Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a semi-suspension intelligent reversible plough with shock-absorbing wheels. Background Art

[0002] Among the semi-mounted reversible plows currently on the market, only simple soil turning is possible and their functions are single. When a reversible plow with a longer plow rotates at the edge of the field, it needs to be straightened by a tractor, resulting in a large area of ​​land being left uncultivated at the edge of the field. At the same time, the operating depth cannot be automatically controlled, and the turning radius at the edge of the field is too large, which wastes working time, is inefficient, and lacks intelligent functions. Summary of the invention

[0003] The purpose of the present invention is to solve the above-mentioned problem and to provide a semi-suspension intelligent reversible plow with shock-absorbing wheels, so that the plowing operation becomes simpler and faster.

[0004] The technical solution adopted by the present invention is: a semi-suspension intelligent flip plow with shock-absorbing wheels, comprising a plowshare assembly, a wheelbase automatic matching adjustment block, a lifting structure assembly, a main beam, a secondary beam, a plowshare assembly, a tail wheel assembly and a tail beam assembly; the plowshare assembly is horizontally hinged with the wheelbase automatic matching adjustment block, and a correction cylinder is provided between the plowshare assembly and the wheelbase automatic matching adjustment block; the wheelbase automatic matching adjustment block is connected to the lifting mechanism connecting block through a wheelbase adjustment connecting rod and a wheelbase adjustment cylinder; a lifting structure assembly is installed on the lifting mechanism connecting block; the flip structure assembly is connected to the rear of the lifting structure assembly, and the flip structure assembly uses the secondary beam as the rotation axis, and the flipping of the main beam is controlled by a flipping two-stage cylinder; the end of the secondary beam is connected to the tail wheel assembly; the plowshare assembly is installed on the main beam, the front wheel assembly is installed on the main beam, and the tail end of the main beam is connected to the tail beam assembly; a beam reinforcement connecting rod is installed between the main beam and the secondary beam.

[0005] Furthermore, the tail wheel assembly includes a tail wheel assembly lifting cylinder and a tail wheel lifting connecting rod, and the tail wheel lifting cylinder and the tail wheel lifting connecting rod are arranged in parallel.

[0006] Furthermore, the tail wheel assembly lifting cylinder adopts a hydraulic damper to provide the tail wheel assembly with a shock absorbing effect.

[0007] Furthermore, the lifting structure assembly includes a lifting cylinder and two lifting connecting rods, the two lifting connecting rods are installed in parallel, and the lifting cylinder can drive the lifting connecting rods to move.

[0008] Furthermore, the flip structure assembly includes a flip connecting rod assembly and a flip limit adjustment bolt. The flip connecting rod assembly is installed at the connection between the flip structure assembly and the lifting structure assembly. One end of the flip two-stage oil cylinder is connected to the main beam, and the other end is connected to the end of the flip connecting rod assembly; the flip limit adjustment bolt is correspondingly installed below the flip connecting rod assembly.

[0009] Furthermore, the lifting cylinder can cooperate with the tail wheel lifting cylinder to raise or lower the overall vertical level of the plough.

[0010] The beneficial effects produced by the present invention are:

[0011] 1. The present invention can adjust the beam height as a whole by lifting the structural assembly and the tail wheel assembly, thereby ensuring the smooth emergence and entry of the plowshare into the soil and adjusting the tillage depth.

[0012] 2. The tail wheel assembly with hydraulic damper can reduce the shock of the plow, reduce the up and down vibration amplitude of the plowshare, and improve the convenience of transporting the plow.

[0013] 3. The correction cylinder can adjust the tractor and the plow to form a straight line, forcing the plow to correct its posture, so that the tractor can still move the plow to the working position after turning around, reducing the turning radius. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] The present invention is a semi-suspension intelligent reversible plow with shock-absorbing wheels. Figure 1 and Figure 2 The figure is a schematic diagram of the structure in the plowing state, and its main structure includes a plowshare assembly 1, a wheelbase automatic matching adjustment block 2, a lifting structure assembly 7, a main beam 18, a secondary beam 12, a plowshare assembly 17, a tail wheel assembly 14 and a tail beam assembly 16. The plowshare assembly 1 is horizontally hinged with the wheelbase automatic matching adjustment block 2, so that the wheelbase automatic matching adjustment block 2 can swing left and right relative to the plowshare assembly 1.

