Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a micro rice field machine which does not sink into muddy ground. Background Art

[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete plowing and harrowing operations. Because of its strong soil crushing ability and flat ground after plowing, a rotary tiller is needed to loosen the land before sowing rice. This increases the amount of oxygen in the soil cracks, which is beneficial to seed germination and growth, and improves the disease resistance of high-quality rice seeds.

[0003] After searching, the utility model with announcement number CN220711954U belongs to the field of agricultural machinery technology, and discloses a rotary tiller for rice fields. Through the setting of a counterweight component, it can evenly increase the weight on both sides of the support frame, avoiding the problem that the user is unable to hold the rotary tiller firmly due to his or her light weight, resulting in uneven rotary tillage distances between the plow component and the land. This improves the uniformity of the rotary tillage distance of the plow component and meets the different sowing requirements of rice seeds.

[0004] The device also has the following disadvantages during use: the soil inside the rice field is relatively moist and contains a certain amount of moisture. When the rotary tiller passes through, the soil tends to stick to the tires and sink under the gravity of the machine body. When the friction between the tires and the soil is insufficient, slipping will occur, affecting the rotary tillage efficiency. In addition, the soil stuck to the tires needs to be cleaned manually, which is more troublesome. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that when the rotary tiller passes, the machine will sink under the gravity of the machine body, and when the friction between the tires and the soil is insufficient, slipping will occur, affecting the rotary tillage efficiency, and the soil adhering to the tires needs to be manually cleaned, which is relatively troublesome. A miniature rice field machine is proposed which does not sink in muddy ground.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A micro rice field machine that does not sink in muddy ground, comprising a rice field machine, and tires on both sides of the rice field machine are detachably provided with anti-skid wheels for increasing the contact area with the ground and the friction force;

[0008] The anti-skid wheel also includes a connecting plate connected to the tire of the paddy field machine through a connecting piece, the outer wall fixing sleeve of the connecting plate is provided with a connecting ring, the outer wall fixing sleeve of the connecting ring is provided with two conical frames, and the two conical frames are in an eight-shaped shape, which are used to increase the contact area with the ground;

[0009] A plurality of partitions, each of which is fixedly disposed between two conical frames, and the top of each partition protrudes from the outer wall of the conical frame to increase friction with the ground;

[0010] A plurality of cleaning mechanisms are arranged on the connecting ring and are located between two adjacent partitions and two conical frames, and are used for cleaning the dirt adhered to the connecting ring.

[0011] In a possible design, the cleaning mechanism includes a sliding rod that slides through a connecting ring, an arc-shaped plate is fixedly provided at the outer end of the sliding rod, and will be squeezed onto the connecting ring by the soil when moving, a baffle is fixedly provided at the other end of the sliding rod, and a tension spring is provided on the outer wall of the sliding rod, and the two ends of the tension spring are respectively fixedly connected to the inner wall of the connecting ring and one side of the baffle, so as to provide power for the sliding rod when the arc-shaped plate is away from the ground.

[0013] In a possible design, the connecting part includes a flange fixed on the tire of the rice field machine, a limiting ring is fixedly provided on the outer side of the flange, a connecting tube is inserted into the inner wall of the limiting ring, the other end of the connecting tube is fixedly connected to the connecting plate, a bolt is penetrated through one side of the connecting plate, one end of the bolt is provided with a threaded portion, and the threaded portion penetrates the connecting tube and is threadedly connected to the flange.

[0014] In a possible design, a plurality of pins are slidably provided through the outer wall of the connecting cylinder for use with bolts, a plurality of insertion holes corresponding to the pins are opened on the outer wall of the limiting ring, a spring located in the connecting cylinder is sleeved on the outer wall of the pin, and the two ends of the spring are respectively fixedly connected to the inner wall of the connecting cylinder and the outer wall of the pin, and the outer wall of the bolt is provided with a tapered portion and a step portion for driving the pin to extend.

[0015] In a possible design, a protective ring for protecting the tension spring is fixedly provided on the inner wall of the outer end of the connecting ring.

[0016] In a possible design, a key slot is provided on the inner wall of the limiting ring, and a positioning key used in conjunction with the key slot is fixedly provided on the outer wall of the connecting tube.

[0017] In the present application, when in use, the anti-skid wheel is pushed to one side of the rice field machine, and the rice field machine is lifted up by the jack until the limiting ring corresponds to the connecting tube and the pin is corresponding to the insertion hole, and then the anti-skid wheel is moved to drive the connecting tube to approach the limiting ring until the connecting tube is inserted into the limiting ring, and then the bolt is inserted into the connecting ring through the connecting plate. During the insertion process, the pin can be driven to move upward through the tapered part so that the pin is inserted into the corresponding one, and finally the bolt is turned so that one end of the bolt is screwed into the flange to further fix it, and the anti-skid wheel on the other side is installed in the same way;

[0018] When walking in the rice field, the two conical frames are in an outward O-shape, which increases the contact area with the ground, and can increase the friction with the ground through the partition during the movement.

[0022] In the utility model, the micro rice field machine without sinking in muddy ground is provided with an arc plate between two adjacent partitions, and the arc plate can move according to the mud, and can automatically clean the mud between the two conical frames and the two partitions during the working process without manual cleaning;

[0023] In the utility model, the contact area and friction between the rice field machine and the ground can be significantly increased through the design of detachable anti-skid wheels, which effectively prevents the rice field machine from sinking into the mud. At the same time, the setting of the cleaning mechanism can automatically clean the mud adhered to the anti-skid wheels to keep the anti-skid wheels in good working condition. In addition, the secondary fixing design of the connecting piece further enhances the connection stability between the anti-skid wheels and the rice field machine tires, thereby improving the overall safety and reliability.
