DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 6As shown, a corn planting and fertilizing device described in an embodiment of the utility model comprises a frame 1; a fixing frame 11 is fixedly connected to the inner side wall of the frame 1; a feeding trough 12 is fixedly connected to the inside of the fixing frame 11; a first driving motor 13 is fixedly connected to the side wall of the frame 1; a first rotating rod 14 is fixedly connected to the output end of the first driving motor 13; the first rotating rod 14 passes through the fixing frame 11 and the side wall of the feeding trough 12 and extends to the inside of the feeding trough 12; the first rotating rod 14 is rotatably connected to the fixing frame 11 and the feeding trough 12; a plurality of groups of feeding troughs 15 are fixedly connected to the middle part of the first rotating rod 14; a second driving motor 16 is fixedly connected to the side wall of the frame 1; a second rotating rod 17 is fixedly connected to the output end of the second driving motor 16; the second rotating rod 17 passes through the side wall of the frame 1 and is rotatably connected to the frame 1; a pair of gears are fixedly connected to the middle part of the second rotating rod 17 18; a pair of first connecting plates 19 are slidably connected to the inner side wall of the frame 1; a rack 22 is fixedly connected to the side wall of the first connecting plate 19; the rack 22 and the gear 18 are meshed with each other; a second connecting plate 20 is fixedly connected to the side wall of the first connecting plate 19; the second connecting plate 20 is located on the side wall of the first connecting plate 19 away from the gear 18; a pair of cutters 21 are installed at the ends of the second connecting plates 20. When working, by putting fertilizer into the feeding trough 12, by pushing the frame 1 and turning on the switch of the first drive motor 13, the first drive motor 13 drives the dividing trough 15 to rotate, and then the fertilizer inside the feeding trough 12 falls evenly in multiple sections into the grooves opened by the cutter 21, so as to realize the fertilization of corn seeds. When it is necessary to dig grooves of different depths, the switch of the second drive motor 16 is turned on. The second driving motor 16 drives the second rotating rod 17 to rotate, and then the gear 18 on the second rotating rod 17 rotates. The first connecting plate 19 is connected to the rack 22 and driven by the gear 18 to slide up and down, so that the connected tool 21 is moved up and down through the second connecting plate 20, and the height of the tool 21 is adjusted. When trenching, trenches of different depths can be dug, and corn seeds in different fields can be adaptively fertilized, thereby improving the quality of fertilization and the protection effect on corn seeds.

[0025] like Figures 1 to 4As shown, a pair of adjustment plates 3 are hingedly connected to the inner side wall of the feeding trough 12; an adjustment block 31 is fixedly connected to the bottom side wall of the adjustment plate 3; the adjustment block 31 is arranged in an arc shape; the adjustment block 31 passes through the wall of the feeding trough 12 and is slidably connected to the feeding trough 12; a plurality of groups of pin holes 32 are arranged in the middle of the adjustment block 31; a limit pin 33 is installed inside the pin hole 32; the limit pin 33 and the pin hole 32 are slidably matched; a reset torsion spring is installed at the hinge of the adjustment plate 3 and the feeding trough 12. When working, when the feeding trough 12 is used for fertilizing, it is necessary to first pull the adjustment block 31 to move the mutually closed adjustment plates 3 toward the feeding trough 12, and then insert the limit pin 33 into the corresponding pin hole 32 The adjusting plate 3 is limited in position so that the adjusting plate 3 will not rebound. When different amounts of fertilizer are needed, the distance between the pair of adjusting plates 3 is adjusted by moving the position of the adjusting block 31. After the position of the adjusting plate 3 is adjusted, the limiting pin 33 is inserted into the corresponding pin hole 32 again so that the falling speed of the fertilizer is affected by the distance between the adjusting plates 3, thereby adjusting the feeding speed of the fertilizer. This can adapt to the amount of fertilizer required for different purposes, thereby increasing the adaptability of the fertilization effect of the device. At the same time, when the feeding trough 12 is not in use, the pair of adjusting plates 3 are used to protect it, thereby reducing the dust and impurities from falling into the dividing trough 15, thereby causing pollution and corrosion to the dividing trough 15, thereby improving the protection effect of the dividing trough 15.

