Abstract
Description
Technical Field
[0001] The utility model 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 has gradually become the mainstream method in the market.
[0003] The current belt-type spike-tooth residual film pickup mechanism consists of three pickup rollers forming a triangle. A belt with pickup teeth is wound around the three pickup rollers, and the belt rotates to pick up residual film. Before picking up residual film, the height of the lower pickup roller above the ground must be adjusted. During operation, the machine cannot contour the film while working, and can only operate at a fixed height. This affects the pickup of residual film when the ground is uneven. Furthermore, if a groove appears in the direction of travel of the residual film pickup machine, even if the pickup mechanism contours the entire structure, it cannot pick up the residual film in the groove in the direction of travel, and the pickup effect will not be as expected. The residual film in the groove cannot be picked up by the pickup teeth, and can only be picked up by hooking the film on both sides of the groove. At this time, the film may be pulled and torn, reducing the residual film pickup effect.
[0004] The present application proposes a full-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 utility model is to provide a full-floating profiling residual film picking mechanism with simple structure, good picking effect and profiling function.
[0006] The picking mechanism includes a frame, on which are provided a picking roller A, a picking roller B and a picking roller C. The three picking rollers are in an inverted triangle shape, and a stripping roller is provided on the rear picking roller. The stripping roller is provided with a gap, and the picking roller B and the picking roller C are composed of a plurality of independent picking wheels of the picking roller B and the picking wheels of the picking roller C. A picking belt is wound around the three picking rollers, and the picking belt is provided with picking teeth. The picking belt can pass through the gaps between the stripping rollers and can be retracted into the stripping roller after passing through the picking teeth of the stripping roller. The picking wheel is arranged at one end of a swing arm, and the other end of the swing arm is hinged to the 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 wheel of the picking roller B to float up and down within a certain range with the swing arm as the axis, and the profiling mechanism limits the picking wheel of the picking roller C 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 and pick up on a plane. The film in the groove pressed by the wheels of the tractor or cotton picker cannot be picked up. This problem exists after the cotton field or corn field is harvested. This problem can be solved by studying this technical solution.
[0008] To achieve the above objectives, the present invention provides the following technical solutions:
[0009] A fully floating, contoured residual film picking mechanism comprises a frame, wherein the frame is provided with 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 provided at the bottom, and the picking rollers A and B are provided at the top.
[0010] 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 wheels of the pick-up roller B, and the pick-up roller C (16) includes a plurality of pick-up wheels of the pick-up roller C.
[0011] The pick-up wheel of the upper single pick-up roller B corresponds to the pick-up wheel of the lower single pick-up roller C.
[0012] 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 provided on the pickup wheel of the pickup roller B and the pickup wheel of the pickup roller C that correspond to each other.
[0013] The picking belt (20) is provided with a picking tooth (21), and the picking belt (20) can pass through the gap of the demolding roller (2), and the picking tooth (21) passing through the demolding roller (2) can be retracted into the demolding roller (2). The picking wheel is provided at one end of the swing arm, and the other end of the swing arm is hinged on the bracket.
[0014] A profiling mechanism is provided between the middle part of the swing arm and the limit frame, which limits the picking wheel of the picking roller B to float up and down within a certain range with the swing arm as the axis, and the profiling mechanism limits the picking wheel of the picking roller C to float up and down within a certain range with the swing arm as the axis.
[0015] As an improvement, the swing arms are provided with a plurality of them, a single or two adjacent picking wheels are provided on one swing arm, and each swing arm is provided with an independent profiling mechanism.
[0016] In actual use: When the ground is uneven, the pickup wheel of the lower pickup roller C can drive the upper front pickup roller B to perform profiling operation under the action of the profiling mechanism, thereby improving the picking up effect of the residual film.
[0017] When the pickup wheel of the lower pickup roller C moves upward, the pickup wheel of the upper pickup roller B is pushed upward under the action of the profiling mechanism, so that the pickup belt is always under tension.
[0018] 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 a single set of picking wheels (single swing arm) has a contoured structure, the picking wheels of the picking roller C can enter the groove to pick up the ground film, and there will be no situation where the residual film in the groove cannot 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 entering the groove to pick up, the phenomenon of pulling and tearing the ground film is avoided, thereby improving the residual film picking effect.
[0019] When a single set of picking wheels is provided with a swing arm, each picking belt (20) can be individually contoured. The picking wheels at the groove enter the groove under the action of the contouring mechanism, while the picking wheels on both sides of the groove can continue to pick up outside the groove, thereby improving the overall picking effect of the ground film.

[0031] As an improvement, a pull rod (9) is provided between the picking wheel of the picking roller B and the picking wheel of the picking roller C supporting the same picking 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 picking wheel of the picking roller B and the swing arm on the picking wheel of the picking roller C form a connecting rod mechanism.
[0032] 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 by the pull rod, and the overall rigidity is better.
[0033] The two ends of the pull rod (9) can be hinged to the swing arm A (7) and the swing arm B (19) respectively, or can be hinged to the axes of the picking wheels of the picking roller B and the picking wheels of the picking roller C.
[0034] The pull rods (9) are provided in multiple groups, and the picking wheels of each picking belt or the picking wheels of adjacent picking belts are each provided with a pull rod (9) individually.
