Technical Field
[0001] This utility model relates to the field of millet sowing technology, and in particular to a millet sowing device. Background Technology
[0002] A grain planter is an agricultural machine used for planting cereal crops.
[0003] Currently, there is a type of grain planter on the market, which includes a frame and a grain storage box installed on the frame. When the moving wheels on the frame move, the grain storage box rotates synchronously under the drive of the linkage mechanism. When the material leakage hole on the grain storage box moves to the position of the feeding port, the material in the grain storage box will fall from the feeding port, thereby realizing the sowing of millet.
[0004] However, the above device has a drawback: after the first row of millet is sown, the device needs to be turned around. When the device is turned around, the wheels will still move the grain box, causing some millet to fall from the feeding port during the turning process, resulting in waste. Therefore, in order to avoid the waste caused by the grain falling during the turning process, this device is designed as a millet sowing device. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1
[0028] See attached document Figure 1-7 It should be noted that this patent is an improvement on the existing technology. The applicant mainly improved the equipment to address the waste caused by the continuous spillage of grain during the turning process, namely by adding a collection mechanism. For ease of understanding, the original mechanism of the equipment is partially described below. The structure other than the collection mechanism still adopts the existing technology.
[0029] The device includes: a frame 10, casters 101, a mounting frame 11, a pusher 12, a base 22, a grain storage box 20, a linkage assembly, and a collection mechanism. During sowing, pushing the pusher 12 moves the device. During the movement, the casters 101 drive the grain storage box 20 to rotate via the linkage assembly. When the discharge hole 21 on the grain storage box 20 moves to the position corresponding to the inlet 221, the grain in the grain storage box 20 falls from the discharge hole 21 into the inlet 221 and then onto the ground. During the turning process, the collection box 50 on the collection mechanism can be moved below the inlet 221. In this way, the grain falling from the inlet 221 during the turning process can be collected in the collection box 50, thus avoiding grain waste.
[0030] Specifically, the moving wheel 101 is rotatably mounted on the frame 10 via a pivot; the mounting frame 11 is mounted on the frame 10; the pusher frame 12 is mounted on the frame 10; the base 22 is fixedly mounted on the mounting frame 11, and the base 22 has a feeding port 221; the grain storage box 20 is rotatably mounted on the base 22, and the grain storage box 20 has multiple leakage holes 21; the linkage component is mounted on the frame 10, and when the moving wheel 101 rotates, the moving wheel 101 drives the grain storage box 20 to rotate through the linkage component; the collection mechanism is movably mounted on the mounting frame 11, and the collection mechanism is used to temporarily collect the grains that fall into the feeding port 221.
[0031] In one embodiment of this utility model, the linkage assembly includes a rotating rod 23, a driven bevel gear 24, a driving bevel gear 25, a transmission shaft 26, and a chain 27. The rotating rod 23 is fixedly installed on the bottom wall axis of the grain storage box 20. The driven bevel gear 24 is fixedly installed on the bottom end wall of the rotating rod 23. The transmission shaft 26 is rotatably installed on the mounting bracket 11. The driving bevel gear 25 is fixedly installed on one end wall of the transmission shaft 26, and the driving bevel gear 25 and the driven bevel gear 24 mesh with each other. The rotating shaft on one of the movable wheels 101 movably passes through the side wall of the frame 10 and extends to the outside of the frame 10. Sprockets are respectively installed on the end wall of the rotating shaft and the end wall of the transmission shaft 26 away from the driving bevel gear 25. The chain 27 is installed on the two sprockets. The principle of grain feeding is further explained here: When the moving wheel 101 rotates, the shaft on the moving wheel 101 near the push frame 12 drives the sprocket on it to rotate. The sprocket on the shaft drives the chain 27 to rotate. The chain 27 drives the sprocket on the drive shaft 26 to rotate. The sprocket on the drive shaft 26 drives the drive shaft 26 to rotate. The drive shaft 26 drives the driving bevel gear 25 to rotate. The driving bevel gear 25 meshes with the driven bevel gear 24, thereby driving the driven bevel gear 24 to rotate. The driven bevel gear 24 drives the rotating rod 23 to rotate. The rotating rod 23 drives the grain storage box 20 to rotate. After the grain storage box 20 rotates, the discharge hole 21 moves above the feeding port 221, so that the grain falls from the discharge hole 21 and the feeding port 221.
