Description

Technical Field

[0001] The invention relates to the technical field of vegetable planting, and in particular to a point-seeding machine for vegetable planting. Background Art

[0002] Vegetable planting involves many links, usually including seed selection, seedling raising, cultivation, field management and harvesting. Existing seedling raising methods for vegetable planting include direct sowing, seedling raising in plug trays and seedbed seedling raising. Plug tray seedling raising provides an independent growth space for each seed through the holes in the plug tray, which is convenient for management and transplantation. A spot-seeding machine is usually used for plug tray seedling raising. The spot-seeding machine has good sowing accuracy and can place seeds in the soil according to a predetermined spacing and depth. However, when the spot-seeding machine puts soil into the plug tray, the existing spot-seeding machine puts soil onto the plug tray through a discharging roller and scrapes the soil through a scraper. However, since the amount of soil put by the discharging roller is fixed, and the soil that was originally squeezed and compacted becomes loose due to falling, more and more soil is accumulated at the scraper, which will cause the scraper to squeeze more and more soil into the holes, resulting in differences in the amount of soil in different holes in the same plug tray, and then there is a situation where the soil and nutrients required for seed growth in different holes are insufficient, which affects the growth of the seeds. Summary of the invention

[0015] 2. The present invention changes the angle of the rotating plate by measuring the weight of the soil released. When the soil is squeezed excessively and the amount of soil released by the feeding rack is too much, the rotating plate tends to be more horizontal, slowing down the falling speed of the soil and avoiding too much soil on the hole tray, which causes the soil to be too compacted after subsequent squeezing and affects the growth of seeds.

The CNC table of the second CNC base 2 on the left is electrically connected, and the start and stop of the electric rotating shaft 6 is controlled by the induction device on the feeding rack 5. A feeding roller 7 is fixedly connected to the middle of the electric rotating shaft 6, and two groups of bulldozers with central symmetrical distribution are fixedly connected to the feeding roller 7.

[0023] like Figure 2 and Figure 3 As shown, the cross-section of the limit block 8 is elliptical, and is used to cooperate with the adjacent extrusion columns on the T-shaped block 9 and the n-shaped frame 1401 to change the distance between the T-shaped block 9, the n-shaped frame 1401 and the feed roller 7. The T-shaped block 9 is used to block the upper side of the bulldozer plate in the feed roller 7 to prevent the bulldozer plate in the feed roller 7 from bringing out excess soil when discharging, and to prevent the shielding plate 1402 fixed between the two n-shaped frames 1401 from hindering the rotation of the bulldozer plate in the feed roller 7.

[0024] like Figure 2-Figure 4As shown, the vibration component includes two flower-shaped wheels 1501 symmetrically distributed front and back, the two flower-shaped wheels 1501 are respectively fixed to the front and rear sides of the electric rotating shaft 6, the flower-shaped wheels 1501 are provided with a number of arc-shaped protrusions uniformly distributed in the circumferential direction, and the right side of the feeding rack 5 is slidably connected with two guide plates 1502 symmetrically distributed front and back, the cross-sections of the two guide plates 1502 are both Z-shaped, and the upper parts of the outer sides of the two symmetrically distributed guide plates 1502 are fixedly connected with limiting columns, and the two symmetrically distributed limiting columns are respectively pressed and matched with adjacent flower-shaped wheels 1501 to drive the two symmetrically distributed guide plates 1502 to move left and right, and the lower parts of the two symmetrically distributed guide plates 1502 are respectively slidably connected with the two symmetrically distributed L-shaped plates 3, and an oblique plate 1503 is slidably connected up and down between the two symmetrically distributed guide plates 1502, and the distance from the left side of the oblique plate 1503 to the left side of the inside of the feeding rack 5 is less than when the shielding plate 1402 slides to the leftmost side. The distance from the left side surface to the left side surface inside the feeding rack 5, the outer side surfaces of the two symmetrically distributed L-shaped plates 3 are fixedly connected to the limit plate 1504, and a third spring 1505 is fixedly connected between the right side surface of the guide plate 1502 and the left side surface of the adjacent limit plate 1504. The right sides of the two symmetrically distributed guide plates 1502 are jointly fixedly connected with a V-shaped plate 1506, and a certain distance is set between the left side of the upper part of the V-shaped plate 1506 and the right side surfaces of the two symmetrically distributed guide plates 1502. The two symmetrically distributed L-shaped plates 3 are jointly fixedly connected with two cleaning machines 15 (the cleaning machine 15 is an existing device, and the internal structure is no longer repeated). The cleaning machine 15 on the left is located between the V-shaped plate 1506 and the pit pressing machine 16, and the cleaning machine 15 on the right is located on the right side of the soil covering machine 18, and the two cleaning machines 15 are respectively electrically connected to the adjacent second CNC base 2, and an adjustment component for adjusting the feeding speed according to the soil weight is arranged between the two symmetrically distributed guide plates 1502.

