Description

Technical Field

[0001] The utility model relates to the technical field of seed sowing, in particular to a seed sowing device. Background Art

[0002] Seed sowing is an agricultural activity that is often involved in the process of agricultural production. At present, seed sowing is mostly done by mechanical sowing, which involves sowing seeds through sowing tubes and then discharging them into the fields.

[0003] The existing announcement number is CN211792850U, which is a seed sowing and discharging device. This patent adopts the arrangement of a seed-shooting plate and a ball, so that the seeds splash outward under the elastic force of the seed-shooting plate, and most of the seeds hit the ball. Because the ball is a sphere, the seeds hit the ball at different positions, and the ejection angle and ejection force are different, and the seed ejection landing point is different. In this way, the sowing range is increased.

[0004] In daily work, the inventor found that although the above-mentioned seed sowing and discharging device can plant seeds in a straight line, the speed of seeds from the seeding box to the seeding tube is slow due to the lack of external force interference, and the seeding tube is easily blocked, thereby reducing the sowing efficiency of the device. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problems in the above background and to propose a seed metering device.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions: a seed sowing device, comprising a base, four pulleys fixedly mounted on the bottom surface of the base, two L-shaped plates fixedly mounted on the surface of the base, vertical grooves formed on the inner wall surfaces of the vertical ends of the two L-shaped plates, a slide slidably connected inside the vertical grooves, a horizontal strip fixedly mounted between the two slides, a seed box fixedly mounted on the side surfaces of the horizontal strips, a plurality of seed tubes fixedly mounted on the bottom surface of the seed box, support plates fixedly mounted on the side surfaces of the vertical ends of the two L-shaped plates, a rotating rod rotatably connected between the two supporting plates, a spring plate fixedly mounted on the outer wall surface of the rotating rod, a plurality of spring balls evenly fixedly mounted on the surface of the spring plate, an auxiliary device provided on the surface of the base, the auxiliary device comprising two sleeves fixedly mounted on the surface of the base, a push rod slidably connected inside the two sleeves, a long plate fixedly mounted on the end of the push rod away from the sleeve, and a plurality of lifting rods fixedly mounted on the surface of the long plate. The arrangement of the sleeves and push rods ensures the stable movement of the long plate.

[0007] Preferably, a vertical plate is fixedly mounted on the surface of the base, a motor is fixedly mounted on the surface of the vertical plate, and a cam is fixedly mounted on the output end of the motor. The arrangement of the motor plays an effect of driving the cam to rotate.

[0008] Preferably, two first springs are fixedly mounted on the surface of the long strip, and one end of the first spring away from the long strip is fixedly connected to the inner wall of the horizontal end of the L-shaped plate. The arrangement of the first springs has the effect of limiting the position of the horizontal strip.

[0009] Preferably, a limiting device is provided on the surface of one of the support plates, the limiting device comprising a groove, the groove being formed on the surface of one of the support plates, a displacement plate being slidably connected thereto, an insertion rod being fixedly mounted on the surface of the displacement plate, and a plurality of insertion holes being formed in an annular manner on the outer wall of the rotating rod. The provision of the insertion rod and the insertion holes serves to limit the rotation of the rotating rod.

[0010] Preferably, a circular plate is fixedly mounted on the surface of one of the support plates, and a second spring is fixedly mounted between the circular plate and the displacement plate. The second spring serves to limit the position of the displacement plate in the groove.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, an auxiliary device is provided. When the device needs to be used, the entire device is first moved to a suitable position, and then the motor is started. The motor starts to drive the cam to rotate, and the cam rotates to push the long plate upward. The long plate is pushed up and drives the push rod to move outward from the inside of the sleeve. At the same time, the long plate is pushed up and also drives the lifting rod to move upward. The upward movement of the lifting rod pushes the horizontal plate to move upward. The upward movement of the horizontal plate drives the slide plate to move upward inside the vertical slot. At the same time, the upward movement of the horizontal plate also squeezes the first spring, so that When the first spring is compressed, it also drives the seeding box to move upward. When the motor drives the cam to rotate and separates the cam and the long strip, the spring's rebound force will reset the seeding box. As the cam continues to rotate, the seeding box moves back and forth up and down. At this time, the seeds can be poured into the seeding box, and then the seeding box moves back and forth up and down. On the one hand, it will accelerate the seeds to enter the interior of the seeding tube, and on the other hand, it will avoid clogging of the seeding tube. Through the cooperation of the above structure, the seeding box can move back and forth up and down, thereby avoiding clogging of the seeding tube during seeding.

