Description

Technical Field

[0001] The present invention relates to the technical field of Angelica sinensis transplantation, and particularly relates to a chain conveyor clamping device for transplanting Angelica sinensis seedlings. Background Art

[0002] During the planting process of Angelica sinensis, it is necessary to transplant the seedlings in the seedling tray into the planting land. The traditional transplantation method is mainly manual transplantation. This method is relatively traditional and labor-consuming, and is not suitable for large-scale planting patterns. Therefore, the existing Angelica sinensis transplantation method is mechanical transplantation;

[0003] For example, the patent application number CN202320546202.0 discloses a seedling cultivation and transplantation device. When using this seedling cultivation and transplantation device, take out the transplantation box 5, and at the same time squeeze the top of the adjusting plate 11 inward. The bottoms of the adjusting plates 11 move away from each other. Insert the bottoms of the adjusting plates 11 into the soil on both sides of the Angelica sinensis seedlings, and push the tops of the adjusting plates 11 to both sides, so that the bottoms of the adjusting plates 11 approach each other, and take in the Angelica sinensis seedlings and the soil into the soil collection groove. The transplantation box 5 can transfer the Angelica sinensis and the surrounding soil together, avoiding damage to the Angelica sinensis seedlings. Put this transplantation box 5 into the placement groove 8, and it can also directly cultivate the Angelica sinensis seedlings inside the transplantation box 5. Through the placement rack 3 and the vehicle body 1, the transplantation box 5 and the Angelica sinensis seedlings can be transplanted over a long distance, which can improve the transplantation efficiency of the Angelica sinensis seedlings; through the baffle 6, the bottom of the adjusting plate 11 can be limited, which is convenient for moving the soil and the Angelica sinensis seedlings. On the transplanted land, dig a pit in advance, put the soil and the Angelica sinensis seedlings into the pit, and the baffle 6 can also be pulled outwards so that the placement groove 8 is aligned with the pit. By pressing the tops of the adjusting plates 11 on both sides, it is convenient to discharge the soil and the Angelica sinensis seedlings, so that the soil and the Angelica sinensis seedlings fall into the pit.

[0004] Although this transplantation method in the prior art can achieve batch transplantation, there are many manual operation steps for workers, and it is difficult to achieve automatic transplantation, and there is still a problem of low efficiency. Summary of the Invention

[0061] The material taking assembly includes

[0062] Support plate 420, which is arranged on the mounting plate 100;

[0063] The movable plate 400 is movably arranged on the support plate 420;

[0064] The first lifting plate 500 is arranged on the movable plate 400 in a liftable manner;

[0065] A plurality of clamping plates 620 are respectively rotatably arranged on the lower surface of the first lifting plate 500, and the plurality of clamping plates 620 are arranged in a circular array;

[0066] The material receiving assembly 700 includes

[0067] The cross plate 730 is arranged on the side wall of the transmission chain 300, and a through hole 731 penetrating the cross plate 730 is formed on the cross plate 730;

[0068] The material receiving barrel 740 is arranged in the through hole 731, and the lower end of the material receiving barrel 740 is conical;

[0069] The material receiving barrel 740 includes

[0070] The first half barrel body 741 penetrates the through hole 731, and the outer wall of the upper port is fixedly connected to the inner wall of the through hole 731;

[0071] The fixing plate 742 is U-shaped, and the open end is fixedly connected to the outer walls on both sides of the first half barrel body 741. An extension plate 746 is provided at the upper end of the fixing plate 742;

[0072] The second half barrel body 743 is rotatably arranged on the inner side wall of the fixing plate 742, and both ends of the upper port of the second half barrel body 743 are provided with notches 744;

[0073] The second spring 745 has one end arranged on the outer wall of the second half barrel body 743 and the other end arranged on the extension plate 746;

[0075] A plurality of side plates 810 are respectively arranged on the upper port of the blanking pipe 800;

[0076] A plurality of second electromagnets 820 are respectively arranged on the side plates 810, and the second electromagnets 820 are used for adsorbing the second iron plate 750.

