Figures 1 to 13 As shown, a hole-piercing and seeding device for leafy vegetables in a plant factory comprises a hole-piercing and seeding mechanism 1 and a first vertical reciprocating mechanism 3. The hole-piercing and seeding mechanism 1 is located above a conveyor belt. The hole-piercing and seeding mechanism 1 comprises a conveying pipe 1-1 and a hole-piercing needle 1-3 connected to the conveying pipe 1-1. The hole-piercing needle 1-3 is used to pierce into a cross opening of a planting sponge on the conveyor belt and seed. The first vertical reciprocating mechanism 3 is connected to the hole-piercing needle 1-3. The reciprocating mechanism is used to make the hole-piercing needle 1-3 reciprocate in the vertical direction, so that the hole-piercing needle 1-3 is pulled out after completing the hole-piercing and seeding of the cross opening of a planting sponge, and then the hole-piercing and seeding is performed on the cross opening of the next planting sponge conveyed by the conveyor belt.

[0043] When the conveyor belt transports the planting sponge to the bottom of the acupuncture needle 1-3, the first vertical reciprocating mechanism 3 drives the acupuncture needle 1-3 downward, and the acupuncture needle 1-3 enters the cross opening of the planting sponge. The seeds of leafy vegetables enter the acupuncture needle 1-3 through the conveying tube 1-1, and then enter the cross opening of the planting sponge. After the planting is completed, the first vertical reciprocating mechanism 3 drives the acupuncture needle 1-3 to move upward and move out the planting sponge. The next planting sponge reaches the bottom of the acupuncture needle 1-3 under the conveyance of the conveyor belt, and the first vertical reciprocating mechanism 3 drives the acupuncture needle 1-3 downward again to perform acupuncture and planting at the cross opening of the planting sponge. This cycle is repeated in sequence, and all leafy vegetable seeds are planted. The device simplifies the planting process of leafy vegetable seeds and improves work efficiency.

[0044] Reference Figures 1 to 3 ,as well as Figure 8 and Fig. 9 As shown, it also includes: a box body 4-1, which is connected to the side wall of the platform above the transmission belt, a first vertical reciprocating mechanism 3 includes a rectangular limit frame, an eccentric wheel located in the limit frame, a slide plate abutting the eccentric wheel and sliding in the length direction of the limit frame, and a return spring connected between the slide plate and the limit frame, the slide plate is fixedly connected to the acupuncture needle 1-3, the eccentric wheel is rotatably connected to the box body 4-1, the limit frame is fixedly connected to the box body 4-1, and the length direction of the limit frame is the vertical direction, so that when the eccentric wheel rotates, the slide plate reciprocates in the vertical direction to drive the acupuncture needle 1-3 to reciprocate in the vertical direction.

[0045] Reference Figures 1 to 3 ,as well as Figure 8 and Fig. 9 As shown, the limit frame in the first vertical reciprocating mechanism 3 is recorded as the second limit frame 3-2, the eccentric wheel is the second eccentric wheel 3-3, the slide plate is recorded as the second slide plate 3-1, and the return spring is recorded as the second return spring 3-4. A fixed block 1-2 is connected to the acupuncture needle 1-3, the second slide plate 3-1 is connected to the acupuncture needle 1-3 through the fixed block 1-2, and the second limit frame 3-2 is connected to the box body 4-1 through the connecting block 2-3. When it is necessary to acupuncture and plant the planting sponge, the second eccentric wheel 3-3 is controlled to rotate. The rotation of the second eccentric wheel 3-3 drives the second slide plate 3-1 to move up and down in the vertical direction along the second limit frame 3-2. The movement of the second slide plate 3-1 in the vertical direction drives the fixed block 1-2 connected to the second slide plate 3-1 to move up and down. The fixed block 1-2 moves up and down, drives the acupuncture needle 1-3 connected to the fixed block 1-2 to move up and down, and the vertical movement of the acupuncture needle 1-3 can be achieved by rotating the second eccentric wheel 3-3. The invention simplifies the planting process of leafy vegetable crop seeds and improves the work efficiency.

[0046] Reference Figures 1 to 3 ,as well as Figure 5 and Figure 6 As shown, it also includes a horizontal reciprocating mechanism 2, which has the same structure as the first vertical reciprocating mechanism 3. The limit frame of the horizontal reciprocating mechanism 2 is located at the bottom of the first vertical reciprocating mechanism 3. The length direction of the limit frame of the horizontal reciprocating mechanism 2 is the horizontal direction, so that when the eccentric wheel rotates, the slide plate reciprocates in the horizontal direction to drive the acupuncture needles 1-3 to reciprocate in the horizontal direction.

