Description

Technical Field

[0001] The utility model relates to the technical field of seedling transplanting equipment, in particular to a seedling planting and feeding device and a seedling transplanting machine. Background Art

[0002] In modern agricultural production, seedling transplanting is a common agronomic operation, which refers to the process of taking out seedlings from the seedbed, and after appropriate treatment, transplanting them into the prepared soil.

[0003] In order to improve the efficiency of seedling transplanting and the degree of automation of seedling transplanting, people usually use a seedling transplanting machine to achieve seedling transplanting. Before the seedlings of the seedling transplanting machine are sent into the soil for planting, they generally pass through a cultivation cup to realize seedling feeding. In order to improve the survival rate of seedling transplanting and promote the rapid growth of seedlings, fertilizers are often scattered at the position where the seedlings are transplanted during seedling transplanting, that is, fertilization. The existing fertilization method is mainly manual. After the seedlings are transplanted, fertilizers are manually scattered into the transplanting position. This method has a large labor intensity, low automation degree and low efficiency, and is not conducive to the use of large-scale transplanting of seedlings. Another method is to use fertilization equipment to achieve fertilization through an automated or semi-automated method. The labor intensity is low, but additional fertilization equipment is required, and the cost is relatively high. And it is generally carried out after seedling transplanting, independent of the seedling transplanting method, which is not conducive to shortening the entire operation time, and also requires dedicated operating personnel, which is not conducive to reducing labor costs.

Therefore, it should not be construed as a limitation to the present utility model.

[0045] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0046] Please refer to Figures 1 to 9 , a preferred embodiment of the present utility model provides a seedling planting and feeding device, which includes a seedling feeding cavity 10, a cultivation cup 20, a reset member 30, a temporary storage cavity 40, a driving member 50, and a material bin 60.

[0047] The seedling feeding cavity 10 is used to hold the seedlings to be planted, and both the top and bottom of the seedling feeding cavity 10 are open. During implementation, the seedling feeding cavity 10 is fixedly installed on the seedling transplanting machine and is used to receive the seedlings sent by the seedling transplanting machine. The seedlings enter through the open top of the seedling feeding cavity 10. The seedling feeding cavity 10 is a cylindrical hollow structure as a whole. The seedling feeding cavity 10 is fixedly installed on the mounting plate 70. During use, the mounting plate 70 is fixedly installed on the seedling transplanting machine.

[0048] The cultivation cup 20 is arranged at the bottom of the seedling feeding cavity 10 so that when the cultivation cup 20 is closed, it can block the bottom of the seedling feeding cavity 10. At this time, when the seedlings enter the seedling feeding cavity 10, if the cultivation cup 20 is in the closed state, it will block the bottom of the seedling feeding cavity 10. Please refer to Figure 1 , at this time, the seedlings will be located in the cultivation cup 20 and will not fall out from the bottom of the seedling feeding cavity 10. Of course, it can be understood that if the seedlings have a certain height and are higher than the cultivation cup 20, at this time, it can also be understood that the seedlings are located in the seedling feeding cavity 10; correspondingly, when the cultivation cup 20 is in the open state, it will not block the bottom of the seedling feeding cavity 10. Please refer to Figure 2 , at this time, the seedlings will fall out from the bottom of the seedling feeding cavity 10 and fall into the dug seedling pits, thereby realizing seedling transplantation.

[0049] The reset member 30 is installed between the cultivation cup 20 and the seedling feeding cavity 10 so that the cultivation cup 20 has a tendency to close. That is, under the action of the reset member 30, the cultivation cup 20 has a tendency to close. When no external force acts, the cultivation cup 20 closes, or when the cultivation cup 20 is opened and the external force is removed, the cultivation cup 20 closes again under the action of the reset member 30.

[0050] The driving member 50 is used to push against the cultivation cup 20 to be able to drive the cultivation cup 20 to open. That is, through the action of the driving member 50, it can push against the cultivation cup 20 to be able to drive the cultivation cup 20 to open. The pushing force of the driving member 50 can be used as the external force for the cultivation cup 20 to open, so that the cultivation cup 20 opens at an appropriate time, thereby realizing seedling feeding, that is, realizing seedling transplanting. The driving member 50 is fixedly installed on the mounting plate 70.

