Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a compost spreader used for loading accumulated compost and spreading the loaded compost.

(Prior art) Compost spreaders with a spreading device for spreading compost include a tractor-pulled type that is pulled by a tractor;
There are two types: a vehicle-mounted type that is mounted on a transport vehicle, and a self-propelled type, but in either case, when loading compost, you have to go out of your way to load the compost with a fork, etc., which is very time-consuming and time-consuming. It was inefficient.

(Purpose of the invention) The object of the invention is to provide a compost spreader that can load compost without getting off the tractor.

(Structure of the invention) The present invention includes a mounting part that can be attached to a three-point link extending from the rear of a tractor, a floor conveyor installed along the floor, and a pair of rear and A guide plate for guiding the compost to the floor conveyor is provided at a rear opening facing the mounting portion, and a guide plate is provided at a rear opening opposite to the mounting portion. A pair of beaters, which rotate in the opposite direction to the rotation direction of the floor conveyor drive shaft, are installed above and below the side opening. The pile is then loaded by moving the tractor forward, and the floor conveyor is driven to feed the compost toward the side opening, and the beater spreads the compost.

The present invention will be explained below with reference to the embodiments shown in the drawings. As shown in FIG.
As shown in Figures 2 to 4, the floor frame 4
A front plate 5 provided around this floor frame 4, a side plate 6 adjacent to this front plate 5, a rear opening 7 provided at a position opposite to the front plate 5, and a rear opening 7 provided opposite to the side plate 6. A side opening 8 is provided at a position facing the front side.

A floor conveyor 9 is installed along the floor surface of the floor frame 4, and the loaded compost is conveyed through the side opening 8.
It is now being supplied to The conveyor 9 is
It is equipped with an endless chain belt 10 such as two rows of detachable chains arranged parallel to the front plate 5, and a plurality of feed bars 11 attached to the belt 10 orthogonally thereto. belt 1
0 is a side plate 6 and a side opening 8 as shown in FIG.
The sprocket 12 is wound around a sprocket 12 disposed near each of the sprockets and the sprocket. These sprockets 12 are the third
As shown in the figure, both ends are pivotally supported by a floor conveyor drive shaft 13a rotatably attached to the floor frame 4 and a floor conveyor driven shaft 13b. This floor conveyor drive shaft 13a has a ratchet gear 14.
is attached, and the gear 14 is driven by a drive means 15, which will be described later.

A vertical frame 16 supported by the floor frame 4 is erected at the boundary between the rear opening 7 and the side opening 8, and the frame 16 has two rotating shafts 17.
One ends of the rotating shafts 17a, 17b are attached to be rotatable up and down, and the other ends of the rotating shafts 17a, 17b are rotatably held on the side opening 8 side of the front plate 5. As shown in FIG. 4, a plurality of blade-shaped beaters 18 are attached to the rotating shafts 17a and 17b, and the beaters 18 scatter the compost on the floor conveyor 9 from the side opening 8. It's becoming like that. As shown in FIG. 3, a chain 20 is wound around slave sprockets 19a and 19b attached to the rotating shafts 17a and 17b, and this chain 20 is rotated around a shaft 21 attached to the front plate 5. The slave sprocket 22, which is freely held, is wound around the driving sprocket 35 attached to the input shaft 23. The input shaft 23 is
PTO (Power Take) of tractor 1 (not shown)
Off) and are connected by a universal joint (not shown) and driven to rotate.

The power from the input shaft 23 is transmitted to the floor conveyor drive shaft 13a of the ratchet gear 14 via the drive means 15 described above. That is, the eccentric cam 24 is attached to the slave sprocket 22.
A connecting rod 25, which is a pair of rods 25a and 25b rotatably connected to each other, is rotatably attached to each of the cam 24 and the rotating shaft 13, and the ratchet gear 14
is rotated in the opposite direction to the rotating shafts 17a and 17b by meshing with a feed pawl 26 attached to the rod 25b.

As shown in FIG. 1, from the rear of the tractor 1 there are three links, namely one top link 27a and two lower links 27b and 27c.
A point link 27 extends, and the spreader main body 3 is connected to the three-point link 27 via a mounting portion 28 provided on the front plate 5. This mounting portion 28 includes a pair of lower link pins 28a and 28b that are arranged at a predetermined interval and located at approximately the same height from the floor conveyor 9, and a top link pin 29 provided above the front plate 5. It consists of The pin 29 is attached to a pair of support members 30 erected on the top of the front plate 5, and the members 30 are firmly held by a stay 31 whose tip is fixed to the spreader body 3. ing.

A guide plate 32 for guiding the compost onto the floor conveyor 9 is attached to the lower part of the rear opening 7 provided at a position facing the front plate 5 . A rod-shaped claw may be attached to this guide plate 32.
Note that 33 holds the guide plate 32 and prevents the compost from falling.

Next, we will discuss how to use the spreader according to the above configuration. First, when loading the compost 34 accumulated at a predetermined location as shown in FIG. 1, the lower link 27 of the three-point link 27 is
By lowering b and 27c, the spreader main body 3 is moved down, and then the tractor 1 is driven backwards to push the guide plate 32 into the compost 34, and the compost 34 is guided by the guide plate 32 and spreads onto the floor. It is loaded onto the conveyor 9. Once loading is complete,
When the spreader main body 3 is raised and the input shaft 23 is driven while driving the tractor 1 forward, the slave sprockets 19a and 19b rotate through the chain 20, the beater 18 rotates together with this, and the slave sprocket 22 rotates. As a result, the ratchet gear 14 rotates, and the floor conveyor 9 is driven. As a result, the compost is supplied to the side opening 8 and is fed to the side opening 8 by the beater 18.
It will be distributed from

(Effects) As is clear from the above, since the present invention has a rear opening and is equipped with a guide plate, it is possible to load compost by backing up the tractor. Therefore, there is no need to take the trouble to get off the tractor, which improves work efficiency.

In addition, by installing the beaters in two stages (upper and lower), compared to the conventional single-stage beater, the space in which the beaters rotate can be smaller, which reduces the resistance of the compost and prevents compost from clogging the beaters. This allows the compost to be finely ground and spread. Moreover, because the conventional beater rotated in the same direction as the conveyor drive shaft, the compost was often scattered onto the conveyor section on the opposite side of the opening, which was a problem. Since the compost is not scattered and the compost does not return to the conveyor side, highly effective spreading can be achieved.

Furthermore, since the compost is spread from the side, the spread area is significantly increased compared to conventional backward spreading.
