[0002]

2. Description of the Related Art As a spraying device in a conventional compost spreader, there are a spraying device shown in FIG. 1, a spraying device shown in FIG. 2 and a spraying device shown in FIG.

The spraying device A having the configuration shown in FIG. 1 is of a type generally called a horizontal beater. This spraying device
A luggage frame 1 formed in a box shape and provided on the vehicle body, and the luggage frame 1
A floor conveyor 2 installed on the floor surface of the cargo frame 1 so as to transfer the compost thrown into the rear part, and a beater 3 installed on the rear upper part of the floor conveyor 2 so as to rotate by a horizontal shaft 30. The compost transferred from the floor conveyor 2 is rotated by the blades 31 provided on the beater 3 so as to project from the peripheral surface of the horizontal shaft 30 in the radial direction. It is designed to be sprayed backwards.

The spraying device A having the configuration shown in FIG. 2 is of a type generally called a disk beater. The spraying device of this embodiment is similar to that of the embodiment shown in FIG. 1 in that the beater 3 which is rotated by the horizontal shaft 30 is provided on the upper rear portion of the floor conveyor 2 provided on the floor surface of the packing frame 1. However, the opening on the rear side of the cargo frame 1 encloses the rear portion of the beater 3 with the partition wall 1a, and below the beater 3, there is provided a spraying beater 4 which is rotated by a vertical rotation shaft 40, so that the horizontal The compost crushed by the beater 3 rotated by the shaft 30 is dropped onto the spraying beater 4, and the compost is sprayed by the rotation of the spraying beater 4.

A spraying device A having a configuration shown in FIG. 3 is of a type generally called a vertical beater. The spraying device A of this form does not have the beater 3 for crushing as in the form shown in FIG. 2 described above, but the vertical shaft 50 that rises from the lower part of the packing frame 1 to the upper part of the packing frame 1 behind the floor conveyor 2. By providing the spraying beater 5 which is rotated by the blades 51 ...
It is configured to apply compost.

[0006]

However, in the spreading device A in such a conventional compost spreading machine,
Since the compost supply to the spraying beaters 3, 4, and 5 is directly transferred from the floor conveyor 2, the following problems occur.

A change in the transfer amount of the floor conveyor 2 causes a change in the supply of the compost to the spraying beaters 3, 4, and 5, and as a result, the spray amount changes. Generally, in the case of the ratchet intermittent feed mechanism that is widely used as the speed change mechanism of the floor conveyor 2 of the compost spreader, the movement of the floor conveyor 2 is also intermittent, so that the spreader beaters 3, 4, and 5 are moved. The compost supply also becomes discontinuous, and as a result, the amount of application per hour varies, which causes uneven distribution of the applied compost. When compost is loaded in the packing frame 1 of the compost spreader, if it is not loaded uniformly, the amount of compost on the floor conveyor 2 varies depending on the location, and that is the beater 3 for spreading of the spreader A as it is.
By being transferred to 4.5, uneven distribution of the compost will be generated. Compost with a low specific gravity collapses immediately before being supplied to the spraying beaters of the spraying device A due to vibration of the machine body and the like, and then collapses from the end of the floor conveyor 2 onto the spraying beaters 3, 4, and 5 at a time. As a result, uneven distribution occurs in the sprayed state.

The present invention has been made in order to solve the problems that have occurred in the conventional means as described above, and the compost transferred by the floor conveyor 2 is formed just behind the floor conveyor 2. It is accumulated in the space to be stored, and this is provided on the bottom wall of the space surrounding the lower part of the stirring rotor while stirring so that the compost is not clogged by the stirring rotor arranged in the space. Therefore, it is an object of the present invention to provide a new means for controlling the amount of the compost and feeding it to a spraying beater so that the sprayed compost can be uniformly sprayed without causing uneven distribution.

[0009]

In the present invention, as a means for achieving the above-mentioned object, a floor conveyor which is formed in a box shape with an open upper surface side and a rear surface side and post-feeds compost to the floor surface. On the rear end side of the luggage frame 1 equipped with 2
The shutter gate G provided at the opening on the rear end side and the intermediate plate P provided at the rear of the rear end of the floor conveyer 2
A chamber W surrounded by the rear ends of the left and right machine walls is formed, and a stirring rotor R that stirs and crushes the compost that is fed into the chamber W by the floor conveyor 2 and accumulates therein. Is provided between the front edge of the lower edge of the shutter gate G and the rear edge of the intermediate plate P, and a delivery port Y for discharging the compost in the chamber W downward is provided, and a vertical rotation is provided below it. Axis 4
The present invention provides a spraying device in a compost spreader, which is equipped with a spreader beater 4 that rotates by 0.