[0051] A material bin discharge port 61 is provided at the bottom of the material bin 60, and the material bin discharge port 61 penetrates into the seedling feeding cavity 10. The material bin 60 is used for temporarily storing fertilizers, and the fertilizers are mainly granular fertilizers. The fertilizers are temporarily stored in the material bin 60 and can be sent into the seedling feeding cavity 10 through the material bin discharge port 61, and can fall out of the seedling feeding cavity 10 when the cultivation cup 20 is opened. The material bin 60 is fixedly installed on the mounting plate 70.

[0052] The temporary storage cavity 40 is installed in the seedling feeding cavity 10 and is driven by the driving member 50 to move up and down. Refer to Figure 5 、 Figure 8 and Figure 9 , and an opening 41 of the temporary storage cavity is provided on one side of the temporary storage cavity 40 so that when the temporary storage cavity 40 moves up and down to a certain position, the opening 41 of the temporary storage cavity is aligned with the material bin discharge port 61 to be able to send the materials in the material bin 60 into the temporary storage cavity 40 through the material bin discharge port 61. At this time, the materials (fertilizers) in the material bin 60 enter the temporary storage cavity 40 through the material bin discharge port 61 and are temporarily stored in the temporary storage cavity 40. It can be understood that the volume of the temporary storage cavity 40 is smaller than the volume of the material bin 60, and a small part of the fertilizers in the material bin 60 enters the temporary storage cavity 40 and fills the temporary storage cavity 40 to a certain extent.

[0053] Refer to Figure 5 、 Figure 6 and Figure 7A temporary storage cavity discharge port 42 is provided on one side of the temporary storage cavity 40 so that the material in the temporary storage cavity 40 can go out through the temporary storage cavity discharge port 42 and fall into the seedling cavity 10. That is, by providing the temporary storage cavity discharge port 42, the fertilizer can leave the temporary storage cavity 40 from the temporary storage cavity discharge port 42 and enter the seedling cavity 10. The fertilizer in the seedling cavity 10 can fall out of the seedling cavity 10 when the cultivation cup 20 is opened, and temporarily remain in the seedling cavity 10 when the cultivation cup 20 is closed.

[0054] A blocking plate 11 is fixedly provided in the seedling planting cavity 10 so that when the temporary storage cavity 40 moves up and down to a certain position, the blocking plate 11 can block the temporary storage cavity discharge port 42. That is, when the driving member 50 drives the temporary storage cavity 40 to move to a certain position, the temporary storage cavity discharge port 42 is opposite to the blocking plate 11, thereby blocking the temporary storage cavity discharge port 42. At this time, the fertilizer in the temporary storage cavity 40 cannot come out from the temporary storage cavity discharge port 42.

[0055] During implementation, the seedlings enter the seedling cavity 10 from the top opening of the seedling cavity 10. At this time, the cultivation cup 20 is in a closed state. Under the action of the cultivation cup 20, the seedlings are temporarily located in the cultivation cup 20 or in the seedling cavity 10. When the seedling transplanter drives the seedling planting and seedling feeding device to move above the seedling planting position, the driving member 50 pushes the cultivation cup 20 to drive the cultivation cup 20 to open. At this time, the seedlings are thrown from the cultivation cup 20 into the seedling cavity 10. The fertilizer is temporarily stored in the material bin 60 and is fed into the temporary storage cavity 40 through the material bin outlet 61 and is temporarily stored in the temporary storage cavity 40. When the temporary storage cavity outlet 42 is offset from the blocking plate 11, the fertilizer in the temporary storage cavity 40 comes out of the temporary storage cavity outlet 42 and enters the seedling cavity 10. When the cultivation cup 20 is opened, the fertilizer falls down and falls out of the seedling cavity 10 and the cultivation cup 20 to achieve fertilization. The seedling planting seedling feeding device of the utility model can realize the seedling feeding to realize the seedling transplanting. At the same time, during the transplanting process, it can also realize feeding, that is, fertilization, and realize the transplanting and fertilization of seedlings together, thereby improving the transplanting efficiency, integrating the seedling feeding equipment with the fertilization equipment, improving the integration and automation of the transplanting equipment, reducing the labor intensity, shortening the transplanting operation time, reducing the number of operators required, and reducing labor costs.

