[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when the above device is used, the bolts may be loosened due to vibration, and the loose bolts may cause shaking between the connecting parts, thereby affecting the stability of the entire vehicle structure and possibly making the vehicle unstable during driving. In view of this, we propose an agricultural machinery hub unit. Utility Model Content

[0006] The purpose of the utility model is to provide an agricultural machinery hub unit to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides an agricultural machinery hub unit, which is rotatably connected to a corresponding power slot, and the top end of the ratchet wheel penetrates the corresponding power slot and extends to the outside;

[0008] A plurality of limit assemblies, each of which is located in a plurality of power slots and is used to limit the rotation direction of a plurality of ratchets;

[0009] Two rotating plates, both of which are rotatably mounted on the circumferential side wall of the hub unit body, a sliding groove 1 is provided in the rotating plate, and two sliding bars are slidably mounted in the sliding groove 1;

[0010] Two driving components are respectively located in the two rotating plates and are respectively used to drive the four sliding bars to slide.

[0011] In the present technical solution, a protective plate is placed on one side of the hub unit body, and then a number of sleeves are respectively located on one side of a number of hexagonal nuts, and then a number of ratchets are respectively rotated, and the ratchets drive the corresponding sleeves to rotate. When the sleeves are rotated to a suitable position, the personnel rotate the two rotating plates to rotate them to the spokes of the corresponding hub unit body. Through the set driving assembly, the corresponding two sliding bars can be driven to slide and approach each other, and then the two sliding bars can be fixed on the spokes of the hub unit body, further allowing the overall device to be fixed on the hub unit body. At the same time, a number of sleeves are respectively inserted into a number of hexagonal nuts. When the car is driving, a number of hexagonal nuts will vibrate and rotate in the opposite direction, causing the hexagonal nuts to loosen. Through the set limit assembly, the ratchet can only rotate in the forward direction. Under the limit of the ratchet, the corresponding hexagonal nut cannot rotate in the reverse direction, further preventing the number of hexagonal nuts from loosening when the car is driving.

[0012] In the above technical solution, further, it also includes:

[0013] The sliding groove 2 is arranged on the top of the protective plate, a handle is rotatably installed in the sliding groove 2, two torsion springs 1 are mounted on the handle, and the two ends of the torsion spring 1 are respectively fixed to the inner wall of the sliding groove 2 and the handle.

[0014] In this technical solution, after the hub unit body is installed on the car, the operator first pulls the handle to rotate it upward, and at the same time, the two torsion springs are twisted;

[0015] When the handle is released, the handle will rotate downward and enter the sliding groove 2 under the torsional force of the two torsion springs.

[0016] In the above technical solution, further, the limit assembly includes:

[0017] A pawl is rotatably mounted in the power slot, and the pawl is located on one side of the ratchet wheel, one end of the pawl extends between two adjacent teeth of the ratchet wheel, and a torsion spring 2 is sleeved on the upper end of the pawl, and the two ends of the torsion spring 2 are respectively fixed to the inner wall of the power slot and the pawl.

[0018] In the present technical solution, a protective plate is placed on one side of the hub unit body, and then a number of sleeves are respectively located on one side of a number of hexagonal nuts, and then a number of operating levers are respectively rotated, and the operating levers drive the corresponding ratchet and sleeve to rotate. When the sleeve is rotated to a suitable position, the personnel rotates the two rotating plates to rotate them to the spokes of the corresponding hub unit body. Then, a number of sleeves are respectively inserted into a number of hexagonal nuts at the same time. When the car is driving, the number of hexagonal nuts will vibrate and rotate in the opposite direction, causing the hexagonal nuts to loosen. However, under the action of the torsional force of the torsion spring, one end of the corresponding pawl is stuck between two adjacent teeth of the ratchet, so that the ratchet can only rotate in the forward direction. Under the limit of the ratchet, the corresponding hexagonal nut cannot rotate in the reverse direction, and further prevents the number of hexagonal nuts from loosening when the car is driving.

[0019] In the above technical solution, further, the driving component includes:

[0020] A threaded rod is rotatably installed in a sliding groove, one end of the threaded rod passes through two sliding bars and extends to the outside together with the sliding groove, the threaded rod is provided with two sections of threads with opposite rotation directions, and the threaded rod is threadedly connected to the two sliding bars.

[0021] In this technical solution, the two threaded rods are rotated separately. Under the action of the threads, the threaded rods drive the corresponding two sliding bars to slide and approach each other. Then the two sliding bars can be fixed on the spokes of the hub unit body, and the overall device can be further fixed on the hub unit body.

[0022] In the above technical solution, further, an operating rod is fixedly mounted on the top end of the ratchet.

[0023] In the technical solution, an operating lever is provided to facilitate personnel to rotate the ratchet.

[0024] In the above technical solution, further, the cross-section of the handle is U-shaped, and the cross-section of the sliding bar is L-shaped.

[0025] In this technical solution, it is convenient for personnel to rotate the handle so that two adjacent sliding bars can be fixed on the spokes of the hub unit body.

[0026] In the above technical solution, further, the sleeve, the corresponding ratchet and the corresponding operating rod are an integrally formed structure.

[0027] In this technical solution, the stability of the sleeve, the ratchet and the operating rod during use is ensured.

[0028] The beneficial effects of the utility model are:

[0029] 1. The agricultural machinery hub unit can drive the corresponding two sliding bars to slide and approach each other through the provided driving assembly, and then the two sliding bars can be fixed on the spokes of the hub unit body, so that the whole device can be fixed on the hub unit body.

[0030] 2. The agricultural machinery hub unit places a protective plate on one side of the hub unit body, and then a number of sleeves are respectively located on one side of a number of hexagonal nuts, and then a number of ratchets are respectively rotated, and the ratchets drive the corresponding sleeves to rotate. When the sleeves are rotated to a suitable position, the personnel rotate the two rotating plates to rotate them to the spokes of the corresponding hub unit body, and a number of sleeves are respectively inserted into a number of hexagonal nuts. When the car is driving, the number of hexagonal nuts will vibrate and rotate in the opposite direction, causing the hexagonal nuts to loosen. Through the setting of the limit assembly, the ratchet can only rotate in the forward direction. Under the limit of the ratchet, the corresponding hexagonal nut cannot rotate in the reverse direction, and further prevents the number of hexagonal nuts from loosening when the car is driving.
