Description

Technical Field

[0001] This utility model relates to the field of agricultural auxiliary equipment technology, specifically a poplar seedling weed control cloth fixing device. Background Technology

[0002] Weed control fabric is made of opaque cloth that covers the soil. Grass is a type of plant that needs sunlight to grow. The area covered by the weed control fabric does not receive sunlight for a long time, so naturally there are no conditions for grass to grow. When installing weed control fabric, it is necessary to use fixing devices to secure it.

[0003] According to the utility model patent application CN217184088U, a weed control fabric fixing device is disclosed, including a post, a weed control fabric fixing structure, and a bottom fixing structure. The weed control fabric fixing structure and the bottom fixing structure are both located on the post. The weed control fabric fixing structure includes a pressure plate, a rope hole, and a fixing rope. The pressure plate is located on the post, the rope hole passes through the pressure plate, and the fixing rope passes through the pressure plate. This device effectively solves the problem of weed control fabric fixing devices on the market, when used with soil, in windy and rainy weather. The current device addresses the problem of the fabric being rolled up. It simply uses a fixing rope tied to the rope hole on the pressure plate and then pulled taut to secure the fabric. This method cannot tightly secure the four sides of the fabric, allowing strong winds to easily reach underneath, causing the fabric to lift up or even be damaged. Furthermore, different lengths of fixing ropes are required when securing different types of fabric, making the device cumbersome and reducing its practicality. Therefore, we provide a poplar seedling weed control fabric fixing device to solve these problems. Utility Model Content

The four-corner positioning mechanism 3 includes two sets of main fixing columns 301, the top of the two sets of main fixing columns 301 are fixedly connected to the bottom surface of the two sets of mounting cylinders 201 respectively. The main fixing columns 301 can be inserted through the weed control cloth body 1 and below the ground to pre-fix the four corners of the weed control cloth body 1.

[0022] Reference Figure 4 Each set of mounting cylinders 201 has two mounting blocks 303 fixedly connected to its upper surface. Each set of mounting blocks 303 has a lifting handle 304 movably hinged to its upper surface. The two mounting blocks 303 enable the lifting handle 304 to be hinged to the upper surface of the mounting cylinder 201, thus facilitating the use of the lifting handle 304 to pull the mounting cylinder 201 and the main fixing column 301 up and down.

[0023] Reference Figure 1 , Figure 2 and Figure 3 Each set of mounting cylinders 201 has a first connecting strip 202 and a second connecting strip 203 fitted on its outer surface. The bottom surface of each set of first connecting strips 202 and the bottom surface of each set of second connecting strips 203 are in contact with the upper surface of the weed control fabric body 1. The upper surface of the weed control fabric body 1 has two sets of sliding mounting holes 302. Two sets of main fixing posts 301 are slidably connected to the inside of the two sets of sliding mounting holes 302. The main fixing posts 301 pass through the sliding mounting holes 302 and can block the weed control fabric body 1, so as to facilitate the fixing of the four corners of the weed control fabric body 1.

[0024] Reference Figure 3 and Figure 4Each set of first connecting strips 202 has a sliding limiting groove 204 on its bottom surface. Two sets of second connecting strips 203 are slidably connected to the inside of the two sets of sliding limiting grooves 204. Each set of main fixing columns 301 has arc-shaped plates 305 arranged circumferentially at equal intervals inside. The bottom surfaces of the two sets of arc-shaped plates 305 are fixedly connected to the inner bottom walls of the two sets of main fixing columns 301. Multiple arc-shaped plates 305 are arranged inside the main fixing columns 301, and the bottom of the arc-shaped plates 305 is fixed to the inner bottom wall of the main fixing columns 301, while the top of the multiple arc-shaped plates 305 is not fixed to the inner wall of the main fixing columns 301, so that the top of the multiple arc-shaped plates 305 can slide inside the main fixing columns 301.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Each set of first connecting strips 202 and each set of second connecting strips 203 have sliding connecting grooves 205 on their upper surfaces. The upper surface of the weed control fabric body 1 has two sets of extension fixing holes 206. Each set of extension fixing holes 206 has a pin 207 slidably connected inside. The bottom ends of the two sets of pins 207 pass through the two sets of sliding connecting grooves 205 and the two sets of extension fixing holes 206 respectively and extend to the bottom of the weed control fabric body 1. Each set of arc plates 305 has a telescopic spring 306 arranged in a circular pattern at equal intervals on its opposite sides. The opposite ends of the two sets of telescopic springs 306 are fixedly connected to the inner walls of the two sets of main fixing posts 301 respectively. The telescopic springs 306 are fixed between the arc plates 305 and the main fixing posts 301, so as to facilitate the adjustment of the distance between the arc plates 305 and the main fixing posts 301.