[0047] Reference Figures 1 to 3 ,as well as Figure 5 and Figure 6As shown, the limit frame in the horizontal reciprocating mechanism 2 is recorded as the first limit frame 2-1, the eccentric wheel is the first eccentric wheel 2-2, the slide plate is recorded as the first slide plate 2-4, and the return spring is recorded as the first return spring 2-5, which controls the first eccentric wheel 2-2 to rotate. The rotation of the first eccentric wheel 2-2 drives the first slide plate 2-4 to move left and right along the horizontal direction of the first limit frame 2-1. The horizontal movement of the first slide plate 2-4 drives the fixed block 1-2 connected to the first slide plate 2-4 to move left and right. The left and right movement of the fixed block 1-2 drives the piercing needle 1-3 connected to the fixed block 1-2 to move in the horizontal direction. When the piercing needle 1-3 moves to the lowest point, the planting sponge is pierced with holes. At the same time, the seeds of leafy crops are controlled to be discharged through the seed discharge port of the seed metering device and enter the conveying pipe 1-1. Under the action of gravity, they fall into the piercing needle 1-3. The seeds enter the holes along the piercing needle 1-3. In the process of the piercing needle 1-3 moving to the lowest point, the seeds are moved to the seed discharge port of the seed metering device. The second return spring 3-4 connected to the second slide plate 3-1 gradually changes from a compressed state to a normal non-compressed state, and the first eccentric wheel 2-2 and the second eccentric wheel 3-3 rotate synchronously. There is a 90° phase difference between the first eccentric wheel 2-2 and the second eccentric wheel 3-3, so that when the second slide plate 3-1 moves downward, the first slide plate 2-4 moves horizontally to the right, so that the acupuncture needle 1-3 connected thereto corresponds to the hole position of the planting sponge, so that the planting sponge on the conveyor belt can be pierced and planted. Then, as the second eccentric wheel 3-3 and the first eccentric wheel 2-2 continue to rotate, the second slide plate 3-1 moves upward, and the first slide plate 2-4 moves horizontally to the left under the action of the first return spring 2-5 connected to the first slide plate 2-4, thereby driving the acupuncture needle 1-3 to reset upward and rightward, and the conveyor belt moves the next planting sponge to the bottom of the acupuncture needle 1-3 to carry out the next planting operation, and the planting is carried out while the acupuncture is being carried out. Fig. 9 , Fig. 9 The acupuncture needle movement trajectory A of the acupuncture needle 1-3 under the action of the first vertical reciprocating mechanism and the horizontal reciprocating mechanism and the acupuncture position B of the implantation sponge. The setting of the horizontal reciprocating mechanism 2 avoids affecting the acupuncture needle 1-3 when the conveyor belt moves, thereby improving work efficiency.

[0048] Reference Figures 1 to 3 ,as well as Figures 14 to 18 As shown, it also includes an anti-movement mechanism 5, which includes: a clamping plate 5-5, a connecting rod 5-3 and a second vertical reciprocating mechanism. The clamping plate 5-5 is located on one side of the acupuncture needle 1-3, the connecting rod 5-3 is vertically connected to the clamping plate 5-5, and the second vertical reciprocating mechanism is connected to the connecting rod 5-3. The second vertical reciprocating mechanism is used to give a downward force to the implant sponge when the acupuncture needle 1-3 rises.

[0049] The structure of the second vertical reciprocating mechanism can be the same as that of the first vertical reciprocating mechanism 3, or it can be different from that of the first vertical reciprocating mechanism 3, and can realize the up and down reciprocation of the pressing plate 5-5, so that when the acupuncture needle 1-3 is pulled out, the implant sponge will not be driven to move upward.

[0050] Refer again Figures 1 to 3 ,as well as Figures 14 to 18 As shown, the second vertical reciprocating mechanism includes: a rotating disk 5-1, a fixed rod 5-6 and a connecting plate 5-2. The rotating disk 5-1 is rotatably connected to the box body 4-1, the fixed rod 5-6 is fixedly connected to the rotating disk 5-1, the fixed rod 5-6 is close to the edge of the rotating disk 5-1, the connecting rod 5-3 is connected to the connecting plate 5-2, and a semicircular groove is opened on the connecting plate 5-2. The diameter of the semicircular groove is close to the connecting rod 5-3, and the fixed rod 5-6 is slidably connected to the semicircular groove.

