Description

Technical Field

[0001] The utility model relates to the technical field of seed drills, in particular to a drum type seed drill. Background Art

[0002] The structure of the existing drum seeder is mostly to fix the working rod for installing the seeding wheel on the frame. In order to improve the seeding efficiency, multiple seeding wheels are often arranged side by side. When the frame moves, it drives several seeding wheels to rotate synchronously so as to sow multiple rows at the same time. The problem is that when the land is not flat enough, the raised area will lift up the corresponding seeding wheel, causing the seeding wheel in contact with the raised land to rotate normally and sow, while the land in other places is relatively low, causing the corresponding seeding wheel to be separated from the ground, and the seeding wheel cannot rotate normally, so it cannot be sown normally, which eventually leads to the phenomenon of missing seeds, and artificial seedlings will be needed later.

The seeding wheel 22 belongs to the prior art in this field.

[0024] In the above-mentioned drum seeder, when the seeding wheel 22 installed on a certain working rod 13 walks on the raised ground, the seeding wheel 22 is lifted up, so that the working rod 13 rotates around the upper end, and the first spring 12 is compressed to provide a certain downward pressure on the working rod 13, which can prevent the seeding wheel 22 from leaving the ground under the action of inertia, so that the seeding wheel 22 always fits the ground and avoids the phenomenon of missing seeds. Each working rod 13 and seeding wheel 22 are equipped with a fixing frame 10, a fixing plate 11 and a first spring 12, so that each seeding wheel 22 can always fit the ground and achieve normal rotation and normal seeding even if the ground is uneven.

[0025] Specifically, in order to facilitate the adjustment of the planting row spacing, the upper end of the working rod 13 is hinged on the first sliding sleeve 9; the fixing frame 10 is fixedly mounted on the upper end of the second sliding sleeve 17; the first sliding sleeve 9 and the second sliding sleeve 17 can be slidably mounted on the mounting frame, and the locking screw 16 passes through the first sliding sleeve 9 and the second sliding sleeve 17 and abuts against the mounting frame. Loosen all the locking screws 16, drag the two adjacent groups of the first sliding sleeve 9 and the second sliding sleeve 17 to move until the target row spacing is reached, tighten the locking screws 16, lock the positions of the first sliding sleeve 9 and the second sliding sleeve 17, and adjust the spacing between the two adjacent seeding wheels 22, thereby achieving the adjustment of the row spacing.

[0026] Specifically, in order to increase the adjustment range of row spacing, both sides of the mounting frame can be pulled out and installed with a pull-out frame 8; the locking screw 16 passes through the mounting frame and abuts against the pull-out frame 8; the first sliding sleeve 9 and the second sliding sleeve 17 can be slidably installed on the pull-out frame 8; the upper end of the second sliding sleeve 17 is fixedly installed with a "U"-shaped fixing frame 10; the upper end of the working rod 13 is hinged to the first sliding sleeve 9, and the other end passes through the fixing frame 10. When the existing working width cannot meet the requirements, loosen the locking screws 16 connecting the pull-out frame 8 and the mounting frame, pull out the pull-out frames 8 on both sides, and tighten the locking screws 16 to lock the position of the pull-out frame 8. Then adjust the position of the pull-out frame 8 and the first sliding sleeve 9 and the second sliding sleeve 17 on the mounting frame, so as to adjust the distance between the adjacent working rods 13 and the seeding wheel 22, and complete the adjustment of the row spacing.

