Description

Technical Field

[0001] This utility model relates to the field of seeding device technology, and in particular to a quantitative seed taking and sowing device. Background Technology

[0002] Astragalus and Scutellaria are both common Chinese medicinal herbs, widely cultivated due to their high medicinal and economic value. Taking Astragalus as an example, to ensure better growth, the planting spacing needs to be controlled during cultivation. This facilitates the absorption of nutrients from the soil and promotes better photosynthesis. Common Astragalus seed collection and sowing devices often experience seed clogging during the feeding process because the seeds tend to cluster together. Excessive seed aggregation can also lead to empty seed collection slots, resulting in excessively large planting spacing and negatively impacting the economic benefits of cultivation. Utility Model Content

[0003] The purpose of this application is to provide a quantitative seed collection and sowing device to solve the problems mentioned in the background art. When sowing Astragalus seeds, the Astragalus seeds tend to accumulate together and become blocked during the feeding process. Furthermore, the excessive accumulation of Astragalus seeds can cause the seed collection trough in the seed collection mechanism to become empty, resulting in excessively large planting spacing and affecting the economic benefits of Astragalus cultivation.

[0004] To achieve the above objectives, this application provides the following technical solution: a quantitative seed-taking and sowing device, comprising a support frame, a movable component installed at the bottom of the support frame for traction of the support frame, a seed-holding bin, an auxiliary cylinder, and a single-shaft motor fixedly mounted on the support frame, the auxiliary cylinder being located directly below the seed-holding bin, and a conveying pipe fixedly connected between the seed-holding bin and the auxiliary cylinder, a discharge pipe fixedly connected to the bottom of the auxiliary cylinder, a driven shaft inserted into the seed-holding bin, and the connection between the seed-holding bin and the driven shaft being rotatably connected via a bearing, the auxiliary... A drive shaft is inserted into the cylinder, and the auxiliary cylinder is rotatably connected to the drive shaft via a bearing. A first sprocket is fixedly sleeved on the outside of the driven shaft, and a second sprocket and a seed-collecting roller are fixedly sleeved on the outside of the drive shaft. A transmission chain is installed on the first sprocket and the second sprocket. Several agitator blades are installed on the driven shaft, and all of the agitator blades are located inside the seed chamber. Two symmetrically arranged seed-collecting grooves are opened on the circumferential side of the seed-collecting roller. An extension component is installed on the outside of the auxiliary cylinder, and the extension component is used to further convey the seeds discharged from the discharge pipe.

[0005] Furthermore, the top of the seed storage bin is hinged with a cover plate, and a latch is installed on the cover plate for fixing the seed storage bin and the cover plate.

[0006] Furthermore, the seed storage bin, auxiliary cylinder, conveying pipe, and discharge pipe are all located on the same vertical axis.

[0007] Furthermore, the extension assembly includes an extension tube and a guide rod. The extension tube is slidably sleeved on the outside of the discharge tube. The top end of the guide rod is fixedly mounted on the auxiliary cylinder. A slider is fixed to the outer wall of the extension tube. The slider is slidably sleeved on the guide rod. A bolt is threaded onto the slider. The bolt is used to fix the guide rod and the slider.

[0008] Furthermore, the guide rod is provided with a plurality of slots, which are arranged linearly in the longitudinal direction.

[0009] Furthermore, a stop block is fixed at the bottom end of the guide rod.

[0010] Furthermore, the moving component includes a base plate, the support frame is fixedly mounted on the base plate, a dual-axis motor and two universal wheels are fixedly mounted on the bottom of the base plate, the two output shafts of the dual-axis motor are connected to a transmission rod through a coupling, rollers are fixedly sleeved on the outside of the transmission rod, and a push rod is fixed on the upper surface of the base plate.

