Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of edge cutting V belt for agricultural machinery, concretely relates to double -deck line rope reinforced type edge cutting V belt and adopt the edge cutting V belt's residual film machine belt. BACKGROUND

[0002] In the agricultural planting process, usually a layer of plastic mulch is covered on the farmland surface or crop ridge, which plays a role in warming and preserving soil moisture, so as to improve the yield and quality of crops (such as cotton, corn, peanut, etc.). But the traditional plastic mulch is difficult to degrade naturally, and the residual plastic mulch in the soil can destroy the soil structure, affect the growth of crop roots and water and fertilizer absorption; and the residual film is easy to be blown to the field head, canal, forest belt, causing environmental pollution. Therefore, after the crops are harvested, the plastic mulch remaining in the farmland needs to be recycled. At present, residual film recycling machine is generally used to directly pick up and transport the plastic mulch from the surface by using the residual film machine belt with nails or protrusions.

[0003] The existing edge cutting V belt for agricultural machinery usually needs to be prepared according to the technical specifications in the national standard GB / T 14829 "Variable speed V belt for agricultural machinery", which generally includes top cloth, top glue, buffer glue, tensile body, bottom glue, bottom glue sandwich, bottom cloth, etc.; among them, the buffer glue generally uses short fiber glue to improve the transverse stiffness. However, when the edge cutting residual film machine belt produced according to the above national standard is used with the residual film recycling machine to recycle the residual film in the farmland, the edge cutting residual film machine belt is easy to break due to the excessive load of the machine. At this time, the residual film recycling process is slowed down, and the farm time is delayed. How to solve the problem of easy breakage of the edge cutting residual film machine belt caused by the heavy load of the residual film recycling machine mainly lies in improving the tensile strength and overload capacity of the edge cutting residual film machine belt. The commonly used method in the prior art is to apply high-strength super material (such as aramid fiber or carbon fiber super strong material) to the preparation of the edge cutting residual film machine belt. However, the manufacturing cost of aramid fiber and carbon fiber super strong material is very high, and the production and scale effect is insufficient, which is not conducive to popularization and use in the agricultural machinery market. UTILITY MODEL CONTENTS

[0004] In order to overcome the above problems existing in the prior art, the utility model provides a double -deck line rope reinforced type edge cutting V belt, which adopts the structure design of double -deck skeleton line rope and multiple layers of canvas superposition, has good tensile strength and overload capacity, and the material cost of each layer of the edge cutting V belt is low, which can be processed by conventional processing equipment, and the process is simple, economical and good, which is suitable for batch popularization and use in the agricultural machinery industry. Correspondingly, the application also provides a residual film machine belt using the above edge cutting V belt, which has high overall structural strength and is not easy to break when used with the residual film recycling machine, and has good practicability.

[0005] For the edge cutting V belt, the technical scheme of the application is:

[0006] The double-layer wire rope reinforced cut-edge V belt comprises, in sequence, a top cloth layer, a framework layer, a reinforcing layer, a bottom rubber layer and a bottom cloth layer; the framework layer comprises, in sequence, an A adhesive rubber layer, a first short fiber rubber layer and a B adhesive rubber layer; a group of A framework wire ropes are arranged in the A adhesive rubber layer in parallel at intervals along the width direction of the cut-edge V belt; the first short fiber rubber layer is located at the pitch line position of the cut-edge V belt; a group of B framework wire ropes are arranged in the B adhesive rubber layer in parallel at intervals along the width direction of the cut-edge V belt; the reinforcing layer is formed by stacking a plurality of canvases, and adjacent two canvases are fixed by a C adhesive rubber layer.

[0007] Compared with the prior art, the double-layer wire rope reinforced cut-edge V belt has the following advantages: (1) the framework layer adopts a double-layer framework wire rope structure design, and the two framework wire ropes are separated by the short fiber rubber layer to prevent the framework wire ropes from being misaligned, thereby effectively improving the tensile strength of the cut-edge V belt; (2) the reinforcing layer adopts a structure design of stacking a plurality of canvases, which is beneficial to improving the repeated flex fatigue resistance and overload resistance of the cut-edge V belt, avoiding damage caused by local stress concentration, thereby preventing the cut-edge V belt from being broken during long-time use and prolonging the service life; (3) the materials used in each layer of the cut-edge V belt have low cost, and the cut-edge V belt can be processed by conventional processing equipment, so that the process is simple, the economy is good, and the cut-edge V belt is suitable for batch promotion and use in the agricultural machinery industry.

