The second motor drives the rotating shaft to rotate, and the second baffle on the surface of the rotating shaft moves toward the unqualified product storage chamber, and the rolled ground film on the surfaces of the first baffle and the second baffle can slide into the unqualified product storage chamber, thereby achieving the purpose of separately storing the rolled ground film, which is beneficial to classifying qualified ground film and unqualified ground film.

[0038] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0039] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0041] like Figure 1-Figure 8 As shown, an agricultural mulch film strength and deformation detection device according to an embodiment of the present application includes: a frame mechanism 100 and a pulling mechanism 200.

[0042] The pulling mechanism 200 is disposed on the surface of the frame mechanism 100 , and the pulling mechanism 200 is used to pull the ground film to detect the tensile strength and deformation of the ground film.

[0043] The frame mechanism 100 includes a lower horizontal plate 110, an upper horizontal plate 120 and a vertical plate 130. The vertical plate 130 is fixed on the surface of the lower horizontal plate 110, and the upper horizontal plate 120 is installed on the top of the vertical plate 130. In a specific implementation, the lower horizontal plate 110 and the vertical plate 130 are used to support the upper horizontal plate 120.

[0044] The pulling mechanism 200 includes a first telescopic member 210 and a clamp 220. The first telescopic member 210 is installed on the lower end surface of the lower horizontal plate 110. Two clamps 220 are provided, and the two clamps 220 are respectively fixed on the lower end surface of the upper horizontal plate 120 and the movable end of the first telescopic member 210. In specific implementation, the two clamps 220 are used to clamp the two sides of the ground film, and then the first telescopic member 210 is contracted to adjust the distance between the two clamps 220, so that the two clamps 220 can pull the ground film.

[0045] The following describes the working process of an agricultural mulch film strength and deformation detection device according to a specific embodiment of the present application with reference to the accompanying drawings.

[0046] First, use the clamp 220 installed on the surface of the upper horizontal plate 120 to clamp the top of the ground film to be tested;

[0047] Then, the clamp 220 provided at the movable end of the first telescopic member 210 is used to clamp the bottom end of the ground film to be tested, and ensure that the ground film is in a naturally stretched state after clamping;

[0048] The first telescopic member 210 is adjusted to shrink, and the movable end of the first telescopic member 210 pulls the corresponding clamp 220 to move, thereby increasing the distance between the two clamps 220, so that the two clamps 220 pull the ground film to be tested, thereby achieving the purpose of testing the tensile strength and deformation of the ground film. If the ground film is broken or the deformation of the ground film is large, the tensile strength of the ground film is poor, otherwise, the tensile strength of the ground film is strong.

[0049] Therefore, according to an agricultural mulch film strength and deformation detection device according to an embodiment of the present application, two clamps 220 are used to clamp the two sides of the mulch film to be detected, and the first telescopic member 210 is adjusted to extend and retract, so that the first telescopic member 210 drives one of the clamps 220 to move, and the distance between the two clamps 220 is changed, so that the two clamps 220 pull the mulch film. By observing the deformation of the mulch film, the operator can intuitively understand the tensile strength of the mulch film.

[0050] In addition, an agricultural mulch film strength and deformation detection device according to an embodiment of the present application also has the following additional technical features:

[0051] According to some embodiments of the present application, Figure 1-2As shown, the lower cross plate 110 and the upper cross plate 120 are arranged in parallel, and the lower cross plate 110 and the upper cross plate 120 have the same specifications. The lower cross plate 110 and the upper cross plate 120 have the same specifications, which can improve the versatility between the lower cross plate 110 and the upper cross plate 120. When the lower cross plate 110 and the upper cross plate 120 are produced, the same mold can be used to reduce the types of molds used.

[0052] According to some embodiments of the present application, Figure 1-Figure 2 As shown, a first support rod 111 is fixed to the upper end surface of the lower horizontal plate 110, and the other end of the first support rod 111 is fixedly connected to the vertical plate 130. The first support rod 111 is used to support the lower horizontal plate 110 and the vertical plate 130, so that the connection between the lower horizontal plate 110 and the vertical plate 130 can be more stable.

[0053] According to some embodiments of the present application, Figure 1-Figure 2 As shown, a second support rod 121 is fixed to the lower end surface of the upper horizontal plate 120, and the other end of the second support rod 121 is fixedly connected to the vertical plate 130, and the second support rod 121 is used to support the upper horizontal plate 120 and the vertical plate 130, so that the connection between the upper horizontal plate 120 and the vertical plate 130 can be more stable; preferably, the lower horizontal plate 110 and the vertical plate 130 are vertically arranged, and the vertical plate 130 and the first telescopic member 210 are parallelly arranged, and when the first telescopic member 210 is telescoped, the clamp 220 installed at the movable end of the first telescopic member 210 can move toward the lower horizontal plate 110 or the upper horizontal plate 120.

