Description

A kind of hardware accessories for loosening soil and weeding

technical field

The invention relates to the technical field of hardware accessories, in particular to a dual-purpose hardware accessory for loosening soil and weeding.

Background technique

Hardware accessories refer to machine parts or components made of hardware, as well as some small hardware products, which can be used alone or as auxiliary appliances. In modern life, people prefer houses with courtyards, and communicate with nature through courtyards. No matter the size of the courtyard, it is a place where you can display your design talents. Even if it is five or six square meters, the owner of the courtyard can dress it up with a strange brilliance. The urban environment is suitable for large color blocks and generous strokes. Landscape, and small gardens should use small and exquisite techniques to express the characteristics of individuality, but the maintenance of the courtyard is very labor-intensive, and the most time-consuming and laborious work is regular weeding and soil loosening planting. Although there are many Automatic weeding and loosening device, however, automated machinery is expensive and bulky. Generally, it is used for park gardening. In small private courtyards, people use hardware accessories such as small hoes and small nail rakes for weeding and loosening operations. , but the efficiency is low and it is inconvenient to operate, so it is very necessary to invent a hardware accessory that can be used for loosening soil and weeding to help people improve the efficiency of gardening.

SUMMARY OF THE INVENTION

Therefore, in order to solve the above deficiencies, the present invention provides a dual-purpose hardware accessory for soil loosening and weeding, which has the advantages of both soil loosening and weeding functions, and can effectively improve the efficiency of people's gardening.

The present invention is realized by constructing a dual-purpose hardware accessory for loosening and weeding, including a frame rod, a loosening and weeding piece and a linkage. The frame rod is a short hollow rod with a diameter of 35 mm, and the end of the frame rod is provided with a loosening and weeding piece The opening a is connected, and the adjacent side of the opening a of the loosening and weeding piece is connected with a movable groove at the end of the linkage; It includes a connection area and an operation area. The connection area and the operation area are integrated. The connection area is specifically two flat metal plates with a spacing of 43mm. There is a frame rod connection opening a at the bottom of the working area; the working area is set at the bottom of the connecting area, the working area is a triangular bent metal plate with an open top, and both ends of the side of the working area have cutting edges; the linkage is the middle part The 180° bent metal sheet has a chamfering treatment on the bending part, and the chamfering radius is 20mm. , the bending end of the linkage is provided with a connection opening b for the loosening and weeding piece, and the opposite side of the connecting hole b for the loosening and weeding piece is provided with a connecting hole b for a frame rod; , the soil ripper and weeding member and the frame rod are connected with the linkage member through connecting rod bolts, and the connecting rod bolt on the frame rod connecting hole b runs through the movable groove at the end of the linkage member, and the movable groove at the end of the linkage member can move linearly in translation. The diameter specifications of the above connecting rod bolts are all 6mm.

Further, the connection area of the loosening and weeding piece, the linkage piece and the frame rod are connected to form a movable triangular structure. The hardware accessories are assembled on a long pole or used directly. The working area is against the ground. During use, the loosening and weeding parts rub against the ground during the forward push process, and according to the spacing specifications of each connection hole, they are vertical at right angles under the action of friction. Pull the end of the connecting hole of the frame rod of the top linkage to move forward in the movable groove at the end of the linkage, and the connecting rod bolt in the connecting hole of the frame rod is pressed against the front end of the movable groove at the end of the linkage and is limited to loosen the soil. When the weeding piece is active, the front edge of the working area on the loosening and weeding piece is displaced in a flat push-like manner, cutting off the surface weeds and realizing fast weeding.

Further, the slotted length of the movable slot at the end of the linkage is 38mm. When in use, the loosening and weeding piece rubs against the ground again during the back-pulling process, and under the action of the friction force, it tilts backward, and pushes the linkage piece obliquely backward. , the connecting rod bolts in the connection openings of the frame rods are pressed against the rear end of the movable groove at the end of the linkage and limit the movement of the loosening and weeding parts. When the rear edge of the working area of the ripper and weeding element is inclined at an obtuse angle and then scrapes away, the surface soil is shoveled up. Through continuous and rapid forward and backward pulling actions, weeding and soil loosing can be quickly carried out, which can effectively improve people's care. Yard Efficiency.

Further, the distance between the connection opening a of the loosening and weeding member and the movable groove at the end of the linkage member is 120 mm. The frame rod is movably connected to the loosening and weeding piece by connecting rod screws through the set connection opening a of the weeding piece.

Further, the distance between the connecting hole of the linkage member and the connecting hole a of the frame rod is 47 mm. The linkage is movably connected to the loosening and weeding element by connecting rod bolts through the provided connecting opening a of the linkage.

Further, the distance between the connection opening b of the loosening and weeding piece and the connection opening of the frame rod is 130 mm. Positioning is performed through the connection opening b of the loosening and weeding piece and the connection opening of the linkage piece.

Further, the cutting edge is a large flat grinding edge with an acute angle of 23°. Weeding and loosening are carried out with the set cutting edge.

Further, the bending part of the working area and the transition area between the working area and the connection area are all chamfered, and the chamfering treatment eliminates the problem of stress concentration at the bend.

The present invention provides a dual-purpose hardware accessory for soil loosening and weeding through improvement. Compared with the existing dual-purpose hardware accessory for soil loosening and weeding, the present invention has the following advantages: it has both soil loosening and weeding functions, and can effectively improve the efficiency of people in gardening.