[0077] This embodiment is implemented as follows:

[0078] When this application is in use, place the seedling tray on the conveyor belt 200. The conveyor belt 200 sends the seedling tray to the position of the material taking component. Then, the moving plate 400 drives the first lifting plate 500 to move. Multiple clamping plates 620 on the first lifting plate 500 can follow the first lifting plate 500 and insert into the seedling grooves of the seedling tray. Then, the angelica seedling and soil in the seedling grooves are grabbed together. Then, the angelica seedling is moved above the material receiving component 700. The material receiving component 700 will move along with the transmission chain 300, so that multiple material receiving components 700 take turns to move below the material taking component. When the material receiving component 700 moves below the material taking component, the clamping plate 620 releases the angelica seedling, so that the angelica seedling falls into the material receiving bucket 740 of the material receiving component 700. Then, the transmission chain 300 drives the material receiving component 700 to move. When the angelica seedling moves above the blanking pipe 800, the second electromagnet 820 on the side plate 810 is activated. The second electromagnet 820 adsorbs the second iron plate 750, so that the second half barrel 743 rotates on the fixed plate 742. At this time, the second spring 745 is stretched. The material receiving bucket 740 formed by the first half barrel 741 and the second half barrel 743 opens. At this time, the angelica seedling falls into the blanking pipe 800, so that the angelica seedling falls into the planting hole. When the second electromagnet 820 is turned off, under the reset action of the second spring 745, the second half barrel 743 resets, and forms the material receiving bucket 740 with the first half barrel 741. In this application, the notch 744 on the second half barrel 743 can prevent the first half barrel 741 from blocking the rotation of the second half barrel 743.

[0079] It should be noted that the mounting plate 100 in this application is mainly mounted on an agricultural machine that can automatically dig planting holes, and the positions of the dug planting holes correspond to the positions of the blanking pipes 800, and the distances between adjacent planting holes and adjacent blanking pipes 800 are the same.

[0080] Please refer to Figure 1 、 2 As shown in Figures 6, 7, and 8, a driving roller 310 and a driven roller 330 are respectively rotatably arranged at the positions corresponding to the transmission chain 300 on the mounting frame 100. Tooth rings 320 are fixedly sleeved on both the driving roller 310 and the driven roller 330, and the transmission chain 300 meshes with the two tooth rings 320.

[0081] The driving roller 310 in this application is driven to rotate by a servo motor installed on the back of the mounting plate 100. The tooth ring 320 is driven to rotate by the driving roller 310, and the tooth ring 320 drives the transmission chain 300 to rotate.

[0082] Please refer to Figure 1 、 2 As shown in Figures 6, 7, and 8, a vertical plate 720 is fixedly connected to the side wall of the horizontal plate 730. Two connecting plates 710 are welded at the positions corresponding to the vertical plate 720 on the transmission chain 300, and the connecting plates 710 and the vertical plate 720 are connected by bolts.

[0083] The connecting plate 710 arranged on the transmission chain 300 can be fixedly connected to the vertical plate 720 on the cross plate 730 through bolts, so as to fix the cross plate 730 on the transmission chain 300.

[0084] Please refer to Figure 3 、 4 、5. A first iron plate 630 is fixedly connected to the clamping plate 620. Positioning plates 622 are respectively arranged on the first lifting plate 500 at positions corresponding to each clamping plate 620. A first rotating seat 621 is arranged at the lower end of the positioning plate 622. The clamping plate 620 is arranged in the U-shaped groove of the first rotating seat 621. The first iron plate 630 is connected to the corresponding positioning plate 622 through a first spring 631. The lower surface of the positioning plate 622 is fixedly connected with a first electromagnet 610 through a plurality of connecting rods 611. A plurality of first iron plates 630 surround the first electromagnet 610.

