Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, in particular to a fixed-point sowing device for agricultural planting. Background Art

[0002] Fixed-point seeding involves sowing seeds at specific locations in the soil, according to a predetermined row and plant spacing and at a predetermined seeding depth. This method ensures even seed distribution throughout the field or garden, while providing each seed with ample space to grow. Fixed-point seeding is primarily suitable for crops with high seed spacing requirements, such as large-seed crops like corn, cotton, sugar beets, sunflowers, ginkgo biloba, walnuts, and horse chestnuts. It is also suitable for rare tree species and horticultural crops that require precise seed distribution.

[0003] When sowing, farmers simply place the seeds into the fixed-point sowing tube, which ensures they fall directly into the planting pit. Once the seeds hit the soil, they need to be covered with soil to provide protection and a suitable germination environment. The sowing device is typically equipped with a covering device to apply soil to the seeds. This covering device is designed to ensure that the soil covers the seeds evenly and tightly, while avoiding excessive pressure on the seeds.

[0004] In the existing technical solution, when the seeds are conveyed to the opening of the furrow opener, they will fall directly or be dropped into the soil through vibration; however, when sowing in this way, there will be a problem of seeds scattering when they are directly dropped or discharged from the opening of the furrow opener by vibration. Some seeds will fall to different positions in the furrow, which will affect the effect of fixed-point sowing and may cause uneven density of crops during growth. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the seeds in the fixed-point sowing sleeve provided by the present invention fall into the furrow, they are blocked by the fixed-point sowing sleeve on the outside, thereby reducing the problem of overly dispersed distribution when the seeds are sown. The fixed-point sowing sleeve can ensure that the seeds are subject to certain constraints and guidance when falling into the furrow, thereby reducing the phenomenon of seeds scattering. This allows the seeds to be sown more accurately according to the predetermined position and spacing, improving the accuracy and consistency of sowing. The precise sowing position and uniform seed distribution help the crops form a reasonable population structure during the growth process, which is conducive to the crops to fully utilize resources such as light, water and nutrients, thereby improving the yield and quality of the crops.

[0019] 2. The crushing pressure plate on the outside of the bottom end of the fixed-point sowing sleeve of the present invention knocks, squeezes and crushes the large nodular soil blocks around the seeds. The presence of nodular soil blocks will affect the air permeability and water retention of the soil, which is not conducive to the germination of seeds and the growth of crops. Through the extrusion and crushing process, these soil blocks can be broken, making the soil looser and finer, thereby improving the physical and chemical properties of the soil. The crushed soil particles are finer and have a larger contact area with the seeds, which is beneficial for the seeds to absorb water and nutrients in the soil. At the same time, the loose soil environment is also beneficial to the expansion of the seed root system, thereby improving the germination rate and survival rate of the seeds.

[0020] 3. The present invention can stir and mix the seeds and fertilizers that fall into the sowing material tube by moving the dial plate up and down. The stirring and mixing process can evenly combine the seeds and fertilizers, so that the two steps of fertilizing and sowing can be completed at one time during sowing, thereby improving the efficiency of sowing; through stirring and mixing, the fertilizer can be evenly distributed around the seeds, providing sufficient nutrients for the seeds, which helps the seeds better absorb and utilize nutrients during germination and growth, and promotes the healthy growth of crops.

[0021] 4. The present invention can further stir and mix the seeds and fertilizers in the seeding material tube through the rotation of the paddle; the circulation of air in the seeding material tube can play a certain driving role on the sown seeds, so that the seeds can be sprayed at the designated position under the action of the airflow, thereby achieving the effect of fixed-point sowing.

[0034] The present invention provides a technical solution:

