Description

Technical fields:

[0001] This utility model relates to an agricultural machine, specifically a strip tiller with universal wheels for supporting movement when not in operation. Background technology:

[0002] In recent years, the area of ​​corn planted using conservation tillage techniques in my country has gradually increased, leading to the development of row tillage techniques that retain straw, improve soil fertility, and create a level seedbed with a firm subsoil, thus ensuring a high germination rate. However, existing row tillers are relatively heavy and use a suspended connection, resulting in significant impacts on the tractor during travel to the tilled area, causing damage and increasing fuel consumption. This invention provides a row tiller with a support caster wheel for non-operational travel. A support caster wheel is located in the middle of the rear of the row tiller. When traveling to the work area, this wheel is lowered for support, and it is retracted during operation, without affecting the machine's operation, effectively solving this problem. Utility Model Content:

[0003] The purpose of this invention is to provide a strip tiller with omnidirectional wheels for supporting walking when not in operation, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a strip tiller with supporting casters for non-operational movement, comprising a frame, a lower suspension frame, a gearbox, an upper suspension frame, an oil tank, a radiator, a supporting caster frame, a support shaft, a press roller, a soil covering disc, a strip tiller roller, a depth-limiting ground wheel, a deep loosening shovel, a weeding wheel, a limit nut, a stop block, a support shaft seat, a support shaft frame, a caster frame, supporting casters, a fixed pin, a pin, a hydraulic cylinder, a fixed seat plate, and a hydraulic cylinder. The machine includes a cylinder mounting plate, a support shaft mounting plate, a support shaft mounting sleeve, a support shaft bracket seat plate, a Π-shaped plate, a support shaft seat fixing plate, and a stop block fixing pin. Its characteristic is that a support travel universal wheel frame is installed at the middle of the rear of the frame, and support travel universal wheels are installed on the support travel universal wheel frame. When the machine moves towards the work site, the support travel universal wheels are lifted by a hydraulic cylinder, and the support travel universal wheels touch the ground, providing auxiliary support, reducing the load of the machine on the tractor, protecting the tractor, and saving fuel.

[0005] Furthermore, after the hydraulic cylinder lifts up the support caster, the stop block is fixed to the upper part of the support shaft with a stop block fixing pin to block the support shaft and make it play a supporting role. At this time, the support caster is in working state and the machine is in the stage of moving to the work site.

[0006] Furthermore, when the stop block fixing pin is pulled out, the stop block falls, the hydraulic cylinder retracts, and the support travel caster is lifted. The support travel caster is located above each working component. At this time, the support travel caster is in a non-working state and will not affect the operation of each working component. At this time, the machine is in the strip tillage operation state. Attached image description:

[0016] like Figures 1-7As shown, this utility model includes a frame 1. A lower suspension frame 2 and an upper suspension frame 4 are provided at the front of the frame 1, forming the suspension system of the implement. A gearbox 3 is located in the middle of the front of the frame 1, with an oil tank 5 above it. A radiator 6 is located at the rear of the frame 1, circulating and cooling the oil in the oil tank 5 after it has been used. A strip tillage roller 11 is installed in the middle of the lower part of the frame 1. A compaction roller 9 and a soil covering disc 10 are also installed at the rear of the frame 1. After strip tillage by the strip tillage roller 11, the soil is gathered onto the strip by the soil covering disc 10 and compacted by the compaction roller 9 to form a flat strip with a certain degree of compaction. Depth-limiting wheels 12 are installed on both sides of the frame 1. By adjusting the depth-limiting wheels 12... The height of the tillage roller 11 is adjusted to control its working depth. On the front of the frame 1, corresponding to both sides of the tillage roller 11, weed-removing wheels 14 are installed. These wheels remove any remaining straw from the working area, creating a better working environment for subsequent tillage operations. A deep-loosening shovel 13 is installed at the center of the front of the frame 1, corresponding to the tillage roller 11. During machine operation, the deep-loosening shovel 13 performs deep-loosening work. A support caster frame 7 is installed at the center of the rear of the frame 1. This frame is welded together from several parts, including a fixed base plate 24, a hydraulic cylinder mounting plate 25, a support shaft mounting plate 26, and a support shaft mounting sleeve 27. The hydraulic cylinder 23 is mounted on the support caster frame 7 via a pin 22. The support shaft frame 18 is... The support shaft frame 18 is welded together from a support shaft bracket seat plate 28, a Π-shaped plate 29, and a support shaft seat fixing plate 30. The support shaft frame 18 is connected to a caster frame 19, on which a support travel caster 20 is mounted. A hydraulic cylinder 23 is connected to the Π-shaped plate 29. When the hydraulic cylinder 23 extends or retracts, it simultaneously extends or retracts the support shaft frame 18, which in turn extends or retracts the support travel caster 20. When the support travel caster 20 extends, it supports the implement's movement, reducing the load on the tractor. When the support travel caster 20 retracts, it is higher than the height of the implement's working parts and is in a non-working state, while the implement is in strip tillage operation. A support shaft seat 17 is fixed to the Π-shaped plate 29 with a fixing pin 21. A support shaft 8 is welded onto 17, and a stop block 16 is fitted onto the support shaft 8. The upper end of the support shaft 8 is fitted into the support shaft mounting sleeve 27, and the uppermost end of the support shaft 8 is stopped by a limit nut 15. When the hydraulic cylinder 23 extends, the hydraulic cylinder 23 pushes the support shaft bracket 18 downward, and the support shaft bracket 18 drives the support shaft 8 to move downward along the support shaft mounting sleeve 27. When the maximum stroke of the hydraulic cylinder 23 is reached, the stop block 16 is fixed to the upper part of the support shaft 8 by the stop block fixing pin 31, close to the lower end face of the support shaft mounting sleeve 27. The upper end face of the support shaft mounting sleeve 27 is stopped by the limit nut 15, so that the support shaft 8 cannot move, thus supporting the universal caster 20. At this time, the universal caster 20 is in the supporting walking state, and the machine is also in the stage of walking towards the work site.

[0017] Finally, it should be noted that the accompanying drawings of this utility model use a 3-row tiller as an example; the same applies to other models of tillers. The above description is merely the preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