[0054] According to some embodiments of the present application, Figure 1 and Figure 3 As shown, the clamp 220 includes a fixed clamp plate 221 and a movable clamp plate 222. The lower end surface of the upper horizontal plate 120 and the movable end of the first telescopic member 210 are respectively fixedly connected to the corresponding fixed clamp plate 221. A screw rod 223 is installed on one side of the fixed clamp plate 221. The movable clamp plate 222 is slidably sleeved on the surface of the screw rod 223. A nut 224 is screwed on the surface of the screw rod 223. The movable clamp plate 222 is located between the fixed clamp plate 221 and the nut 224. In specific implementation, the side wall of the ground film is placed between the fixed clamp plate 221 and the movable clamp plate 222, and then By rotating the nut 224, the nut 224 will move along the screw rod 223. The moving nut 224 can push the movable splint 222 until the fixed splint 221 and the movable splint 222 stably clamp the ground film, and then stop the rotation of the nut 224; preferably, the cross-section of the fixed splint 221 is L-shaped, and the opposite sides of the fixed splint 221 and the movable splint 222 are engraved with anti-slip grooves. The setting of the anti-slip grooves can increase the anti-slip effect of the fixed splint 221 and the movable splint 222, which is beneficial for the fixed splint 221 and the movable splint 222 to clamp the ground film.

[0055] According to some embodiments of the present application, Figure 1As shown, a force measuring device 230 is fixed on the surface of the upper horizontal plate 120, and the measuring end of the force measuring device 230 is connected to the clamp 220 installed at the movable end of the first telescopic member 210. In a specific implementation, when the first telescopic member 210 contracts, the clamp 220 at the movable end of the first telescopic member 210 is driven to move, and the clamp 220 at the movable end of the first telescopic member 210 will pull the ground film, and the force measuring device 230 can measure the tension of the clamp 220 at the movable end of the first telescopic member 210. Under the same tension, if the ground film is broken or deformed to a large extent, it has poor tensile strength and is a defective product. On the contrary, if the tensile strength is strong, it is a qualified product. Preferably, the force measuring device 230 is a spring dynamometer, and two force measuring devices 230 are relatively arranged. By using a spring dynamometer as the force measuring device 230, the operator can intuitively see the tension provided by the clamp 220 at the movable end of the first telescopic member 210.

[0056] When the workers unfold the ground film by pulling it and cover the ground surface, the ground film is not only subjected to tension, but the ground also supports the film. The pulling-type strength testing equipment cannot simulate the situation when the ground film covers the ground surface.

The cylinder 321 is fixedly connected to the movable end of the second telescopic member 310, the screw rod 322 is installed on one side of the cylinder 321, and the screw rod 322 is coaxially arranged with the cylinder 321, the end of the pressure strip 323 is fixedly connected to the cylinder 321, and at least two pressure strips 323 are equidistantly arranged along the circumference of the screw rod 322, and a groove 324 is formed between two adjacent pressure strips 323, and a blade 325 is slidably installed in the groove 324, and a sliding sleeve 326 is screwed on the surface of the screw rod 322, and the sliding sleeve 326 is fixedly connected to the blade 325. When the strength of the ground film is tested, the ground film can pass through the groove of the film through groove 225, and the clamp 2 After clamping the ground film, the second telescopic member 310 is adjusted, and the movable end of the second telescopic member 310 can support the pressure member 320 to move. After the movable pressure member 320 contacts the ground film, it can support the ground film to simulate the scene when the ground film covers the ground surface. When the detection is completed and the ground film is not broken, the clamp 220 releases the ground film, and the third telescopic member 330 and the second telescopic member 310 are adjusted. The movable end of the second telescopic member 310 can support the pressure member 320 and the ground film to move, and the movable end of the third telescopic member 330 can support the second telescopic member 310, so that the second telescopic member 310 is rotated to adjust the angle of the second telescopic member 310 , the movable end of the second telescopic member 310 can be moved toward the ground film recovery box 400, and the second telescopic member 310 can push the pressurizing member 320 and the ground film to move into the ground film recovery box 400, which is conducive to the recovery of the ground film; and when the ground film is wrapped on the surface of the pressurizing member 320 and it is inconvenient to recover, the screw rod 322 in the pressurizing member 320 is rotated, and the sliding sleeve 326 on the surface of the screw rod 322 will drive the blade 325 to move. When the blade 325 moves, it can cut the ground film wrapped on the surface of the pressurizing member 320. After the ground film is broken, the ground film can be more conveniently removed from the surface of the pressurizing member 320, which is conducive to the separation of the ground film and the pressurizing member 320, so that the ground film can be recovered.

[0058] Preferably, two of the cylinder 321, the second telescopic member 310 and the third telescopic member 330 are each provided, and a drive motor 327 is installed inside any one of the cylinders 321, and the output shaft of the drive motor 327 is transmission-connected to the screw rod 322. The additional drive motor 327 can be used to drive the screw rod 322, which is beneficial to the rotation of the screw rod 322; it should be noted that the blade portion of the blade 325 extends outside the groove 324, which is beneficial for the blade 325 to cut the ground film wrapped on the surface of the pressure strip 323, and an isolation ring 328 is installed on the surface of the cylinder 321, and the blade 325 is slidably inserted in the ring of the isolation ring 328. After the blade 325 is slid into the isolation ring 328, the blade 325 can be recovered, and the blade 325 will no longer cut the ground film, and the possibility of the blade 325 scratching the staff can be reduced.

[0059] After production, the mulch film will be rolled on the surface of a paper tube and then packed for transportation. When testing the mulch film, one or several rolls of mulch film are randomly selected for testing by sampling.