[0026] like Figure 1 and Figure 5 As shown, a plurality of screw holes 41 are provided on the side wall of the second connecting plate 20; a bolt 4 is installed between the tool 21 and the screw hole 41; the bolt 4 passes through the side wall of the tool 21 and is threadedly connected to the screw hole 41. During operation, when it is necessary to excavate grooves of different widths, the bolt 4 is separated from the screw hole 41 by rotating the bolt 4, thereby disassembling the second connecting plate 20 and the tool 21. By replacing tools 21 of different sizes and then installing and fixing the tool 21 and the second connecting plate 20 by matching the bolt 4 and the screw hole 41, the size of the groove can be controlled during the groove excavation, thereby increasing the adaptability of the device.

[0027] like Figure 4 As shown, an anti-skid pad 5 is fixedly connected to the pin hole 32; the anti-skid pad 5 is made of rubber material. During operation, by arranging the anti-skid pad 5 inside the pin hole 32, when the limit pin 33 is inserted into the pin hole 32, the anti-skid pad 5 increases the friction force on the limit pin 33, reduces the possibility of the limit pin 33 slipping out of the pin hole 32, improves the stability of the limit pin 33 when fixing the adjustment plate 3, and increases the safety during fertilization.

[0028] like Figure 6As shown, the side wall of the first connecting plate 19 is embedded with multiple groups of balls 7; the balls 7 are symmetrically arranged on the first connecting plate 19; the first connecting plate 19 and the frame 1 are in rolling cooperation. When working, by arranging the balls 7 between the first connecting plate 19 and the frame 1, part of the sliding friction between the frame 1 and the first connecting plate 19 can be converted into rolling friction, thereby reducing the friction loss between the first connecting plate 19 and the frame 1 and improving the service life of the first connecting plate 19 and the frame 1.

[0029] like Figure 2 As shown, a plurality of groups of fixing rods 6 are fixedly connected to the top of the fixing frame 11; the fixing rods 6 are symmetrically arranged on the fixing frame 11; the ends of the fixing rods 6 are fixedly connected to the side walls of the feeding trough 12; the fixing rods 6 are inclinedly arranged. When working, by arranging a plurality of fixing rods 6 between the feeding trough 12 and the fixing frame 11, the fixing rods 6 can support the feeding trough 12, thereby reducing the problem of the feeding trough 12 being tilted due to excessive force caused by too much fertilizer being put into the feeding trough 12 at one time, thereby improving the safety during the fertilization process.

[0030] During operation, fertilizer is put into the feeding trough 12, and the switch of the first driving motor 13 is turned on while pushing the frame 1, so that the first driving motor 13 drives the dividing trough 15 to rotate, and then the fertilizer inside the feeding trough 12 falls evenly into the grooves plowed by the cutter 21 in multiple sections, thereby fertilizing the corn seeds. When grooves of different depths need to be dug, the switch of the second driving motor 16 is turned on. The second driving motor 16 drives the second rotating rod 17 to rotate, thereby rotating the gear 18 located on the second rotating rod 17. The first connecting plate 19 is connected to the rack 22 and is driven by the gear 18 to slide up and down, thereby causing the tool 21 connected through the second connecting plate 20 to move up and down, thereby adjusting the height of the tool 21. When using the feeding trough 12 to apply fertilizer, it is necessary to first pull the adjusting block 31 to move the mutually closed adjusting plates 3 toward the feeding trough 12, and then insert the limit pin 33 into the corresponding pin hole 32 to limit the adjusting plate 3 so that the adjusting plate 3 will not rebound. When different amounts of fertilizer are required, the distance between the pair of adjusting plates 3 is adjusted by moving the position of the adjusting block 31. After adjusting the position of the adjusting plate 3, the limit pin 33 is inserted into the corresponding pin hole 32 again so that the falling speed of the fertilizer is affected by the distance between the adjusting plates 3. The screw hole 41 is used to make the second connecting plate 20 and the cutter 21 be disassembled, and the cutter 21 is installed and fixed to the second connecting plate 20 by replacing the cutter 21 of different sizes. The anti-skid pad 5 is provided inside the pin hole 32. When the limit pin 33 is inserted into the pin hole 32, the anti-skid pad 5 increases the friction force on the limit pin 33, thereby reducing the possibility of the limit pin 33 slipping out of the pin hole 32. The ball bearing 7 is provided between the first connecting plate 19 and the frame 1, so that part of the sliding friction between the frame 1 and the first connecting plate 19 can be converted into rolling friction, thereby reducing the friction loss between the first connecting plate 19 and the frame 1. The plurality of fixing rods 6 are provided between the feeding trough 12 and the fixing frame 11, so that the fixing rods 6 can support the feeding trough 12.