[0010]

When the composting device A in the compost spreader according to the present invention constructed as described above is loaded with compost in the cargo frame 1, the compost is deposited on the upper surface of the floor conveyor 2 stretched over the floor of the cargo frame 1. Then, it is sequentially transferred backward by the conveying operation of the floor conveyor 2, and when it comes out from the rear end of the floor conveyor 2, the shutter gate G, the intermediate plate P, and the left and right of the cargo frame 1 are provided at the rear end of the cargo frame 1. The compost accumulated in the chamber W formed by the rear end portions of the machine walls 11 of 11 is arranged so as to rotate in the chamber W in the direction opposite to the drive shaft 20 of the floor conveyor 2. It is constantly stirred and crushed by the stirring rotor R provided, and is held so as not to solidify.

The compost accumulated in the chamber W is a chamber W formed by a lower edge portion 60 that curves toward the front of the shutter gate G and an intermediate plate P disposed in front of the lower edge portion 60. Is supported on the bottom wall of the stirring rotor R
While the fluid is rotated by, the slit-shaped delivery port Y extending in the left-right direction in plan view is formed between the front edge of the lower edge portion 60 of the shutter gate G and the rear edge of the intermediate plate P. It is discharged downward with a constant outflow amount and is dropped onto a spraying beater 4 which is arranged below the chamber W so as to rotate by a vertical rotation shaft 40, and the rotation of the spraying beater 4 is reduced. It is sprayed by.

At this time, the opening of the feeding port Y is moved to the front and back by removing the fixing lever 82 of the spraying amount adjusting rod 80 from the locking groove 810 of the locking member 81 and moving the locking member 81 to another locking position. By refitting into the groove 810, the connecting link 86 connected to the upper end of the shutter gate G rotates about the horizontal support shaft 61 provided in the rear end of the luggage frame 1 and the shutter is released. The gate G is moved back and forth in the horizontal support shaft 61, and the distance between the front edge of the lower edge portion 60 and the rear edge of the intermediate plate P is expanded or contracted, so that the feeding port Y formed by the distance is formed. The degree of opening changes due to the expansion and contraction, whereby the amount of sprayed compost from the outlet Y is changed.

When the force for pushing the shutter gate G rearward becomes larger than the set force of the gate pressure adjusting spring 84 linked to the spray amount adjusting rod 80, the shutter gate G resists the pressure of the spring 84, The opening of the delivery port Y is automatically expanded by rotating backward about the horizontal support shaft 61. The compost fed from the feeding port Y is vigorously discharged and dispersed backward by the blade 41 of the spraying beater 4 which is installed at the lower part of the feeding port Y and rotates on the vertical axis. . The compost remaining on the intermediate plate P at the end of the work can be sent to the spraying beater 4 by rotating the intermediate plate P downward to increase the inclination angle.

The gate G has its upper edge supported on a horizontal support shaft 61 provided at the rear end of the luggage frame 1 so as to be bridged in the left-right direction. Further, an intermediate plate P is installed in front of the front edge of the lower edge of the shutter gate G and behind the rear end of the floor conveyor 2 described above. A room W surrounded by the rear ends of the machine walls on the left and right of the luggage frame 1, the shutter gate G, and the intermediate plate P is formed at the rear portion of the floor conveyor 2 at the rear end of the luggage frame 1. The intermediate plate P may be divided into a plurality of sheets and arranged in parallel in the front and rear.

In the chamber W, an agitating rotor R, which is driven and rotated in the opposite direction of the drive shaft 20 by a rotary shaft 70 in the left-right direction which is parallel to the drive shaft 20 of the floor conveyor 2, is pivotally supported. I am doing it.

