Description

Technical Field

[0001] This utility model relates to the field of chassis valve equipment, specifically a chassis valve for a cotton harvester. Background Technology

[0002] When picking cotton, cotton harvesters are used to pick the cotton. In order to ensure the normal operation of each component in the cotton harvester, lubrication is an essential part of the maintenance of the cotton harvester. The oil pipes are connected and fixed by valve bodies. After the valve body is installed on the pipeline, it needs to be fixed to the bottom of the chassis. However, the existing valve body on the chassis cannot be shielded and protected.

[0003] According to the patent document CN219035176U, a chassis valve for a three-row cotton harvester includes a valve body with an oil inlet channel and an oil return channel. The valve body also contains several valve components, including a first check valve and a second check valve connected to the rodless chambers of the first and second harvesting cylinders of the cotton harvester, respectively, and a first solenoid valve and a second solenoid valve also connected to the rodless chambers of the first and second harvesting cylinders of the cotton harvester, respectively. In use, oil enters the valve body through the oil inlet channel, and the valve components control some of the hydraulic functions of the three-row cotton harvester. While this solution achieves oil inlet control, the valve body cannot be adjusted in terms of fixing method and point when mounted on the chassis, causing inconvenience during use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a chassis valve for a cotton harvester to solve the problems mentioned in the background. This utility model has a novel structure. In use, after the pipeline is installed on the fixed plate, the fixed plate is limited. The fixed plate moves by rotating the column, and the distance between the fixed plates is adjusted after the arc seat moves, which facilitates the fixed plates to be fixed in different spaces. In addition, the fixed plate can rotate on the rotating column to adjust the position of the fixing point of the fixing hole.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a cotton harvester chassis valve, including a fixed base, a rotating base rotatably mounted on the fixed base, an arc-shaped block welded inside the fixed base, a support base fixed on the arc-shaped block, a fixed plate movably mounted on one end of the support base, an opening on the fixed plate, a threaded hole on the support base, an arc-shaped base movably mounted between the support base and the fixed base, a rotating column fixed to one end of the arc-shaped base, and a fixed plate movably mounted on one end of the rotating column.

[0006] Furthermore, the fixing plate has a slot, and a pipe is movably installed between the slot and the fixing plate.

[0007] Furthermore, the fixing plate has fixing holes, and the inner wall of the slot has mounting holes, with a support mechanism fixed inside the mounting holes.

[0008] Furthermore, a slider is welded to the inner wall of the fixed seat, and a groove is opened on the arc-shaped seat, with the slider movably installed inside the groove.

[0009] Furthermore, a valve body is fixed inside the support base, and a connector is fixed at both ends of the valve body, with the connector in movable contact with one end of the pipeline.

[0010] Furthermore, a support tube is fixed on the inner wall of the fixed plate, and the support tube is movably installed on the joint through a pipe.

[0011] Furthermore, a fixing bolt is rotatably installed between the opening and the threaded hole, and a sealing gasket is installed at one end of the fixing plate and the support base.

[0012] Furthermore, one end of the support mechanism is fixed with a limiting post, and one end of the limiting post moves to contact the pipeline.

[0013] The beneficial effects of this utility model are:

[0014] 1. This type of cotton harvester chassis valve, when in use, limits the fixed plate after the pipeline is installed on the fixed plate. The fixed plate moves the arc-shaped seat through the rotating column. After the arc-shaped seat moves, the distance between the fixed plates is adjusted, which makes it easy to fix the fixed plate in different spaces. In addition, the fixed plate can rotate on the rotating column to adjust the position of the fixing point of the fixing hole.

[0015] 2. In this type of cotton harvester chassis valve, after the fixed plate moves through the rotating column, the slotted plate cooperates with the limiting column to straighten and squeeze the pipe, effectively preventing the pipe from falling downward and contacting the ground, causing wear. In addition, the squeezing of the limiting column facilitates the limiting and fixing of pipes of different diameters.