[0022] A correction cylinder 3 is provided between the plowshare assembly 1 and the wheelbase automatic matching adjustment block 2; the correction cylinder 3 can adjust the position of the plow and force the plow to correct its posture; when the plow runs to the ridge head, the tractor needs to turn around, but due to the length of the plow, the plow is not straightened when the tractor reaches the working position after turning around. At this time, if the tractor moves forward to correct the plow position, part of the plowing will be lost; at this time, if the correction cylinder 3 is used to push the wheelbase automatic matching adjustment block 2, the beam can be turned straight and the plowshare can be put back into the working position. During the forward movement of the plow, the correction cylinder 3 is always in a pressure relief state.

[0023] The wheelbase automatic matching adjustment block 2 is connected to the lifting mechanism connecting block 6 through two parallel wheelbase adjustment links 4, and the wheelbase adjustment cylinder 5 is used to control the adjustment of the wheelbase; if the wheelbase needs to be adjusted, it is necessary to ensure that the correction cylinder 3 is pressure-locked, and then control the movement of the wheelbase adjustment cylinder 5 to ensure that the wheelbase adjustment link 4 swings to achieve the translation of the beam.

[0024] The lifting structure assembly 7 is installed on the lifting mechanism connection block 6, and the flip structure assembly 10 is connected to the rear of the lifting structure assembly 7. The lifting structure assembly 7 includes a lifting cylinder 8 and two parallel lifting connecting rods 9. The lifting connecting rods 9 are installed above the lifting mechanism connection block 6. The lifting cylinder 8 drives the lifting connecting rods 9 to move the lifting structure assembly 7 up and down, driving the flip structure assembly 10, and cooperating with the tail wheel assembly 14 to meet the adjustment of the plowshare's plowing depth. At the same time, it can also move separately with the tail wheel assembly 14 to achieve the plowshare's emergence and entry into the soil. For example, when emerging from the soil, the lifting cylinder 8 drives the lifting connecting rod 9 to move, and the tail wheel lifting cylinder 141 in the tail wheel assembly 14 does not move, so that the front part of the plow is lifted as a whole, so that the plowshare is sequentially emerged from the soil, ensuring that the triangular area in the field is fully plowed and reducing the missed plowing area at the head of the field. The opposite is true when entering the soil.

[0025] The flip structure assembly 10 uses the secondary beam 12 as the rotation axis, and its rotation center is hinged to the secondary beam 12. The main beam 18 is flipped by two flip two-stage cylinders 11. Figure 4 As shown, the flip structure assembly 10 includes a flip connecting rod assembly 20 and a flip limit adjustment bolt 21. The flip connecting rod assembly 20 is installed at the connection between the flip structure assembly 10 and the lifting structure assembly 7 and is located on both sides thereof. One end of the flip two-stage oil cylinder 11 is connected to the main beam 18, and the other end is connected to the end of the flip connecting rod assembly 20. When the main beam 18 needs to be flipped or switched to a walking state, as shown in FIG. Figure 3 As shown, one of the two-stage flip cylinders 11 is extended and the other is shortened, thereby controlling the flip position of the main beam 18. The flip limit adjustment bolt 21 is correspondingly installed below the flip link assembly 20, and the maximum flip angle of the main beam 18 is controlled and adjusted by pressing the flip limit adjustment bolt 21 against the flip link assembly 20.

[0026] The end of the sub-beam 12 is connected to the tail wheel assembly 14; the tail wheel assembly 14 includes a tail wheel lifting cylinder 141 and a tail wheel lifting connecting rod 142, and the tail wheel lifting cylinder 141 is arranged in parallel with the tail wheel lifting connecting rod 142. The tail wheel lifting cylinder 141 adopts a hydraulic damper to make the tail wheel assembly 14 have a shock absorbing effect.

[0027] A plowshare assembly 17 is installed on the main beam 18 , a front wheel assembly 19 is installed on the main beam 18 , and a tail beam assembly 16 that can swing in parallel is connected to the rear end of the main beam 18 ; a beam reinforcement connecting rod 13 is installed between the main beam 18 and the auxiliary beam 12 .

[0028] like Figure 5 As shown, the oil cylinders in the above-mentioned invention can also be replaced by slide rails, slideways, cranks, gear rack mechanism 22, eccentric wheels or eccentric gears. The gear rack mechanism is controlled by the rack oil cylinders on both sides of the rack, thereby achieving the same effect as the correction oil cylinder.
