Description

Technical Field

[0001] The utility model relates to the technical field of film raking machines, in particular to a residual film raking machine which is convenient to clean. Background Technique

[0002] Film mulching cultivation is the main cultivation method in agricultural production. However, the residual plastic films every year also bring disadvantages to agricultural production. For example, the residual plastic films reduce the water infiltration amount, lower the soil water content, affect the soil air permeability, and ultimately reduce the soil fertility level. It also causes "visual pollution". At the same time, the residual films are mixed with crop straws and forage grasses. After being accidentally eaten by herbivores such as cattle and sheep, they will block the esophagus, affect digestion and absorption, and may cause suffocation and death of livestock in severe cases.

[0003] At present, the main method for recycling residual plastic films is to use film raking machines. The existing residual film raking machines can collect and process the residual plastic films in the planting land. However, after running for a long time, a large amount of plastic films are wound around the film raking teeth, which affects the subsequent raking of plastic films. Usually, it is necessary to manually remove and clean them at the end of the field. Due to the large number of raking teeth, the entire cleaning process has low efficiency and high labor intensity. Content of the Utility Model

[0004] The purpose of the utility model is to provide a residual film raking machine which is convenient to clean, so as to solve the problems of high labor intensity and low efficiency in the process of manually removing residual films.

[0005] The utility model is implemented by the following technical solutions: A residual film raking machine which is convenient to clean, which includes a bracket, a towing frame, a film raking assembly, and a residual film cutting device. The towing frame is fixed at the top of the bracket, and at least one group of the film raking assemblies perpendicular to the traveling direction is fixed at the bottom of the bracket. The film raking assembly includes a plurality of parallel film raking teeth, and the residual film cutting device is slidably arranged on the film raking teeth. The residual film cutting device is detachably connected to the bracket through a connecting piece.

[0006] Further, the residual film cutting device includes an annular sliding sleeve, a cutting knife, and a reinforcing plate. The annular sliding sleeve is slidably sleeved on the film raking teeth. The inner diameter of the annular sliding sleeve matches the diameter of the film raking teeth. A plurality of the cutting knives are fixed on the annular wall between the outer circle and the inner circle of the annular sliding sleeve. The cutting knives are arranged along the circumferential direction of the annular sliding sleeve, and the cutting knives are inclined towards the axis of the annular sliding sleeve. The reinforcing plate is fixed between adjacent two cutting knives.

[0007] Further, the cutting knife includes a knife body and a knife tip. One end of the knife body is fixedly connected to the annular sliding sleeve, and the other end of the knife body is fixedly connected to the knife tip.

[0008] Furthermore, the blade body is a triangular prism structure, the blade tip is a triangular pyramid structure, the side edge of the blade tip is a first cutting edge, and the side edge of the blade body is a second cutting edge.

[0009] Furthermore, the connecting member includes a fixed plate, a bent rod, a hook, and a hanging ring. At least one of the annular sliding sleeves is fixed to the top of the fixed plate, the bent rod is fixed to the top of the fixed plate, the end of the bent rod is rotatably connected to the hook, and a hanging ring matching the hook is fixed on the bracket, and the hook and the hanging ring are detachably connected.

[0010] Furthermore, a root planing assembly is fixed to the bottom end of the bracket, the root planing assembly is arranged in parallel with the membrane holding assembly, and the root planing assembly includes a plurality of parallelly arranged root planers.

[0011] Furthermore, the root planing assembly and the membrane holding assembly are fixedly connected to the bracket in sequence along the traveling direction.

[0012] Furthermore, traveling wheels are respectively fixed on both sides of the bracket.

[0013] The utility model has the advantages that when residual film is wound on the film-holding teeth, the machine moves to the field, and the workers cut off the residual film on the film-holding teeth through the residual film cutting device, which is simple to operate and has low labor intensity;

[0014] The cutting knife is arranged obliquely on the residual film cutting device, which has a guiding function and cuts off the wound residual film in the process of stretching it out. The cutting efficiency is higher than that in a loose state. A reinforcing plate is fixed between two adjacent cutting knives. The reinforcing plate can ensure the stability and firmness of the cutting knife. At the same time, under the action of the connecting part, the fixed plate is used to drive multiple annular sliding sleeves to move, and the cleaning work of the residual film of multiple film-holding teeth can be completed at one time, which saves the labor intensity of workers and improves work efficiency.
