Description

Technical Field

[0001] This utility model relates to the field of agricultural residual film recycling technology, and more specifically to a toothed belt for the impurity removal mechanism of a residual film recycling machine. Background Technology

[0002] In industry, belts, also known as transmission belts, are used to transmit the power generated by the rotation of a motor or engine in a prime mover to mechanical equipment via pulleys and a rubber belt. Their greatest advantages are the ability to freely change speeds, transmit power over long and short distances, their simple structure, and easy replacement. Therefore, transmission belts are found in everything from primitive machinery to modern automated equipment, and the product has undergone numerous evolutions, with the technology becoming increasingly mature.

[0003] Belts are also commonly used in residual film recycling machines. Existing residual film recycling machines require belts for both the picking mechanism and the waste removal, with varying forms and functions. For example, Chinese Patent CN 213368520 U discloses a residual film recycling mechanism and device, and a straw crushing residual film recycling and separation device. This device improves the separation of film and waste by setting sieve holes on the conveyor belt and using a vibration mechanism; it also improves the residual film recovery rate by setting flexible scrapers on the conveyor belt and using film-picking teeth. However, this type of transmission belt has a complex structure and high production costs.

[0004] Therefore, there is an urgent need for a toothed belt for the impurity removal mechanism of a residual film recycling machine. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a toothed belt for the impurity removal mechanism of a residual film recycling machine, so as to solve the problems in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0007] A toothed belt is used in the impurity removal mechanism of the residual film recycling machine. It is used between two rotating rollers of the impurity removal mechanism and includes a ring-shaped belt. The belt includes an inner layer and an outer layer laid together. The outer layer of the belt is evenly provided with a number of toothed prongs with their tips facing outwards and perpendicular to the belt. The bottom of each toothed prong is connected to a mounting base, and the toothed prong and the mounting base are integrally formed. The mounting base is connected to the belt by a number of bolts, and the nuts of the bolts are located between the outer layer and the inner layer of the belt. The width of the mounting base is smaller than the width of the belt, and the width of the toothed prong is smaller than the width of the mounting base.

[0008] To further optimize the technical solution, the belt is made of composite rubber material.

[0009] To further optimize the technical solution, the nail teeth are made of wear-resistant metal.

[0010] To further optimize the technical solution, the nail tooth includes an upper part and a lower part. The upper part of the nail tooth has an isosceles trapezoidal cross section in the left-right direction, a rectangular cross section in the front-back direction, and a rectangular cross section that gradually increases in size from top to bottom. The lower part of the nail tooth has an isosceles trapezoidal cross section in the left-right direction with the waist curving inward, and both the front-back direction cross section and the cross section are rectangular.

[0011] To further optimize the technical solution, the mounting base includes an intermediate plate connected to the nail teeth, with connecting plates on the left and right sides of the intermediate plate; the two connecting plates are symmetrically arranged, and bolt holes are provided on the connecting plates; the intermediate plate is a horizontal plate, the lower end surfaces of the two connecting plates are horizontal, the upper end surfaces are inclined, and the upper end surface of the intermediate plate and the upper end surfaces of the two connecting plates form an upward convex structure.

[0012] Due to the adoption of the above technical solutions, the technical progress achieved by this utility model is as follows.

[0013] This utility model provides a toothed belt for the impurity removal mechanism of a residual film recycling machine. Through a unique design of the tooth shape, the film-picking efficiency of the teeth is improved, and the wear rate of the teeth during operation is reduced. By setting a mounting base and connecting the mounting base to the belt with bolts, the stability of the connection between the teeth and the belt is increased. By concealing the bolts and nuts inside the belt, wear on the rotating rollers caused by the bolts and nuts during belt operation is avoided. This utility model has the advantages of high film-picking efficiency, good impurity removal effect, simple structure, low cost, and long service life. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] The residual film recycling machine uses a toothed belt for its waste removal mechanism, which is fitted between the two rotating rollers of the waste removal mechanism. Figures 1 to 4 As shown, it includes a belt 1, spike teeth 2, and mounting base 3. Mounting base 3 includes bolt holes 31, a middle plate 32, and a connecting plate 33. Belt 1 includes an outer layer 11 and an inner layer 12.

[0018] The belt 1 is a ring-shaped belt made of composite rubber. The belt 1 includes an inner layer 12 and an outer layer 11, which are laid together by injection molding.

[0019] The outer layer 11 of the belt 1 is evenly perforated with a plurality of spikes 2 with their tips pointing outwards from the belt 1, and the spikes 2 are perpendicular to the belt 1. The spikes 2 are made of wear-resistant metal material to prevent damage to the belt.

[0020] The nail tooth 2 consists of an upper part and a lower part. The upper part of the nail tooth 2 has an isosceles trapezoidal cross-section in the left-right direction and a rectangular cross-section in the front-back direction, with the cross-section gradually increasing in size from top to bottom. The lower part of the nail tooth 2 has an isosceles trapezoidal cross-section in the left-right direction with the waist curving inward, and both the front-back and cross-sections are rectangular. This structure of the nail tooth 2 can effectively reduce the soil penetration resistance, increase the smoothness of the soil penetration process, reduce the workload of the residual film recycling machine's power equipment, and reduce frictional damage to the nail tooth 2 during the soil penetration process.

[0021] The bottom of the spike tooth 2 is connected to the mounting base 3, and the spike tooth 2 and the mounting base 3 are integrally formed. The mounting base 3 is connected to the belt 1 by several bolts, and the nuts of the bolts are located between the outer layer 11 and the inner layer 12 of the belt 1 to prevent the bolt nuts from directly rubbing against the rotating rollers equipped with the belt 1 and causing damage to the rotating rollers.

[0022] Mounting base 3 includes an intermediate plate 32 connected to the nail teeth 2, and connecting plates 33 on the left and right sides of the intermediate plate 32. The two connecting plates 33 are symmetrically arranged, and bolt holes 31 are provided on the connecting plates 33. The intermediate plate 32 is a horizontal plate, the lower end surfaces of the two connecting plates 33 are horizontal, the upper end surfaces are inclined, and the upper end surface of the intermediate plate 32 and the upper end surfaces of the two connecting plates 33 form an upward convex structure.

[0023] The width of the mounting base 3 is smaller than the width of the belt 1 to prevent the mounting base 3 from rubbing against other components in the impurity removal mechanism; the width of the nail tooth 2 is smaller than the width of the mounting base 3, which can provide space for the residual film to deform, so as to remove impurities on the residual film.

[0024] In practical use, the belt 1 is fitted between at least two rotating rollers and is also installed in the impurity removal mechanism of the residual film recycling machine. The toothed components 2 and belt 1 are spaced apart between the impurity removal components (e.g., plates or rods) in the impurity removal mechanism. These components move in the opposite direction to the belt 1 and work in conjunction with the impurity removal components. The toothed components pierce the soil, penetrating the residual film. Then, as the belt 1 rotates, the residual film is rotated between the impurity removal components in the impurity removal mechanism. The squeezing and blocking action of the impurity removal components deforms the residual film, simultaneously removing impurities from it.
