Description

Technical Field

[0001] This invention relates to a water permeability testing device, and more particularly to a water permeability testing device for weed control fabric. Background Technology

[0002] Weed control fabric, also known as weed-control fabric, weed-covering fabric, or weed-covering fabric, works by blocking light to prevent weeds from photosynthesizing, thus achieving the purpose of weed control. Since weed control fabric is produced by weaving, water permeability is an important technical indicator. Its purpose is to retain soil moisture, prevent water accumulation on the ground, and allow for irrigation. Therefore, testing the water permeability of weed control fabric is very necessary.

[0003] Existing permeability testing devices often consume a lot of time due to their complex operation. During the test, the weed control fabric needs to be laid out manually, then placed on the test platform, and its size needs to be adjusted to match the weed control fabric to prevent it from collapsing during the water injection process. After the test, the weed control fabric also needs to be rolled up, making the testing process extremely cumbersome. Summary of the Invention

[0004] To overcome the drawbacks of cumbersome and complex operation of weed control fabric permeability testing devices, the technical problem to be solved is to provide a simple weed control fabric permeability testing device.

[0005] The technical solution of the present invention is: a device for testing the water permeability of weed control fabric, comprising a base, a transmission rod, a water storage pan, a cross-ring rotating frame, a pressing mechanism, a water injection mechanism, and an intermittent drive assembly. The transmission rod is rotatably connected to the base, and the cross-ring rotating frame for testing the weed control fabric is fixed to the transmission rod. The intermittent drive assembly for intermittently rotating the cross-ring rotating frame is provided on the base. The water storage pan is fixed to one side of the base. The pressing mechanism for pressing and fixing the weed control fabric is provided on the cross-ring rotating frame. The water injection mechanism for supplying water for testing the weed control fabric is provided on the water storage pan.

[0006] Furthermore, the side of the water storage tray is transparent and has graduations, which are used to compare the approximate difference between water injection and water permeation.

[0007] Furthermore, the intermittent drive assembly includes a motor, a full gear, and a missing gear. The full gear is keyed onto the transmission rod, and the motor is mounted on the base. The output shaft of the motor is keyed onto the missing gear, which meshes with the full gear.

[0008] Furthermore, the clamping mechanism includes a disc, a support frame, a toothed ring, a limiting frame, a first fixing rod, and a protrusion. The top of the transmission rod is rotatably connected to the disc. The support frame is fixedly connected to the cross-shaped rotating frame. The toothed ring is hinged to the support frame. The toothed ring and the cross-shaped rotating frame are in ring contact. The disc is fixedly connected to protrusions on both sides symmetrically around its center. The protrusions and the toothed ring are in contact. The limiting frame is fixedly connected to the water storage tray. The first fixing rod is fixedly connected to the base and is fixedly connected to the disc.

[0009] Furthermore, the water injection mechanism includes a second fixed rod, a first water storage frame, a second water storage frame, a water injection pipe, and a triggering mechanism. The first water storage frame is fixed to the water storage tray by the second fixed rod, and the second water storage frame is slidably connected inside the first water storage frame. The bottom of the first water storage frame is provided with a water injection pipe, and the bottom of the second water storage frame is provided with a water outlet. The water outlet and the water injection pipe are in contact with each other. A triggering mechanism for triggering the second water storage frame to inject water is provided on the first water storage frame.

[0010] Furthermore, the triggering mechanism includes a contact frame, a contact plate, a second guide rod, a spring, and a connecting block. The contact frame is fixedly connected to the support frame, and the second guide rods are symmetrically fixedly connected to the first water storage frame. The two second guide rods are slidably connected to the connecting block, and a spring is provided between the connecting block and the second guide rod. The contact plate is fixedly connected to the connecting block, and the contact plate and the contact frame cooperate with each other. The contact plate and the second water storage frame are fixedly connected.

[0011] Furthermore, it also includes a water measuring component, which is installed in the water storage pan to observe the water storage volume; the water measuring component includes a float and a first guide rod, the first guide rod is fixedly connected in the water storage pan, and the float is slidably connected to the first guide rod.

[0012] Furthermore, it also includes a circulation component, which is installed on the water storage pan for testing water circulation; the circulation component includes a circulation pump and a water supply pipe, one end of the water pipe is connected to the bottom of the water storage pan, the circulation pump is fixed to the side of the water storage pan, the other end of the water supply pipe is connected to the input end of the circulation pump, and the output end is connected to the first water storage frame through the water supply pipe.

