Description

Technical Field

[0001] The invention relates to the technical field of crop planting, and in particular to a seedling raising tray. Background Art

[0002] my country is a large agricultural country. Crops, especially rice, as a major food crop, affect the economic lifeline of the entire country. Due to the loss of rural labor and the aging of farmers, the planting of rice and other crops needs to develop in the direction of light simplification, scale and high yield. The use of seedling trays for crop seedling cultivation facilitates intensive management, is conducive to high and stable yield of crops, and the cost of seedling cultivation is lower than that of artificial seedling cultivation, which meets the requirements of agricultural modernization development.

[0003] At present, the common seedling trays on the market for rice, rapeseed and other crops are as follows: Figure 1 As shown, there are multiple seedling pots distributed on it, and the pot holes are distributed in rows and columns on the seedling tray. In order to adapt to the seedling retrieval mechanism of the mechanical transfer equipment, a certain width of spacing needs to be set between each row of pot holes on the seedling tray. The existence of this spacing will make the size of the seedling tray larger. This pot hole distribution method is easier to adapt to mechanized transplanting with fixed row and plant spacing, but there are still the following problems:

[0004] The width of the seedling tray is relatively large, and the ratio of the width of the seedling tray to the actual width occupied by the seedlings is also large, which makes the density of the seedlings low. A large seedling raising site is required for seedling raising, which is not conducive to management and has high intermediate costs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a seedling tray which can reduce the occupied space in view of the above-mentioned shortcomings.

[0006] The present invention is achieved through the following technical solutions:

[0007] A seedling tray comprises a tray body and a plurality of pot holes arranged on the tray body, wherein the tray body has a first direction and a second direction perpendicular to each other, and the plurality of pot holes are distributed in rows and columns along the first direction and the second direction; a gap portion is provided between any two adjacent columns of the pot holes in the second direction, and the gap portion is provided with a bending portion in the second direction.

[0008] Furthermore, the seedling raising tray also includes a connecting plate which is sleeved on the contracted seedling raising tray to fix its state, the connecting plate has a plurality of connecting holes which cooperate with the pot holes, and the plurality of connecting holes on the connecting plate are sleeved on the bottom of the plurality of pot holes of the contracted seedling raising tray along the first direction.

[0009] Furthermore, in the seedling raising tray, the bending portion passes through the tray body, and when the tray body contracts, the cross-section of the bending portion in the second direction is V-shaped, and the opening of the V-shape is in the same plane as the opening of the pot hole.

[0010] Furthermore, in the seedling raising tray, the bending portion has two first surfaces and two second surfaces opposite to the two first surfaces respectively, a first bending groove is arranged in the middle of the two first surfaces, and a second bending groove is arranged at the connection between the second surface and the tray body respectively; when the tray body (1) contracts, the two first surfaces move downward to form a V shape, and the opening of the V shape formed by the two first surfaces is in the same plane as the opening of the pot hole.

[0011] Furthermore, in the seedling raising tray, the first bending groove and the second bending groove penetrate the tray body in the second direction.

[0012] Furthermore, in the seedling tray, the tray body is made of a soft material that is bendable and resilient.

[0013] Furthermore, in the seedling raising tray, one side of the tray body and the other side edge opposite thereto are respectively provided with a male buckle and a female buckle which interlock with each other to connect the end to the end of the tray body after bending.

[0014] Furthermore, in the seedling raising tray, the tray body passes through the connecting tray at its ends after being bent, or the male buckle and the female buckle are connected to form a circular columnar structure, and the bottoms of several of the pot holes are located on the outer side of the circular columnar structure.

[0015] Furthermore, in the seedling raising tray, the bending portion is provided with air-avoiding holes arranged in a row along the first direction, and the air-avoiding holes are arranged at intervals from the pot holes distributed in a row along the first direction.

[0016] Furthermore, in the seedling raising tray, at least two opposite sides of the tray body are provided with flanges, and a plurality of notches are evenly arranged on the flanges.

[0017] The advantages and effects of the present invention are:

[0018] 1. The seedling tray provided by the present invention can be contracted / stretched. When raising seedlings, the seedling tray is in a contracted state, which can reduce the site area required for raising seedlings (actually reduced by more than 30%); when transplanting, the seedling tray is in an extended state, which can meet the seedling retrieval requirements of the transplanting machinery and is suitable for application in transplanting machinery.