[0056] The cultivation cup 20 includes a plurality of cultivation cup unit pieces 21. The plurality of cultivation cup unit pieces 21 are arranged in a surrounding manner so that the cultivation cup 20 can form a downward conical structure. The top of the cultivation cup unit piece 21 is hinged to the bottom of the seedling throwing cavity 10. When each cultivation cup unit piece 21 is opened outwards, the cultivation cup 20 is opened at this time. When each cultivation cup unit piece 21 is folded inwards, the cultivation cup 20 is closed. The cultivation cup unit piece 21 is connected to the bottom of the seedling throwing cavity 10 through a hinge 22 to achieve mutual hinge. The reset member 30 is a torsion spring. The two ends of the hinge 22 extend outwards to form an extension shaft 23. The reset member 30 that is a torsion spring is sleeved on the extension shaft 23, and the two ends of the reset member 30 that is a torsion spring respectively abut against the cultivation cup unit piece 21 and the seedling throwing cavity 10. Through the reset member 30 that is a torsion spring, the cultivation cup unit piece 21 has a tendency to close and reset after being unfolded. In this exemplary embodiment, there are two cultivation cup unit pieces 21, which are arranged oppositely. When the two cultivation cup unit pieces 21 are closed, they can form a downward conical structure.

[0057] The driving member 50 is preferably an electric push rod. The bottom end of the telescopic rod of the driving member 50 that is an electric push rod abuts against the inner side of the cultivation cup unit piece 21. The telescopic rod of the driving member 50 that is an electric push rod is arranged vertically, and the telescopic rod faces downwards and vertically expands and contracts. When the telescopic rod of the driving member 50 that is an electric push rod extends downwards, it pushes down the cultivation cup unit piece 21 to realize the opening of the cultivation cup unit piece 21. When the telescopic rod of the driving member 50 that is an electric push rod retracts upwards, the cultivation cup unit piece 21 closes and resets under the action of the reset member 30 that is a torsion spring.

[0058] For reference, Figure 6 and Figure 8 The temporary storage cavity 40 is fixedly installed on the telescopic rod of the driving member 50 that is an electric push rod to move up and down with the telescopic rod of the driving member 50 that is an electric push rod. The temporary storage cavity 40 is fixedly provided with a connecting sleeve 45, and the connecting sleeve 45 is fixedly installed on the telescopic rod of the driving member 50 that is an electric push rod. The top surface of the temporary storage cavity 40 is open. When the fertilizer is fed into the temporary storage cavity 40 through the discharge port 61 of the material bin, it is convenient to avoid the relatively high closed pressure of the temporary storage cavity 40, which is not conducive to the smooth entry of the fertilizer. The form of the temporary storage cavity 40 with an open top surface can also ensure that the fertilizer will not fall from the open port after entering the temporary storage cavity 40.

[0059] In a preferred embodiment, as Figures 5 to 9As shown, the temporary storage cavity opening 41 is opened at the upper side of the temporary storage cavity 40, and the side is the side facing the material bin discharge port 61. In this exemplary embodiment, the temporary storage cavity 40 is a square structure as a whole, and the four sides are straight sides. One of the sides is provided with a connecting sleeve 45, and the connecting sleeve 45 is connected to the driving member 50 through a key so that the temporary storage cavity 40 can only move up and down under the drive of the driving member 50 but cannot rotate; the temporary storage cavity opening 41 is opened at the side opposite to the side where the connecting sleeve 45 is located, and is located at the upper part of the side. At this time, the material bin discharge port 61 feeds from the upper part of the temporary storage cavity 40 when feeding. The temporary storage cavity discharge port 42 is opened at the lower part of the side of the temporary storage cavity 40. At this time, the fertilizer temporarily stored in the temporary storage cavity 40 goes out from the lower part of the side of the temporary storage cavity 40, which can facilitate the discharge of the fertilizer.