[0051] During the process of piercing and sowing, the rotating disk 5-1 is controlled to rotate, and the fixed rod 5-6 fixedly connected to the rotating disk 5-1 rotates, and the fixed rod 5-6 is slidably connected to the semicircular groove. When the fixed rod 5-6 slides in the semicircular groove of the connecting plate 5-2, it drives the connecting rod 5-3 and the pressing plate 5-5 to move up and down. When the pressing plate 5-5 presses the planting sponge, the piercing needle 1-3 moves at the same time to pierce the sponge to form a hole for sowing, ensuring that the planting sponge does not move with the reciprocating motion of the piercing needle 1-3, thereby affecting the sowing position and subsequent sowing quality. After the piercing needle 1-3 moves upward, the pressing plate 5-5 moves upward to separate from the planting sponge, and the planting sponge is placed on the conveyor belt and moves under the drive of the conveyor belt to carry out the sowing operation at the next position. The second vertical reciprocating mechanism makes the pressing and moving up and down simple, and improves work efficiency.

[0052] Reference Figures 1 to 3 ,as well as Figures 10 to 13 As shown, the device also includes a transmission mechanism 4, which includes a first gear 4-6, a second gear 4-7 and a third gear 4-8, which are all rotatably connected to the box body 4-1. A motor is connected to the first gear 4-6, and the first gear 4-6, the second gear 4-7 and the third gear 4-8 are meshed in sequence. The first gear 4-6 is fixedly connected to the rotating disk 5-1, the rotation center of the second gear 4-7 is connected to the eccentric wheel of the first vertical reciprocating mechanism 3, and the rotation center of the third gear 4-8 is connected to the eccentric wheel of the first vertical reciprocating mechanism 3, so that when the first gear 4-6 rotates, the flip disk and the eccentric wheel are also rotated.

[0053] The first gear 4-6 is fixedly connected to a rotating shaft 4-3, one end of which extends out of the box body 4-1 and is fixedly connected to the rotating disk 5-1. The rotating shaft 4-3 is rotatably connected to the box body 4-1 through a tapered roller bearing 4-2. The other end of the rotating shaft 4-3 extends out of the box body 4-1 and is connected to a motor fixed on the side of the platform. The second gear 4-7 is fixedly connected to a first output shaft 4-4, one end of which extends out of the box body 4-1 and is connected to the second eccentric wheel 3-3. -4 is rotatably connected to the housing 4-1 through a tapered roller bearing 4-2, the third gear 4-8 is fixedly connected to the second output shaft 4-5, one end of the second output shaft 4-5 extends out of the housing 4-1 and is connected to the first eccentric wheel 2-2, the second output shaft 4-5 is rotatably connected to the housing 4-1 through a tapered roller bearing 4-2, the first limit frame 2-1 is connected to the housing 4-1 through a connecting block 2-3, and the second limit frame 3-2 is also connected to the housing 4-1 through a connecting block 2-3. The setting of the transmission mechanism 4 allows the rotation of the rotating disk 5-1, the first eccentric wheel 2-2 and the second eccentric wheel 3-3 to only require one power input, making the device simpler, and controlling one motor can realize the acupuncture needle 1-3 acupuncture and the anti-movement of the pressing plate 5-5, further improving the work efficiency.

[0054] Refer again Figures 1 to 3 ,as well as Figures 14 to 18 As shown, the anti-movement mechanism 5 also includes a limit block 5-4, one end of which is sleeved on the connecting rod 5-3, and the other end of which is connected to the box body 4-1. The limit block 5-4 is used to limit the movement direction of the connecting rod 5-3. By setting the limit block 5-4, the connecting rod 5-3 has only the degree of freedom in the up and down directions, thereby preventing the connecting rod 5-3 from swinging left and right.

[0055] Reference Fig.15 As shown, Fig.15 This is an axial side view of the anti-movement mechanism in the embodiment of the present invention. The shape of the clamping plate 5-5 is U-shaped, and the outer edge of the clamping plate 5-5 is arc-shaped.

[0056] The outer edge of the clamping plate 5-5 is arc-shaped and U-shaped. The outer side of the clamping plate 5-5 has rounded edges and is arc-shaped, so that the clamping plate 5-5 can prevent the sharp corners from damaging the sponge when compressing the sponge block. The U-shaped shape of the clamping plate 5-5 makes the compression more stable during acupuncture, reduces disturbance to the implanted sponge, and does not interfere with the operation of the acupuncture needle 1-3, further improving work efficiency.

[0057] Refer again Figures 1 to 4 As shown, the acupuncture seeding mechanism 1 also includes an air inlet pipe 1-4, which is connected to the side wall of the acupuncture needle 1-3 so that positive pressure airflow enters the acupuncture needle 1-3 from the air inlet pipe 1-4 to blow out the seeds in the acupuncture needle 1-3.