[0026] Reference Figure 1 , Figure 3 and Figure 4 Each set of pins 207 has a baffle 208 fixedly connected to its top. The bottom surfaces of the two sets of baffles 208 are in contact with the upper surfaces of the two sets of first connecting strips 202 respectively. Each set of baffles 208 has a pull handle 209 fixedly connected to its upper surface. The two sets of arc plates 305 have equally spaced connecting barbs 307 fixedly connected to their respective sides. Each set of main fixing posts 301 has equally spaced protrusion holes 308 on its outer surface. The two sets of connecting barbs 307 are slidably connected to the inside of the two sets of protrusion holes 308 respectively. The connecting barbs 307 fixed to the outside of the arc plate 305 extend from the protrusion holes 308 and can be inserted into the ground to improve the connection stability between the main fixing post 301 and the ground.

[0027] Reference Figure 1 and Figure 4Each of the two sets of arc-shaped plates 305 has a tapered extrusion rod 309 on one side that is close to each other. The top of each tapered extrusion rod 309 is fixedly connected to a push rod 310. The two sets of push rods 310 are slidably connected to the inside of the two sets of mounting cylinders 201. The top of each set of push rods 310 is fixedly connected to an extrusion plate 311. By manually holding the extrusion plate 311, the push rod 310 can push the tapered extrusion rod 309 into the inside of the main fixing column 301 to extrude the arc-shaped plate 305, thereby allowing the connecting barb 307 to extend from the protrusion hole 308 and insert into the ground.

[0028] Working principle: When using this fixing device to fix the weed control cloth for poplar seedlings, firstly, holes for the poplar seedlings are opened on the surface of the main body 1 of the weed control cloth manually, so that the main body 1 of the weed control cloth can be put on the outside of the poplar seedlings and the bottom surface of the main body 1 of the weed control cloth is in contact with the ground surface. Then, the first connecting strip 202 and the second connecting strip 203 are passed through the main fixing post 301 to the outside of the mounting cylinder 201 manually, and the corresponding second connecting strip 203 is slidably locked into the sliding limiting groove 204 opened on the bottom surface of the first connecting strip 202, so that the first connecting strip 202 and the second connecting strip 203 can cooperate.

[0029] Next, by manually holding the lifting handle 304 hinged to the mounting block 303 on the mounting cylinder 201, the corresponding main fixing post 301 and the mounting cylinder 201 can be passed through the sliding mounting hole 302 opened on the weed control fabric body 1. This allows the bottom surfaces of the multiple first connecting strips 202 and second connecting strips 203 to contact and press against the upper surface of the weed control fabric body 1, so that the main fixing post 301 can be stably inserted below the ground. Then, by manually holding the pulling handle 209, the baffle 208 can be used to pull the pin 207 through the sliding connecting groove 205 opened on the first connecting strip 202 and second connecting strip 203, and through the extension fixing hole 206 opened on the weed control fabric body 1, so that the pin 207 can be inserted below the ground. This allows the baffle 208 to press and tighten the upper surface of the first connecting strip 202, so that the structure composed of the first connecting strip 202 and the second connecting strip 203 can be used to press and fix the four sides of the weed control fabric body 1.

[0030] Then, by manually holding the extrusion plate 311, the push rod 310 and the conical extrusion rod 309 can pass through the mounting cylinder 201 and be inserted into the interior of the main fixing post 301. Since multiple arc-shaped plates 305 are provided inside the main fixing post 301, and a telescopic spring 306 is fixed between the arc-shaped plates 305 and the main fixing post 301, the telescopic spring 306 will be compressed under the pressure of the conical extrusion rod 309, causing the multiple arc-shaped plates 305 to move away from each other. Furthermore, the arc-shaped plates 305... Multiple connecting barbs 307 are fixed in place so that when the arc plate 305 is close to the inner wall of the main fixing post 301, the connecting barbs 307 can extend from the protrusion holes 308 opened on the outside of the main fixing post 301 to the outside, so that the connecting barbs 307 can be inserted into the soil to fix the main fixing post 301. This fixing device can be used to install and fix the four corners of the weed control cloth body 1, and thus the weed control cloth body 1 can be fixed conveniently and stably using the poplar seedling weed control cloth fixing device.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