[0060] Please refer to Figure 8 and Figure 9 , the side of the temporary storage cavity 40 is fitted to the open end face of the material bin discharge port 61, and when the temporary storage cavity 40 moves downward so that the temporary storage cavity opening 41 is directly opposite to the material bin discharge port 61 to achieve material feeding, the blocking plate 11 aligns with and blocks the temporary storage cavity discharge port 42 to prevent material discharge. At this time, the temporary storage cavity 40 only feeds but does not discharge. While the temporary storage cavity 40 moves downward, at the same time, the telescopic rod of the driving member 50 of the electric push rod extends downward to push the cultivation cup unit piece 21 to open the cultivation cup unit piece 21 outward. Please refer to Figure 6 and Figure 7 When the temporary storage cavity 40 moves upward so that the side of the temporary storage cavity 40 fits with the material bin discharge port 61 to prevent material from entering, the blocking plate 11 is staggered with the temporary storage cavity discharge port 42 to achieve discharge. At this time, the temporary storage cavity 40 only discharges material but does not feed material. In order to avoid the situation where the temporary storage cavity opening 41 is staggered with the material bin discharge port 61 when the temporary storage cavity 40 moves upward, and fertilizer may flow out of the temporary storage cavity opening 41, please refer to Figures 4 to 9, a blocking plate 63 is provided extending upward from the upper part of the port of the material bin discharge port 61. When the temporary storage cavity 40 moves upward, the open end 41 of the temporary storage cavity at its upper part will abut against the blocking plate 63, thus ensuring that the fertilizer in the temporary storage cavity 40 will not come out from the open end 41 of the temporary storage cavity. The temporary storage cavity 40 moves upward. At the same time, as the telescopic rod of the driving member 50 of the electric push rod resets upward, the cultivation cup unit piece 21 closes and resets under the action of the reset member 30 which is a torsion spring. Through this structural arrangement, it is possible to temporarily store the fertilizer in the cultivation cup 20 of the seedling planting cavity 10, and when the seedling is sent into the seedling planting cavity 10 and the cultivation cup 20 is opened, it will fall together with the seedling, ensuring that the falling positions of the seedling and the fertilizer are basically the same. Considering that if the driving member 50 pushes the cultivation cup 20 to open and then the fertilizer starts to come out from the temporary storage cavity 40 and fall downward, due to the limited size of the discharge port 42 of the temporary storage cavity 40 of the temporary storage cavity, it is difficult to discharge quickly, and there is a certain distance between the temporary storage cavity 40 and the bottom of the cultivation cup 20, and it also takes a certain time for the material to fall. In order to ensure the transplanting efficiency, during seedling planting, the seedling transplanting machine basically does not stop. Then, in the case where the seedling transplanting machine does not stay, if there is a certain height difference between the discharge of the fertilizer and the discharge of the seedling, the fertilizer often falls in a linear distribution form behind the seedling planting position, which is not conducive to effective fertilization.Based on this, in the present utility model, when the telescopic rod of the driving member 50 of the electric push rod resets upward, the cultivation cup unit piece 21 closes and resets under the action of the reset member 30 which is a torsion spring, and the cultivation cup 20 closes. At the same time, during this process, when the temporary storage cavity 40 moves upward with the driving member 50, the side surface of the temporary storage cavity 40 fits with the discharge port 61 of the material bin to prevent feeding. When the blocking plate 11 is staggered from the discharge port 42 of the temporary storage cavity to achieve discharging, at this time, the temporary storage cavity 40 only discharges and does not feed. That is, when the cultivation cup 20 closes, the fertilizer temporarily stored in the original temporary storage cavity 40 is discharged through the discharge port 42 of the temporary storage cavity and falls into the cultivation cup 20; then the seedlings are sent into the seedling throwing cavity 10 and fall into the cultivation cup 20 to wait for seedling throwing. When the cultivation cup 20 moves to the planting position with the seedling raising and transplanting machine, the telescopic rod of the driving member 50 of the electric push rod extends downward to push the cultivation cup unit piece 21 to open outward, and at this time the seedlings fall downward to achieve transplantation, and the fertilizer temporarily stored in the cultivation cup 20 also falls with the seedlings to achieve fertilization. Since the seedlings and the fertilizer fall at the same position, the falling positions are basically the same, which can ensure the effectiveness of fertilization when realizing seedling transplantation. When the telescopic rod of the driving member 50 of the electric push rod extends downward, it simultaneously drives the temporary storage cavity 40 to move downward so that the open end 41 of the temporary storage cavity is aligned with the discharge port 61 of the material bin to achieve feeding, that is, the fertilizer is sent into the temporary storage cavity 40. At this time, the blocking plate 11 aligns with and blocks the discharge port 42 of the temporary storage cavity to prevent discharging. At this time, the temporary storage cavity 40 only feeds and does not discharge. The fertilizer temporarily stored in the temporary storage cavity 40 this time can also go out through the discharge port 42 of the temporary storage cavity and fall into the cultivation cup 20 when the telescopic rod of the driving member 50 of the electric push rod resets upward to close the cultivation cup 20, waiting to be fertilized together when the next batch of seedlings are thrown.

