DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compost disperser configured to disperse compost by a disperser having a vertical beater shaft.

[0002]

2. Description of the Related Art The basic structure of a conventional compost spreader having a vertical beater shaft is as follows. One or more pairs of vertical beater shafts are arranged along the width direction of the bed at the rear of the bed where a floor conveyor is arranged on the floor. Vertically supported at predetermined intervals, a number of beater blades are arranged and fixed around the entire length of the vertical beater shaft, and the compost continuously conveyed to the rear of the bed by the floor conveyor is transferred to each beater. Break down by the rotating action of the blades,
At that position, it is scattered to the rear of the fully open cargo bed. For example, the compost spreader shown in FIG.
A large number of fan-shaped beater blades 32 are fixed to the outer peripheral surface of the vertical beater shaft 31 at a predetermined angle with respect to the axial direction of the vertical beater shaft 31, and what is shown in FIG.
A large number of beater blades 33 formed by bending a plate at a right angle or at an angle close thereto are arranged and fixed around the vertical beater shaft 31. Further, the compost sprayer shown in FIG. 11 is configured such that a spiral beater blade 34 is arranged around a vertical beater shaft 31 and fixed over the entire length. In any of the compost spreaders, a disc 35 having a blade is fixed to the lower end of the vertical beater shaft 31 so that the compost dropped from above is scattered rearward by the disc 35.

[0003] As described above, in the conventional compost disperser, each of a large number of beater blades arranged and fixed around the entire length of the vertical beater shaft cuts the compost continuously conveyed to the rear of the cargo bed. In addition, since the configuration is such that it is scattered behind the cargo bed that is fully open at that position, there are the following problems. (1) The beater blade fixed to the vertical beater shaft has the action of breaking down the compost at that position,
Since it has the function of scattering the cut compost, the resistance received from the compost increases due to its structure, and a large power is required to drive the vertical beater shaft. (2) When the remaining amount of compost loaded on the bed decreases,
An effect is produced in which the compost is scattered in front of the bed, which is in the direction opposite to the spraying direction. Foreign materials such as stones and wood chips are often mixed in the compost, and these foreign materials may be scattered toward the driver of the machine, which is dangerous. (3) Since the compost is scattered by all the beater blades fixed over the entire length of the vertical beater shaft, the back of the loading platform is fully open, so it is necessary to adjust the spreading width and the spreading direction of the compost. difficult.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned disadvantages of the conventional compost disperser, and has reduced the rotational resistance of the beater blade to reduce the power required for the drive rotation of the vertical beater shaft. In addition, if the remaining amount of compost is low, prevent compost and foreign matter from being scattered in front of the cargo bed to ensure the safety of the operator of this machine, and in addition to these, the spread width and spread of compost It is an object to make it easy to adjust the direction.

The partition plate 10 is comminuted by the beater blades 5 or scattered on the inner surface of the beater cover 8. The attached compost is prevented from falling directly to the field.

Next, a brief description will be given of a driving force transmission mechanism for rotating the vertical beater shaft 4 and moving the floor conveyor 3. 3 and 4, power from a tractor for towing the compost spreader is transmitted to a first transmission shaft 11, and the power of the first transmission shaft 11 is transmitted via a transmission 12 to a first transmission shaft 11. The second transmission shaft 13 is transmitted to a second transmission shaft 13 orthogonal to the shaft 11.
Is transmitted to the floor conveyor drive shaft 15 via the chain device 14, whereby the floor conveyor 3 travels. On the other hand, a bevel gear 16a attached to the distal end of the first transmission shaft 11 and a bevel gear 16 attached to the center of a beater drive shaft 17 orthogonal to the first transmission shaft 11.
and the power of the first transmission shaft 11 is transmitted to the beater drive shaft 17. A bevel gear 16c attached to each end of the beater drive shaft 17;
Is engaged with the bevel gear 16d attached to the lower end of the motor, and the rotation of the beater drive shaft 17 causes the respective vertical beater shafts 4 to be driven and rotated in opposite directions. In FIGS. 1 and 2, reference numeral 18 denotes a tire mounted on the carrier 2.
Reference numeral 9 denotes a towing rod mounted on the front of the bed 2.