Wheel frames 2 are fixedly installed on both sides of the bottom end of the sowing carrying box 1, and a carrying wheel 13 is rotatably installed at the bottom end of the wheel frame 2. A sowing material pipe 6 is fixedly installed at the front end of the bottom of the sowing carrying box 1. The sowing material pipe The bottom end of 6 is fixedly connected to the plowshare 5, and the sowing material tube 6 and the inner and outer parts of the carrier 3 are jointly provided with a driving sowing assembly 4, which includes an insertion hole 412 opened inside the plowshare 5, and a fixed-point sowing sleeve 410 is slidably installed inside the insertion hole 412. The upper end of the fixed-point sowing sleeve 410 is rotatably penetrated by a plug shaft 409, and a driven rod 408 is fixedly installed in the middle position of the plug shaft 409. The top of the driven rod 408 is fixedly connected to the driving rod 404, and the structure of the driving rod 404 is L The driven wheel frame 401 is fixedly mounted on the front of the bottom end of the carrier 3, and the bottom end of the driven wheel frame 401 is rotatably connected to the driven wheel 402, and the middle position of the driven wheel 402 is fixedly mounted with a regulating ridge 403; the bottom end of the driving rod 404 is a semi-spherical structure, and the vertical end of the driving rod 404 slides through the interior of the driven wheel frame 401, and the bottom end of the vertical end of the driving rod 404 abuts against the end surface of the regulating ridge 403, and the interior of the driven wheel frame 401 is provided with an assembly groove 407, and the assembly groove 407 is fixed to the middle position of the driven wheel 402. A fixed connecting seat 405 and a spring 406 are provided inside 07. The fixed connecting seat 405 is slidably connected to the inner bottom end of the assembly groove 407. The upper end surface of the fixed connecting seat 405 is fixedly connected to the bottom end of the spring 406. The inner side wall of the fixed connecting seat 405 is fixedly connected to the outer wall of the driving rod 404; crushing pressure plates 411 are fixedly installed on both sides of the outer wall and the bottom of the front end of the fixed-point sowing sleeve 410. There are three crushing pressure plates 411 located at equal angles on the left, right and rear of the outer wall of the bottom end of the fixed-point sowing sleeve 410.

[0036] By adopting the above technical solution, when in use, the sowing carrier box 1 is installed on a traction device such as a tractor, so that the sowing carrier box 1 can be driven to move, and the sowing carrier box 1 can move with the traction device through the carrying wheel 13 on the wheel frame 2. When the sowing carrier box 1 moves, it can plow the place where it is to be sown through the plow head 5, so that the seeds to be sown can be sown in the plow furrows. When the sowing carrier box 1 moves, the driven wheel 402 on the driven wheel frame 401 contacts the ground, so that the driven wheel 402 on the driven wheel frame 401 can be moved. When the driven wheel 402 rotates, the rotation of the driven wheel 402 can drive the regulating edge block 403 to rotate, and the regulating edge block 403 and the driving rod 404 abut against each other, so that when the regulating edge block 403 rotates, the driving rod 404 can be pushed to move, and the driving rod 404 can move up and down inside the driven wheel frame 401. When the driving rod 404 moves up and down, it can drive the fixed connecting seat 405 to move. When the fixed connecting seat 405 moves upward, the fixed connecting seat 405 can further compress the spring 406 inside the assembly groove 407, so that the spring The spring 406 can store energy. When the driving rod 404 moves upward, the driving rod 404 can drive the driven rod 408 to move upward. The driven rod 408 can drive the fixed-point sowing sleeve 410 to move upward through the plug-in shaft 409 by moving upward, so that the fixed-point sowing sleeve 410 can be partially retracted into the insertion hole 412. When the regulating edge block 403 no longer applies force to the driving rod 404, the driving rod 404 can drive the driving rod 404 and the driven rod 408 to move downward under the joint action of the spring 406 and the fixed connection seat 405. In this way, the driven rod 408 can drive the fixed-point sowing sleeve 410 to move downward through the plug-in shaft 409, so that when the seeds in the fixed-point sowing sleeve 410 fall into the furrow, they are blocked by the fixed-point sowing sleeve 410 on the outside, thereby reducing the problem of too scattered distribution when the seeds are sown. The fixed-point sowing sleeve 410 can ensure that the seeds are subject to certain constraints and guidance when falling into the furrow, thereby reducing the scattering of seeds. This allows the seeds to be sown more accurately according to the predetermined position and spacing, thereby improving the accuracy and consistency of sowing.The accurate seeding position and uniform seed distribution help the crops form a reasonable population structure during the growth process, which is beneficial to the crops to fully utilize the resources such as light, water and nutrients, thereby improving the yield and quality of the crops; when the fixed-point seeding sleeve 410 moves downward, the broken pressing plate 411 outside the bottom end of the fixed-point seeding sleeve 410 performs a knocking and extruding broken treatment on the large nodular soil clumps existing around the seeds, the existence of the nodular soil clumps will affect the air permeability and water retention of the soil, which is not conducive to the germination of the seeds and the growth of the crops, through the extruding broken treatment, the soil clumps can be broken, so that the soil becomes more loose and fine, thereby improving the physical and chemical properties of the soil, the soil particles after the broken treatment are finer and smaller, the contact area with the seeds is larger, which is beneficial to the seeds to absorb the water and nutrients in the soil, at the same time, the loose soil environment is also beneficial to the root system of the seeds to expand, thereby improving the germination rate and survival rate of the seeds.

