Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a novel wheel for agricultural machinery. Background Art

[0002] Agricultural machinery refers to a general term for various mechanical equipment used in agricultural production. Drivers can drive agricultural machinery to operate on crops, which can speed up the efficiency of crop operations.

[0003] Currently, agricultural machinery equipment all operates through the movement of wheels. In rainy weather, the wheels of agricultural machinery equipment are very likely to sink into deep mud pits or collapsed areas during movement. After sinking into the mud pits, the wheels cannot contact the ground and slip, making it impossible for the entire agricultural machinery equipment to move. It can only wait for large-scale handling equipment such as cranes to lift the agricultural machinery, which affects the efficiency and effectiveness of the agricultural machinery equipment. Utility Model Content

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A new type of wheel for agricultural machinery includes a traction shaft driven by the agricultural machinery, a moving wheel and a placement frame fixedly mounted on the traction shaft, and a bracket and a baffle fixedly mounted on the placement frame, a movable sleeve on the traction shaft is provided with a sliding sleeve, and the sliding sleeve is movably mounted with connecting rods equidistantly distributed in the circumferential direction, a movable sleeve on the traction shaft is provided with a limit plate that is movably opposed to the sliding sleeve, and a return spring that cooperates with the traction shaft is welded between the limit plate and the baffle, a support plate for supporting the moving wheel is fixedly mounted on the connecting rod, and a drive component for driving the sliding sleeve is installed in the bracket.

[0007] Preferably, the driving assembly includes a hydraulic cylinder fixedly installed in the bracket, and a pressure cylinder corresponding to the sliding sleeve is fixedly installed at the output end of the hydraulic cylinder.

[0008] Preferably, the placement rack is a circular structure with a hollow interior, and the baffle is vertically arranged at one side of the traction shaft.

[0009] Preferably, the sliding sleeve is a circular structure with two ends open, and the end of the connecting rod away from the support plate is connected to the sliding sleeve pin.

[0010] Preferably, the support plate and the connecting rod extend to a side position outside the placement rack, and the support plate is an arc-shaped structure adapted to the moving wheel.

[0011] Preferably, a guide rod corresponding to the connecting rod is fixedly mounted on the baffle, and a guide hole for guiding the guide rod is provided on the connecting rod.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The utility model uses the extension and retraction of the output end of the hydraulic cylinder to make the connecting rod drive the support plate to gradually become vertical during the extension process, so that the moving wheel can be raised, and then the multiple support plates are in contact with the ground to prevent the moving wheel from sinking into the mud and slipping and being unable to move, so that the agricultural machine can operate on crops.

[0014] 2. The utility model can intercept the movement and deflection of the sliding sleeve and the connecting rod by arranging a baffle in the placement frame, so that the connecting rod is in a vertical state under the action of the baffle and the pressure cylinder.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figures 1-4 A novel wheel for agricultural machinery includes a traction shaft 1 driven by the agricultural machinery, a moving wheel 2 and a placement frame 3 are fixedly mounted on the traction shaft 1, and a bracket 4 and a baffle 5 are fixedly mounted on the placement frame 3. It should be noted that the agricultural machinery can drive the traction shaft 1 to rotate, which is an existing technology;

[0022] The placement frame 3 is a circular structure with a hollow interior, and the baffle 5 is vertically arranged on one side of the traction shaft 1. A sliding sleeve 6 is movably mounted on the traction shaft 1, and connecting rods 7 equidistantly distributed in the circumferential direction are movably mounted on the sliding sleeve 6. A guide rod corresponding to the connecting rod 7 is fixedly mounted on the baffle 5, and a guide hole for guiding the guide rod is provided on the connecting rod 7. The guide hole guides and limits the guide rod. By setting the baffle 5, the deflection angle of the connecting rod 7 can be limited, thereby ensuring the movement range of the connecting rod 7.

[0023] The movable sleeve on the traction shaft 1 is provided with a limit plate that is movably opposed to the sliding sleeve 6, and a return spring that cooperates with the traction shaft 1 is welded between the limit plate and the baffle 5. The return spring resets the limit plate and the sliding sleeve 6. When the sliding sleeve 6 is in an unloaded state, the return spring can pull the limit plate and the sliding sleeve 6 back to the initial position. A support plate 8 for raising the moving wheel 2 is fixedly installed on the connecting rod 7. The sliding sleeve 6 is a circular structure with openings at both ends. The pressure cylinder 10 applies pressure to the sliding sleeve 6, so that the sliding sleeve 6 can drive the connecting rod 7 to move out of the placement frame 3 during the movement and drive the support plate 8 to a vertical state. Through the mutual cooperation of multiple connecting rods 7, the support plate 8 and the ground, the moving wheel 2 can be raised as a whole, so that the driver can drive the agricultural machine to move the moving wheel 2 out of the mud pit or collapse, thereby ensuring the driver's safety and improving the efficiency of crop operations.

[0024] One end of the connecting rod 7 away from the support plate 8 is connected to the pin of the sliding sleeve 6. The support plate 8 and the connecting rod 7 extend to one side outside the placement frame 3, and the support plate 8 is an arc-shaped structure adapted to the moving wheel 2. By setting the support plate 8 to an arc-shaped structure adapted to the moving wheel 2, the contact area between the support plate 8 and the ground can be increased, so that the overall stability of the agricultural machine is guaranteed. A drive component for driving the sliding sleeve 6 is installed in the bracket 4;

[0025] The driving assembly includes a hydraulic cylinder 9 fixedly mounted in the bracket 4 , and a pressure cylinder 10 corresponding to the sliding sleeve 6 is fixedly mounted on the output end of the hydraulic cylinder 9 . The bracket 4 can protect the hydraulic cylinder 9 from rain.

[0026] The functional principle of this utility model can be explained through the following operation modes:

[0027] The driver can move the agricultural machine by moving the wheels 2;

[0028] When the moving wheel 2 encounters a deep mud pit or a collapsed area, causing the moving wheel 2 to slip and become unable to move;

[0029] The output end of the hydraulic cylinder 9 is extended and retracted, thereby causing the hydraulic cylinder 9 to drive the pressure cylinder 10 to move horizontally;

[0030] During the movement, the pressure cylinder 10 corresponds to the traction shaft 1 and applies pressure to the sliding sleeve 6, causing the sliding sleeve 6 to move horizontally on the traction shaft 1. During the movement, the sliding sleeve 6 applies pressure to the limit plate, and the return spring is compressed.

[0031] During the movement, the sliding sleeve 6 pulls the connecting rod 7 to deflect, and the connecting rod 7 can extend outside the placement frame 3 during the deflection process, so that the connecting rod 7 drives the support plate 8 to a vertical state, so that the support plate 8 supports the moving wheel 2 as a whole under the support of the connecting rod 7;

[0032] When the connecting rod 7 is in a vertical position as a whole, the guide rod can extend into the guide hole in the connecting rod 7;

[0033] The baffle 5 can limit the deflection angle of the connecting rod 7 and close the hydraulic cylinder 9;

[0034] The driver rotates the traction shaft 1 through the agricultural drive, so that the traction shaft 1 drives the moving wheel 2 and the placement frame 3 to rotate synchronously;

[0035] The placement frame 3 rotates under the support of the multiple support plates 8 during the rotation process, so that the moving wheel 2 can be moved out of the mud pit or collapse;

[0036] When the moving wheel 2 moves to the ground, the output end of the hydraulic cylinder 9 contracts, so that the sliding sleeve 6 returns to the initial position under the action of the return spring, allowing the multiple support plates 8 to return to the initial position.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
