Description

Technical Field

[0001] This utility model relates to the field of magnetic switch technology, specifically to a magnetic switch for cotton harvesters. Background Technology

[0002] A magnetic switch is activated by a magnet; when there is no magnetism, the circuit is open, and it can be used to detect mechanical movement or the state of a circuit. When the magnetic switch is not in operation, the two reeds inside the glass tube are not in contact. If a magnetic material approaches the glass tube, the two reeds will be magnetized and attracted to each other under the influence of the magnetic field, thus connecting the circuit. When the magnetic material disappears, without the influence of external magnetic force, the two reeds will separate due to their own elasticity, breaking the circuit. Magnetic switches are required in the operation of cotton harvesting machines.

[0003] Existing magnetic switches for cotton harvesters are fixed to the cylinder of the harvester with screws to control the cylinder stroke. However, this method is prone to problems because the magnetic switch is susceptible to vibrations during operation and requires regular maintenance. Since the switch is a single unit, the screws need to be removed for disassembly and reassembly, making the process cumbersome and inconvenient for workers. Therefore, there is an urgent need for a new type of magnetic switch for cotton harvesters to solve these problems. Utility Model Content

[0013] By adopting the above technical solution, the slider can drive the positioning rod to move within the adjustment groove.

[0014] Furthermore, the positioning welding is performed on one side wall of the slider, and the positioning rod has a cylindrical structure.

[0015] By adopting the above technical solution, the magnetic switch body can be fixed when the positioning rod is in the positioning hole, and the magnetic switch can be released when the positioning rod is separated from the positioning hole.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] To address the problem that existing magnetic switches for cotton harvesters are fixed to the cylinders with screws to control cylinder stroke, which is susceptible to vibrations during operation and requires regular maintenance, and because of their integrated structure, disassembly and reassembly are cumbersome and inconvenient for workers, this invention addresses this issue by incorporating a telescopic column, spring, slider, positioning rod, and positioning hole. During operation, the positioning rod is fixed within the positioning hole. For disassembly and maintenance, external force is applied to compress the telescopic column and spring, separating the opposing positioning rod from the positioning hole, thus releasing one end of the magnetic switch. The switch can then be pulled out from the other positioning block, simplifying the disassembly process, increasing efficiency, and improving the performance of the magnetic switch.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] like Figures 1-3As shown, a magnetic switch for a cotton harvester in this embodiment includes a base 1. Two sets of adjustment grooves 5 are symmetrically provided on the upper end of the base 1. The adjustment grooves 5 provide installation space for the telescopic column 6. The fixing hole 2 facilitates fixing the base 1 to the cylinder. The telescopic column 6 is installed in the adjustment groove 5. A spring 7 is sleeved on the outside of the telescopic column 6. The magnetic switch body 3 can be limited and fixed by the rebound force of the telescopic column 6 and the spring 7. A slider 9 is fixed on the movable part of the telescopic column 6. A positioning rod 8 is installed on one side wall of the slider 9. The slider 9 can drive the positioning rod 8 to move in the adjustment groove 5. The magnetic switch body 3 is provided on the upper end of the base 1. Positioning holes 10 matching the specifications of the positioning rod 8 are provided on both side walls of the magnetic switch body 3. When the positioning rod 8 is in the positioning hole 10, the magnetic switch body 3 can be fixed. When the positioning rod 8 is separated from the positioning hole 10, the fixing of the magnetic switch can be released.

[0030] like Figures 1-3 As shown, in this embodiment, the adjustment groove 5 is formed on the base 1, and the four corners of the upper end of the base 1 are provided with fixing holes 2. The fixing part of the telescopic column 6 is connected to the inner wall of the adjustment groove 5 by screws. The spring 7 is welded to the outer wall of the telescopic column 6. The slider 9 is fixed to the movable part of the telescopic column 6 by bolts. The specifications of the slider 9 match the specifications of the adjustment groove 5. The slider 9 is positioned and welded to one side wall of the slider 9. The positioning rod 8 is a cylindrical structure. The positioning hole 10 is formed on the magnetic switch body 3. The positioning rod 8 is inserted into the positioning hole 10.

[0031] like Figures 1-3 As shown, in this embodiment, the positioning hole 10 is formed on the magnetic switch body 3, the positioning rod 8 is inserted into the positioning hole 10, and a connecting line 4 is led out from one side wall of the magnetic switch body 3. The connecting line 4 is a signal line and can be connected to an external control device, thereby transmitting the action signal of the magnetic switch body 3 to the control device through the connecting line 4.

[0032] The specific implementation process of this embodiment is as follows: In use, the device is fixed to the cylinder through the fixing hole 2 on the base 1, and then the connecting wire 4 is connected to the external control equipment so that the magnetic switch controls the stroke of the cylinder. During use, the positioning rod 8 is fixed and limited in the positioning hole 10. When the magnetic switch needs to be disassembled and maintained, only an external force is applied to the magnetic switch to compress a set of telescopic columns 6 and spring 7, so that the limiting rods in the opposite direction can be separated from the limiting holes, thereby releasing the fixation of one end of the magnetic switch. Then, the magnetic switch can be pulled out from the other set of positioning to realize the disassembly of the magnetic switch. This effectively simplifies the disassembly steps, improves the disassembly and assembly efficiency, and enhances the performance of the magnetic switch.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention.