[0025] like Figure 2-Figure 4As shown, the adjustment component includes a support plate 1601, the support plate 1601 is fixed between two symmetrically distributed guide plates 1502, the upper side of the support plate 1601 is fixed with two symmetrically distributed first elastic telescopic rods 1602, the upper sides of the telescopic ends of the two symmetrically distributed first elastic telescopic rods 1602 are fixed with the oblique plate 1503, the lower sides of the two symmetrically distributed guide plates 1502 are fixed with second elastic telescopic rods 1603, the fixed part of the first elastic telescopic rod 1602 is connected to the fixed part of the adjacent second elastic telescopic rod 1603 through a pipeline, and the fixed part of the first elastic telescopic rod 1602, the fixed part of the second elastic telescopic rod 1603 and the pipeline are connected. Both are filled with hydraulic oil, a rack 1604 is fixed to the right side of the telescopic end of the second elastic telescopic rod 1603, the inner diameter of the fixed part of the second elastic telescopic rod 1603 is smaller than the inner diameter of the fixed part of the first elastic telescopic rod 1602, which is used to increase the moving distance of the rack 1604, and the lower parts of the two symmetrically distributed guide plates 1502 are rotatably connected to gears 1605, and the gears 1605 are meshed with adjacent racks 1604. The two symmetrically distributed gears 1605 are commonly fixed to a rotating plate 1606, and the two symmetrically distributed guide plates 1502 are rotatably connected to the rotating plate 1606. The rotating plate 1606 is used to buffer excess soil to prevent excessive soil on the hole tray.

[0026] When using the device for vegetable planting and sowing, the staff first powers on the device through the CNC tables on the first CNC base 1 and the two second CNC bases 2, puts the vegetable seeds to be sown into the grooves on the seeder 17, and adds soil to the feeding rack 5 and the covering machine 18. Then, the staff places the plug tray on the conveyor belt 4 on the left side of the device. The two sides of the plug tray are limited by the horizontal plate of the L-shaped plate 3, and driven by the conveyor belt 4 on the left side, it starts to move to the right. When the plug tray moves a certain distance After the feed rack 5 is separated, the sensing device of the feeding rack 5 senses the hole tray and starts the electric shaft 6. The electric shaft 6 rotates to drive the feeding roller 7 and the two limit blocks 8 to rotate clockwise. The feeding roller 7 rotates to push the soil in the feeding rack 5 through the bulldozer on the feeding roller 7, and puts the soil onto the inclined plate 1503. Due to the different heights of the bulldozers on the feeding roller 7, the amount of soil carried by a group of bulldozers decreases in sequence during the half-turn of the feeding roller 7. When the feeding roller 7 rotates half a turn, the amount of soil required for one hole tray is completed. When the soil is put in, the two limit blocks 8 rotate and squeeze the two squeezing columns on the T-shaped block 9, so that the T-shaped block 9 slides upward and compresses the first springs 10 evenly distributed in a straight line to avoid blocking the highest bulldozer on the feed roller 7. As the two limit blocks 8 rotate, the T-shaped block 9 slides up and down to adapt to the height of the bulldozer, thereby maintaining the distance between the bulldozer and the T-shaped block 9, blocking the soil and ensuring that the bulldozer does not carry out excessive soil. At the same time, the two limit blocks 8 rotate and gradually squeeze the squeezing columns on the two N-shaped frames 1401, so that the two N-shaped frames 1401 slide to the left. The sliding of the two N-shaped frames 1401 to the left drives the baffle plate 1402 to compress the second springs 1404 evenly distributed in a straight line to slide to the left, so as to increase the distance between the baffle plate 1402 and the bulldozer on the feed roller 7, ensuring that the long bulldozer on the feed roller 7 can pass. As the limit blocks 8 rotate, the baffle plate 1402 continuously slides left and right while the T-shaped block 9 continuously slides up and down, thereby making adaptive changes.

