Description

Technical Field

[0001] The utility model belongs to the technical field of peanut planting, and in particular relates to a furrowing device. Background Art

[0002] Peanut planting trenching refers to digging trenches in the soil to provide a good growth environment for peanut crops. The following are the general steps for peanut planting trenching: soil preparation. After selecting the planting site, you first need to prepare the soil, clean up weeds and stones, and make the soil flat and soft. Trenching. Use appropriate agricultural tools to dig trenches in the soil. The spacing is usually about 50 cm, the trench depth is about 10 cm, and the trench width is 15-20 cm. During the trenching process, the tool needs to be replaced when it is used in the soil for a long time, otherwise it will affect the trenching quality. The tool moves slowly when encountering harder soil and requires greater thrust. The current tools are independently installed individuals distributed at intervals. When the tool needs to be disassembled for grinding or replacement, the tool needs to be disassembled one by one, which is inconvenient to replace. Therefore, the inventor proposes a trenching device to meet the use needs. Utility Model Content

[0023] This specific embodiment is a trenching device, and its structural schematic diagram is as follows Figure 1 , Figure 2 As shown, it includes a supporting base plate 1, a cross beam 2, a vertical pole 3 and a fixed plate 4. The supporting base plate 1 is horizontally arranged and has a through hole in the middle. The upper surface of the supporting base plate 1 is symmetrically installed with fixed plates 4 on both sides of the through hole. There are two groups of fixed plates 4, and the cross beam 2 is slidably installed between them. The vertical pole 3 is movably installed on the upper surface of the supporting base plate 1. The fixed plate 4 is vertically arranged and a lifting groove 5 is vertically opened inside. A lifting block 15 is slidably installed inside the lifting groove 5. The lifting blocks 15 are symmetrically distributed on both sides of the cross beam 2, and the lifting blocks 15 are fixedly connected to the cross beam 2. A hanging plate 10 is horizontally arranged below the cross beam 2. The bottom of the hanging plate 10 is detachably connected with a knife plate 12. The knife plate 12 is horizontally arranged and has a plurality of groups of grooving knives 13 distributed at intervals at the bottom.

[0024] Reference Figure 2 , Figure 3 The bottom end surface of the hanging plate 10 has a T-shaped slide groove, and the upper surface of the knife plate 12 is protruding with a T-shaped slider 11, which is adapted to the slide groove. A fixed tube 6 is vertically fixed on the upper surface of the hanging plate 10, and the fixed tube 6 corresponds to the position of the slider 11. The fixed tube 6 is slidably inserted into the interior of the fixed tube 6. The upper surface of the slider 11 has a positioning hole, and when the positioning hole corresponds to the fixed tube 6, the limiting rod 7 is vertically inserted.

[0025] Reference Figure 2 , Figure 4, a socket 9 is provided on the side wall of the fixed plate 4, and two groups of sockets 9 are arranged vertically at intervals. A limit pin 8 is slidably inserted inside the socket 9, and a limit hole 16 is provided on the side wall of the lifting block 15, and the limit pin 8 is adapted to be inserted into the limit hole 16. Two groups of vertically distributed connecting rods 14 are fixedly connected to the bottom of the beam 2, and one end of the connecting rod 14 away from the beam 2 is fixedly connected to the upper surface of the hanging plate 10. Insert the limit pin 8 into the socket 9 located below, and after the limit pin 8 and the lifting block 15 are fixed, the trenching knife 13 can be fixed, and the supporting bottom plate 1 is pushed so that the trenching knife 13 can move along the convex surface to trench.

[0026] Working principle: When in use, the support base plate 1 is moved by the vertical rod 3, and the bottom of the support base plate 1 has a sliding function. When the support base plate 1 is located on the trenching land, the limit pin 8 is pulled out. After the limit is lost, the lifting block 15 can slide down vertically along the lifting groove 5, and then the crossbeam 2 is lowered, and the hanging plate 10 and the knife plate 12 are driven to move downward through the connecting rod 14 until the trenching knife 13 extends into the soil, and then the limit pin 8 is inserted into the socket 9 located below. After the limit pin 8 is fixed with the lifting block 15 again, the trenching knife 13 can be fixed, and the support base plate 1 is pushed, so that the trenching knife 13 can move along the convex surface to trench;

[0027] When the trenching knife 13 needs to be replaced or sharpened to increase its sharpness, it is moved horizontally upward to a raised state, and the limit rod 7 is pulled out from the inside of the fixed tube 6. After the limit rod 7 is lost, the slider 11 can slide out along the slide groove at the bottom of the hanging plate 10, and the limit rod 7 is fixedly connected to the upper surface of the slider 11, so that the knife plate 12 can be moved out from the bottom of the hanging plate 10 as a whole and can be directly replaced as a whole. The old trenching knife 13 only needs to wait for subsequent maintenance, and the supporting base plate 1 can be used again, saving replacement procedures and improving trenching quality.
