Description

Technical Field

[0001] This application belongs to the field of agricultural implements, specifically a rotary tillage and deep fertilization wheat seeding machine. Background Technology

[0002] Seeders use mechanical structures to achieve quantitative and targeted seeding, replacing traditional manual sowing or spot sowing methods. They have advantages such as improving sowing efficiency, reducing labor intensity, and ensuring sowing quality.

[0003] Currently, in crop cultivation, wheat is a tillering crop, and a single plant can produce multiple tillers (lateral branches), forming a group competition. Uniform sowing can avoid local over-density which would inhibit tillering, or over-sparse sowing which would waste land. Corn, on the other hand, needs to improve the light penetration of the middle and lower leaves and reduce canopy closure, so it is necessary to set up wide rows for it during the sowing process. In order to make full use of land resources, narrow rows are set up for it during the planting process, ultimately forming a planting method with wide and narrow row spacing.

[0004] Since corn and wheat require different intervals during planting, using the same seeder to complete the operation may lead to reduced efficiency, lower seeding quality, and waste of resources. Therefore, a rotary tillage deep fertilization wheat uniform seeder is proposed to solve the above problems. Utility Model Content

[0031] like Figure 1 , Figure 2 and Figure 9 As shown, a rotary tillage deep fertilization wheat uniform seeder includes a planting vehicle 1. A seed storage box 2 is provided at the rear of the planting vehicle 1. The seed storage box 2 is used to hold the seeds to be sown. The inside of the seed storage box 2 is provided with a cavity. The top and bottom of the cavity of the seed storage box 2 are connected to the external environment. The bottom opening width of the seed storage box 2 is narrower than the top opening width.

[0032] As a preferred method, such as Figure 8 and Figure 9 As shown, the seed storage box 2 is equipped with a material blocking assembly 13, which includes a slide 131. The slide 131 is formed on the bottom inner wall of the seed storage box 2. A stop block 132 is slidably connected to the inner wall of the slide 131. The number of stop blocks 132 is set to multiple, and the multiple stop blocks 132 are arranged in a linear array along the left and right direction. The width of the stop block 132 is narrower than the width of the seed. The side of the stop block 132 away from the bottom opening of the seed storage box 2 is elastically connected to the inner wall of the slide 131 by a spring 133. One end of the spring 133 is fixed to the side of the stop block 132 away from the bottom opening of the seed storage box 2. The other end of the spring 133 is fixedly connected to the inner wall of the slide 131. The length of the slide 131 is longer than half the width of the bottom opening of the seed storage box 2. The length of the stop block 132 is longer than half the width of the bottom opening of the seed storage box 2. By setting the length of the stop block 132, it is ensured that the stop block 132 can completely cover the bottom opening of the seed storage box 2 to prevent seeds from falling. The bottom end of the stop block 132 is provided with an inclined chamfer on the side near the middle of the seed storage box 2. By setting the inclined chamfer, it is ensured that when the chamfer is subjected to force, the stop block 132 can move in the direction of the slide 131.

[0033] As a preferred method, such as Figure 3 , Figure 5 , Figure 6 and Figure 10As shown, a rotating rod 3 is located directly below the seed storage box 2. The outer wall of the rotating rod 3 has multiple control grooves 4. A sowing wheel 5 is mounted on the outside of the rotating rod 3. The control grooves 4 are aligned at one end of a straight line, approximately 20 cm apart. At the other end of the same straight line, the control grooves 4 are grouped in pairs. The distance between two control grooves 4 in the same group is the same as the width of the sowing wheel 5. However, the distances between adjacent groups of control grooves 4 are alternately set at 40 cm and 90 cm. A control groove is fixedly connected to the inner circumferential wall of the sowing wheel 5. The ball 10 and the control ball 10 are set inside the control groove 4. The diameter of the control ball 10 matches the width of the control groove 4. The outer wall of the sowing wheel 5 is provided with a seed storage groove 6. With the setting of the seed storage groove 6, after the sowing wheel 5 rotates to the position of the seed storage groove 6 directly above it, the seeds inside the seed storage box 2 can enter the seed storage groove 6 under the action of gravity. The outer wall of the sowing wheel 5 is provided with an annular slide 7. Each sowing wheel 5 has two annular slides 7 on its outer wall. The two annular slides 7 are respectively set on the inner wall of the sowing wheel 5 on the left and right sides of the seed storage groove 6. The cross-sectional shape of the annular slide 7 is T-shaped.

