[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 and Figure 2The utility model provides an embodiment of a replaceable tractor voice broadcasting device, including a broadcasting machine 1, which is mainly responsible for the voice broadcasting function. The rear side of the broadcasting machine 1 is fixedly connected to a mounting plate 2, and a mounting groove is provided on the rear side of the mounting plate 2 for stable installation of the broadcasting machine 1. A mounting block 3 is provided on the rear side of the mounting plate 2 for installing the mounting plate 2. A disassembly component is provided on the inner wall of the mounting block 3. The disassembly component includes a card slot 45 for installing the mounting plate 2 to improve the stability of the mounting plate 2. The card slot 45 is provided at the front end of the mounting block 3, and the outer wall of the rear side of the mounting plate 2 slides on the inner wall of the card slot 45. The rear side of the card slot 45 is slidably connected to a limiting plate 41 close to the inner wall of the mounting block 3. The front end of the limiting plate 41 is provided with a convex strip, which can slide into the inner wall of the mounting groove on the mounting plate 2, thereby improving the stability of the mounting plate 2 after installation.

[0034] Reference Figure 2 - Figure 4 The rear side of the limit plate 41 is fixedly connected to a moving block 42, and the movement of the moving block 42 drives the limit plate 41 to move. A slide groove 44 is provided at the top of the moving block 42, and the rear side of the slide groove 44 is set as an inclined surface. The inclined surface of the slide groove 44 is pressed together with the inclined surface of the pressure plate 43 to make the moving block 42 move to the rear side. The mounting block 3 is slidably connected to the pressure plate 43 near the inner wall of the top of the slide groove 44. By pressing the pressure plate 43, the moving block 42 is driven to move to the rear side. The bottom end of the pressure plate 43 is set as an inclined surface, which can cooperate with the inclined surface of the slide groove 44. When the pressure plate 43 is pressed down, A horizontal backward force is generated to move the moving block 42, thereby driving the limit plate 41 to move backward, releasing the limit on the mounting plate 2, and the inclined surface of the bottom end of the pressure plate 43 is in contact with the inclined surface of the inner wall of the slide groove 44. The rear side of the limit plate 41 is elastically connected to the mounting block 3 through the return spring 46. When the limit plate 41 moves, the return spring 46 is squeezed. At the same time, the elastic force of the return spring 46 makes the limit plate 41 stably limit the mounting plate 2, thereby improving its limit stability. Four groups of return springs 46 are provided, and the return springs 46 are initially in a compressed state.

[0035] Reference Figure 2 、 Figure 5 and Figure 6The rear side of the mounting block 3 is rotated to connect the limiting column 5 so that the vertical angle of the mounting block 3 can be changed, and the mounting block 3 is stably supported. An adjustment component is provided on the inner wall of the limiting column 5. The adjustment component includes a limiting ring 1 61. The right outer wall of the limiting ring 1 61 is fixedly connected to the left inner wall of the mounting block 3. The right inner wall of the limiting column 5 is slidably connected to the limiting ring 2 62. The limiting ring 1 61 and the limiting ring 2 62 are provided with teeth and can be inserted into each other, thereby limiting the angular position of the mounting block 3. The right side of the limiting ring 2 62 is inserted On the left side of the limit ring 1 61, the limit ring 2 62 is fixedly connected to a pull rod 63, and the pull rod 63 is set to a U shape, with both ends fixed on the limit ring 2 62. By pulling the pull rod 63, the limit ring 2 62 is driven to move, so that the limit ring 2 62 slides out from the outer wall of the limit ring 1 61, and the limitation on the limit ring 1 61 is released. The limit ring 2 62 and the limit column 5 are elastically connected through the compression spring 1 64. The elastic force of the compression spring 1 64 makes the limit ring 2 62 stably limit the limit ring 1 61, and at the same time drives the pull rod 63 to reset.

[0036] Reference Figure 2 and Figure 7 The bottom end of the limit column 5 is fixedly connected to the turntable 7 for stably supporting the limit column 5. The outer wall of the bottom end of the turntable 7 is rotatably connected to the bottom plate 8 and is fixedly installed on the tractor by bolts to fix the device. The inner wall of the turntable 7 is provided with a rotating assembly, which includes a sliding post 91. The outer wall of the sliding post 91 slides on the inner wall of the turntable 7 to provide support for the limiting bead 93. The front end of the sliding post 91 is fixedly connected to the limiting bead 93. The limiting bead 93 slides in the limiting groove to limit the rotation of the turntable 7. The sliding post 91 and the turntable 7 are elastically connected by a compression spring 2 92. The elastic force of the compression spring 2 92 causes the limiting bead 93 to slide into the limiting groove to limit the rotation of the turntable 7, so that the direction of the broadcaster 1 can be quickly adjusted. The inner wall of the bottom plate 8 is provided with a limiting groove near the limiting bead 93, and multiple groups are provided to enable the turntable 7 to be rotatable and adjusted in multiple directions. The outer wall of the limiting bead 93 slides on the inner wall of the limiting groove.

[0037] Working principle: During use, when the broadcaster 1 needs to be maintained or replaced, first press the pressure plate 43 to move the pressure plate 43 downward, and squeeze the inclined surface at the bottom end of the pressure plate 43 and the inner wall of the slide groove 44 to make the moving block 42 move backward. The moving block 42 drives the limiting plate 41 to slide on the inner wall of the mounting block 3, and at the same time squeezes and compresses multiple sets of return springs 46 to release the limiting plate 41 from the mounting plate 2. At this time, the broadcaster 1 can be pulled to one side to drive the mounting plate 2 to slide out from the inner wall of the slot 45, thus completing the disassembly of the broadcaster 1. At this time, the broadcaster 1 can be maintained or replaced with a new one.

[0038] When it is necessary to adjust the vertical angle of the broadcaster 1, pull the pull rod 63, and the pull rod 63 drives the limit ring 2 62 to slide on the inner wall of the limit column 5, and at the same time compresses the two sets of compression springs 1 64, so that the limit ring 2 62 slides out from the limit ring 1 61, releasing the limit on the mounting block 3. At this time, the broadcaster 1 drives the mounting block 3 to rotate on the middle outer wall of the limit column 5 to adjust the angle of the broadcaster 1. When the adjustment is completed, release the pull rod 63, and the elastic force of the two sets of compression springs 1 64 causes the limit ring 2 62 to be inserted into the limit ring 1 61, thereby limiting the mounting block 3 and thus limiting the broadcaster 1.

[0039] When the direction of the broadcaster 1 needs to be adjusted, the turntable 7 is driven to rotate on the inner wall of the base plate 8 by rotating the limit column 5. While the turntable 7 rotates, the limit bead 93 slides out of the limit groove on the base plate 8, so that the limit bead 93 drives the slide column 91 to slide on the inner wall of the turntable 7, and at the same time squeezes the compression spring 2 92. The elastic force of multiple groups of compression springs 2 92 causes the limit bead 93 to slide into the limit groove, limiting the turntable 7, so that the direction of the broadcaster 1 can be quickly adjusted.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