[0027] While the bulldozer on the feed roller 7 pushes the soil onto the inclined plate 1503, the electric shaft 6 drives the two flower-shaped wheels 1501 to rotate. The two flower-shaped wheels 1501 rotate and continuously squeeze the limit pins on the two guide plates 1502. Driven by the third spring 1505, the two guide plates 1502 move left and right. The left and right movement of the two guide plates 1502 drives the inclined plate 1503 and the rotating plate 1606 to move left and right, so that the inclined plate 1503 and the rotating plate 1606 produce a vibration effect, which accelerates the soil from the inclined plate 1503 to the rotating plate 160 6 and then slides onto the hole tray at a speed that causes the soil to fall onto the hole tray along the inclined plate 1503 and the rotating plate 1606, and then the conveyor belt 4 continues to drive the hole tray to move to the right and contact with the V-shaped plate 1506. The V-shaped plate 1506 scrapes the excess soil on the surface of the hole tray to the left to fill the missing soil on the left, and the two guide plates 1502 move left and right to drive the V-shaped plate 1506 to move left and right, so that the V-shaped plate 1506 simulates the action of a person using a rake to level the soil, thereby enhancing the effect of the V-shaped plate 1506 in scraping the soil and improving the flatness of the soil falling on the hole tray.

[0028] When the soil dropped onto the inclined plate 1503 is too heavy, the inclined plate 1503 slides downward along the two guide plates 1502, and the downward sliding of the inclined plate 1503 drives the telescopic parts of the two first elastic telescopic rods 1602 to move downward, compressing the spring therein, and pressing the liquid in the fixed part of the first elastic telescopic rod 1602 into the fixed part of the adjacent second elastic telescopic rod 1603, so that the telescopic ends of the two second elastic telescopic rods 1603 move rightward, and the telescopic ends of the two second elastic telescopic rods 1603 move rightward and respectively drive the adjacent racks 1604 to move rightward, and the rightward movement of the two racks 1604 drives the two gears 1605 to rotate counterclockwise, and the counterclockwise rotation of the two gears 1605 drives the rotating plate 1606 to rotate counterclockwise together, thereby changing the discharge speed of the soil on the rotating plate 1606. The degree of soil sliding onto the hole tray is prevented, when the weight of the soil dropped onto the oblique plate 1503 is reduced, the compressed springs in the two first elastic telescopic rods 1602 drive the telescopic ends thereof to move upward, the telescopic ends of the two first elastic telescopic rods 1602 move upward to drive the oblique plate 1503 to move upward and reset, and the liquid in the fixed part of the adjacent second elastic telescopic rod 1603 is drawn back to the fixed part of the first elastic telescopic rod 1602, so that the telescopic parts of the two second elastic telescopic rods 1603 move leftward, the telescopic parts of the two second elastic telescopic rods 1603 move leftward and respectively drive the adjacent racks 1604 to move leftward, the two racks 1604 move leftward and drive the two gears 1605 to rotate clockwise, the two gears 1605 rotate clockwise and drive the rotating plate 1606 to rotate clockwise and reset.

