Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an agricultural working machine that simultaneously performs crushing of iron, intercultivation, weeding, soil cultivation, etc.

Traditionally, on large-scale farms, various tasks such as fertilization, disinfection, weeding, and inter-tilling are carried out using tractor-pulled work equipment, so tractors and work equipment often come into the field. It is well known that iron-rich soil solidifies. As a countermeasure to this problem, it is well known to carry out so-called subsoiling, which involves digging deep into the soil and crushing the subsoil in order to crush and soften the solidified soil and improve the circulation of air and water. In this case, if a working machine dedicated to the subsoiler is towed by a tractor and entered into the field, the number of people coming out will increase, which will further solidify the soil and reduce the crushing effect accordingly. For this reason, some cultivators that stir soil near the ground surface to perform inter-cultivation and weeding are equipped with automatic elevation devices to function as subsoilers, but the claws depend on the weight of the automatic elevation device, the strength of the springs, and the claws themselves. Since the blade pierces the soil due to the applied resistance, the height position is unstable, and when it hits extremely hard soil, it floats up and has the problem that it cannot be expected to have a crushing effect.

OBJECTS OF THE INVENTION The present invention solves these problems and provides an agricultural working machine that can reliably crush subsoil and at the same time perform inter-tilling, weeding, soil cultivation, and other operations stably at a constant depth. With the goal.

Structure of the Invention The agricultural working machine of the present invention includes a finger member connected to a tractor, a crushing rod for deep cultivation fixed to the finger member, and a frame member attached to the finger member so as to be movable up and down. An embodiment characterized in that the frame member is provided with a working tool that is removably equipped.Example Next, an embodiment of the present invention will be described based on the drawings. A base plate 3 having two parallel plates 3a13a is fixed to the finger member 2 extending left and right with respect to the direction of movement by a bolt rod 4 and a presser plate 5 protruding from the base plate 3a. That is, the base plate 3 and the press plate 5 are brought into contact with the front and rear sides of the finger member 2, and the nut 6 is screwed into the bolt rod 4 passing through the press plate 5 and tightened. For example, three pieces are fixed at equal intervals in the center and on the left and right sides thereof. A mounting base 8 is fixed to the substrate 3 by a plurality of shear pins 7, for example, two shear pins 7, and a crushing rod 10 is inserted into the vertical through hole 9 and fixed with a set screw 11, and this crushing rod 10 is inserted deep into the ground. It is penetrated and deep plowing is performed.

Arms 12 and 13 are attached to pins 12 at both upper and lower ends of the mounting base 8, respectively.
The arms 12 and 13 are rotatably attached to each other by pins 12b and 113b, respectively, and the ends of the arms 12 and 13 are rotatably attached to the connecting arm 14 extending in the vertical direction by pins 12b and 113b, respectively. The upper and lower arms 12 and 13, the mounting base 8, and the connecting arm 14 form a parallelogram link mechanism 15, and the arm 1

is inserted.

The lower end of the connecting arm 14 is rotatably connected by a pin 17 to an approximately central portion of a frame member 16 consisting of two parallel elongated plate-shaped frame pieces 16a, 16a extending in the direction of movement. A spring 18 is stretched between the frame member 16 and the frame member 16 so that the rear part of the frame member 16 floats and the front part of the frame member 16 is pushed down. However, the frame part shrine 16 may be fixed to the connecting arm 14. The frame pieces 16a, 16a have a large number of attachment holes 19 at appropriate intervals in the front-rear direction, and necessary working tools are attached to predetermined positions of the frame member 16 using the attachment holes 19.

At the front end of the frame member 16, a wheel mounting block 20 is sandwiched between the frame pieces 16a, 16a, and is fixed by a bolt 21 inserted through the mounting hole 19 and the block 20, and the wheel 2 is fixed to the front end of the frame member 16.
2 is supported on this block 20.

At the center of the frame member 16 is a block 23 for attaching the connecting arm.

The claws 35, 36, 37, and 38 located on the left and right sides are located at different positions in the front and back and left and right with respect to the traveling direction, and are arranged in a staggered manner when viewed from the plane. .31 protruding arm 25a.

27a, 29a, and 31a. Further, the front and rear intervals of the winter melons 35, 36, 37, 38, and 39 are approximately equal to each other, and the left and right intervals are also approximately equal to each other.

The finger member 2 consists of a central main beam piece 40 and auxiliary beam pieces 41 and 41 inserted into both ends thereof. Each finger member 2 has a base plate 3, a mounting base 8, a link mechanism 15, and a frame member 16. There is.

Furthermore, the main girder piece 40 and the auxiliary girder pieces 41 and 41 are hollow with a square cross section, one ridgeline is located above, and the remaining ridgelines are located below and in the front and rear. Auxiliary girder pieces 41 and 41 are attached by screws 42 screwed into the
By fixing the length of the finger member 2, the length of the finger member 2 can be arbitrarily adjusted.

Further, a unit work machine 4 is constructed by equipping a frame member 16 attached to the above-mentioned board 3 with a link mechanism 15 and equipped with a work tool.
3 can be provided in any number on the finger member 2, not only the king pedestal, and the interval between them can also be adjusted arbitrarily.

In the above embodiment, the working implement is a claw 35 for intermediate tillage and weeding.
36, 37, 38, and 39 are shown as examples, but when installing the soil impeller, the block 44 is attached to the rear of the crushing rod 10 using the bolt 4.
5 to the frame member 16, and this block 44 may be fixedly equipped with a cultivating soil blade 46. In this case, only the right and left inner claws 35 and 36 are installed to remove the soil dug up by the cultivating soil blade 46. Make sure to soften it beforehand (Figure 5)
.

Note that the claws 35, 36, 31, 38, 39, soil blades 46, and other working tools may be mounted directly on the frame member 16.

Effects of the Invention According to the configuration of the present invention, when the unit working machine 43 is towed by a tractor and travels slowly, the frame member 16 attached to the finger member 2 connected to the tractor so as to be movable up and down can move around the unevenness of the ground surface. The frame member 16 can move up and down freely to maintain a constant distance from the ground surface, and therefore, the working tools attached to this frame member 16 are inserted into the soil to a certain depth, stabilizing inter-tilling, weeding, cultivating, and other operations. It can be done well and reliably (see 61M [).

In addition, since the crushing rod 1o is fixed to the finger member 2 separately from the frame member 16, it does not float up depending on the soil quality, and is always inserted deeply to perform deep plowing. After crushing and softening the soil, intercultivation, weeding,
By cultivating soil, etc., the resistance of the soil to the working equipment is reduced and the effectiveness of the work is improved.Furthermore, since the subsoiler, cultivator, and other working equipment are towed at the same time, the number of times people visit the field is reduced. By reducing this amount, we can expect effects such as reducing soil solidification, streamlining and improving work efficiency, and saving energy.

Furthermore, if the traction resistance is large and the tractor tires slip, the crushing rod 1o can be pulled out to a shallow position of -10- by lifting the finger member 2 to escape, and in this case as well, the frame member 16 is Since it is movable, it remains in a fixed position relative to the ground surface, allowing work to continue in the same condition as before the slip.
