Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to an anti-slip device for the tires of agricultural machinery. Background Technique

[0002] A tire is a circular ring-shaped elastic rubber product that is mounted on various vehicles or machinery and rolls on the ground. It is usually installed on a metal rim, can support the vehicle body, buffer external impacts, achieve contact with the road surface, and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. When driving, they are subjected to various deformations, loads, forces, and high and low temperatures. Therefore, they must have high load-bearing performance, traction performance, and buffering performance. When agricultural machinery is used on wet and muddy ground sections, anti-slip components are often installed on the tires. The existing anti-slip components use anti-slip chains to protect the tires.

[0003] When the existing agricultural machinery tires adopt anti-slip chains, most anti-slip chains are installed by sleeving around the tires to ensure anti-slip performance. After driving on normal roads, the chains need to be removed again. This makes it necessary to perform the loading and unloading operations of the chains in the working and non-working states of agricultural machinery, resulting in a long preparation time and great inconvenience. For this reason, we propose an anti-slip device for the tires of agricultural machinery. Content of the Utility Model

[0004] The content part of this application is used to briefly introduce the concepts, which will be described in detail in the following specific implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.

[0005] The purpose of the utility model is to provide an anti-slip device for the tires of agricultural machinery to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an anti-slip device for the tires of agricultural machinery, including a main body. One side of the main body is connected with a hydraulic telescopic frame, and anti-slip teeth are distributed around the hydraulic telescopic frame. The hydraulic telescopic frame includes an inner ring frame, and a motor is connected to the axis of the inner ring frame. The bottom end of the motor is connected with a screw rod, and an extrusion rod is sleeved around the screw rod. The bottom end of the extrusion rod is connected with a sealing rubber ring, and the outer wall around the sealing rubber ring is attached to a hydraulic pipe. The outer wall around the hydraulic pipe is connected with a transfer pipe, and one end of the transfer pipe is connected with a telescopic cavity.

[0007] Furthermore, the telescopic cavities and the transfer pipes are arranged in a ring around the outer wall of the hydraulic pipe, and the telescopic cavities are communicated with the hydraulic pipe through the transfer pipes.

[0008] Furthermore, the extrusion rod is tightly fitted around the inner wall of the hydraulic pipe through a sealing rubber ring, and the extrusion rod forms a transmission structure through a screw rod and a motor.

[0009] Furthermore, the main body includes a tire, and an outer ring frame is connected to an outer wall on one side of the tire, bolts are arranged on an outer wall on one side of the outer ring frame, and an inner ring frame is arranged inside the outer ring frame.

[0010] Furthermore, the outer ring frame forms a detachable structure with the tire through bolts, and the inner part of the outer ring frame is fixedly connected to the inner ring frame.

[0011] Furthermore, the anti-slip teeth include a tooth plate, and a groove is formed at one end of the tooth plate, the other end of the tooth plate is connected to a limit seat, and the outer wall around the limit seat is tightly fitted with the inner wall around the telescopic cavity.

[0012] Furthermore, the tooth plate is telescopically matched with the telescopic cavity through a limiting seat, and the grooves are opened at equal distances along the end of the tooth plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The anti-skid device is equipped with an inner ring frame in the outer ring frame where the tire is placed. The screw driving extrusion rod at the axis of the inner ring frame can squeeze the oil in the hydraulic pipe to transmit the force, so that the hydraulic pipe cooperates with the transmission pipes distributed around to transmit the pressure to the telescopic cavity to realize the telescopic adjustment process of the anti-skid teeth, thereby forming an anti-skid structure in cooperation with the anti-skid teeth of the ring cloth. When not in use, it can also be retracted and stored without disassembly, which is convenient and quick to use.

[0015] The anti-skid device is connected and fixed to the outer wall of the tire through the bolts of the outer ring frame and the surrounding ring cloth, so as to maintain the stability of the structure in the anti-skid use state, so that the agricultural machinery installed can run stably in the mud;

[0016] The tooth plate structure of the ring cloth of this device improves friction by opening grooves equidistantly at the end. At the same time, the limit seat at the other end of the tooth plate can maintain the limit position during the telescopic adjustment process to prevent it from falling out.