[0013] 2. In the utility model, by setting a limit device, when sowing is needed, the displacement plate can be slid first to move the displacement plate inside the groove. The movement of the displacement plate inside the groove will squeeze the second spring, so that the second spring is compressed. At the same time, the movement of the displacement plate inside the groove also drives the insertion rod to move. The movement of the insertion rod makes it move out of the inside of the socket. The insertion rod and the socket are separated, so that the rotating rod loses its limit. At this time, the spring plate can be rotated. When the spring plate is rotated to a suitable angle, the displacement plate is released, and the rebound force of the second spring is used to re-insert the insertion rod into the corresponding socket, so as to re-limit the rotation. The rod rotates and then pushes the entire device. At this time, the seeds inside the seed box will enter the inside of the seed tube, and then fall from the inside of the seed tube to the surface of the spring plate. At this time, the seeds splash outward under the elastic force of the spring plate, and most of the seeds hit the ball. Because the ball is a sphere, the seeds hit the ball at different parts, the ejection angle and ejection force are different, and the seed ejection landing point is different, completing the sowing operation. Through the cooperation of the above structure, the angle of the spring plate after adjustment is limited, thereby preventing the seeds from falling on the surface of the spring plate, causing the angle of the spring plate to change, thereby improving the ejection effect of the spring plate.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] See also Figure 1-4 The utility model provides a technical solution: a seed seeding device, comprising a base 1, four pulleys 4 are fixedly installed on the bottom surface of the base 1, two L-shaped plates 5 are fixedly installed on the surface of the base 1, and the inner wall surfaces of the vertical ends of the two L-shaped plates 5 are provided with vertical grooves 6, and a slide 7 is slidably connected inside the vertical groove 6, and a horizontal strip 8 is fixedly installed between the two slides 7. A seeding box 9 is fixedly installed on the side of the horizontal strip 8, and a plurality of seeding tubes 10 are fixedly installed on the bottom surface of the seeding box 9, and a support plate 11 is fixedly installed on the side of the vertical end of the two L-shaped plates 5, and a rotating rod 12 is rotatably connected between the two support plates 11, and a spring plate 13 is fixedly installed on the outer wall surface of the rotating rod 12, and a plurality of pinballs 14 are evenly fixedly installed on the surface of the spring plate 13.

[0023] The specific settings and functions of the auxiliary device 2 and the limiting device 3 are described in detail below.

[0024] In this embodiment: an auxiliary device 2 is provided on the surface of the base 1, and the auxiliary device 2 includes two sleeves 21, which are fixedly installed on the surface of the base 1. The interiors of the two sleeves 21 are slidably connected with push rods 22, and a long strip 23 is fixedly installed on the end of the push rod 22 away from the sleeve 21, and a plurality of lifting rods 24 are fixedly installed on the surface of the long strip 23.

[0025] In this embodiment, the arrangement of the sleeve 21 and the push rod 22 enables the long board 23 to move stably.

[0026] Specifically, a vertical plate 25 is fixedly mounted on the surface of the base 1 , a motor 26 is fixedly mounted on the surface of the vertical plate 25 , and a cam 27 is fixedly mounted on the output end of the motor 26 .

[0027] In this embodiment, the motor 26 is provided to drive the cam 27 to rotate.

[0028] Specifically, two first springs 28 are fixedly mounted on the surface of the long plate 23. The end of the first spring 28 away from the long plate 23 is fixedly connected to the inner wall of the horizontal end of the L-shaped plate 5. The arrangement of the first spring 28 has the effect of limiting the position of the horizontal plate 8.