[0058] If there is no air inlet pipe 1-4, the seeds will be blocked in the acupuncture needle 1-3. The diameter of the acupuncture needle 1-3 is larger to ensure that the seeds can enter the acupuncture holes smoothly. The coordinated use of the air inlet pipe 1-4 and the acupuncture needle 1-3 makes it easier for the seeds to enter the acupuncture holes, and the seeds can enter the acupuncture needle 1-3 before the holes are pierced. When the acupuncture needle 1-3 is acupuncturing, it is only necessary to allow positive pressure airflow to enter the acupuncture needle 1-3 from the air inlet pipe 1-4 to blow out the seeds in the acupuncture needle 1-3, thereby further improving the working efficiency.

[0059] The slide plate is an H-shaped slide plate, the eccentric wheel is lower than the H-shaped cross beam, and the two ends of the H-shaped slide plate are respectively sleeved on the two sides of the limit frame, so that the movement of the acupuncture needles 1-3 is more stable.

[0060] The diameter of the hole at the bottom of the puncture needle 1-3 is 4 mm. The diameter of 4 mm is sufficient for most leafy vegetable crop seeds to pass through smoothly, and is not too large to cause the puncture needle 1-3 to fall before entering the planting sponge.

[0061] The radius of the groove provided on the connecting plate 5-2 is 40 mm. This makes the total displacement of the clamping plate up and down 40 mm, which improves the working efficiency without affecting the hole-piercing and seeding.

[0062] The material of the conveying tube 1-1 is soft plastic. The soft plastic material can reduce the damage to the seeds.

[0063] The material of the connecting rod 5-3 and the acupuncture needle 1-3 is stainless steel, and the surface is chrome-plated to increase the hardness. The acupuncture needle increases the hardness to make it easier to pierce the implant sponge, and the acupuncture needle and the connecting rod 5-3 are easy to wear, and the surface is smooth and not easy to wear.

[0064] The first gear 4-6, the second gear 4-7 and the third gear 4-8 are all made of 40Cr and are carburized to increase strength.

[0065] Working principle: The present invention is a device for piercing and seeding leafy vegetables in a plant factory. The leafy vegetable seeds are discharged through the seeding port of the seeding device, enter the conveying pipe 1-1, and fall into the piercing needle 1-3 under the action of gravity. The motor is controlled to rotate, so that the rotating shaft 4-3 rotates, and the first output shaft 4-4 and the second output shaft 4-5 are transmitted through the first gear 4-6, the second gear 4-7 and the third gear 4-8. The first output shaft 4-4 drives the second eccentric wheel 3-3 to rotate, and the second output shaft 4-5 drives the first eccentric wheel 2-2 to rotate. The second eccentric wheel 3-3 rotates to drive the second slide plate 3- 1 moves up and down, the first eccentric wheel 2-2 rotates to drive the first slide plate 2-4 to move left and right, thereby driving the acupuncture needle 1-3 connected to the first slide plate 2-4 and the second slide plate 3-1 to reciprocate, and the rotating shaft 4-3 simultaneously drives the rotating disk 5-1 of the anti-movement mechanism 5 to rotate synchronously, and the fixing rod 5-6 fixedly connected to the rotating disk 5-1 slides in the groove of the connecting plate 5-2, driving the connecting rod 5-3 and the pressing plate 5-5 to move up and down. When the pressing plate 5-5 presses the implant sponge, the acupuncture needle 1-3 moves and pierces into the cross opening of the sponge at the same time. At this time, the conveyor belt stops moving. The movement trajectory of the acupuncture needle 1-3 is as follows Figure 7 As shown, at this time, positive pressure airflow is introduced into the air inlet pipe 1-4 to blow the seeds of the acupuncture needles 1-3 into the cross opening, ensuring that the planting sponge does not move with the reciprocating motion of the acupuncture needles 1-3, thereby affecting the sowing position and subsequent sowing quality. When the pressing plate 5-5 moves upward and disengages from the planting sponge, the acupuncture needles 1-3 move upward synchronously, and the conveyor belt continues to move. The intermittent motion of the conveyor belt is controlled by a servo motor. The planting sponge is placed on the conveyor belt and moves under the drive of the conveyor belt to carry out the seeding operation at the next position. The box body 4-1 is fixedly mounted on a stand on the upper part of the conveyor belt and is fixedly connected to the stand to ensure that the entire acupuncture and seeding device is fixed. By changing the motor speed to adapt to different conveyor belt speeds and crops, the device punctures holes through the acupuncture needles 1-3 and seeds are planted while puncturing holes, thereby improving work efficiency.
