Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, specifically relating to a perforated weed-proof cloth covering structure for tomato cultivation. Background Technology

[0002] In the cultivation of vegetables such as tomatoes, weeds not only compete with tomato plants for soil moisture, nutrients, and sunlight, but also become breeding grounds and vectors for pests and diseases, posing a serious threat to the healthy growth of tomatoes. Currently, one of the traditional methods of weed control is to use perforated weed control fabric for mulching. This method can prevent weed growth while allowing water, air, and some nutrients to pass through, thus meeting the basic needs of tomato plant growth.

[0003] However, the traditional process of laying perforated weed control fabric usually requires manual operation. Operators need to hold the fabric rolls, guide them along the predetermined planting rows, and continuously rotate the rolls to achieve continuous laying. This process not only requires bending over, which easily leads to back fatigue and is physically demanding, but it is also inefficient. Especially in large-scale planting, manual laying of weed control fabric consumes a significant amount of manpower and time. Summary of the Invention

[0004] The purpose of this invention is to provide a perforated weed-control fabric covering structure for tomato cultivation, in order to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A perforated weed-control fabric covering structure for tomato cultivation includes a mounting frame. The mounting frame has rotatable wheels mounted on its lower left and right sides. A rotating rod rotatably mounted on the upper side of the mounting frame faces left and right. A left baffle, concentrically fixed, is rotatably mounted on the left side of the rotating rod, and a matching right baffle is mounted on the right side of the rotating rod. An adjustment component for controlling the left and right movement of the right baffle is mounted on the right side of the mounting frame. A handrail is mounted on the middle of the front side of the mounting frame.

[0007] The adjustment assembly includes a slide rod fixed to the mounting bracket. A slider is slidably mounted on the upper side of the slide rod. A lead screw is mounted on the rear side of the slide rod, which is rotatably connected to the mounting bracket and threadedly connected to the slider. A crank handle, which is rotatably connected to the lead screw, is rotatably mounted on the right side of the mounting bracket. A connecting bracket is hinged vertically to the rear side of the slider. A circular hole larger than the diameter of the rotating rod is opened on the rear side of the connecting bracket. The left baffle is rotatably connected to the left side of the connecting bracket.

[0008] A friction disc is fixedly installed on the left side of the left baffle, and an elastic telescopic rod is fixedly installed on the left side of the mounting bracket. A friction block matching the friction disc is fixedly installed on the upper side of the telescopic end of the elastic telescopic rod.

[0009] The right end of the rotating rod has an arc-shaped bevel.

[0010] The handrail includes a main rod, which is fixedly connected to the mounting bracket. The front end of the main rod has a retraction notch. A quick-release tube clamp matching the retraction notch is installed on the outside of the main rod. A sub-rod is slidably assembled on the inside of the main rod, and a rubber grip is installed on the upper end of the sub-rod.

[0011] Both the slide rod and the lead screw are fitted with telescopic protective sleeves.

[0012] In use, the rolled perforated weed control fabric is installed on the upper side of the rotating rod. Left and right baffles secure the fabric. When weed control needs to be covered, the operator holds the handle, and the wheels on the lower left and right sides of the mounting frame allow the entire structure to move easily in the field. With the handle, operators do not need to exert effort in carrying or back-operating, greatly saving physical strength and reducing back fatigue, thus improving the efficiency of weed control coverage. It allows for rapid weed control coverage in different planting areas. The adjustment component, through the cooperation of a crank, lead screw, and slider, allows the operator to easily move the right baffle left and right by simply turning the crank, thereby securing the weed control fabric roll to the rotating rod. This simple and intuitive adjustment method also allows the component to secure weed control fabric rolls of different widths, improving its applicability. The elastic telescopic rod ensures that the friction block remains in constant contact with the friction disc, generating frictional resistance. This prevents the rotating rod and the upper-mounted perforated weed control fabric from rotating on their own when not needed, and from rotating excessively during installation, thus ensuring the stability of the weed control fabric. The curved bevel design allows the right baffle and connecting frame to be easily rotated onto the upper side of the rotating rod during installation, improving operational convenience. The sub-rod can slide back and forth within the main rod and is secured by quick-release clamps. This allows operators to flexibly adjust the overall length of the handrail according to their height and operating habits, making operation more comfortable and convenient while reducing the overall footprint when not in use. The rubber grip provides some shock absorption, contributing to improved grip comfort. The telescopic protective sleeve effectively prevents dust, dirt, and other impurities from entering the gap between the sliding rod and the lead screw, ensuring smooth operation of the adjustment components. It also acts on the sliding rod and lead screw, extending the service life of the components. Attached Figure Description

Detailed Implementation

[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-6 As shown, a perforated weed control fabric covering structure for tomato cultivation includes a mounting frame 1. Wheels 2 are rotatably mounted on the lower left and right sides of the mounting frame 1. A rotating rod 3 facing left and right is rotatably mounted on the upper side of the mounting frame 1. A left baffle 4, concentrically fixed to the left side of the rotating rod 3, is rotatably mounted on the right side of the rotating rod 3. A matching right baffle 5 is mounted on the right side of the mounting frame 1. An adjustment component for controlling the left and right movement of the right baffle 5 is mounted on the right side of the mounting frame 1. A handrail 6 is mounted on the middle of the front side of the mounting frame 1.