[0029] In this embodiment, a limiting device 3 is provided on the surface of one of the support plates 11. The limiting device 3 includes a groove 31. The groove 31 is opened on the surface of one of the support plates 11. A displacement plate 32 is slidably connected to the inside of the groove 31. A plug rod 33 is fixedly installed on the surface of the displacement plate 32. A plurality of insertion holes 34 are formed in an annular shape on the outer wall surface of the rotating rod 12. When sowing is required, the displacement plate 32 can be slid first to move the displacement plate 32 inside the groove 31. The movement of the displacement plate 32 inside the groove 31 will squeeze the second spring 36, causing the second spring 36 to be compressed. At the same time, the movement of the displacement plate 32 inside the groove 31 also drives the plug rod 33 to move. The plug rod 33 moves so that it moves out of the inside of the plug hole 34. The plug rod 33 and the plug hole 34 are separated, causing the rotating rod 12 to lose its limit. At this time, the spring plate 13 can be rotated. When the spring plate 13 is rotated to a suitable angle, the displacement plate 32 is released. The rebound force of the second spring 36 is used to re-insert the plug rod 33 into the corresponding plug hole 34, thereby re-limiting the rotating rod. 12 rotates, and then pushes the entire device. At this time, the seeds inside the seed box 9 will enter the inside of the seed tube 10, and then fall from the inside of the seed tube 10 to the surface of the spring plate 13. At this time, the seeds are splashed outward under the elastic force of the spring plate 13, and most of the seeds hit the ball 14. Because the ball 14 is a sphere, the seeds hit the ball 14 at different positions, the ejection angle and ejection force are different, and the landing point of the seed ejection is different, completing the sowing operation. Through the cooperation of the above structure, the angle of the spring plate 13 after adjustment is limited, thereby preventing the seeds from falling on the surface of the spring plate 13, causing the angle of the spring plate 13 to change, thereby improving the ejection effect of the spring plate 13.

[0030] Specifically, a circular plate 35 is fixedly mounted on the surface of one of the support plates 11 , and a second spring 36 is fixedly mounted between the circular plate 35 and the displacement plate 32 .

[0031] In this embodiment, the second spring 36 is provided to limit the position of the displacement plate 32 inside the groove 31 .

[0032] Working principle: By setting the auxiliary device 2, when the device needs to be used, first move the entire device to a suitable position, then start the motor 26, the motor 26 starts to drive the cam 27 to rotate, the cam 27 rotates to make itself push the long strip 23 upward, the long strip 23 is pushed up and drives the push rod 22 to move outward from the inside of the sleeve 21, and at the same time, the long strip 23 is pushed up and drives the lifting rod 24 to move upward, the lifting rod 24 moves upward to push the horizontal strip 8 to move upward, the horizontal strip 8 moves upward and drives the slide plate 7 to move upward inside the vertical slot 6, and at the same time, the horizontal strip 8 moves upward and squeezes the first spring 28, so that When the first spring 28 is compressed, it also drives the sowing box to move upward. When the motor 26 drives the cam 27 to rotate, the cam 27 and the long plate 23 are separated, the spring's rebound force will reset the seed box 9. As the cam 27 continues to rotate, the seed box 9 moves back and forth up and down. At this time, the seeds can be poured into the seed box 9, and then the seed box 9 moves back and forth up and down. On the one hand, it will accelerate the seeds to enter the interior of the seed tube 10, and on the other hand, it will avoid clogging of the seed tube 10. Through the cooperation of the above structure, the seed box 9 can move back and forth up and down, thereby avoiding clogging of the seed tube 10 during seeding. When sowing is needed, the displacement plate 32 can be slid first to move the displacement plate 32 inside the groove 31. The movement of the displacement plate 32 inside the groove 31 will squeeze the second spring 36, so that the second spring 36 is compressed. At the same time, the movement of the displacement plate 32 inside the groove 31 also drives the insertion rod 33 to move. The insertion rod 33 moves to move itself out of the inside of the socket 34. The insertion rod 33 and the socket 34 are separated, so that the rotating rod 12 loses its limit. At this time, the spring plate 13 can be rotated. When the spring plate 13 is rotated to a suitable angle, the displacement plate 32 is released, and the rebound force of the second spring 36 is used to re-insert the insertion rod 33 into the corresponding socket 34, so as to re-limit the rotating rod. 12 rotates, and then pushes the entire device. At this time, the seeds inside the seed box 9 will enter the inside of the seed tube 10, and then fall from the inside of the seed tube 10 to the surface of the spring plate 13. At this time, the seeds are splashed outward under the elastic force of the spring plate 13, and most of the seeds hit the ball 14. Because the ball 14 is a sphere, the seeds hit the ball 14 at different positions, the ejection angle and ejection force are different, and the landing point of the seed ejection is different, completing the sowing operation. Through the cooperation of the above structure, the angle of the spring plate 13 after adjustment is limited, thereby preventing the seeds from falling on the surface of the spring plate 13, causing the angle of the spring plate 13 to change, thereby improving the ejection effect of the spring plate 13.