[0034] As a preferred method, such as Figure 2 , Figure 3 and Figure 7 As shown, a feeding block 8 is slidably connected to the inner wall of the annular slide 7. The top of the feeding block 8 is provided with an arc-shaped protrusion in the annular slide 7, and the shape of the arc-shaped protrusion matches the shape of the annular slide 7. The bottom of the feeding block 8 is set in an inclined shape. The number of seeding wheels 5 is even. A feeding block 8 is provided on the outside of each seeding wheel 5. A feeding groove is opened at the top of the feeding block 8. The shape of the feeding groove is a quarter cylinder. Counting from left to right, the feeding blocks 8 in odd positions and the feeding groove of the feeding block 8 on their right can be combined to form a semi-cylindrical groove.

[0035] As a preferred method, such as Figure 3 and Figure 7As shown, a shielding component 14 is provided inside the feeding block 8. The shielding component 14 includes a mounting groove 141, which is formed on the inner wall of the feeding block 8. A control block 142 is slidably connected to the inner wall of the feeding block 8. The control block 142 is T-shaped, and a seed-blocking plate 143 is fixedly connected to the top of the control block 142. The seed-blocking plate 143 is used to block the falling wheat seeds, ensuring that the wheat seeds can move along the direction of the feeding groove formed on the inner wall of the feeding block 8. The bottom end of the control block 142 is elastically connected to the inner wall of the mounting groove 141 by a spring 144. One end of the second spring 144 is fixedly connected to the bottom end of the control block 142, and the other end of the second spring 144 is fixedly connected to the inner wall of the mounting groove 141. The inner wall of the control block 142 is provided with a control groove 145, which is a right triangle. The inner wall of the feeding block 8 is slidably connected with a pressure block 146. The side of the pressure block 146 near the control block 142 is provided with a sharp corner that matches the shape of the control groove 145. The outer wall of the pressure block 146 is fixedly connected with a baffle 147. The baffle 147 is set to ensure that it cannot fall out of the inside of the feeding block 8.

[0036] As a preferred method, such as Figures 3-5 As shown, a locking assembly 9 is provided on the outer side of the rotating rod 3. The locking assembly 9 includes a fixed wheel 91. The inner wall of the fixed wheel 91 is fixedly connected to the outer right wall of the rotating rod 3. The fixed wheel 91 is annular and is concentrically arranged with the rotating rod 3. The inner wall of the fixed wheel 91 has two threaded grooves 92. The angle between the line connecting the two threaded grooves 92 and the midpoint of the fixed wheel 91 and the angle between the line connecting the two ends of the control groove 4 and the midpoint of the seeding wheel 5 are the same angle projected onto the left surface of the fixed wheel 91. A limit rod 93 is threadedly connected to the inner wall of the threaded groove 92. The right end of the limit rod 93 is provided with a groove that is connected to the threaded groove 92. 2. A threaded area with a matching shape. The outer wall of the limiting rod 93 penetrates the inner wall of the sowing wheel 5. The inner wall of the sowing wheel 5 has a hole with a diameter that matches the limiting rod 93. The left outer wall of the rotating rod 3 is rotatably connected to the rotating wheel 94. The left end of the rotating wheel 94 has a hole with a diameter that matches the diameter of the limiting rod 93. When the limiting rod 93 rotates out of the threaded groove 92, the length of the right part of the limiting rod 93 entering the left end hole of the rotating wheel 94 increases. When the limiting rod 93 rotates into the threaded groove 92, the length of the right part of the limiting rod 93 entering the left end hole of the rotating wheel 94 decreases. The length of the rotating wheel 94 is longer than the length of the spiral area on the right side of the limiting rod 93.

