Description

Technical Field

[0001] This utility model belongs to the technical field of weeding equipment, specifically a soil loosening and weeding device between corn plants. Background Technology

[0002] Existing handheld weeding devices primarily rely on manual weeding with shovels, spades, or hoes. However, these tools have drawbacks: they require manual bending, resulting in high labor intensity. Furthermore, they can only remove individual weeds, leading to low efficiency, and they cannot simultaneously loosen the soil. While some existing rotary weeders can be operated standing up, their rotation is difficult to control, they have poor adaptability to plant spacing, and they easily entangle plants or miss weeds. This is especially problematic in cornfields where weeds have already grown to 30-50 cm tall, making precise weeding impossible. Most weeds grow in the gaps between adjacent rows, but some may grow between plants, making them difficult for many weeding tools to remove effectively, resulting in low weeding efficiency. Therefore, there is a need to design a device that allows weeding and soil loosening without bending over. Utility Model Content

[0003] To address the above technical problems, this utility model provides a device that allows weeding and loosening of soil without bending over, thus solving the problems of existing devices requiring bending over to weed and being unable to remove weeds between plants.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a corn interplant loosening and weeding device, comprising a long handle, a U-shaped handle hinged to the upper end of the long handle via a first hinge shaft, and a support base fixedly connected to the lower end of the long handle, a sliding sleeve sleeved on the outside of the long handle, a connecting rod hinged to the lower end of the U-shaped handle via a second hinge shaft, the lower end of the connecting rod hinged to the upper end of the sliding sleeve via a third hinge shaft, short rods hinged to both sides of the lower end of the sliding sleeve, the other end of the short rods hinged to the upper end of the long rod via a fourth hinge shaft, protrusions fixedly connected to both sides of the support base, ear plates fixedly connected to the outer ends of the protrusions, ear plates fixedly connected to the middle of the long rod via a fifth hinge shaft, a shovel head fixedly connected to the bottom of the long rod, a fixing plate fixedly connected to the bottom of the protrusions, a wheel rotatably connected between the two fixing plates, a handle fixedly connected to the upper end of the long handle, and a hoe fixedly connected to one side of the support base.

[0005] Furthermore, one end of the U-shaped handle opening is the lower end, and one side of its lower end is hinged to the connecting rod through the second hinge shaft.

[0006] Furthermore, the wheel surface is configured as an arc-shaped blade.

[0007] Furthermore, support rods are fixedly connected to both sides of the upper end of the long handle at an angle, and the other ends of the two support rods are fixedly connected to the handle.

[0008] Furthermore, a connecting frame is fixedly connected to the rear side of the support base, and a hoe is fixedly connected to the other end of the connecting frame. The hoe is designed to be semi-circular.

[0009] This utility model has the following advantages compared with the prior art:

[0010] 1. This utility model, by setting a shovel head with a U-shaped handle control device, can avoid people bending over to weed, reducing the intensity of manual labor. By setting the sharp end of the shovel head, weeds can be removed more easily. By setting a hoe, the soil can be loosened while weeding, and weeds in the empty rows can be completely eradicated, improving weeding efficiency.

