Description

Technical Field

[0001] This utility model relates to the agricultural field, specifically to a fixed-distance ditching device for agricultural planting. Background Technology

[0002] In existing agricultural planting fields, in order to more easily adjust the lateral spacing between seeds, some furrowing devices are usually used to pre-space furrows, such as in garlic planting. After the furrows are dug, the seeds are planted in the furrows, which makes it easier to adjust the spacing between seeds and also makes it easier for the seeds to be buried in the ground.

[0003] To facilitate the adjustment of the furrowing spacing of the furrowing device, the manual furrowing machine is usually divided into two parts: an I-shaped pull rod and a plow head. One end of the I-shaped pull rod is a hand-held lever that is pulled manually, while the other end is a tension rod that fixes the plow head. The plow head is usually welded to a bushing that fits onto the tension rod. The tension rod is generally rectangular in structure to ensure that the bushing above the plow head does not rotate around the tension rod when the hand-held lever is pulled.

[0004] The plowshare spacing adjustment in this structure relies entirely on manual adjustment. After the screw passes through the bushing and is pressed tightly against the tension rod, the plowshare will inevitably shift to the left or right due to the vibration generated by the human body pulling it, thus affecting the spacing accuracy during subsequent use. Utility Model Content

[0005] The technical problem this invention aims to solve is that the plow head of existing fixed-distance furrowing devices for agricultural planting cannot guarantee that its position will not change during use.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a fixed-distance ditching device for agricultural planting, comprising an adjustable manual hook machine consisting of an I-shaped tie rod and a plow head sleeved on one side of the I-shaped tie rod. The I-shaped tie rod includes a tension rod connected to the plow head and a hand-held handle for easy gripping. Above the plow head of the plow head is a straight toothed block connected by a right-angle steel bar. The straight toothed block and the right-angle steel bar pass through the front side of the tension rod, and the toothed direction of the straight toothed block is downward.

[0007] The bottom surface of the cavity of the tension rod is provided with a positioning rack that meshes with the rack block. The top end of the rack block is provided with a positioning screw located inside the cavity of the tension rod. The positioning screw passes through the bottom surface of the rack block, and an internal hex wrench hole for easy rotation of the positioning screw is welded above the positioning screw. The top surface of the tension rod is provided with several equally spaced internal hex wrench hole slots.

[0008] As an improvement, the height of the convex cavity of the tension rod is greater than the sum of the tooth height of the straight rack block and the height of the positioning screw fixing plate.

[0009] As an improvement, the left and right sides of the tension rod are provided with sealing caps that close the tension rod cavity by means of bolts.

[0010] As an improvement, a baffle strip for fixing the counterweight bag is welded to the top surface of the tension rod.

[0011] As an improvement, several auxiliary connecting plates are welded to the connection end of the I-shaped tie rod and the tension rod.

[0012] As an improvement, the socket slot for the hexagonal wrench is a rectangular slot.

[0013] The advantages of this invention compared to the prior art are as follows: This device has a straight toothed block welded above the plowshare by right-angle steel bars. The straight toothed block meshes with the positioning rack on the bottom surface of the tension rod cavity, thereby ensuring that after the plowshare is locked in position, it can avoid left or right displacement due to manual pulling. After the plowshare is positioned, the positioning screw is rotated to make it press tightly against the top surface of the tension rod cavity, thereby ensuring the meshing state of the straight toothed block and the positioning rack.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] As per the instruction manual Figure 1 , 2As shown in Figures 3, 4, and 5, the existing manual furrowing machine 1 consists of an I-shaped tie rod 11 and a plow head 12 fitted onto one side of the I-shaped tie rod 11. The I-shaped tie rod 11 includes a tension rod 111 connected to the plow head 12 and a hand-held handle 112 for easy gripping. To ensure that the plow head 12 does not become loose after the spacing adjustment is completed, a straight toothed block 2 connected by a right-angle steel bar is provided above the plow head 12. The straight toothed block 2 and the right-angle steel bar pass through the front side of the tension rod 111, and the rack of the straight toothed block 2 faces downward. The bottom surface of the cavity of the tension rod 111 is provided with a connection to the straight toothed block. The positioning rack 21 engages with the straight rack block 2 to fix the position of the plow head 12. To ensure engagement between the positioning rack 21 and the straight rack block 2 during use, the top end of the straight rack block 2 is provided with a positioning screw 3 located inside the cavity of the tension rod 111. The positioning screw 3 passes through the bottom surface of the straight rack block 2. To ensure that the straight rack block 2 can be displaced in the cavity of the tension rod 111 after the positioning screw 3 is installed on the top surface of the straight rack block 2, the height of the convex cavity of the tension rod 111 is greater than the sum of the tooth height of the straight rack block 2 and the height of the fixing plate of the positioning screw 3.

[0022] To facilitate the rotation of the positioning screw 3, an internal hexagonal wrench hole 31 is welded on the top of the positioning screw 3. The top surface of the tension rod 111 is provided with several equidistant internal hexagonal wrench hole slots 32. In use, the internal hexagonal wrench is inserted into the internal hexagonal wrench hole 31 through these internal hexagonal wrench hole slots 32 for rotation. In order to ensure that the internal hexagonal wrench hole 31 can fit the internal hexagonal wrench hole slot 32, the internal hexagonal wrench hole slot 32 is a rectangular slot, thereby increasing the compatibility.

[0023] To prevent burrs from scratching fingers at the left and right openings of the tension rod 111 cavity during assembly, sealing caps 4 are provided on the left and right sides of the tension rod 111 to seal the cavity of the tension rod 111 through a bolt structure.

[0024] To ensure that the plow 12 can plow to a sufficient depth on hard ground, a counterweight bag is usually placed above the tension rod 111. The weight of the counterweight bag presses the plow 12 into the ground. To ensure the stability of the counterweight bag on the tension rod 111, a baffle strip 5 for fixing the counterweight bag is welded to the top surface of the tension rod 111. Similarly, to ensure the stability of the connection between the I-shaped tie rod 11 and the tension rod 111, several auxiliary connecting plates 6 are welded to the connection end of the I-shaped tie rod 11 and the tension rod 111. These auxiliary connecting plates 6 can also support the counterweight bag.

[0025] In the specific implementation of this utility model, the straight rack block 2 is slid into the cavity opening on one side of the tension rod 111. Before sliding in, the positioning screw 3 needs to be screwed into the screw hole on the top surface of the straight rack block 2. After fixing the position of each plow head 12, use an Allen wrench to pass through the Allen wrench hole slot 32 and insert it into the Allen wrench hole 31. Rotate the Allen wrench to unscrew the positioning screw 3 from the screw hole on the top surface of the straight rack block 2 until the head of the positioning screw 3 is tightly pressed against the top surface of the cavity of the tension rod 111. Through the positioning screw 3, the straight rack block 2 and the positioning rack 21 mesh with each other, thereby ensuring the position of the plow head 12.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