[0011] In summary, the technical effects and advantages of this utility model are as follows: In this invention, when the drive shaft is rotated by a single-axis motor, the drive shaft pulls the second sprocket to rotate, which in turn pulls the first sprocket to rotate via a transmission chain. The first sprocket then drives the driven shaft to rotate, causing several agitators on the driven shaft to continuously agitate the Astragalus seeds temporarily stored in the seed hopper. This prevents the Astragalus seeds from clogging the feed inlet of the conveying pipe. As the Astragalus seeds are agitated, they smoothly and orderly enter the conveying pipe one by one. At the same time, the drive shaft pulls the seed-collecting roller to rotate, which, together with the auxiliary cylinder, uses the seed-collecting groove to orderly extract the Astragalus seeds discharged from the discharge outlet of the conveying pipe. In this way, the phenomenon of empty seed collection can be effectively avoided, the efficiency of seed collection and sowing can be reasonably controlled, and the spacing of Astragalus planting can be better controlled.

[0012] In this invention, by pulling down the extension tube, the final distance of the Astragalus seeds from the ground can be adjusted to adapt to the operational needs of planting Astragalus under different soil conditions of looseness. The downward movement of the extension tube can pull the slider down accordingly. By using a wrench to turn the bolt into the corresponding slot, the guide rod and the slider can be locked, thereby locking the relative position of the discharge tube and the extension tube and ensuring the stability of the extension tube's position when discharging the Astragalus seeds.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example: Reference Figure 1-6The illustrated quantitative seed collection and sowing device includes a support frame 1. A movable component is installed at the bottom of the support frame 1 for traction and movement. A seed holding chamber 2, an auxiliary cylinder 3, and a single-shaft motor 4 are fixedly installed on the support frame 1. The auxiliary cylinder 3 is located directly below the seed holding chamber 2, and a conveying pipe 5 is fixedly connected between the seed holding chamber 2 and the auxiliary cylinder 3. A cover plate 15 is hinged to the top of the seed holding chamber 2, and a latch is installed on the cover plate 15 for fixing the seed holding chamber 2 and the cover plate 15. The latch on the cover plate 15 can fix the seed holding chamber 2 to the cover plate 15, so that the cover plate 15 seals the top of the seed holding chamber 2 and prevents the Astragalus seeds inside the seed holding chamber 2 from falling out due to the shaking of the device. A discharge pipe 6 is fixedly connected to the bottom of the auxiliary cylinder 3. The device consists of the seed holding chamber 2, the auxiliary cylinder 3, the conveying pipe 5, and the discharge pipe 6. All are located on the same vertical axis, which is more conducive to the smooth transport of seeds. A driven shaft 7 is inserted into the seed holding chamber 2, and the connection between the seed holding chamber 2 and the driven shaft 7 is rotatably connected by a bearing. An active shaft 8 is inserted into the auxiliary cylinder 3, and the connection between the auxiliary cylinder 3 and the active shaft 8 is rotatably connected by a bearing. A first sprocket 9 is fixedly sleeved on the outside of the driven shaft 7, and a second sprocket 10 and a seed taking roller 13 are fixedly sleeved on the outside of the active shaft 8. A transmission chain 11 is installed on the first sprocket 9 and the second sprocket 10. Multiple stirring blades 12 are installed on the driven shaft 7, and the multiple stirring blades 12 are all located inside the seed holding chamber 2. Two symmetrically arranged seed taking grooves 14 are opened on the circumferential side of the seed taking roller 13. An extension component is installed on the outside of the auxiliary cylinder 3. The extension component is used to further transport the seeds discharged from the discharge pipe 6. When the single-axis motor 4 drives the drive shaft 8 to rotate, the drive shaft 8 pulls the second sprocket 10 to rotate, which in turn pulls the first sprocket 9 to rotate via the transmission chain 11. The first sprocket 9 drives the driven shaft 7 to rotate, so that the multiple agitators 12 on the driven shaft 7 can continuously agitate the Astragalus seeds temporarily stored in the seed storage bin 2, preventing the Astragalus seeds from clogging the feed inlet of the conveying pipe 5. Astragalus seeds enter the conveying pipe 5 smoothly and orderly during the agitation process. At the same time, the drive shaft 8 pulls the seed-taking roller 13 to rotate, so that the seed-taking roller 13, together with the auxiliary cylinder 3, uses the seed-taking groove 14 to extract the Astragalus seeds discharged from the discharge outlet of the conveying pipe 5 in an orderly manner. In this way, the phenomenon of empty extraction can be effectively avoided.

