Abstract
Description
Technical Field
[0001] This utility model is a suspension rod limiting device for a silage harvester. Background Technology
[0002] Currently, most silage harvester suspension rods used in China are directly fixed, unable to adapt to complex environments, resulting in relatively simple and inflexible designs. Furthermore, some manufacturers produce suspension rod adjustment devices, but the adjustment range is too small, lacking adaptability, and the guide rod's extension and retraction distance is insufficient. Additionally, they experience severe wear and tear under high-intensity working conditions. Utility Model Content:
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a suspension rod limiting device for silage harvesters.
[0004] A suspension rod limiting device for a silage harvester includes a suspension rod and a column. One end of the suspension rod is provided with a sliding sleeve, and the surface of the sliding sleeve is provided with a clearance hole. A mounting box is provided at the clearance hole, and a positioning post is movably inserted into the mounting box. The mounting box has openings on both sides that correspond to the clearance hole, and a cavity is provided inside. The column is provided with a plurality of limiting holes spaced apart along its height direction, and the limiting holes are used for the limiting post to pass through.
[0005] Furthermore, the opening on the mounting box near the clearance hole is the first opening, and the opening away from the clearance hole is the second opening. One end of the limiting post is provided with a head, the size of which is smaller than the first opening and larger than the second opening.
[0006] Furthermore, a spring is sleeved on the outer wall of the limiting post, and the two ends of the spring abut against the head of the limiting post and the inner wall of the second opening of the mounting box, respectively.
[0007] Furthermore, a handle is provided at the other end of the limiting post.
[0008] Furthermore, the limiting post is a bolt, and the bottom of the bolt is provided with a limiting nut. The end face of the limiting nut near the second opening is a bevel, and the outer bottom face of the mounting box near the limiting nut is a bevel.
[0009] Furthermore, the handle is a ring structure with a connecting sleeve in its middle section, which is threaded to the outer side of the bottom of the bolt.
[0010] Beneficial effects: Compared with the prior art, the present invention has the following advantages:
[0011] The design of the sliding sleeve and clearance hole allows the suspension rod to be flexibly adjusted on the column. At the same time, the combination of the positioning post and the limiting hole ensures the stability of the suspension rod after it is adjusted to the desired position, preventing displacement during use.
[0012] The mounting box design allows the positioning pin to easily insert and exit the limiting hole, thereby locking and unlocking the suspension rod position. Especially when the limiting pin is designed as a bolt, its position can be easily adjusted by rotating the bolt, making operation simple and quick.
[0013] The design of the limiting post head size (smaller than the first opening, larger than the second opening), along with the addition of a spring, ensures that the limiting post remains stably within the mounting box when no external force is applied, preventing accidental detachment. This design also increases the safety and reliability of the device.
[0014] The handle design allows users to easily operate the limit post, especially when the suspension rod position needs to be adjusted frequently. This design greatly reduces the difficulty and cost of maintenance.
[0015] The limiting post is designed as a bolt, equipped with a limiting nut and a beveled structure. After installation, it generates a bending moment on the bolt, enhancing its anti-loosening ability and tightening effect. This not only increases the stability of the device but also improves its adaptability and practicality. Furthermore, the design of the ring handle and connecting sleeve reflects the device's innovative attention to detail. Attached Figure Description

[0021] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0022] like Figure 1-4 As shown, the components are: 1. suspension rod; 2. column; 3. sliding sleeve; 4. mounting box; 5. limit nut; 6. connecting sleeve; 7. handle; 8. limit post; 9. spring; 10. head.
[0023] A suspension rod limiting device for a silage harvester includes a suspension rod 1 and a column 2. One end of the suspension rod 1 is provided with a sliding sleeve 3. The surface of the sliding sleeve 3 is provided with a clearance hole. A mounting box 4 is provided at the clearance hole. A positioning post is movably inserted into the mounting box 4. The mounting box 4 has openings on both sides that correspond to the clearance hole. It has a cavity inside. The column 2 is provided with a plurality of limiting holes spaced apart along its height direction. The limiting holes are used for the limiting post 8 to pass through.
[0024] In this example, the opening on the mounting box 4 near the clearance hole is the first opening, and the opening away from the clearance hole is the second opening. One end of the limiting post 8 is provided with a head 10, the size of which is smaller than the first opening and larger than the second opening.
[0025] In this example, a spring 9 is sleeved on the outer wall of the limiting post 8, and the two ends of the spring 9 abut against the head 10 of the limiting post 8 and the inner wall of the second opening of the mounting box 4, respectively.
[0026] In this example, the other end of the limiting post 8 is provided with a handle 7.
[0027] In this example, the limiting post 8 is a bolt, and the bottom of the bolt is provided with a limiting nut 5. The end face of the limiting nut 5 near the second opening is a slope, and the outer bottom face of the mounting box 4 near the limiting nut 5 is a slope.
[0028] In this example, the handle 7 is a ring structure, with a connecting sleeve 6 in the middle section, and the connecting sleeve 6 is threadedly connected to the outer side of the bottom of the bolt.
[0029] Instructions for use: Under normal conditions, the limiting posts (i.e., bolts) are sequentially inserted into the mounting box and the column, which limit the position of the suspension rod and prevent the limiting posts from detaching from the column by the spring. When it is necessary to adjust the position of the suspension rod, pull the handle to move the limiting posts away from the column, adjust the position of the suspension rod up and down, release the handle, and under the action of the spring, the limiting posts will insert into the limiting holes of the column, limiting the suspension rod again and keeping the suspension rod and the column relatively stationary.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
