Description

Technical Field

[0001] The utility model relates to the technical field of weed-proof cloth, in particular to a device for testing the water permeability of weed-proof cloth. Background Art

[0002] Weed-proof cloth, also known as weed-killing cloth, weed-covering cloth, and grass-covering cloth, its weed-killing principle is to block the photosynthesis of weeds by shading, so as to achieve the purpose of weed control. Since the production of weed-proof cloth is carried out by weaving, the water permeability is an important technical index of weed-proof cloth, and its purpose is to be able to maintain soil moisture, and at the same time, the ground can be kept from waterlogging and can be irrigated. Therefore, it is very necessary to test the water permeability of weed-proof cloth.

[0003] Weed-proof cloth usually uses dark woven cloth or non-woven fabric or plastic film as weed-proof cloth, which has good water permeability. Before planting, the weed-proof cloth is laid on the soil and fixed to the ground by fixing parts such as nails. After the weed-proof cloth is processed, it needs to be subjected to water permeability detection, and a water permeability quality detection device for weed-proof cloth processing will be used. When testing the water permeability of the weed-proof cloth, first spread out the weed-proof cloth, then put the weed-proof cloth into the test bench, and fix the weed-proof cloth through the fixing mechanism, and then the water permeability test can be carried out. In the existing test device, the fixing mechanism has the defects of relatively complex operation and inconvenient use. For example, the weed-proof cloth is fixed by the cooperation of components such as adjusting bolts and clamping plates. After the weed-proof cloth test is completed, the fixing of the weed-proof cloth is released again by the cooperation of components such as adjusting bolts and clamping plates.

[0004] Based on this, it is necessary to design a device for testing the water permeability of weed-proof cloth that can fix the weed-proof cloth and has simple operation. Summary of the Utility Model

[0005] The technical solution of the utility model is: a device for testing the water permeability of weed-proof cloth, which includes a base, a square frame, a convex block, a connecting frame, a second spring, a connecting rod, a clamping plate, a vertical rod, a lifting assembly and a spraying assembly. The square frame is installed on the base. The square frame has an open upper part, a closed lower part and an internal cavity, and is used for storing test water. The vertical rods are symmetrically and slidably installed on the two symmetrical outer walls of the square frame. A clamping plate is commonly connected to the adjacent two vertical rods. A connecting rod parallel to the vertical rod is arranged on the side wall of the clamping plate. The lower part of the connecting rod slidably passes through the convex block arranged on the side wall of the square frame. A connecting frame is commonly connected to the adjacent two connecting rods. A U-shaped frame is arranged between the ends of the connecting frames on the relatively symmetrical sides, and the U-shaped frame is arranged outside the square frame. A second spring is arranged between the connecting frame and the convex block, and the second spring is wound around the connecting rod. A support assembly for providing a supporting function before the weed-proof cloth is not pressed tightly is arranged on the square frame, and a spraying assembly for spraying the weed-proof cloth is also arranged on the square frame.

[0006] Furthermore, the lifting component includes a support plate, vertical rods, a U-shaped frame, a clamping block, a first spring, a T-shaped frame, and a guide plate. Guide plates are installed on the inner walls of two symmetrical positions on the upper part of the square frame. A support plate adapted to the inner cavity of the upper part of the square frame is slidably arranged on the guide plates. Rectangular guide grooves for the guide plates to pass through are formed on both symmetrical sides of the support plate. A T-shaped frame is arranged at the bottom of the support plate near the rectangular guide grooves. A clamping block that can be inserted into a V-shaped groove formed on the guide plate is slidably connected to the rod-shaped member of the T-shaped frame. The clamping block is slidably matched with the bottom of the support plate, and a first spring is arranged between the clamping block and the T-shaped frame. Vertical rods are connected to the four corners of the bottom of the support plate. The vertical rods slidably pass through the square frame, and the lower parts of two adjacent vertical rods are connected to a U-shaped frame.

[0007] Furthermore, the spraying component includes a telescopic hose, an n-shaped frame, an electric slide rail, a rigid pipe, and a nozzle. N-shaped frames are installed on the outer walls of two symmetrical sides of the square frame. An electric slide rail is arranged between the two n-shaped frames. A rigid pipe is slidably installed on the electric slide rail. No less than two nozzles are communicated with the downward side of the rigid pipe. A telescopic hose is communicated between the rigid pipe and the inner cavity of the lower part of the square frame.

[0008] Furthermore, the length of the vertical rod is the same as the length of the vertical rod extending outside the square frame.

[0009] Furthermore, a rubber pad is connected to the side of the clamping plate facing the square frame.

[0010] Furthermore, transparent observation plates are arranged on two symmetrical sides of the square frame where the n-shaped frames are not installed.

[0011] Furthermore, the number of V-shaped grooves formed on the guide plate is two, which are respectively formed on the upper part and the lower part of the guide plate.

[0012] The beneficial effects are as follows: 1. When the U-shaped frame moves downward, it drives the connecting frame to move downward. The connecting frame drives the clamping plate to move downward through the connecting rod, thereby pressing the weed-proof cloth placed on the top of the square frame and the support plate, making the weed-proof cloth closely adhere to the top of the square frame, thus realizing the function of efficiently fixing the weed-proof cloth, providing convenience for the water permeability test of the weed-proof cloth, and having the advantages of simple and efficient operation.

[0013] 2. When the support plate moves upward to be flush with the top of the square frame, the support plate provides a supporting effect for the weed-proof cloth, avoiding the center of gravity from sagging and causing the weed-proof cloth to fall into the square frame when it is not fixed circumferentially.

The support plate 7 provides support for the weed-proof cloth to prevent the weed-proof cloth from freely falling when the center of gravity is in the middle. Rectangular guide grooves for the guide plates 9 to pass through are provided on the left and right symmetric sides of the support plate 7. The number of V-shaped grooves provided on the guide plates 9 is two, which are respectively provided in the upper and lower parts of the guide plates 9. A T-shaped frame 82 is arranged at the bottom of the support plate 7 near the rectangular guide grooves. The T-shaped frame 82 is composed of a vertical plate-like member and a horizontal rod-like member perpendicular to the vertical plate-like member.

The lower parts of two adjacent vertical rods 70 are connected to a U-shaped frame 71.

[0021] As Figure 1 shown in the figure, the spraying component includes a telescopic hose 3, an n-shaped frame 4, an electric slide rail 5, a hard pipe 6 and a nozzle 61. N-shaped frames 4 are installed on the outer walls of the two symmetric sides of the square frame 2. An electric slide rail 5 is arranged between the two n-shaped frames 4.