In the stirring rotor R, substantially triangular support plates 71 ... Are fixed in parallel to the above-described rotary shaft 70 that is bridged between the left and right machine walls of the load frame 1 at appropriate intervals in the axial direction. The plates 72 having a length substantially corresponding to the left and right widths of the luggage frame 1 are provided at the respective corners of the supporting plates 71.
Compost that is installed in parallel with the bridge, and has projections 73 ... Planted on the outer surfaces of the plates 72 ... Compost that accumulates on the floor conveyor 2 that is loaded into the packing frame 1. But,
The compost fed by the floor conveyor 2 and fed backward from the rear end of the floor conveyor 2 and accumulated in the chamber W is crushed and stirred by the projections 73 on the peripheral surface of the stirring rotor R while being crushed. So that it doesn't harden.

Between the front edge of the lower edge portion 60 of the shutter gate G and the rear edge of the intermediate plate P, as shown in FIG. 5, the compost accumulated in the chamber W is fed downward. A delivery port Y is formed, and the compost is delivered from the delivery port Y to the upper surface of the spraying beater 4 arranged below the delivery port Y so as to rotate by the vertical rotation shaft 40.

The feeding port Y is largely opened from the closed state by rotating the shutter gate G back and forth around the horizontal support shaft 61 by the operation of the spraying amount adjusting rod 80 linked to the shutter gate G. Scale between states.

Further, in a state where the fixing lever 82 is engaged with the locking groove 810 of the locking member 81 and the opening degree of the feeding port Y is fixed, the compost accumulated in the chamber W causes the shutter gate G to move. When the pressure applied to the inner surface increases, the spread amount adjusting rod 80 is pushed into the sliding cylinder 83 while compressing and contracting the spring 84, thereby increasing the opening degree of the delivery port Y.

The intermediate plate P has its rear end side pivotally supported by the fulcrum shaft a, and can be adjusted to a desired inclination angle by an angle adjusting means not shown in the drawing. When the spraying operation is nearing the end, it is lowered forward as shown by the chain line in Fig. 5 while keeping it in a posture of projecting upward as shown by the solid line in Fig. 5. The posture is switched to the ON position, and the remaining compost is dropped onto the upper surface of the spraying beater 4.

The spreader beater 4 has blades 4 radially protruding from a boss portion by driving a rotary shaft 40 in the vertical direction.

Driving the drive shaft 20 of the floor conveyor 2 via the intermittent feed mechanism 9 is the same as in the above-described embodiment, but above the rear end of the floor conveyor 2 is the floor conveyor 2. Depth (height) of compost sent by
A sensor S for detecting the movement of the floor conveyor 2 is arranged so that the position of the regulation plate 90 of the intermittent feeding mechanism 9 is displaced by the detection operation of the sensor S so that the feed amount of the floor conveyor 2 corresponds to the amount of compost transferred by the floor conveyor 2. This is an example in which it is changed.

The regulation plate 90 of the intermittent feeding mechanism 9 and the operation of detecting the height of the compost piled up by the sensor S may be connected by any suitable means such as electrical or mechanical means. The sensor S is formed on a plate that is pivotally supported by a fulcrum shaft a in the left-right direction so as to freely swing up and down along the front-rear direction, and the lower edge contacts the upper surface of the compost sent by the floor conveyor 2. Accordingly, the waiting height of the compost is detected by the amount of rotation of the sensor plate S by rotating backward and upward as shown by the chain line in FIG. The sensor plate S is provided with an arm b that rotates integrally with the plate S about the fulcrum shaft a, and the arm b is connected to the intermittent feed mechanism 9 via the connecting links 12, 13, 14.

Thus, the effective operating range of the ratchet pawl 92 that reciprocates together with the reciprocating arm 91 is set to zero, and the ratchet gear 95 provided on the drive shaft 20 of the floor conveyor 2 is not driven. It becomes zero, the floor feeding stops, and the amount of compost to be post-fed by the floor conveyor 2 decreases, so that the sensor plate S does not come into contact with the compost, as shown by the solid line in FIG. When it hangs vertically, the regulation plate 90 pivots in the direction of pulling the control portion 900 of the regulation plate 90 away from the operating range of the ratchet pawl 92, and the ratchet pawl 9 moves. Expanding the effective operating range of the maximum, the feed amount of the floor conveyor 2 are set to be the maximum.

Then, by this, the floor conveyor 2 feeds it into the chamber W formed at the rear end side of the cargo frame 1,
The amount of accumulated compost is maintained at a substantially constant amount.