[0026] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0027] The present utility model provides an anti-slip device for a tire of an agricultural machine as Figures 1-4 shown, which includes a main body 1. A hydraulic telescopic frame 2 is connected to one side of the main body 1, and anti-slip teeth 3 are distributed around the hydraulic telescopic frame 2. The main body 1 includes a tire 101, and an outer ring frame 102 is connected to the outer wall of one side of the tire 101. Bolts 103 are annularly arranged on the outer wall of one side of the outer ring frame 102, and an inner ring frame 201 is arranged inside the outer ring frame 102;

[0028] In order to maintain the structural stability of the annular anti-slip teeth 3 when they extend to assist in anti-slip, as Figure 1 shown, this anti-slip device is connected and fixed to the outer wall of the tire 101 through the outer ring frame 102 and the bolts 103 annularly arranged around it, so as to maintain the structural stability in the anti-slip use state, and enable the installed agricultural machine to drive stably in the mud.

[0029] like Figures 2-3 As shown, the hydraulic telescopic frame 2 includes an inner ring frame 201, and the axis of the inner ring frame 201 is connected to a motor 202, the bottom end of the motor 202 is connected to a screw 203, and the screw 203 is sleeved with an extrusion rod 204, the bottom end of the extrusion rod 204 is connected to a sealing rubber ring 205, and the outer wall around the sealing rubber ring 205 is attached with a hydraulic pipe 206, the outer wall around the hydraulic pipe 206 is connected to a transfer pipe 207, and one end of the transfer pipe 207 is connected to a telescopic chamber 208;

[0030] In order to facilitate the switch between the protective structure and the normal driving state, such as Figures 2-3 As shown, an inner ring frame 201 is mounted in the outer ring frame 102 where the tire 101 is placed. The screw 203 on the axis of the inner ring frame 201 can drive the extrusion rod 204 to squeeze the oil in the hydraulic pipe 206 to transmit the force, so that the hydraulic pipe 206 cooperates with the transmission pipes 207 distributed around to transmit the pressure to the telescopic chamber 208 to realize the telescopic adjustment process of the anti-skid teeth 3, thereby forming an anti-skid structure with the anti-skid teeth 3 of the ring cloth, and when not in use, it can also be telescopically retracted without disassembly, which is convenient and quick to use.

[0031] like Figure 4 As shown, the anti-slip teeth 3 include a tooth plate 301, and a groove 302 is formed at one end of the tooth plate 301, and the other end of the tooth plate 301 is connected to a limit seat 303, and the outer wall around the limit seat 303 is tightly fitted with the inner wall around the telescopic cavity 208;

[0032] Finally, in order to maintain stable anti-slip properties during protective use, such as Figure 4 As shown, the tooth plate 301 structure of the device has grooves 302 equidistantly provided at the end to increase friction, while the limit seat 303 at the other end of the tooth plate 301 can maintain the limit position during the telescopic adjustment process to prevent it from falling out.

[0033] In summary, when the anti-skid device is in use, the outer ring frame 102 can be first connected and fixed to one side of the tire 101 through the ring-shaped bolts 103. When a protective effect is needed, the motor 202 can be used to drive the screw 203 to rotate, and the screw 203 drives the extrusion rod 204 connected to the bottom end to transmit the downward hydraulic pipe 206, so that the oil in the hydraulic pipe 206 is diffused along the surrounding transmission pipes 207 with the pressure until the pressure is evenly transmitted to the telescopic chamber 208. At this time, the tooth plate 301 in the telescopic chamber 208 is squeezed out with the pressure to form an external tooth structure that is ringed around the outer ring frame 102, which cooperates with the tire 101 to travel and achieve anti-skid assistance in muddy fields.

[0034] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