[0037] As a preferred method, such as Figures 3-5As shown, sliding plates 11 are rotatably connected to the left and right sides of the rotating rod 3. A sliding rod 12 is provided below the rotating rod 3. There is a preset distance between the sliding rod 12 and the rotating rod 3. The left and right ends of the sliding rod 12 are fixedly connected to the sliding plates 11. The outer wall of the rotating wheel 94 is rotatably connected to the outer wall of the sliding plate 11. The outer wall of the sliding rod 12 passes through and is slidably connected to the inner wall of the unloading block 8. By setting the sliding rod 12, it is ensured that the unloading block 8 can only move left and right relative to the sliding rod 12.

[0038] As a preferred method, such as Figures 3-5 As shown, a drive mechanism 15 is provided on the left side of the rotating rod 3. The drive mechanism 15 includes a motor 151. The driver's cab of the planting vehicle 1 is equipped with a controller for controlling the motor 151. The output shaft of the motor 151 is fixedly connected to a rotating sleeve 152. The rotating sleeve 152 is cylindrical in shape. An insert block 153 is slidably connected to the inner wall of the rotating sleeve 152. The insert block 153 is frustoconical in shape, and a groove is provided on the outer wall of the insert block 153. A limiting plate is provided at the end of the insert block 153 near the motor 151 to prevent it from leaving the rotating sleeve 152. The end of the insert block 153 near the motor 151 is connected to the inner wall of the rotating sleeve 152 by a spring 151. 4. Elastic connection: one end of spring 3 154 is fixedly connected to the end of insert block 153 near motor 151, and the other end of spring 3 154 is fixedly connected to the inner wall of rotating sleeve 152. A slot 155 is provided in the middle of the right end of rotating rod 3. A connecting frame 16 is provided at the rear of planting vehicle 1. The inner wall of connecting frame 16 is fixedly connected to the outer wall of seed storage box 2. The inner surface of connecting frame 16 is slidably connected to slide plate 11. A fixing piece for fixing slide plate 11 is provided on connecting frame 16. The inner wall of connecting frame 16 is through and rotatably connected to the outer wall of rotating sleeve 152. A placement plate is fixedly connected to the right end of connecting frame 16. Motor 151 is fixedly connected to the upper surface of placement plate.

[0039] Working principle: When switching planting varieties, the operator first releases the fixation of the slide plate 11, and then moves the slide plate 11 downward. When the slide plate 11 moves to the lower end, there is a distance between the seeding wheel 5 and the bottom of the seed storage box 2, so the seeding wheel 5 does not contact the stop block 132 at this time.

[0040] At this time, the staff first rotates the limiting rod 93 separately while manually fixing the rotating rod 3. When the limiting rod 93 rotates until its left end leaves the threaded groove 92, the rotating wheel 94 is rotated. Since the left end of the limiting rod 93 is in the hole inside the rotating wheel 94, the rotating wheel 94 drives the limiting rod 93 to rotate around its axis during the rotation. During the rotation of the limiting rod 93, it pushes the inner wall of the sowing wheel 5, thus driving the sowing wheel 5 to rotate synchronously with it.

[0041] Since the rotating rod 3 is manually fixed, the seeding wheel 5 can rotate relative to the rotating rod 3 during rotation. Since the control ball 10 is inside the control groove 4, the outer wall of the control ball 10 moves along the corresponding direction of the inner wall of the control groove 4 during rotation, so the position of the seeding wheel 5 in the left and right directions can be adjusted.