[0027] Specifically, the mounting frame includes a first cross bar 3, a second cross bar 4, a longitudinal bar 5, a third cross bar 6, and a fourth cross bar 7; the first cross bar 3 and the second cross bar 4 are fixedly connected by the longitudinal bar 5; the first cross bar 3 and the third cross bar 6 are fixedly connected at both ends, and a gap is left between the two for the first sliding sleeve 9 to move; the second cross bar 4 and the fourth cross bar 7 are fixedly connected at both ends, and a gap is left between the two for the second sliding sleeve 17 to move; the upper ends of the pull-out frames 8 on both sides are inserted into the first cross bar 3, and the other is inserted into the third cross bar 6; the lower ends of the pull-out frames 8 on both sides are inserted into the second cross bar 4, and the other is inserted into the fourth cross bar 7. The above-mentioned mounting frame has a simple structure, low cost, and low weight, and the upper and lower ends are designed as double rods, the upper end is a first cross bar 3 and a third cross bar 6 double rod, and the lower end is a second cross bar 4 and a fourth cross bar 7 double rod, and the pull-out frames 8 on both sides are respectively inserted into different cross bars. Compared with the upper and lower ends being set as a single rod, the pull-out frames on both sides are inserted into the same cross bar, which can effectively increase the pull-out distance of the pull-out frames 8 and increase the row spacing adjustment range.

[0028] Specifically, the two pull-out frames 8 have the same size.

[0029] Specifically, it also includes a frame 1, the top plate 102 of the frame 1 is hinged to the bottom of the mounting frame through a hinge shaft 2. The top plate 102 is rotatably connected to the longitudinal rod 5 of the mounting frame through the hinge shaft 2. The frame 1 is rotatably connected to the mounting frame, which can better adapt to the terrain.

[0030] Specifically, both ends of the side plates 101 on both sides of the frame 1 are fixed with support plates 14; the upper ends of the support plates 14 are fixed with second springs 15; the second springs 15 are located below the mounting frame. The second springs 15 can play a certain buffering role when the mounting frame swings around the hinge shaft 2.

[0031] Specifically, in order to reduce the weight of the frame 1 , a weight-reducing hole 103 is provided on the side plate 101 .

[0032] Specifically, the lower part of the working rod 13 is hinged with the U-shaped frame 18, and the lower end of the U-shaped frame 18 is fixedly connected with a support rod 19; the lower end of the support rod 19 is rotatably mounted with a wheel 20. When the U-shaped frame 18 rotates, the notches on both sides thereof can be used as limiters to limit the rotation angle of the U-shaped frame 18 and the support rod 19, so as to prevent the support rod 19 and the wheel 20 from hitting the seeding wheel 22 and the travel wheel installed on the frame 1 when rotating.

[0033] Specifically, the frame 1 is equipped with a handle 23, a running wheel, and a driving device 21 for driving the running wheel to rotate. When working, the handle 23 is held to control the direction, and the driving device 21 is turned on to drive the running wheel to rotate, thereby driving the entire device to move. The running wheel and the driving device belong to the prior art in this field.

[0034] The working principle of this utility model:

[0035] When the existing working width cannot meet the requirements, loosen the locking screws 16 connecting the pull-out frame 8 and the mounting frame, pull out the pull-out frames 8 on both sides, and tighten the locking screws 16 to lock the position of the pull-out frame 8. Loosen all the locking screws 16, drag the two adjacent sets of first sliding sleeves 9 and second sliding sleeves 17 to move until the target row spacing is reached, tighten the locking screws 16, lock the positions of the first sliding sleeves 9 and second sliding sleeves 17, and adjust the spacing between the two adjacent seeding wheels 22, thereby achieving the adjustment of the row spacing.

[0036] During sowing operations, when a sowing wheel 22 installed on a certain working rod 13 walks on a raised ground, the sowing wheel 22 is lifted up, so that the working rod 13 rotates around the upper end, and the first spring 12 is compressed to provide a certain downward pressure on the working rod 13, which can prevent the sowing wheel 22 from leaving the ground under the action of inertia, so that the sowing wheel 22 always fits the ground and avoids the phenomenon of missing seeds. Each working rod 13 and sowing wheel 22 are equipped with a fixing frame 10, a fixing plate 11 and a first spring 12, so that each sowing wheel 22 can always fit the ground and achieve normal rotation and normal sowing even if the ground is uneven.

[0037] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
