Description

[Detailed Description of the Invention] The present invention is an invention related to a tractor working machine.

Among working machines, this invention is particularly related to manure hawks for transporting fibrous fertilizers such as compost.

The compost made by piling up straw after threshing and cut weeds with household mulch must be uniformly scattered over the field before paddy fields are cleared and plowed in early spring. Your Sprester and Man Your Hawk are used. Front loaders and back loaders, which are used for transporting earth and sand, are sometimes used for transporting compost as tractor implements, but immature compost is not suitable for shovels because its fibers have not broken up. It is difficult to scoop it up with a conveying device, so a piercing-type conveying device such as a manure hawk is used.

The present invention allows the hawk part to be freely tilted in conjunction with the vertical movement of the manure hawk when working with the manure hawk. As a result, when unloading the compost after transport, it can be unloaded automatically without using any human power, which saves manpower.

The purpose of the present invention is as described above, and the structure of the present invention will be explained based on the attached drawings showing embodiments.

FIG. 1 is an overall view of the manure hawk attached to the rear of tractor A.

A top link pivot 1 is attached to the tip of a top link 16 of a three-point link type work equipment mounting device at the rear of a tractor. The top link support body 1 has a plurality of top link support holes 1a, which are used to adjust the height. Furthermore, lower link 1
The tip of 7 is pivotally connected to the lower link pivot 2 of the manure hawk. A pair of lower links 17 and lower link pivots 2 are provided on the left and right, and a lift link 21 pivotally supported at the tip of a lift arm 20 is pivotally connected to a midway portion of the lower link 17. The lift arm is moved up and down by a hydraulic cylinder, moving the entire manure hawk up and down.

Figure 2 is a side view of the Manure Hawk when it is loaded.
FIG. 3 is a side view of the manure hawk at the time of unloading.

When loading, the support rod 9 should be suspended and the hawk 1
When the manure hawk is lowered by the lift arm 20 and the tractor A is moved backward at the same time with the hawk base 11 and the hawk base 11 both horizontal, the support rod 9 is laid down as shown by the chain line, and the hawk 1 is lowered.
0 can be positioned parallel to the ground. The tractor A is moved backwards as it is, the hawk 10 and the hawk base 11 are stuck into the compost pile, and the compost is loaded onto the hawk 10. Thereafter, the entire manure hawk is lifted by the lift arm 20, and the tractor A is driven to transport it to the destination.

When unloading, when the lift arm 20 is rotated downward while the compost is still in the same position, the support rod 9 in the manure hawk comes into contact with the ground surface first, and when the manure hawk is further lowered at that position, the support rod 9 The hawk base 11 is rotated about the pivot point 7a of the support 7, and the hawk 10 and the hawk base 11 are tilted as shown in FIG. After the hawk base 11 rotates to a certain extent, it engages with the stopper 13 and its rotation is stopped. The Hawk 10
The compost falls due to the inclination of the hawk base 11.

FIG. 4 is a side view of the hawk 10 and the hawk base 11, and FIG. 5 is a front view thereof.

A receiving plate 18 is provided on the rear surface of the hawk base 11 to prevent compost and the like from moving further rearward. The support rod 9 is a U that is pivotally supported at both ends of the base side of the hawk base 11.
It is shaped like a letter and always tries to droop due to gravity. The hawk 10 is welded and fixed to a hawk mount 12 fixed to the ventral surface of a hawk base 11.
Connect the pivot point 11a provided at the tip of the hawk base to the support 7.
It is pivoted by a pivot pin 7a.

FIG. 6 is a side view of the support base 7, and FIG. 7 is a front view of the same.

The abutment 7 is horizontally protruded from the lower part of the side plate 4, and the side plates 4 are reinforced and connected by a reinforcing body 8. Disassemble the side plate into parts 4 and 3, and attach the coupling fittings 6 and 1.
The reason for the complicated shape of joining at 4 and 15 is that the manure fork can be removed at these joining fittings 6, 14 and 15 and replaced with a back shovel device. The stopper 13 projects obliquely upward from the upper part of the side plate 4.

FIG. 8 is a side view of the rear plate 5, and FIG. 9 is a front view thereof.

A top link support 1 and a lower link support 2 are fixed to the rear plate 5. The mounting height is adjusted by a pivot hole 1a drilled in the upper part of the top link pivot body 1. The rear plate portion and the abutment 7 portion are connected by the connecting metal fittings 14 and 15 provided on the side plate 3 and the connecting metal fitting 6 provided on the side plate 4.

As described above, the present invention divides the manure hawk, which is vertically movably supported by a hydraulic device at the rear of the tractor, into the hawk base 11 and the support 7, and the pivot pin 7a of the support 7 connects the hawk base 11 to the hawk base 11. Hawk 10
It pivots the unevenly distributed position on the side, and usually the hawk base 1
1 is configured to be placed horizontally on a support 7, a support rod 9 is pivoted closer to the tractor than the pivot pin 7a of the hawk base 11, and the manure hawk is raised by the tractor, Since the support rod 9 is suspended below the hawk base 11 by its own weight, the following effects are achieved.

First, by moving the tractor backwards while lowering the manure hawk, it is possible to stick the hawk into the compost and load it.Also, when unloading, just by rotating the lift arm downward, the support rod is stretched and the hawk is tilted. The driver can now load and unload compost while remaining seated in the driver's seat by simply moving the tractor forward and backward and moving the lift arm up and down.
Also, there was no need to add power to tilt the hawk.

Claims (1)

[Scope of utility model registration request] A manual hawk, which is supported vertically and movably by a hydraulic system at the rear of the tractor, is divided into two parts, a hawk base 11 and a pedestal 7, and the pivot pin 7a of the pedestal 7 is located unevenly on the hawk 10 side of the hawk base 11. Normally, the hawk base 11 is configured to be placed horizontally on the pedestal 7, and the support rod 9 is pivoted on the tractor side with respect to the pivot pin 7a of the hawk base 11. Then, when the manure hawk is raised by the tractor, the support rod 9 is moved to the hawk base 11 by its own weight.
A manure hawk for tractors that is characterized by hanging downward.