[0042] After the position of the seeding wheel 5 is adjusted, the worker rotates the limiting rod 93 again, so that the spiral area at the right end of the limiting rod 93 enters the interior of the new thread groove 92. Since the fixed wheel 91 is fixed to the rotating rod 3, the fixed wheel 91 is fixed relative to the limiting rod 93 at this time, so the rotating rod 3 is fixed relative to the limiting rod 93.

[0043] At this point, the staff moves the skateboard 11 upward and secures it with fasteners.

[0044] During the upward movement of the slide plate 11, when the slide plate 11 contacts the outer wall of the insert block 153, since the insert block 153 is frustum-shaped, its bottom end can move in the direction of entering the rotating sleeve 152 after being subjected to force.

[0045] After the slide plate 11 has moved, since the insert block 153 is at the same height as the slot 155, the insert block 153 moves towards entering the slot 155 under the action of the spring force of the spring 154.

[0046] Since the shape of the slot 155 matches the shape of the insert 153, two situations arise: one is that the recessed position of the insert 153 matches the protrusion of the slot 155, and the other is that the recessed position of the insert 153 does not match the protrusion of the slot 155.

[0047] If the recessed position of the insert 153 happens to match the protrusion of the slot 155, then when the motor 151 is started, the output shaft of the motor 151 can drive the rotating sleeve 152 and the insert 153 to rotate, and directly push the protrusion of the slot 155 through the recessed surface of the insert 153, thereby driving the rotating rod 3 to rotate.

[0048] However, if they do not fit perfectly, the motor 151 will first drive the rotating sleeve 152 and the insert 153 to rotate. When the recessed position of the insert 153 fits perfectly with the protruding position of the slot 155, the insert 153 will first enter the interior of the slot 155 under the elastic force of the spring 154, and then drive the rotating rod 3 to rotate. Therefore, at this position, after the motor 151 starts, it can indirectly drive the rotating rod 3 to rotate.

[0049] At the same time, as the rotating rod 3 moves upward with the slide plate 11, it drives the seeding wheel 5 to move synchronously with it. After the seeding wheel 5 moves to the upper position, its top pushes the inclined surface at the bottom of the stop block 132, so that the stop block 132 moves in the direction of entering the slide groove 131. Therefore, at this time, the upper part of the seeding wheel 5 is located inside the seed storage box 2.

[0050] At this time, when the motor 151 starts, the motor 151 indirectly drives the rotating rod 3 to rotate, thereby making the seeding wheel 5 rotate synchronously with it.

[0051] When the seed storage trough 6 is rotated to the top position, the seeds enter the seed storage trough 6 under the action of gravity. As the rotating rod 3 continues to rotate, the seeds rotate accordingly. When the rotation reaches the bottom, the seeds enter the feeding trough of the feeding block 8 again under the action of gravity and move downward along the feeding trough until they fall to the ground.

[0052] If wheat is being planted at this time, the seeding wheels 5 are in a state of separation and the distance between each pair of seeding wheels 5 is the same. Therefore, the pressing block 146 is not squeezed at this time. Thus, the control block 142 moves upward under the elastic force of the spring 144, thereby driving the seed baffle plate 143 to move upward, which can ensure that the wheat seeds move in the direction of the feeding trough of the feeding block 8.

[0053] If the plant is corn, the seeding wheels 5 are in pairs, so the pressing block 146 is under pressure and moves towards the control groove 145 after being pressed. Therefore, the inclined surface of the pressing block 146 pushes the inclined surface of the control groove 145. Thus, the control block 142 moves downward after being pressed on the inclined surface, and drives the seed baffle plate 143 to move downward, so that the seed baffle plate 143 between the two adjacent feeding blocks 8 enters the interior of the installation groove 141.

[0054] Therefore, the corn seeds can first move to the middle position between the two feeding blocks 8 under the action of the arc surface of the feeding trough at the top of the feeding block 8, and then move down along the slope of the feeding trough, thus ensuring that the planting position is appropriate.