[0023] When in use, the rolled perforated weed control fabric is installed on the upper side of the rotating rod 3. The left baffle 4 and right baffle 5 are used to fix the weed control fabric. When the weed control fabric needs to be covered, the operator holds the handle 6. The walking wheels 2 installed on the lower left and right sides of the mounting frame 1 allow the entire structure to move easily in the field. With the help of the handle 6, the operator does not need to carry it with great effort or operate it from the waist, which greatly saves the operator's physical strength and waist fatigue, improves the work efficiency of weed control fabric covering, and can quickly carry out weed control fabric covering operations in different planting areas.

[0024] The adjustment assembly includes a slide rod 7 fixed to the mounting bracket 1, a slider 8 slidably mounted on the upper side of the slide rod 7, a lead screw 9 rotatably connected to the mounting bracket 1 and threadedly connected to the slider 8, a crank handle 10 rotatably mounted on the right side of the mounting bracket 1 and driven by the lead screw 9, a connecting bracket 11 hinged vertically to the rear side of the slider 8, a circular hole 12 larger than the diameter of the rotating rod 3 is opened on the rear side of the connecting bracket 11, and a left baffle 4 rotatably connected to the left side of the connecting bracket 11.

[0025] When it is necessary to install the weed control fabric roll on the upper side of the rotating rod 3, insert the weed control fabric roll through the right side of the rotating rod 3. Then, the worker aligns the round hole 12 of the connecting frame 11 with the rotating rod 3 with one hand, and turns the crank handle 10 with the other hand. At this time, the right baffle 5 moves to the left and cooperates with the left baffle 4 to clamp the weed control fabric roll.

[0026] The adjustment assembly, through the cooperation of the crank handle 10, the lead screw 9 and the slider 8, allows the operator to easily move the right baffle 5 left and right by simply turning the crank handle 10, thereby fixing the weed control fabric roll to the rotating rod 3. This makes the adjustment method of the adjustment assembly simple and intuitive, and also allows the adjustment assembly to fix weed control fabric rolls of different widths, improving its applicability.

[0027] A friction disc 13 is fixedly installed on the left side of the left baffle 4, and an elastic telescopic rod 14 is fixedly installed on the left side of the mounting bracket 1. A friction block 15 matching the friction disc 13 is fixedly installed on the upper side of the telescopic end of the elastic telescopic rod 14.

[0028] The elastic telescopic rod 14 keeps the friction block 15 in contact with the friction disc 13 to generate frictional resistance, thereby preventing the rotating rod 3 and the upper fixed perforated weed control fabric from rotating on their own when they do not need to rotate, and from rotating excessively when laying and covering, thus ensuring the stability of the weed control fabric laying.

[0029] The right end of the rotating rod 3 has an arc-shaped guide angle of 16.

[0030] The curved guide angle 16 makes it easier to install the right baffle 5 and the connecting bracket 11 onto the upper side of the rotating rod 3, improving operational convenience.

[0031] The handrail 6 includes a main rod 17, which is fixedly connected to the mounting bracket 1. The front end of the main rod 17 has a retraction notch 18. A quick-release tube clamp 19 matching the retraction notch is installed on the outside of the main rod 17. A sub-rod is slidably assembled on the inside of the main rod 17. A rubber grip 21 is installed on the upper end of the sub-rod.

[0032] The sub-bar can slide back and forth within the mother bar 17 and is fixed by the quick-release tube clamp 19. This allows the operator to flexibly adjust the overall length of the handrail 6 according to their height and operating habits, making operation more comfortable and convenient while reducing the overall footprint when not in use. The rubber grip 21 can play a certain role in shock absorption, which helps to improve the grip comfort of the handrail 6.

[0033] Both the slide rod 7 and the lead screw 9 are fitted with telescopic protective sleeves 22.

[0034] The telescopic protective sleeve 22 can effectively prevent dust, dirt and other impurities from entering the gap between the slide rod 7 and the lead screw 9, ensuring the smooth operation of the adjustment component. At the same time, it also acts on the slide rod 7 and the lead screw 9, extending the service life of the components.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