[0013] During the permeability test, it is not necessary to lay out the entire weed control fabric. Instead, cut a portion of the fabric from the head of each batch and label it accordingly. The worker stands on the side adjacent to the water injection mechanism and places the weed control fabric to be tested on the ring of the rotating cross-ring frame. The motor is started, and the motor output shaft drives the transmission rod to rotate, which in turn rotates the cross-ring frame. After a quarter turn, the motor stops rotating. At this point, the protrusion disengages from the rotating toothed ring, causing it to fall and press down on the weed control fabric placed on the rotating cross-ring frame. The next rotating toothed ring contacts the protrusion and lifts up. Then, the second piece of weed control fabric is placed on the ring, awaiting the next motor rotation. After the toothed ring moves to the position of the limiting frame, the limiting frame presses the toothed ring firmly, thus fixing the weed control fabric in place by the teeth and preventing it from easily falling back into place. As the weed control fabric slides down, it moves to the bottom of the first water storage frame during rotation. The contact frame then lifts the contact plate and simultaneously lifts the second water storage frame. Once lifted to its maximum height, the outlet of the water injection pipe and the outlet of the second water storage frame align, allowing water from the second water storage frame to flow into the weed control fabric. Leaking water falls into the water storage pan. After a brief pause, the motor continues to rotate a quarter turn. If, within the interval between two motor rotations, the water on the weed control fabric below the water injection mechanism cannot be completely permeated, the permeability is considered unqualified; otherwise, it is considered qualified. The cross-shaped rotating frame is then rotated to the other side, where the weed control fabric is collected and processed by workers. The above steps are repeated to test different weed control fabrics sequentially. By conducting random testing in this way, the permeability of the weed control fabric can be quickly tested, greatly reducing testing time.

[0014] After water is injected and leaks through the weed control fabric into the water storage pan, the circulation pump is started. The circulation pump then transports the water in the water storage pan to the first water storage frame through the water supply pipe, thus completing the recycling of the test water.

[0015] The beneficial effects are: under the action of the cross-shaped rotating frame and the water injection mechanism, the water permeability test is carried out by partially testing the same batch of weed control fabric. This eliminates the water stains and losses left on the weed control fabric, and the test results can be obtained quickly and intuitively. Compared with existing testing methods, the testing time is greatly reduced.

[0016] With the help of the circulation component, the test water supply can be recycled, which can greatly reduce water waste and lower operating costs. Attached Figure Description

Detailed Implementation

[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Example 1

[0030] A device for testing the water permeability of weed control fabric, such as Figure 1 , Figure 2As shown, the device includes a base 1, a transmission rod 4, a water storage tray 5, a cross-ring rotating frame 6, a pressing mechanism 7, a water injection mechanism 8, and an intermittent drive assembly. The transmission rod 4 is rotatably connected to the base 1, and the cross-ring rotating frame 6 for testing the weed control fabric is fixed to the transmission rod 4. An intermittent drive assembly is provided on the base 1 to allow the cross-ring rotating frame 6 to rotate intermittently. A water storage tray 5 for collecting water leaking from the weed control fabric is fixed to one side of the base 1. A pressing mechanism 7 for pressing and fixing the weed control fabric is provided on the cross-ring rotating frame 6. A water injection mechanism 8 for supplying water for testing the weed control fabric is provided on the water storage tray 5. The side of the water storage tray 5 is transparent and has scales for comparing the approximate difference between water injection and water leakage. After removing the water loss adhering to the weed control fabric, the water remaining in the water storage tray 5 can be used to determine whether the weed control fabric is qualified by the scale value.

[0031] like Figure 1 , Figure 3 As shown, the intermittent drive assembly includes a motor 2, a full gear 3, and a missing gear 301. The full gear 3 is keyed onto the transmission rod 4. The motor 2 is mounted on the base 1. The output shaft of the motor 2 is keyed onto the missing gear 301. The missing gear 301 meshes with the full gear 3. The missing gear 301 is one-quarter of the full gear 3. When the missing gear 301 rotates one revolution, the full gear 3 rotates one-quarter revolution.

[0032] like Figure 1 , Figure 4 , Figure 5 As shown, the clamping mechanism 7 includes a disc 701, a support frame 702, a toothed ring 703, a limiting frame 704, a first fixing rod 705, and a protrusion 706. The top of the transmission rod 4 is rotatably connected to the disc 701. The support frame 702 is symmetrically fixed to the front and back, and left and right sides of the cross-shaped rotating frame 6. The toothed ring 703 is hinged to the support frame 702. The toothed ring 703 has toothed nails. The ring on the cross-shaped rotating frame 6 has grooves that fit with the toothed nails. After the weed control cloth is placed on the ring on the cross-shaped rotating frame 6, the weed control cloth can be clamped and fixed by clamping the toothed ring 703. The disc 701 is symmetrically fixed with protrusions 706 on both sides of the center. After the protrusions 706 and the toothed ring 703 come into contact, the protrusions 706 press the toothed ring 703 down with the support frame 702 as the fulcrum, so that the toothed ring 703 can be lifted up to better place the weed control cloth. The water storage disc 5 is fixed with a limiting frame 704. The limiting frame 704 has a limiting opening. After the toothed ring 703 moves to the limiting opening, it can fit tightly with the ring on the cross ring rotating frame 6. The base 1 is fixed with a first fixing rod 705. The first fixing rod 705 is fixed to the disc 701 to prevent the disc 701 from rotating.