[0032] In one embodiment of this utility model, the collecting mechanism includes a collecting box 50, a slide rail 501, a connecting rod 51, a push handle 52, and a limiting box 53. The slide rail 501 is fixedly installed on the mounting frame 11. The collecting box 50 is slidably connected to the slide rail 501. The connecting rod 51 is installed on the outer wall of the collecting box 50. The push handle 52 is installed on the outer wall of the connecting rod 51. The limiting box 53 is fixedly installed on the side wall of the mounting frame 11, and the connecting rod 51 is slidably connected to the limiting box 53. When turning, the collecting mechanism can temporarily collect grains that have fallen into the inlet 221. The specific principle is as follows: when turning is required, the push handle 52 can be pulled, the push handle 52 drives the connecting rod 51 to move, and the connecting rod 51 drives the collecting box 50 to move, so that the collecting box 50 moves to below the inlet 221. In this way, when grains fall into the inlet 221, the grains can be collected into the collecting box 50.
[0033] In one embodiment of the present invention, a movable box 54 is placed inside the collection box 50; wherein, in order to facilitate the removal of grains from the collection mechanism, a movable box 54 is placed inside the collection box 50, and the movable box 54 can be removed from the collection box 50.
[0034] In one embodiment of this utility model, a limiting groove 55 is provided on the side wall of the push handle 52, and a limiting rod 56 is fixedly installed on the outer wall of the push frame 12. The limiting rod 56 passes through the inside of the limiting groove 55. The limiting groove 55 and the limiting rod 56 are provided to limit the distance the push handle 52 can move. When the limiting rod 56 is at the two ends of the limiting groove 55, the collection box 50 is completely removed from the mounting frame 11 or is directly below the dispensing port 221.
[0035] In one embodiment of this utility model, a fixing plate 57 is fixedly installed on the outer wall of the pusher 12, and a threaded push rod 58 is threadedly installed on the outer wall of the fixing plate 57. The threaded push rod 58 is used to press and fix the push handle 52. During the turning process, the threaded push rod 58 can be rotated so that the bottom end of the threaded push rod 58 presses against the outer wall of the push handle 52, thereby locking and fixing the position of the push handle 52. By fixing the position of the collection box 50, the collection box 50 is prevented from sliding randomly during the turning process.
[0036] In one embodiment of this utility model, two digging cutter discs 30 and two covering cutter discs 40 are rotatably mounted on the frame 10. The two digging cutter discs 30 and the two covering cutter discs 40 are arranged in a figure-eight shape facing each other. When sowing grain, the two digging cutter discs 30 first open the ground. That is, when the device moves, the digging cutter discs 30 are close to the ground, thereby opening the planting trough. The grain in the feeding port 221 can fall into the planting trough. As the device moves, the covering cutter discs 40 are behind the feeding port 221. During the movement, the soil dug by the digging cutter discs 30 can be re-covered.
[0037] In this embodiment, the working principle of the device is as follows: During the sowing operation, the push frame 12 is pushed to move the entire device. During the movement, the moving wheel 101 rotates through the rotating shaft. The rotating shaft of one of the moving wheels 101 drives the sprocket on its end wall to rotate. The sprocket drives the sprocket at the other end of the transmission shaft 26 to rotate through the chain 27, thereby causing the transmission shaft 26 to rotate. When the transmission shaft 26 rotates, the driving bevel gear 25 at one end of it rotates accordingly. Since the driving bevel gear 25 meshes with the driven bevel gear 24, the driven bevel gear 24 drives the rotating rod 23 to rotate, ultimately causing the grain storage box 20 to rotate on the base 22.
[0038] When the discharge hole 21 on the grain storage box 20 is rotated to the position corresponding to the feeding port 221 on the base 22, the millet in the grain storage box 20 falls from the discharge hole 21 into the feeding port 221 and then falls to the ground through the feeding port 221 to complete the sowing; at the same time, during the movement of the device, the two digging blades 30, which are arranged in a figure-eight shape opposite each other, first dig trenches on the ground to form planting troughs, and the millet falls into the planting troughs. Then, the two covering blades 40 cover the millet with the soil that has been dug up.
[0039] When it is necessary to change direction, pull the push handle 52. The push handle 52 drives the connecting rod 51 to move. The connecting rod 51 slides in the limit box 53, and at the same time drives the collection box 50 to slide on the slide rail 501 until the collection box 50 moves directly below the delivery port 221.
[0040] At this time, rotate the threaded push rod 58 to press against the push handle 52 and fix the position of the collection box 50; during the reversal process, the millet falling from the inlet 221 will fall into the movable box 54 inside the collection box 50 to achieve temporary collection of the millet and avoid waste.
[0041] After the direction is reversed, rotate the threaded push rod 58 in the opposite direction to release the fixation of the push handle 52, push the push handle 52 to reset the collection box 50, and the sowing operation can continue. When there is a lot of millet collected in the movable box 54, it can be taken out from the collection box 50 so that the collected millet can be reused.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