[0037] Specifically, as shown in Figures 4 to 6 and Figure 8 , the inside of the fertilizer bin 10 is provided with a stirring feeding assembly 8, the stirring feeding assembly 8 includes a guide rod 801 fixedly installed at the top end of the driven rod 408, the rear end bottom of the guide rod 801 is fixedly installed with a toothed plate 802, the inside of the fertilizer bin 10 is rotatably installed with a driving shaft 808, the outer wall of the driving shaft 808 is fixedly installed with a stirring feeding plate 804, the corresponding outer wall of the driving shaft 808 is fixedly installed with a gear 803, the bottom end of the toothed plate 802 is fixedly installed with a plunger 805, the bottom end surface of the seeding bearing box 1 is provided with a feeding plug hole 806 corresponding to the plunger 805, the bottom end surface of the seeding bearing box 1 is fixedly installed with a feeding guide seat 807 corresponding to the feeding plug hole 806, the feeding guide seat 807 and the seeding material pipe 6 are in communication with each other; the inside of the seeding material pipe 6 is provided with a poking assembly 9, the poking assembly 9 includes a poking plate 901 rotatably installed on the inner wall of the seeding material pipe 6, the poking plate 901 and the inner wall of the seeding material pipe 6 are rotatably installed with a connecting shaft 902, one end of the poking plate 901 close to the driven rod 408 is fixedly installed with a connecting rope 906 inside, the poking plate 901 and the driven rod 408 are soft-connected through the connecting rope 906, the middle position of the poking plate 901 is provided with a poking groove 903, the inside of the poking groove 903 is rotatably installed with a poking shaft 904, the outer wall of the poking shaft 904 is fixedly installed with a poking piece 905.

[0038] By adopting the above technical solution, when in use, when the driven rod 408 moves up and down, the driven rod 408 can drive the guide rod 801 to move up and down, and the guide rod 801 moves up and down, which can drive the tooth plate 802 to move up and down. When the tooth plate 802 moves up and down, it can drive the gear 803 to rotate by engaging with the teeth of the gear 803. When the gear 803 rotates, the gear 803 can drive the driving shaft 808 to rotate. The rotation of the driving shaft 808 can drive the stirring feed plate 804 to rotate. The stirring of the stirring feed plate 804 can effectively destroy the fertilizer lumps and restore it to a loose state, which is convenient for fertilization and crop absorption. Different types of fertilizers can be mixed evenly to ensure that each fertilizer particle contains the same nutrient ratio, which helps crops obtain a balanced nutrient supply during growth and avoids growth differences caused by uneven fertilizer distribution; when the tooth plate 802 moves up and down, it will also synchronously drive the plunger 805 to move up and down. When the plunger 805 moves up and down, the opening and closing of the feed plug hole 806 can be controlled. When the feed plug hole 806 is opened, the fertilizer can be dialed into the feed plug hole 806 by rotating the stirring feed plate 804, so that the fertilizer can be introduced into the feed guide seat 807 through the feed plug hole 806. The setting of the inclined channel in the feed guide seat 807 can make the seeds and fertilizers evenly distributed. The seeding tube 6 is introduced into the seeding material tube 6. It should be noted that half of the feed plug hole 806 is communicated with the fertilizer bin 10, and the other half of the feed plug hole 806 is communicated with the seed bin 11. In this way, when the feed plug hole 806 is opened, both seeds and fertilizers can be introduced into the seeding material tube 6; when the driven rod 408 moves up and down, the driven rod 408 can be rotated up and down at a certain angle through the connecting rope 906 and the dial plate 901, and the dial plate 901 can be rotated within a certain range of angles through the connecting shaft 902 under the action of external force. It should be noted that when the driven rod 408 moves to the top, the two symmetrical dial plates 901 are pulled relative to each other by the connecting rope 906. They are closed to each other. When the driven rod 408 moves downward, the paddle 901 opens and closes downward under the action of its own gravity and the gravity of the seeds and fertilizers, so that the seeds and fertilizers can be discharged from the sowing material tube 6. The seeds and fertilizers that fall into the sowing material tube 6 can be stirred and mixed by the up and down movement of the paddle 901. The stirring and mixing process can evenly combine the seeds and fertilizers, so that the two steps of fertilizing and sowing can be completed at one time during sowing, thereby improving the efficiency of sowing; through stirring and mixing, the fertilizer can be evenly distributed around the seeds, providing sufficient nutrients for the seeds, which helps the seeds to better absorb and utilize nutrients during germination and growth, and promotes the healthy growth of crops.