To spread the compost, the floor conveyor 3 is driven and driven while the luggage carrier 2 is pulled by a tractor and travels. The compost loaded on the luggage platform 2 is loaded with the compost.
Is continuously conveyed behind. The compost conveyed to the part of the spreading device A at the rear part of the bed 2 is rotated by the rotation of the vertical beater shaft 4 which is rotating in the opposite direction, passes through the inside of the longitudinal beater shaft 4 from the side of the bed frame 1, and the compost 2 Moved to the center. In this way, while the compost is being moved to the center of the bed 2 at the rear of the bed 2, the compost is broken down by the large number of beater blades 5 fixed to the vertical beater shaft 4. Most of the compost disintegrated by the beater blades 5 falls directly onto the spreading disc 7 fixed to the lower end of the vertical beater shaft 4 and passes through the compost spreading opening 9 by its rotating and scattering action. Spread behind the loading platform 2. But,
A part of the compost disintegrated by the beater blade 5 is scattered behind the vertical beater shaft 4 and adheres and deposits on the beater cover 8 or the partition plate 10 provided horizontally at the lower end of the beater cover 8. Is dropped on the spreading disc 7 by the rotation of the sprinkling disc 7, or is dropped on the spreading disc 7 through a hole (not shown) provided in the partition plate 10, and thereafter the spreading disc 7 is
Is scattered to the rear of the loading platform 2 by the rotating scattering action of

As described above, the portion where the beater blades 5 are disposed behind the vertical beater shaft 4 has the entire width of the loading platform 2.
A beater cover 8 is provided over the
The compost disintegrated by the rotation of the sprinkler falls on the spreading disc 7 fixed to the lower end of the vertical beater shaft 4 without being sprayed backward at that position, and the rotating scattering action of the spreading disc 7 is performed. Thus, since it is configured to be sprayed to the rear of the bed 2 through the compost scattering opening 9 provided at the rear thereof, the spreading width and spreading direction of the compost can be easily adjusted.

FIG. 5 shows an example of a pair of vertical beater shafts 4.
An arc-shaped center guide 21 is disposed along the outer periphery of the scatter disk 7 between the scatter disks 7 disposed at the lower end of the scatter disk. Due to the action of the center guide 21, the amount of compost scattered behind the central portion of the bed 2 in the width direction is reduced, and the spread area of the compost on the left and right sides of the bed 2 is widened. As a result, the spread width of the compost is increased. Becomes wider. In the example shown in FIG. 6, the spray width regulating plates 22 are respectively arranged on the outer portions of the spray disks 7 arranged at the lower ends of the pair of vertical beater shafts 4. The compost that is about to be scattered to the left and right sides of the bed 2 due to the rotating scattering action of the spreading disk 7 collides with the spreading width regulating plate 22 and the spreading direction is forcibly changed, thereby narrowing the spreading width of the compost. it can. Furthermore,
In the example shown in FIG. 7, the distribution guide plate 23 is disposed between the spray disks 7 disposed at the lower end portions of the pair of vertical beater shafts 4, and compost is disposed behind the center of the loading platform 2 in the width direction. The compost is not scattered at all, and the compost is evenly scattered on the left and right sides on the rear side of the loading platform 2. As described above, in the compost spreader according to the present invention, the rear part of the bed 2 is completely open as in the conventional machine, and the length direction (height
The compost is not sprayed from all parts along the composting direction, but only from the compost spraying opening 9 formed behind the spreading disc 7 arranged at the lower end of the vertical beater shaft 4, the compost is spread behind the loading platform 2. Because of this configuration, the spread width, direction and density of the compost can be easily adjusted by simple means.

In the example shown in FIG. 8, a plurality of large-size spray blades 24 having an L-shaped cross section are radially arranged at the lower end of the vertical beater shaft 4 instead of the spray disk 7. It is of a configuration that is fixed. The function of rotating and scattering the plurality of spray blades 24 arranged radially is the same as that of the spray disk 7.