[0011] 2. This utility model facilitates walking in the field by setting wheels, and by setting the surface of the wheels as arc-shaped blades, it can turn the soil in advance, making the use of the hoe easier. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 5The illustrated corn weeding and soil loosening device includes a long handle 1, which is a hollow or solid straight rod serving as the main support for the entire tool. The handle provides a lever arm for the operator to grip, allowing the user to work standing up and avoiding bending over. A U-shaped handle 2 is hinged to the upper end of the long handle 1 via a first hinge shaft 3. The U-shaped handle 2 is the user's main operating component; reciprocating movement of this handle provides power input to the entire tool. To provide support for the mechanism below, a support base 19 is fixedly connected to the lower end of the long handle 1. This base enables the sliding sleeve 7 to move up and down, thereby providing the opening and closing motion for the shovel head 10. A sliding sleeve 7 is fitted over the outside of the long handle 1. The dehumidification position of the sliding sleeve 7 is located in the lower middle part of the long handle 1, so that the shovel head 10 can be horizontally outward. In order to convert the rotational motion of the U-shaped handle 2 into linear motion, the crank-slider mechanism principle is used. The lower end of the U-shaped handle 2 is hinged to a connecting rod 5 through the second hinge shaft 4. The lower end of the connecting rod 5 is hinged to the upper end of the sliding sleeve 7 through the third hinge shaft 6, which can realize the up and down movement of the sliding sleeve 7. In order to convert the up and down movement of the sliding sleeve 7 into the opening and closing movement of the shovel head 10, short rods 8 are hinged to both sides of the lower end of the sliding sleeve 7. The other end of the short rods 8 is connected to the fourth hinge shaft 20. The upper end of the long rod 9 is hinged. To facilitate the support of the ear plate 13 and the fixed plate 11, protrusions 14 are fixedly connected to both sides of the support base 19. The ear plate 13 is fixedly connected to the outer end of the protrusion 14. In order to ensure that the long rod 9 can rotate around the ear plate 13 and realize the opening and closing of the shovel head, the ear plate 13 is fixedly connected to the middle of the long rod 9 through the fifth hinge shaft 21. The bottom of the long rod 9 is fixedly connected to the shovel head 10. The head of the shovel head 10 is sharpened and has a certain curvature. The specific curvature can be adjusted according to the specific design. It will not be described in detail here. It is only necessary to ensure that the head of the shovel head 10 contacts the ground when it reaches the lowest point, so as to ensure that each Every time weeds are shoveled, a fixed plate 11 is fixedly connected to the bottom of the protrusion 14 to support the rotation of the wheel 12. The wheel 12 is rotatably connected between the two fixed plates 11 through corresponding bearings. To avoid bending over and save effort, a handle 18 is fixedly connected to the upper end of the long handle 1. The two ends of the handle 18 are extended to make it easy for people to grip. In order to turn the soil and remove weeds at the same time, especially to remove weeds on the empty rows of corn, a hoe 16 is fixedly connected to one side of the support seat 19. The hoe 16 is set at a certain angle and is higher than the wheel 12. When weeding, pressing down the handle 18 will bring the hoe 16 into contact with the soil to turn the soil and remove weeds.

[0020] In order to make it easier to remove weeds between plants without bending over and with less effort, one end of the U-shaped handle 2 is the lower end, and one side of the lower end is hinged to the connecting rod 5 through the second hinge shaft 4.

[0021] In order to loosen the soil in advance, the surface of the wheel 12 is set with an arc blade. The wheel 12 rolls and loosens the soil first, and then the hoe 16 makes it easier to loosen the soil and remove weeds.

[0022] To make it easier to move and less strenuous, support rods 17 are fixedly connected to the upper two sides of the long handle 1 at an angle, and the other ends of the two support rods 17 are fixedly connected to the handle 18.

[0023] In order to loosen the soil and remove weeds at the same time, a connecting frame 15 is fixedly connected to the rear side of the support base 19, and a hoe 16 is fixedly connected to the other end of the connecting frame 15. The hoe 16 is designed to be semi-circular, so that the hoe 16 can be used more easily.

[0024] The specific working process of this utility model is as follows:

[0025] When the corn grows to a height of 30-50 cm after planting, weeds also begin to grow, mainly in the empty rows, and some between the plants. At this time, place this device in an empty row, hold the handle 18 and press down, so that the person's body forms a certain angle with the long handle 1. At this time, the hoe head 16 is in close contact with the ground, and the person can push the device forward. The wheels 12 in front dig up the soil, and the hoe head behind then turns the soil and removes weeds in one operation. When encountering weeds between the plants, aim the shovel head 10 at the weeds. Pull the U-shaped handle 2 backward. At this time, the lower end of the U-shaped handle 2 rises, which drives the connecting rod 5 to rise. The lower end of the connecting rod 5 drives the sliding sleeve 7 to slide upward along the long handle 1. At this time, the sliding sleeve 7 drives the upper end of the short rod 8 to move upward, and the lower end of the short rod 8 moves to the left, which drives the long rod 9 to rotate around the fifth hinge axis 21. The shovel head 10 at the lower end of the long rod 9 opens outward, which can remove weeds between plants, while protecting the plants from being accidentally damaged, thus improving weeding efficiency. Following the above steps can avoid bending over and speed up weeding efficiency, reducing the intensity of manual labor.