[0039] Specifically, such as Figure 3 、 Figure 5 and Figure 8As shown, a pneumatic drive assembly 7 is provided at the upper end of the seeding material pipe 6, and the pneumatic drive assembly 7 includes an elastic air bag 701 fixedly mounted on the upper end of the seeding material pipe 6, and a pressure plate 704 located above the elastic air bag 701 is fixedly mounted on the upper outer wall of the driven rod 408, and the left and right ends of the elastic air bag 701 are fixedly connected to a one-way air intake valve pipe 703, and the middle position of the bottom end of the elastic air bag 701 is fixedly connected to a pneumatic drive conduit 702, and the pneumatic drive conduit 702 extends to the interior of the seeding material pipe 6.

[0040] By adopting the above technical solution, when in use, when the driven rod 408 moves up and down, the driven rod 408 moves downward to drive the pressure plate 704 to move downward synchronously, so that the elastic airbag 701 below can be squeezed through the pressure plate 704, so that the gas inside the elastic airbag 701 can be introduced into the seeding material tube 6 through the air pressure drive conduit 702, thereby driving the air flow inside the seeding material tube 6. When the elastic airbag 701 is not under pressure, the elastic airbag 701 can expand and reset under the action of its own elasticity, so that the outside air can be sucked into the elastic airbag 701 through the one-way air inlet valve tube 703, and the air circulation in the seeding material tube 6 can drive the paddle 905 to rotate. It should be noted here that the air flow in the seeding material tube 6 has an effect on the paddle 9 The driving force generated by 05 is greater than the resistance encountered when the paddle 905 rotates. The rotation of the paddle 905 can drive the dial shaft 904 to rotate, so that multiple paddles 905 can rotate in the dial groove 903. The rotation of the paddle 905 can further stir and mix the seeds and fertilizers in the sowing material tube 6. At the same time, the rotation of the paddle 905 can make the seeds and fertilizers in the sowing material tube 6 fall from the dial groove 903 for sowing. The circulation of air in the sowing material tube 6 can play a certain driving role on the sowing seeds, so that the seeds can be sprayed at a designated position under the action of the airflow, thereby achieving the effect of fixed-point sowing. It should be noted that under the action of the resistance of the paddle 905 and the paddle 901, the circulating air can only spray the seeds out and will not cause the seeds to be randomly distributed.

