Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery, and in particular relates to a full-floating contour-matching residual film picking-up mechanism for picking up residual film. Background Art

[0002] The residual film recycling machine includes a picking mechanism and a packaging mechanism. The picking mechanism is divided into spring tooth picking, clamping picking, belt spike tooth picking, etc. Belt spike tooth picking is gradually becoming the mainstream method in the market.

[0003] The current belt spike-tooth residual film picking mechanism is formed by three picking rollers in a triangle, on which a belt is wound, and the belt has picking teeth. The residual film is picked up by the rotation of the belt. Before the residual film picking operation, the height of the lower picking roller from the ground is adjusted. During work, it is impossible to copy the shape while working, and it can only work at a fixed height. When the ground is uneven, it affects the picking of residual film. At the same time, when there is a groove in the walking direction of the residual film picking machine, even if the picking mechanism is copied as a whole, it cannot pick up the residual film in the walking direction of the groove, and the picking effect cannot reach the expected result. The residual film in the groove cannot be hooked up by the picking teeth, and can only be picked up by hooking the ground film on both sides of the groove. At this time, the ground film may be pulled and torn off, reducing the residual film picking effect.

[0004] The present application proposes a fully floating profiling residual film picking mechanism with a simple structure, good picking effect and profiling function. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a full-floating profiling residual film picking-up mechanism with simple structure, good picking-up effect and profiling function.

[0006] The picking mechanism includes a frame, on which a picking roller A, a picking roller B and a picking roller C are provided. The three picking rollers are in an inverted triangle shape. A stripping roller is provided on the rear picking roller, and a gap is provided on the stripping roller. The picking roller B and the picking roller C are both composed of a plurality of independent picking roller B picking wheels and picking roller C picking wheels. Picking belts are wound around the three picking rollers, and the picking belts are provided with picking teeth. The picking belts can pass through the gaps between the stripping rollers, and the picking teeth that pass through the stripping rollers can be retracted into the stripping rollers. The picking wheels are arranged at one end of a swing arm, and the other end of the swing arm is hinged on a bracket. A profiling mechanism is provided between the middle part of the swing arm and the limit frame, and the profiling mechanism limits the picking roller B picking wheel to float up and down within a certain range with the swing arm as the axis, and the profiling mechanism limits the picking roller C picking wheel to float up and down within a certain range with the swing arm as the axis.

[0007] This solution solves the problem that the picking roller of the residual film recycling machine on the market is fixed with a through shaft, and all the picking teeth are on a through shaft, picking up on a plane. The film in the groove pressed by the wheels of a tractor or a cotton picker cannot be picked up. This problem exists after the cotton field or the corn field is harvested. This problem can be solved by studying this technical solution.

[0008] To achieve the above object, the present invention provides the following technical solutions: A fully floating contour residual film picking mechanism comprises a frame, on which is provided an inverted triangle picking structure formed by three picking rollers, namely a picking roller A (1), a picking roller B (8) and a picking roller C (16), a film stripping roller (2) is provided on the rear picking roller, a gap is provided on the film stripping roller (2), the picking roller C is arranged at the bottom, and the picking roller A and the picking roller B are arranged at the top. The pick-up roller B (8) and the pick-up roller C (16) are both composed of a plurality of independent pick-up wheels, that is, the pick-up roller B (8) includes a plurality of pick-up roller B pick-up wheels, and the pick-up roller C (16) includes a plurality of pick-up roller C pick-up wheels. The upper single pick-up roller B pick-up wheel and the lower single pick-up roller C pick-up wheel correspond one to one. A pickup belt (20) is wound around the three pickup rollers, that is, the pickup belt (20) is wound around the pickup wheel of the pickup roller B, the pickup wheel of the pickup roller C and the pickup roller A, and a pickup belt is respectively arranged on the pickup wheel of the pickup roller B and the pickup wheel of the pickup roller C that correspond to each other. The picking belt (20) is provided with picking teeth (21), and the picking belt (20) can pass through the gap of the demolding roller (2), and the picking teeth (21) can be retracted into the demolding roller (2) after passing through the demolding roller (2). The picking wheel is arranged at one end of the swing arm, and the other end of the swing arm is hinged on the bracket. A profiling mechanism is provided between the middle part of the swing arm and the limiting frame, and the profiling mechanism limits the picking roller B picking wheel to float up and down within a certain range with the swing arm as the axis, and the profiling mechanism limits the picking roller C picking wheel to float up and down within a certain range with the swing arm as the axis.

[0009] As an improvement, the swing arms are provided with a plurality of them, a single or two adjacent picking wheels are arranged on one swing arm, and each swing arm is provided with an independent profiling mechanism.

[0010] In actual use: When the ground is uneven, the pickup roller C at the bottom can drive the pickup roller B at the front to perform the profiling operation under the action of the profiling mechanism, thereby improving the picking effect of the residual film.

[0011] When the pickup roller C at the bottom moves upward, the pickup roller B at the top is pushed upward by the contouring mechanism, so that the pickup belt is always under tension.

[0012] The details are as follows: when grooves appear on the ground in the walking direction, the picking wheels supporting each picking belt are set on the same set of swing arms, or the picking wheels of several adjacent picking belts share a set of swing arms. Because of the contoured structure, the picking roller C can enter the groove to hook and pick up the ground film, and the residual film in the groove will not be unable to be hooked up by the picking teeth, avoiding the traditional picking mechanism that can only pick up the ground film on both sides of the groove by hooking. By entering the groove to pick up, the phenomenon of pulling and tearing the ground film can be avoided, thereby improving the residual film picking effect.

[0013] When a single set of picking wheels is provided with a swing arm, each picking belt (20) can be individually contoured, and the picking wheels at the groove enter the groove under the action of the contouring mechanism, while the picking wheels at both sides of the groove can continue to pick up outside the groove, thereby improving the overall picking effect of the ground film.

[0015] In actual use, the upper pickup roller B pickup wheel and the lower pickup roller C pickup wheel can float up and down under the action of the swing arm A (7) and the swing arm B (19), thereby realizing contour picking by a single set of pickup belts.

[0016] As an improvement, the contouring mechanism includes a limit rod and a spring, one end of the limit rod is connected to the swing arm, and the other end passes through the limit frame, and a limit block is provided at the end of the limit rod passing through the limit frame.

[0019] As an improvement, a pull rod (9) is provided between the pick-up roller B pick-up wheel and the pick-up roller C pick-up wheel supporting the same pick-up belt, or a pull rod (9) is provided between the upper and lower corresponding swing arms, and the pull rod (9), the swing arm on the pick-up roller B pick-up wheel and the swing arm on the pick-up roller C pick-up wheel form a connecting rod mechanism.

[0020] In actual use: by setting the pull rod, better rigidity can be achieved, that is, when the pick-up roller C and the pick-up roller B float up and down, they are formed into a whole through the pull rod, and the overall rigidity is better.

[0021] The two ends of the pull rod (9) can be respectively hinged on the swing arm A (7) and the swing arm B (19), or can be hinged on the shafts of the pick-up roller B and the pick-up roller C.

[0022] The pull rods (9) are provided in multiple groups, and the pick-up wheels of each pick-up belt or the pick-up wheels of adjacent pick-up belts are individually provided with pull rods (9).

[0023] As an improvement, the pull rod (9) is provided with an adjusting screw rod (13) capable of adjusting the length of the pull rod (9).