[0085] By starting the arranged first electromagnet 610, the first iron plate 630 can be adsorbed, so that the first iron plate 630 drives the clamping plate 620 to rotate on the first rotating seat 621. At this time, the first spring 631 is stretched, so that the ends of a plurality of clamping plates 620 are separated. After the clamping plate 620 is inserted into the seedling raising groove, it surrounds the angelica seedling. Then, after the first electromagnet 610 is turned off, under the reset action of the first spring 631, the first iron plate 630 is driven to reset, and the first iron plate 630 will drive the clamping plate 620 to rotate and reset, so that the clamping plate 620 clamps the roots and part of the soil of the angelica seedlings in the seedling raising groove.

[0086] Please refer to Figure 1 、 2 、3, 4, 5. A cross beam plate 520 is arranged on the moving plate 400. A first lifting cylinder 510 is arranged on the cross beam plate 520. The output end of the first lifting cylinder 510 is fixedly connected to the first lifting plate 500.

[0087] The arranged first lifting cylinder 510 can drive the first lifting plate 500 to move vertically on the cross beam plate 520 of the moving plate 400.

[0088] Please refer to Figure 1 、 2 ,A moving cylinder 410 is arranged on the support plate 420. The output end of the moving cylinder 410 is fixedly connected to the moving plate 400. A plurality of guide rods 430 that penetrate through the support plate 420 are arranged on the moving plate 400.

[0089] The moving cylinder 410 can drive the moving plate 400 to move on the support plate, and the guide rods 430 can increase the stability of the movement of the moving plate 400.

[0090] Please refer to Figure 1, a U-shaped limiting plate 210 is arranged on the conveyor belt 200, and the limiting plate 210 is made of elastic rubber material.

[0091] The limiting plate 210 on the conveyor belt 200 can facilitate the more accurate placement of the seedling tray position and has a reference function.

[0092] Please refer to Figure 1 、 9 , on both side walls of the mounting plate 100, support frames 832 are respectively arranged. Corresponding to the position of each blanking pipe 800, second lifting cylinders 831 are respectively arranged on the support frames 832. The output end of the second lifting cylinder 831 is fixedly connected with a second lifting plate 830, and the second lifting plate 830 is fixedly connected with the blanking pipe 800.

[0093] By setting the second lifting cylinder 831, it can drive the second lifting plate 830 to move vertically on the support frame 832, and then drive the blanking pipe 800 to move vertically, so that the blanking pipe 800 can keep a certain distance from the ground.

[0094] Please refer to Figure 9 、 10 , a soil covering structure is further arranged at the lower end of the blanking pipe 800. The soil covering structure includes an iron ring 910 sleeved on the outer circumferential wall of the blanking pipe 800 and capable of lifting. The iron ring 910 is frustum-shaped. A number of second rotating seats 960 arranged in an annular shape are arranged on the outer circumferential wall of the blanking pipe 800. A soil pushing plate 950 is connected to the second rotating seat 960. The upper end of the soil pushing plate 950 is connected with the outer wall of the blanking pipe 800 through a fourth spring 970.

[0095] By the downward movement of the blanking pipe 800, it can drive the soil pushing plate 950 to insert into the soil around the planting hole. Then the iron ring 910 moves downward, so that the arc surface of the iron ring 910 can insert into the gap between the upper end of the soil pushing plate 950 and the outer wall of the blanking pipe 800, causing the iron ring 910 to push the soil pushing plate 950 to rotate. At this time, the fourth spring 970 is stretched, and the lower end of the soil pushing plate 950 will move towards the planting hole, thereby pushing the soil into the planting hole to complete soil covering. When the iron ring 910 returns to its original position, under the reset action of the fourth spring 970, the soil pushing plate 950 will reset.

[0096] Please refer to Figure 9 、 10 , a fixing ring 940 is fixedly sleeved on the outer circumferential wall of the blanking pipe 800. The fixing ring 940 is connected with the iron ring 910 through a number of third springs 920. A third electromagnet 930 is arranged on the fixing ring 940.

[0097] After the third electromagnet 930 is activated, it can attract the iron ring 910, causing the third spring 920 to be compressed. At this time, the iron ring 910 moves away from the bulldozing plate 950. When the third electromagnet 930 is turned off, under the reset action of the third spring 920, the iron ring 910 moves downward, causing the iron ring 910 to push the bulldozing plate 950 to rotate.

[0098] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