[0008] As an optimization, in the foregoing double-layer wire rope reinforced cut-edge V belt, a second short fiber rubber layer is arranged between the top cloth layer and the framework layer; a third short fiber rubber layer is arranged between the framework layer and the reinforcing layer; and a fourth short fiber rubber layer is arranged between the reinforcing layer and the bottom rubber layer. Arranging the short fiber rubber layers between the top cloth layer and the framework layer, between the framework layer and the reinforcing layer and between the reinforcing layer and the bottom rubber layer is beneficial to improving the tear resistance of the cut-edge V belt and inhibiting the initiation and growth of fatigue cracks.

[0009] As an optimization, in the foregoing double-layer wire rope reinforced cut-edge V belt, the A framework wire ropes and the B framework wire ropes are polyester wire ropes. The polyester wire ropes have high tensile strength and good fatigue resistance, and can bear a large tensile force during use, which is beneficial to improving the load-carrying capacity and transmission efficiency of the cut-edge V belt. Further, the diameter of the polyester wire ropes can be 0.8-2.5 mm.

[0010] As an optimization, in the aforementioned double-layer cord-reinforced cut-edge V belt, the top cloth layer is a canvas layer. The canvas is woven by high-strength warp and weft threads, and has good wear resistance, transverse rigidity and dimensional stability. Using canvas as the top cloth layer can effectively resist wear and tear, prevent the cut-edge V belt from being damaged due to excessive wear of the surface rubber, and cause the internal framework layer to be damaged, leading to the premature scrapping of the entire cut-edge V belt, and can also prevent serious transverse twisting, edge curling or wrinkling during work, thereby ensuring the quality of field work. Further, the bottom cloth layer is a non-woven cloth layer. The non-woven cloth is made of randomly interlaced fibers, and has a soft structure and a high friction coefficient. Using non-woven cloth as the bottom cloth layer can better fit the pulley and generate greater friction, thereby effectively reducing slippage, reducing stress concentration, and improving transmission stability.

[0011] As an optimization, in the aforementioned double-layer cord-reinforced cut-edge V belt, the reinforcing layer is composed of five layers of canvas; the short fiber adhesive layer includes an adhesive matrix and short fibers uniformly dispersed in the adhesive matrix; the short fibers can be nylon short fibers, polyester short fibers, cotton fibers or cotton powder short fibers.

[0012] For the residual film machine belt, the technical solution of the present application is:

[0013] The residual film machine belt comprises a belt body and a plurality of iron claws arranged on the belt body in a circumferential direction; the belt body adopts the aforementioned double-layer cord-reinforced cut-edge V belt.

[0014] Compared with the prior art, the belt body of the residual film machine belt of the present application adopts a structure design of double-layer framework cord and multiple layers of canvas, has good tensile strength and overload resistance, so that the belt body is not easy to break when used with a residual film recycling machine, and has good practicality; moreover, the materials used in each layer of the belt body have low cost, and the belt body can be processed by conventional processing equipment, so the process is simple and economical, and the residual film machine belt is suitable for batch use in the agricultural machinery industry.

[0015] As an optimization, in the aforementioned residual film machine belt, the bottom of the iron claw is provided with an arc-shaped mounting plate; the arc-shaped mounting plate is in contact with the outer circumferential surface of the belt body, and the arc-shaped mounting plate and the belt body are provided with bolt holes corresponding thereto and are connected and fixed by bolts. At this time, the structure is simple and easy to assemble. Further, a groove is provided on the inner side surface of the belt body, and the head of the bolt is located in the groove. In this way, after the cut-edge V belt is deformed due to extrusion, the head of the bolt can be prevented from interfering with the cut-edge V belt, so that the cut-edge V belt is not damaged due to the reaction force of the bolt head.

[0022] In order to solve the problem that the cutting edge residual film machine belt is easy to break due to the large load in the use of the residual film recycling machine, the present application provides a residual film machine belt adopting a double-layer rope reinforced cutting edge V belt. Referring to Figs. 1 to 4 , the residual film machine belt of the present application comprises a belt body and a group of iron claws 9 arranged on the belt body in a circumferential direction; the belt body is a double-layer rope reinforced cutting edge V belt, which comprises a top cloth layer 1, a skeleton layer 2, a reinforcing layer 3, a bottom adhesive layer 4 and a bottom cloth layer 5 arranged in sequence; the skeleton layer 2 comprises an A adhesive layer 21, a first short fiber adhesive layer 22 and a B adhesive layer 23 arranged in sequence; a group of A skeleton ropes 24 are arranged in the A adhesive layer 21 in parallel along the width direction of the cutting edge V belt; the first short fiber adhesive layer 22 is located at the pitch line position of the cutting edge V belt (the length does not elongate or shorten after bending); a group of B skeleton ropes 25 are arranged in the B adhesive layer 23 in parallel along the width direction of the cutting edge V belt; the reinforcing layer 3 is formed by stacking a plurality of canvases 31, and the adjacent two canvases 31 are fixed by the C adhesive layer 32.