[0018] The extension assembly includes an extension tube 16 and a guide rod 17. The extension tube 16 is slidably sleeved on the outside of the discharge tube 6. The top end of the guide rod 17 is fixedly installed on the auxiliary cylinder 3. A slider 18 is fixed on the outer wall of the extension tube 16. The slider 18 is slidably sleeved on the guide rod 17. A bolt 19 is threaded onto the slider 18. The bolt 19 is used to fix the guide rod 17 and the slider 18. The guide rod 17 has multiple slots 21. The multiple slots 21 are arranged linearly in the longitudinal direction. The bolt 19 can be screwed into the slots 21 to make the fixation between the guide rod 17 and the slider 18 more secure. A stop block 20 is fixed at the bottom end of the guide rod 17. The stop block 20 can prevent the slider 18 from completely detaching from the guide rod 17, thereby preventing the extension tube 16 from completely separating from the discharge tube 6. By pulling down the extension tube 16, the final distance of the Astragalus seeds from the ground can be adjusted to adapt to the operational needs of planting Astragalus under different soil conditions of looseness. The downward movement of the extension tube 16 can pull the slider 18 down accordingly. By using a wrench to turn the bolt 19 into the corresponding slot 21, the guide rod 17 and the slider 18 can be locked, thereby locking the relative position of the discharge tube 6 and the extension tube 16, ensuring the stability of the extension tube 16 when discharging the Astragalus seeds.

[0019] The movable component includes a base plate 22, a support frame 1 is fixedly installed on the base plate 22, a dual-axis motor 23 and two universal wheels 26 are fixedly installed at the bottom of the base plate 22, the two output shafts of the dual-axis motor 23 are connected to a transmission rod 24 through a coupling, a roller 25 is fixedly sleeved on the outside of the transmission rod 24, and a push rod 27 is fixed on the upper surface of the base plate 22. The two rollers 25 are driven to rotate by the dual-axis motor 23, so that the two rollers 25, together with the two casters 26, pull the device forward. Holding the push rod 27 can move the device better.

[0020] Working principle of this utility model: Unlock the latch, rotate the cover plate 15, and place the treated Astragalus seeds into the seed storage chamber 2 from the top. After the seeds are placed, close the cover plate 15 and secure the seed storage chamber 2 to the cover plate 15 again with the latch. Power the single-axis motor 4 using the outdoor portable power supply on the device. When the single-axis motor 4 is running, it drives the drive shaft 8 to rotate. The drive shaft 8 pulls the second sprocket 10 to rotate. The second sprocket 10 pulls the first sprocket 9 to rotate via the transmission chain 11. The first sprocket 9 pulls the driven shaft 7 to rotate, causing the multiple agitator plates 1 on the driven shaft 7 to rotate. 2. The Astragalus seeds at the bottom of the inner side of the seed storage bin 2 are continuously agitated. The agitated Astragalus seeds will not block the feed inlet of the conveying pipe 5, and can enter the interior of the conveying pipe 5 smoothly and orderly. When the drive shaft 8 rotates, it will pull the seed picking roller 13 to rotate. The Astragalus seeds in the conveying pipe 5 will move down under their own gravity. The rotating seed picking roller 13 can use its own seed picking groove 14 to complete the seed picking operation one by one in an orderly manner and send the seeds to the discharge pipe 6, so that the Astragalus seeds are guided into the extension pipe 16 along the discharge pipe 6, and finally fall into the soil along the extension pipe 16. Before the single-axis motor 4 starts running, the user can hold the push rod 27 to activate the dual-axis motor 23 to drive the two rollers 25 to rotate. The two rollers 25, together with the two casters 26, can move in the field. Due to the different soil softness, the distance between the extension tube 16 and the ground in this device will change. It is necessary to pull the extension tube 16 down according to the site conditions to adjust the distance between the extension tube 16 and the ground. Use a wrench to turn the bolt 19 into the slot 21. In this way, the adjusted extension tube 16 is locked. The single-axis motor 4 runs at the same time as the dual-axis motor 23, so that the device can move in the field and carry out the sowing of Astragalus in an orderly manner. Finally, the user covers some soil on the Astragalus seeds to complete the sowing work.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
