speed, and a striking bell rod 2 that is a right-handed rotating body.
8 striking bell rod 26.26... and chain member 25.25
The soil and fertilizer that fall are crushed and mixed, and drying is accelerated by the wind force generated by the left-hand rotating body 27 and the right-handed rotating body 28, which rotate at high speed.

While being mixed in this manner, they fall from the lower opening of the hopper-like housing 21 to the lower part of the rotating sieve-like rotary cylinder 6.

The mixture of soil and fertilizer that has fallen to the lower part of the sieve-like rotary cylinder 6 is sieved, falls onto the inclined discharge guide plate 33, and is discharged.

(Effects of the Invention) The present invention crushes soil and fertilizer transferred on a conveyor using a hammering rod and a chain member that are rotated at high speed by the n-speed rotation of the left-handed rotating body and the right-handed rotating body of the striking mixing mechanism. The soil is finely crushed and mixed well, and the wind force generated by the high-speed rotation of the left-handed and right-handed rotating bodies can dry the soil and reduce its moisture content.
