AI Technical Summary
Existing pickup belts are prone to damage or missed pickups when encountering hard objects due to their toothed and needle-like structures, and cannot accommodate pickup depth adjustment.
A belt tensioning mechanism for picking up belts was designed. By adjusting the rotation of the adjusting sleeve and adjusting screw, the center distance between the fixed shaft and the fixed pin shaft is adjusted, thereby achieving height adjustment of the belt tensioning shaft tube and avoiding damage to the picking belt.
It achieves the combined use of both toothed and needle-type pickup belts, ensuring the stability of pickup depth and preventing damage to the pickup belt.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to agricultural machinery technical field, concretely relates to a pick up belt tensioning mechanism. BACKGROUND
[0002] In the pick up mechanism of the film residue removing machine, the pick up belt is currently divided into the elastic tooth type and the needle type; in use, the pick up mechanism of the elastic tooth structure can automatically adjust the depth and will not cause the elastic tooth damage when encountering hard objects such as stones; the needle type structure is hard connected and is easy to cause the damage of the needle part and the leakage of picking when encountering hard objects such as stones; it is not possible to take into account, and therefore needs to be improved. SUMMARY
[0003] The utility model discloses to the defects and the insufficient of prior art, provide a pick up belt tensioning mechanism.
[0004] In order to achieve the above object, the utility model adopts the technical scheme, a pick up belt tensioning mechanism, including the frame, its innovation point lies in: the frame is connected through the bolt fixed adjustment board, the fixed pin shaft is arranged on the adjustment board, one end of the fixed pin shaft is connected with the belt tensioning shaft pipe, the other end of the fixed pin shaft is externally sleeved with the adjusting screw rod, the outside of the adjusting screw rod is sleeved with the spring, the lower end of the adjusting screw rod is located to the spring, the top of the adjusting screw rod is provided with the adjusting sleeve, the adjusting sleeve is located in the spring, the adjusting sleeve is provided with the fixed shaft, and the fixed shaft is arranged on the frame.
[0005] Further, when the adjusting sleeve rotates, the adjusting screw rod is driven to ascend and descend.
[0006] After adopting the above structure, the utility model has the beneficial effects that:
[0007] The utility model adjusts the center distance of the fixed shaft and the fixed pin shaft by rotating the adjusting sleeve, that is, adjusts the height of the adjusting screw rod from the ground, realizes the height adjustment of the belt tensioning shaft pipe, and meets the use requirements of the elastic tooth type pick up belt and the needle type pick up belt. BRIEF DESCRIPTION OF DRAWINGS
[0008] Figure 1 It is the structural schematic diagram of the utility model.
[0009] Mark explanation:
[0010] 1 frame, 2 adjustment board, 3 fixed pin shaft, 4 belt tensioning shaft pipe, 5 adjusting screw rod, 6 spring, 7 adjusting sleeve, 8 fixed shaft. DETAILED DESCRIPTION
[0011] The utility model will be further described below in combination with the drawings.
[0012] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.
[0013] Referring to Figure 1 A kind of pick-up belt tensioning mechanism, including rack 1, rack 1 is connected by bolt adjustment plate 2, fixed pin shaft 3 is provided on adjustment plate 2, one end of fixed pin shaft 3 is connected with belt tensioning shaft pipe 4, its other end is externally connected with adjusting screw 5, spring 6 is externally connected with adjusting screw 5, the lower end of adjusting screw 5 is limited to spring 6, adjusting sleeve 7 is arranged at the top of adjusting screw 5, adjusting sleeve 7 is located inside spring 6, fixed shaft 8 is arranged through adjusting sleeve 7, and fixed shaft 8 is arranged on rack 1.Specifically, belt tensioning shaft pipe 4, adjustment plate 2 and fixed pin shaft 3 are assembled into components, one end is fixed on rack 1 by bolt, the lower end of adjusting screw 5 is sleeved on fixed pin shaft 3, spring 6 is sleeved on adjusting screw 5, adjusting sleeve 7 is arranged through the center hole of fixed shaft 8, is sleeved in spring 6, is connected with adjusting screw 5, and fixed shaft 8 is on rack 1;After assembly, by the rotation of adjusting sleeve 7, the center distance of fixed shaft 8 and fixed pin shaft 3 is adjusted to use state;By adjusting, spring 6 generates tensioning force by compression;When working, belt tensioning shaft sleeve 4 contacts field ground, pick-up belt works, in the use process, when encountering stone and other hard objects, adjusting sleeve 7 rotates, adjusting screw 5 rises, and belt tensioning shaft pipe 4 rises to prevent pick-up belt from being damaged by needle. If working state, the field ground is relatively soft, belt tensioning shaft pipe 4 is lowered by the tensioning force of spring 6, to ensure the pick-up depth of pick-up belt.
[0014] In the embodiment, when adjusting sleeve 7 rotates, adjusting screw 5 is driven to ascend and descend, that is, the height of adjusting screw 5 from the ground is adjusted, to realize the height adjustment of belt tensioning shaft pipe 4.
[0015] The above description is only used to explain the technical scheme of the utility model and not to limit the utility model. Other modifications or equivalent replacements to the technical scheme of the utility model made by those skilled in the art should be covered in the scope of claims of the utility model.