[0033] like Figure 1 , Figure 6 , Figure 7As shown, the water injection mechanism 8 includes a second fixed rod 801, a first water storage frame 802, a second water storage frame 803, a water injection pipe 804, and a triggering mechanism 10. The first water storage frame 802 is bolted to the water storage tray 5 via the second fixed rod 801. The second water storage frame 803 is slidably connected inside the first water storage frame 802. In the initial state, the height of the second water storage frame 803 is lower than that of the first water storage frame 802. The water injection pipe 804 is fixedly connected to the bottom of the first water storage frame 802. The bottom of the second water storage frame 803 is provided with a water outlet 805. The triggering mechanism 10 for triggering the injection of water into the second water storage frame 803 is provided on the first water storage frame 802. After the water outlet 805 of the second water storage frame 803 slides to coincide with the water injection pipe 804, the water in the second water storage frame 803 flows into the water injection pipe 804 through the water outlet 805 and is discharged. When in use, the first water storage frame 802 is first filled with water, and then the second water storage frame 803 is filled.

[0034] like Figure 1 , Figure 9 , Figure 10 As shown, the triggering mechanism 10 includes a contact frame 101, a contact plate 102, a second guide rod 103, a spring 104, and a connecting block 105. Contact frames 101 are fixedly connected to all four support frames 702. Second guide rods 103 are symmetrically fixed to the first water storage frame 802. The two second guide rods 103 are slidably connected to the connecting block 105. A spring 104 is provided between the connecting block 105 and the second guide rod 103. The contact plate 102 is fixedly connected to the connecting block 105. The contact plate 102 and the second water storage frame 803 are fixedly connected. After the contact frame 101 and the contact plate 102 come into contact, the contact plate 102 is lifted up and the spring 104 is compressed. During the upward movement of the contact plate 102, the second water storage frame 803 is pulled to its maximum height. After the second water storage frame 803 is higher than the first water storage frame 802, the water outlet 805 and the water injection pipe 804 coincide. After the contact frame 101 and the contact plate 102 are separated, the spring 104 is reset and the water outlet 805 and the water injection pipe 804 are staggered.

[0035] During the permeability test, it is not necessary to lay out the entire weed control fabric. For each batch of weed control fabric, only the head portion is cut and labeled accordingly. The worker stands on the side adjacent to the water injection mechanism 8, places the weed control fabric to be tested on the ring of the cross-ring rotating frame 6, and starts the motor 2. The output shaft of motor 2 drives the transmission rod 4 to rotate, which in turn drives the cross-ring rotating frame 6 to rotate. After rotating a quarter turn, motor 2 stops rotating. At this time, the protrusion 706 disengages from the rotating toothed ring 703, and the toothed ring 703 falls, pressing down on the weed control fabric placed on the cross-ring rotating frame 6. The next rotating toothed ring 703 contacts the protrusion 706 and lifts up. Then, the second piece of weed control fabric is placed on the ring, waiting for the next rotation of motor 2. After the toothed ring 703 moves to the position of the limiting frame 704, the limiting frame 704 presses the toothed ring 703 tightly, thus fixing the weed control fabric in place by the toothed ring. It will easily slip off. At this time, the weed control fabric moves to the bottom of the first water storage frame 802 during rotation. The contact frame 101 lifts the contact plate 102 and simultaneously lifts the second water storage frame 803. After being lifted to the maximum height, the outlet of the water injection pipe 804 and the water outlet 805 of the second water storage frame 803 coincide. At this time, the water in the second water storage frame 803 is injected into the weed control fabric. The leaked water will fall into the water storage pan 5. After stopping at the interval, the motor 2 continues to rotate a quarter turn. If the water on the weed control fabric located below the water injection mechanism 8 cannot be completely penetrated within the interval between two rotations of the motor 2, it means that the water permeability is unqualified. Otherwise, it is qualified. Rotate the cross ring rotating frame 6 to the other side. The weed control fabric is collected by the worker for processing. Repeat the above steps to test different weed control fabrics in turn. By conducting the test in the above way in a random test manner, the water permeability of the weed control fabric can be tested quickly, which greatly reduces the test time. Example 2

[0036] Based on Example 1, such as Figure 1 , Figure 8 As shown, it also includes a water measuring component 9. The water measuring component 9 is installed in the water storage pan 5 to observe the water storage volume. The water measuring component 9 includes a float 901 and a first guide rod 902. The first guide rod 902 is fixedly connected in the water storage pan 5. The float 901 is slidably connected to the first guide rod 902. When the water volume in the water storage pan 5 increases and rises, the float 901 moves upward by buoyancy. The rising of the float 901 can be observed through the transparent plate on the side of the water storage pan 5.

[0037] like Figure 1 , Figure 11As shown, it also includes a circulation component 11. The water storage pan 5 is provided with a circulation component 11 for testing water supply circulation. The circulation component 11 includes a circulation pump 111 and a water supply pipe 112. One end of the water pipe is connected to the bottom of the water storage pan 5. The circulation pump 111 is fixed to the side of the water storage pan 5. The other end of the water supply pipe 112 is connected to the input end of the circulation pump 111. The output end is connected to the first water storage frame 802 through the water supply pipe 112.

[0038] After water is injected and leaks into the water storage pan 5 through the weed control cloth, the circulation pump 111 is started. The circulation pump 111 transports the water in the water storage pan 5 to the first water storage frame 802 through the water supply pipe 112, thereby completing the recycling of the test water.