[0016] 3. The base valve of this cotton harvester has a rotating seat installed on the fixed seat. When the rotating seat comes into contact with the ground, it rotates. The rotation of the rotating seat effectively weakens the impact force, thereby avoiding damage caused by the collision of the internal valve body. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a cotton harvester chassis valve, including a fixed base 1, a rotating base 2 rotatably mounted on the fixed base 1, an arc-shaped block 16 welded inside the fixed base 1, a support base 14 fixed on the arc-shaped block 16, a fixed plate 4 movably mounted on one end of the support base 14, an opening 13 on the fixed plate 4, a threaded hole 15 on the support base 14, an arc-shaped base 3 movably mounted between the support base 14 and the fixed base 1, a rotating column 6 fixed to one end of the arc-shaped base 3, a fixed plate 7 movably mounted on one end of the rotating column 6, a slot 8 on the fixed plate 7, a pipe 10 movably mounted between the slot 8 and the fixed plate 4, and the pipe 10, after being installed inside the slot 8, cooperates with a limiting column 9 for limiting and fixing.

[0024] In this embodiment, the fixing plate 7 has a fixing hole 11, and the inner wall of the slot 8 has an installation hole. A support mechanism 12 is fixed inside the installation hole. The support mechanism 12 is a support spring. The support spring pushes the limiting post 9 to move downward to squeeze and limit the pipe 10. A slider 19 is welded to the inner wall of the fixing seat 1. A sliding groove 18 is opened on the arc-shaped seat 3. The slider 19 is movably installed inside the sliding groove 18. A valve body 17 is fixed inside the support seat 14. Both ends of the valve body 17 are fixed with connectors 20. The connectors 20 are movably in contact with one end of the pipe 10. The valve body 17 is a one-way valve. The one-way valve facilitates the flow of oil and prevents backflow. The one-way valve includes a shaft and a baffle. The baffle realizes unidirectional flow of oil.

[0025] In this embodiment, a support tube 21 is fixed on the inner wall of the fixed plate 4. The support tube 21 is movably installed on the connector 20 through the pipe 10. A fixing bolt 5 is rotatably installed between the opening 13 and the threaded hole 15. A sealing gasket is installed at one end of the fixed plate 4 and the support seat 14. A limit post 9 is fixed at one end of the support mechanism 12. One end of the limit post 9 is movably in contact with the pipe 10. Under the push of the fixing bolt 5, the fixed plate 4 moves towards the support seat 14. The support tube 21 pushes one end of the pipe 10 into the connector 20 for limiting and fixing, so as to prevent the pipe 10 from falling off the connector 20.

[0026] When using this device, the position of the fixing plate 7 is adjusted according to the location of the fixing point. When the fixing plate 7 needs to be fixed vertically and horizontally, the pipe 10 is installed inside the slot 8. After the pipe 10 is installed, the fixing plate 7 is limited. One end of the pipe 10 is installed on the connector 20. The fixing plate 4 is then installed on both ends of the support base 14 by fixing bolts 5. By moving the fixing plate 4, the support pipe 21 pushes the pipe 10 to slide on the connector 20. The connector 20 is fixed with conical teeth, which limit the position of the pipe 10. Under the compression of the support pipe 21, the pipe 10 is fixed at the joint 20 for use. The fixing plate 7 is driven by the rotating column 6 to move the arc-shaped seat 3 inside the fixing seat 1. When the arc-shaped seat 3 moves, the slide groove 18 and the slider 19 cooperate to achieve horizontal movement. After the fixing plate 7 moves through the arc-shaped seat 3, the width of the protection for the pipe 10 is extended, which makes it easier to arrange and fix the pipe 10. After the pipe 10 is installed inside the slot 8, the limiting column 9 is squeezed and limited by the push of the support mechanism 12 to avoid wear caused by the pipe 10 shaking inside the slot 8.