[0023] The belt body of the residual film machine belt of the present application adopts the structure design of double-layer skeleton rope and multiple layers of canvas stacking, so that it has good tensile strength and overload resistance, high overall structural strength, is not easy to break when used with the residual film recycling machine, and has good practicability; in addition, the raw materials used in each layer of the belt body, such as the top cloth layer 1, the skeleton layer 2, the reinforcing layer 3, the bottom adhesive layer 4 and the bottom cloth layer 5, are relatively common, and can be processed by conventional processing equipment, so that the process is simple, the manufacturing cost is low, the economy is good, and the residual film machine belt of the present application can be widely used in the agricultural machinery industry.

[0024] Embodiment:

[0025] In this embodiment, the inside of the belt has a tooth shape; the reinforcing layer 3 is composed of five layers of canvas 31.

[0026] In this embodiment, a second short fiber glue layer 6 is arranged between the top cloth layer 1 and the framework layer 2; a third short fiber glue layer 7 is arranged between the framework layer 2 and the reinforcing layer 3; and a fourth short fiber glue layer 8 is arranged between the reinforcing layer 3 and the bottom glue layer 4; the short fiber glue layer (commercially available) comprises an adhesive matrix and short fibers uniformly dispersed in the adhesive matrix; the short fibers are polyester short fibers. The arrangement of the short fiber glue layer between the top cloth layer 1 and the framework layer 2, between the framework layer 2 and the reinforcing layer 3, and between the reinforcing layer 3 and the bottom glue layer 4 makes the overall integrity of the cut edge V belt better, the dimensional stability higher, and is conducive to improving the tear resistance of the cut edge V belt and inhibiting the initiation and growth of fatigue cracks. Compared with the use of pure high-performance rubber or a full fabric framework, the use of a short fiber glue layer has a lower cost.

[0027] In this embodiment, the A framework cord 24 and the B framework cord 25 are polyester cords (commercially available); the diameter of the polyester cord is 1.5 mm. The polyester cord has high tensile strength and good fatigue resistance, and can withstand a large tensile force during use, which is conducive to improving the carrying capacity and transmission efficiency of the cut edge V belt.

[0028] In this embodiment, the top cloth layer 1 is a canvas layer (commercially available); and the bottom cloth layer 5 is a non-woven fabric layer (commercially available). During field operation, the top cloth layer 1 needs to directly withstand the severe friction and scraping of soil, sand, residual film and crop root stubble; the use of canvas as the top cloth layer 1 can effectively resist wear and tear, prevent the cut edge V belt from being damaged due to excessive wear of the surface rubber and damage to the internal framework layer, leading to early scrapping of the entire cut edge V belt, and also prevent serious transverse twisting, edge curling or wrinkling during work, thereby ensuring the quality of field operation. The non-woven fabric is made of randomly interlaced fibers, and has a soft structure and a high friction coefficient. The use of non-woven fabric as the bottom cloth layer 5 can better fit the pulley and generate greater friction, thereby effectively reducing the slip and stress concentration and improving the transmission stability.

[0029] In this embodiment, the bottom of the iron claw 9 is provided with an arc-shaped mounting plate 91; the arc-shaped mounting plate 91 is in contact with the outer peripheral surface of the belt body and is connected and fixed by the bolt 10. At this time, the connection structure is simple and easy to assemble, and has high connection stability. Two bolt holes are arranged at intervals on the arc-shaped mounting plate 91. After the cut edge V belt is produced, holes are punched at the corresponding positions, and the arc-shaped mounting plate 91 is fixed on the belt body by the bolt 10.

[0030] Further, the inner side of the belt body is provided with a groove, and the head of the bolt 10 is located in the corresponding groove. Thus, the head of the bolt 10 can be prevented from interfering with the cut edge V belt after the cut edge V belt is deformed due to extrusion, so that the cut edge V belt is damaged due to the reaction force of the head of the bolt 10.

[0031] It should be noted that the double-layer wire rope reinforced cut edge V belt is developed according to the actual needs of the film residue recycling machine, but is not limited to use on the film residue recycling machine, and can also be used in other machines.