[0061] As Figure 5 shown, a plurality of vertically extending placement grooves 46 are provided in the temporary storage cavity 40. Each group of placement grooves 46 has two vertically extending placement grooves 46. The two vertically extending placement grooves 46 of each group of placement grooves 46 are opened on the inner walls of the opposite side surfaces of the temporary storage cavity 40. The opposite side surfaces of the temporary storage cavity 40 are the side surfaces not provided with the open end 41 of the temporary storage cavity and the connecting sleeve 45. The plurality of vertically extending placement grooves 46 are arranged in sequence from near the open end 41 of the temporary storage cavity to far away from the open end 41 of the temporary storage cavity. A partition plate 47 is vertically inserted in one group of placement grooves 46. The partition plate 47 divides the temporary storage cavity 40 into two chambers. Among them, the chamber near the open end 41 of the temporary storage cavity is communicated with the open end 41 of the temporary storage cavity to achieve the entry of fertilizer, while in the other chamber, the fertilizer will not enter. At this time, by adjusting the partition plate 47 in each group of placement grooves 46 at different positions, the size of the chamber into which the fertilizer enters is adjusted. The space for storing the fertilizer in different-sized chambers is certain, so that the amount of fertilizer for each fertilization can be adjusted.

[0062] On the side of the temporary storage cavity 40, there is a vertically extending guide bar 43. On the open end face of the discharge opening 61 of the material bin and the sealing plate 11, there are respectively guide rails 44 that match the guide bar 43. By setting the guide bar 43 and the guide rails 44, under the cooperative action of the guide bar 43 and the guide rails 44, it is ensured that the temporary storage cavity 40 does not deviate during the movement process, so as to ensure accurate feeding and discharging.

[0063] The bottom of the temporary storage cavity 40 is inclined such that the position close to the discharge opening 42 of the temporary storage cavity is lower and the position far from the discharge opening 42 of the temporary storage cavity is higher, so as to facilitate the discharge of the fertilizer in the temporary storage cavity 40 through the discharge opening 42 of the temporary storage cavity.

[0064] In order to achieve automatic feeding, the material bin 60 is higher than the temporary storage cavity 40. The bottom of the material bin 60 is conical, and there is a feeding pipeline 62 extending obliquely downward at the bottom of the material bin 60. The discharge opening 61 of the material bin is opened at the end of the feeding pipeline 62. In this way, by the self-weight of the fertilizer, it automatically moves towards the discharge opening 61 of the material bin and enters the temporary storage cavity 40.

[0065] Considering that there are multiple cultivation cup unit pieces 21, the corresponding number of driving members 50 can be used to drive the cultivation cup unit pieces 21 one by one. At this time, each driving member 50 can also be correspondingly equipped with a set of temporary storage cavities 40, material bins 60, etc. For example, in this exemplary embodiment, there are two cultivation cup unit pieces 21, then two driving members 50 can be set. The two driving members 50 operate simultaneously, and each driving member 50 is correspondingly equipped with a set of temporary storage cavities 40 and material bins 60 to achieve double-bin feeding. The same fertilizer or different fertilizers can be placed in each material bin 60. Of course, it can be understood that even if multiple material bins 60 are set, feeding can also be achieved only through one or some of the material bins 60, which can be specifically selected according to actual needs.