[0029] After the filling is completed, the hole tray contacts the middle conveyor belt 4, and continues to move to the right with the conveyor belt 4. The soil on the upper surface of the hole tray is leveled and the excess soil is swept away by the cleaner 15 on the left. When the hole tray moves to the lower side of the pit pressing machine 16, the sensing device of the pit pressing machine 16 senses the position of the hole tray, and the pit pressing machine 16 starts to run, pressing the soil in the holes on the hole tray out of the holes. When the conveyor belt 4 continues to drive the hole tray to move to the right and passes the seeder 17, the sensing device of the seeder 17 senses the position of the hole tray and starts to put seeds into the holes in the holes on the hole tray. Finally, it passes through the covering machine 18. The covering machine 18 senses the position of the hole tray and starts to put soil on the hole tray to fill the holes in the holes on the hole tray, and uses the cleaner 15 on the right to clean the excess soil to complete the sowing process of one hole tray. The above actions are repeated until the sowing of all hole trays is completed.

[0030] After the required seeding holes are completed, the staff cuts off the power supply of the device through the first CNC base 1 and the two second CNC bases 2.

A torsion spring is fixedly connected between the material receiving frame 1707 and the second fixed frame 1705, which is used to prevent the material receiving frame 1707 from colliding with the ventilation plate 1702 when the rotating rod 1701 rotates. The cross-section of the material receiving frame 1707 is J-shaped, which is used to prevent the seeds from sliding along the inclined surface of the material receiving frame 1707 after the seeds are received. A limiting rod 1708 is fixedly connected to the lower part of the inner side surface of the ventilation plate 1702, and the right side surface of the material receiving frame 1707 is limited by the limiting rod 1708.

[0032] When the ventilation plate 1702 uses negative pressure to absorb seeds through an external air pump, the gas in the ventilation plate 1702 is reduced because the needle is blocked by the seeds, and the suction force gradually increases. The outside air enters the fixed part of the adjacent third elastic telescopic rod 1704 through the adjacent first one-way valve 1709. At this time, the ventilation plate 1702 absorbs the gas in the two third elastic telescopic rods 1704, causing the telescopic parts of the two third elastic telescopic rods 1704 to move downward. The second fixing frame 1705 is driven to move downward, and the second fixing frame 1705 drives a plurality of straight and evenly distributed receiving frames 1707 to move downward. The plurality of straight and evenly distributed receiving frames 1707 move downward and squeeze the limiting rod 1708 to rotate clockwise. At the same time, the torsion spring is twisted and stored, so that the receiving frame 1707 is below the needle. When the seeds adsorbed by the needle fall, the pressure in the ventilation plate 1702 is reduced due to the gas entering from the needle, and the two third elastic telescopic rods 1704 The telescopic part begins to move upward and reset under the action of the spring force, but the flow area of ​​the second one-way valve 1710 is small, which delays the reset speed of the telescopic parts of the two third elastic telescopic rods 1704, ensuring that the needle head picks up the fallen seeds, and then the rotating rod 1701 drives the ventilation plate 1702 and its attached parts to swing clockwise, and the receiving rack 1707 puts the seeds into the feeding pipe by inertia. After completing one seed delivery, the ventilation plate 1702 is refilled with gas, and the gas enters the fixed parts of the two third elastic telescopic rods 1704 through the pipeline, so that the telescopic ends of the two third elastic telescopic rods 1704 move upward quickly, and the telescopic ends of the two third elastic telescopic rods 1704 drive the second fixed frame 1705 to move upward, and a number of straight and evenly distributed receiving racks 1707 move upward to gradually release the squeezing with the limit rod 1708, and reset under the drive of the torsion spring, and when the telescopic part of the third elastic telescopic rod 1704 moves upward a certain distance, the reset of the two third elastic telescopic rods 1704 is completed.
