Description

Technical Field

[0001] This utility model belongs to the field of agricultural tool technology, and in particular relates to a device for measuring and increasing the distance between the telescopic teeth of a harvester. Background Technology

[0002] To maintain a stable and effective feeding function, the distance between the telescopic teeth and the base plate of the harvester's feeding auger needs to be adjusted depending on the crop being harvested. However, due to the location of the height bolt on the telescopic teeth, it is impossible to observe and measure the distance between the telescopic teeth and the base plate while controlling the height bolt under single-person operation. Therefore, it is necessary to adjust the telescopic teeth's extension and retraction while controlling the height bolt, and at the same time measure the distance between the telescopic teeth and the base plate, resulting in a slow adjustment speed for the telescopic teeth.

[0003] This utility model designs a device for measuring and adjusting the spacing between the telescopic teeth of a harvester to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A harvester telescopic tooth spacing measuring and adjustment device includes an outer casing, which is hollow and has openings at the top and sides. A screw cap is installed at the top opening of the outer casing. Inside the outer casing, a lifting base sleeve, a lifting sleeve, and a screw sleeve are installed. The lifting base sleeve is located at the bottom of the outer casing. The upper end of the screw sleeve is threadedly connected to the screw cap. The top of the lifting sleeve passes through the screw sleeve and is inserted into the lifting base sleeve. The lifting sleeve is used to connect with the telescopic teeth of the harvester. A limit plate is installed at the lower end of the screw sleeve. A positioning plate is installed at the upper end of the lifting base sleeve. The limit plate is located above the positioning plate, and the outer ends of the limit plate and the positioning plate extend from the side opening of the outer casing to the outside of the outer casing. A touch-type sensing mechanism is installed at the outer end of the positioning plate below the limit plate. An elastic support component connected to the positioning plate is installed inside the outer casing.

[0006] As a preferred embodiment, the sensing mechanism includes an electrical box located on the outside of the outer casing and connected to the outer end of the positioning plate. A limit switch is installed inside the electrical box, and an audible and visual prompting component electrically connected to the limit switch is installed on the electrical box.

[0007] As a preferred embodiment, the elastic support assembly includes a spring guide rod and a spring. The inner side of the outer sleeve is provided with a guide groove parallel to the central axis of the outer sleeve. The spring guide rod is installed in the guide groove. The upper end of the spring guide rod is connected to the positioning plate. The spring is sleeved on the outer side of the spring guide rod, and the two ends of the spring abut against the positioning plate and the inner wall of the guide groove, respectively.

[0008] As a preferred option, the outer surface of the jacket is engraved with scale values.

[0009] As a preferred embodiment, the upper end of the outer casing is provided with an annular limiting groove, which is perpendicular to the central axis of the outer casing. A set screw is installed on the cap, with one end of the set screw extending into the limiting groove.

[0010] As a preferred option, the bottom of the outer casing is provided with a through hole.

[0011] As a preferred embodiment, the limit plate is located above the limit switch, and the limit plate can contact the limit switch.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. After the device of this utility model is installed on the telescopic tooth of the harvester, under the action of the elastic support component, the outer sleeve is pressed against the bottom plate of the harvester. The positioning plate installed on the lifting base sleeve can directly reflect the extension length of the telescopic tooth. The positioning plate can move with the telescopic tooth's extension and retraction. In conjunction with the height-adjustable limit plate, the positioning plate approaches the limit plate, and the limit plate triggers the sensing mechanism to realize the prompt function when adjusting the telescopic tooth, thereby improving the adjustment speed of the telescopic tooth and solving the problem of needing to adjust and measure at the same time when adjusting the telescopic tooth.

[0015] 2. This utility model adjusts the height of the screw sleeve and the limiting plate by rotating the screw cap, which can more accurately control the position of the limiting plate.

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following embodiments or drawings are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] A device for measuring and adjusting the distance between the telescopic teeth of a harvester, such as... Figures 1 to 5 As shown, the device includes an outer sleeve 1, which is hollow and has openings at the top and sides. A rotating cap 2 is installed at the opening at the top of the outer sleeve 1. Inside the outer sleeve 1, there are a lifting base sleeve 3, a lifting sleeve 4, and a screw sleeve 5. The lifting base sleeve 3 is located at the bottom of the outer sleeve 1. The upper end of the screw sleeve 5 is threadedly connected to the rotating cap 2. The top end of the lifting sleeve 4 passes through the screw sleeve 5 and is inserted into the lifting base sleeve 3. The lifting sleeve 4 is used to connect with the telescopic extraction tooth 6 of the harvester. A limit plate 7 is installed at the lower end of the screw sleeve 5. A positioning plate 8 is installed at the upper end of the lifting base sleeve 3. The limit plate 7 is located above the positioning plate 8, and the outer ends of the limit plate 7 and the positioning plate 8 both extend from the side opening of the outer sleeve 1 to the outside of the outer sleeve 1. A touch-type sensing mechanism is installed at the outer end of the positioning plate 8 below the limit plate 7. An elastic support component connected to the positioning plate 8 is installed inside the outer sleeve 1.

[0024] The lifting base sleeve 3 is slidably connected to the outer sleeve 1, and the lifting sleeve 4 is slidably connected to the lifting base sleeve 3 and the screw sleeve 5. In the initial state, the limiting plate 7 is in contact with the sensing mechanism, and the elastic support component makes the lifting base sleeve 3 abut against the top of the lifting sleeve 4. The other end of the lifting sleeve 4 extends to the outside of the outer sleeve 1.