[0041] Working principle: When in use, the sowing carrier box 1 is installed on a traction device such as a tractor, so as to drive the sowing carrier box 1 to move. The sowing carrier box 1 can move with the traction device through the carrying wheel 13 on the wheel frame 2. When the sowing carrier box 1 moves, it can plow the place where it is to be sown through the plow head 5, so that the seeds to be sown can be sown in the plow furrow. When the sowing carrier box 1 moves, the provided carrying frame 3 can carry and support the driving sowing component 4, and the driven wheel 402 on the driven wheel frame 401 contacts the ground. Thus, the driven wheel 402 can rotate on the driven wheel frame 401, and the rotation of the driven wheel 402 can drive the regulating edge block 403 to rotate. The regulating edge block 403 and the driving rod 404 abut each other, so that when the regulating edge block 403 rotates, the driving rod 404 can be pushed to move, and the driving rod 404 can move up and down inside the driven wheel frame 401. When the driving rod 404 moves up and down, it can drive the fixed connecting seat 405 to move. When the fixed connecting seat 405 moves upward, the fixed connecting seat 405 can contact the assembly groove 404. 07 is further compressed, so that the spring 406 can store energy. When the driving rod 404 moves upward, the driving rod 404 can drive the driven rod 408 to move upward. The driven rod 408 can drive the fixed-point sowing sleeve 410 to move upward through the plug-in shaft 409 by moving upward, so that the fixed-point sowing sleeve 410 can be partially retracted into the insertion hole 412. When the regulating edge block 403 no longer applies force to the driving rod 404, the driving rod 404, under the joint action of the spring 406 and the fixed connection seat 405, The driving rod 404 and the driven rod 408 can be driven to move downward, so that the driven rod 408 can drive the fixed-point sowing sleeve 410 to move downward through the plug-in shaft 409. In this way, when the seeds in the fixed-point sowing sleeve 410 fall into the furrow, the fixed-point sowing sleeve 410 is blocked on the outside, thereby reducing the problem of too scattered distribution when the seeds are sown. When the fixed-point sowing sleeve 410 moves downward, the crushing pressure plate 411 on the outside of the bottom end of the fixed-point sowing sleeve 410 knocks, squeezes and crushes the large nodules around the seeds.When the driven rod 408 moves up and down, the driven rod 408 can drive the guide rod 801 to move up and down, the guide rod 801 moves up and down, and the tooth plate 802 can be driven to move up and down, the tooth plate 802 moves up and down, and the gear 803 can be driven to rotate through the mutual engagement between the teeth of the gear 803, when the gear 803 rotates, the gear 803 can drive the driving shaft 808 to rotate, the driving shaft 808 rotates and drives the stirring material plate 804 to rotate, when the tooth plate 802 moves up and down, the plunger 805 can be synchronously driven to move up and down, the plunger 805 moves up and down, and the opening and closing control of the material insertion hole 806 can be realized, when the material insertion hole 806 is opened, the fertilizer can be pushed into the material insertion hole 806 through the rotation of the stirring material plate 804, so that the fertilizer can be introduced into the material guide seat 807 through the material insertion hole 806, and through the setting of the inclined channel in the material guide seat 807, the seeds and the fertilizer can be introduced into the seeding material pipe 6, one half of the material insertion hole 806 and the fertilizer bin 10 are in communication with each other, and the other half of the material insertion hole 806 and the seed bin 11 are in communication with each other, so that when the material insertion hole 806 is opened, the seeds and the fertilizer can be introduced into the seeding material pipe 6, the partition plate 12 can separate the fertilizer bin 10 and the seed bin 11, and the partition plate 12 and the rear tooth plate 802 are in sliding contact.

[0042] When the driven rod 408 moves up and down, the driven rod 408 can be rotated and swung up and down at a certain angle through the connecting rope 906 and the dial plate 901. The dial plate 901 can be rotated at a certain angle within a certain range through the connecting shaft 902 under the action of external force. It should be noted here that when the driven rod 408 moves to the top, the two symmetrical dial plates 901 are pulled together by the connecting rope 906. When the driven rod 408 moves downward, the dial plates 901 open and close downward under the action of their own gravity and the gravity of the seeds and fertilizers. When the driven rod 408 moves up and down, the driven rod 408 moves downward to drive the pressure plate 704 to move downward synchronously, so that the elastic air bag 701 below can be squeezed by the pressure plate 704, so that the gas inside the elastic air bag 701 can be introduced into the sowing material pipe 6 through the air pressure drive conduit 702, so as to drive the air flow inside the sowing material pipe 6. When the elastic air bag 701 is not under pressure, the elastic air bag 701 can expand and reset under its own elastic action. In this way, the outside air can be sucked into the elastic airbag 701 through the one-way air inlet valve tube 703, and the air can be circulated in the seeding material tube 6 to drive the paddle 905 to rotate. It should be noted here that the driving force generated by the air flow in the seeding material tube 6 on the paddle 905 is greater than the resistance encountered when the paddle 905 rotates. The rotation of the paddle 905 can drive the dial shaft 904 to rotate, so that multiple paddles 905 can rotate in the dial groove 903. The rotation of the paddle 905 can further stir the seeds and fertilizers in the seeding material tube 6. Mixing processing, at the same time, through the rotation of the paddle 905, the seeds and fertilizers in the sowing material tube 6 can fall from the paddle groove 903 for sowing, and the circulation of air in the sowing material tube 6 can play a certain driving role on the sown seeds, so that the seeds can be sprayed at a designated position under the action of the air flow, thereby achieving the effect of fixed-point sowing. When the sowing is completed, the device can be equipped with a soil coverer, and the soil is covered on the seeds that have fallen into the ditch through the soil coverer. The soil coverer can be a chain link type, a drag plate type, etc. This is a prior art and will not be repeated here.