[0025] After the device is installed on the telescopic tooth 6 of the harvester, under the action of the elastic support component, the outer sleeve 1 abuts against the bottom plate of the harvester. The positioning plate 8 installed on the lifting base sleeve 3 can directly reflect the extension length of the telescopic tooth 6. The positioning plate 8 can move with the telescopic tooth 6. In conjunction with the height-adjustable limit plate 7, the positioning plate 8 approaches the limit plate 7, and the limit plate 7 triggers the sensing mechanism to realize the prompt function when adjusting the telescopic tooth 6. This achieves the purpose of improving the adjustment speed of the telescopic tooth 6 and solving the problem of needing to adjust and measure at the same time when adjusting the telescopic tooth 6.

[0026] Adjusting the height of the threaded sleeve 5 and the limiting plate 7 by rotating the screw cap 2 allows for more precise control of the position of the limiting plate 7. Furthermore, the threaded connection between the threaded sleeve 5 and the screw cap 2 ensures that the limiting plate 7 remains fixed and does not shift when controlling the extension and retraction of the telescopic puller 6, thus providing good stability.

[0027] The sensing mechanism includes an electrical box 9, which is located outside the outer casing 1 and connected to the outer end of the positioning plate 8. A limit switch 10 is installed inside the electrical box 9, and an audible and visual prompt component that is electrically connected to the limit switch 10 is installed on the electrical box 9. In the initial state, the limit plate 7 is in contact with the limit switch 10.

[0028] The outer surface of the jacket 1 is engraved with scale values, which increase from bottom to top.

[0029] like Figure 2 and Figure 3 As shown, the elastic support assembly includes a spring guide rod 11 and a spring 12. The inner side of the outer sleeve 1 is provided with a guide groove parallel to the central axis of the outer sleeve 1. The spring guide rod 11 is installed in the guide groove. The upper end of the spring guide rod 11 is connected to the positioning plate 8. The spring 12 is sleeved on the outer side of the spring guide rod 11. The two ends of the spring 12 abut against the positioning plate 8 and the inner wall of the guide groove, respectively.

[0030] The upper end of the outer sleeve 1 is provided with an annular limiting groove, which is perpendicular to the central axis of the outer sleeve 1. A set screw 13 is installed on the screw cap 2, with one end of the set screw 13 extending into the limiting groove. The screw cap 2 is rotatably connected to the outer sleeve 1. The bottom of the outer sleeve 1 is provided with a through hole 14. When the lifting bottom sleeve 3 moves inside the outer sleeve 1, the through hole 14 is used as a vent.

[0031] like Figure 1 and Figure 4 As shown, the battery 15 is installed inside the electrical box 9. The sound and light prompt component includes an indicator light 16, a start switch 17, and a buzzer 18 installed on the electrical box 9. The limit switch 10, indicator light 16, start switch 17, buzzer 18, and battery 15 are electrically connected. After the start switch 17 is activated, touching the limit switch 10 will turn on the indicator light 16 and the buzzer 18.

[0032] Operating principle:

[0033] First, the equipment is placed on the telescopic tooth 6. The telescopic tooth 6 is inserted into the bottom of the lifting sleeve 4. The harvester's feeding auger is controlled to run, which drives the telescopic tooth 6 to rotate. At this time, the distance between the telescopic tooth 6 and the bottom plate of the harvester changes due to the rotation of the harvester's feeding auger. When the telescopic tooth 6 rotates to the position with the shortest distance from the bottom plate, under the action of the spring 12, the bottom of the outer sleeve 1 abuts against the bottom plate of the harvester. The outer sleeve 1 remains stationary. At this time, the scale of the outer sleeve 1 corresponding to the positioning plate 8 is set as an initial value of the distance between the telescopic tooth 6 and the bottom plate.

[0034] Before adjusting the extension length of the telescopic tooth 6 of the harvester, press the start switch 17 first, then rotate the screw cap 2 to control the screw sleeve 5 to move upward inside the outer sleeve 1. The limit plate 7 moves with the screw sleeve 5 and moves away from the limit switch 10. The length that the telescopic tooth 6 needs to be extended and retracted corresponds to the distance between the limit switch 10 and the limit plate 7. Adjust the position of the limit plate 7 according to the scale value on the outer sleeve 1.

[0035] After the limit plate 7 completes its movement and positioning, adjust the height bolt of the telescopic tooth 6 on the harvester to control the telescopic tooth 6 to continue to retract. Under the action of the spring 12, the lifting base sleeve 3, the positioning plate 8, and the limit switch 10 rise with the telescopic tooth 6 and approach the limit plate 7 until the limit plate 7 contacts the limit switch 10. The indicator light 16 and the buzzer 18 will then give a prompt, and the extension length adjustment of the telescopic tooth 6 will be completed.

[0036] The above are the operating steps for increasing the distance between the telescopic tooth 6 of the harvester and the base plate. If it is necessary to shorten the distance between the telescopic tooth 6 and the base plate, the telescopic tooth 6 needs to be overextended in advance so that the distance between the telescopic tooth 6 and the base plate is shortened to less than the required distance. Then, adjust the telescopic tooth 6 according to the above operating steps.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