[0019] 2. The tray body of the seedling tray provided by the present invention can be bent into a roll and then transported, thereby reducing the space occupied. The rolled seedling trays can be stacked during transportation, thereby improving space utilization, increasing the amount of transportation at one time, reducing labor costs, and improving transportation efficiency and operating efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0039] Figures 2 to 4The structural schematic diagram of the seedling tray provided by the embodiment of the present invention is shown. The seedling tray is used for planting seedlings of crops such as rice or rapeseed. The seedling tray can be used on a seedling raising machine or a seedling raising machine, and the seedling tray pots are covered with soil, sowed, covered with soil, sprinkled with water, etc., to realize mechanization or automation of seedling raising; after seedling raising, it can be used on a transplanting machine (such as a seedling throwing machine, a rice transplanting machine, a vegetable transplanting machine, etc.), and the seedling taking mechanism of the transfer machine takes the seedlings from the seedling tray, and then transplants (such as seedling throwing, transplanting, transplanting, etc.), to realize mechanization or automation of transplanting crop seedlings. The seedling tray includes a tray body 1 and a plurality of pots 2 arranged on the tray body 1. The tray body 1 has a first direction X and a second direction Y that are perpendicular to each other (for the convenience of description and understanding, they are named "first direction" and "second direction" respectively, and "first direction" and "second direction" are interchangeable in this article), and a plurality of pots 2 are distributed in rows and columns along the first direction X and the second direction Y. The distribution mode of the plurality of pots 2 is preferably but not limited to a matrix-type uniform arrangement. There is a gap 11 between any two adjacent rows of pot holes 2 in the second direction Y of the tray body 1. Preferably, the widths of the gaps 11 are the same. The gaps 11 can be bent by force to bring the two adjacent pot holes closer to each other, thereby reducing the area of ​​the seedling tray. Preferably, the gaps 11 are provided with a bending portion 12 in the second direction Y to shrink the seedling tray. The contraction and extension states of the bending portion 12 are shown in FIG. Figure 8 , as shown in 9. Figure 2 As shown, the tray body 1 may be a rectangle, and the two adjacent sides of the rectangular tray body are respectively located in the first direction X and the second direction Y, and a plurality of pot holes 2 are arranged in rows and columns along the rectangular tray body along the first direction X and the second direction Y. A plurality of pot holes adjacent to each other in the first direction X are a row, and a plurality of pot holes adjacent to each other in the second direction Y are a column, which is the same as the following text. The widths of a plurality of gaps between the pot holes in two adjacent columns may be the same, that is, they form a column of gaps that runs through the seedling tray. In the extended state, the distance between the pot holes in two adjacent columns is a (including the width of the gaps), a is the distance value that allows the seedlings to be taken out normally, and the distance between the pot holes in two adjacent rows is c.

[0040] The seedling raising tray also includes a connecting plate 5, that is, the seedling raising tray also includes a connecting plate 5 which is sleeved on the contracted seedling raising tray to fix its state, and the connecting plate 5 has a plurality of connecting holes 51 which cooperate with the pot holes 2, and the plurality of connecting holes 51 on the connecting plate (5) are sleeved on the bottom of the plurality of pot holes 2 of the contracted seedling raising tray along the first direction. Figure 5The structural schematic diagram of the connecting disk of the seedling tray provided by the embodiment of the present invention is shown. The connecting disk 5 is sleeved on the seedling tray after contraction to fix its state, and the connecting disk 5 has several connecting holes 51 that cooperate with the several pot holes 2 of the seedling tray and are of comparable size. The positions of the several connecting holes 51 on the connecting disk 5 correspond to the several pot holes 2 on the seedling tray after contraction. Preferably, two rows of connecting holes 51 are arranged on the connecting disk 5, and the connecting holes 51 correspond to the positions and quantities of the two rows of several pot holes 2 on the first direction X after contraction, and the two rows of pot holes 2 are sleeved into the two rows of connecting holes 51, which is convenient for fixing the state of the seedling tray. The connecting hole 51 can only include holes suitable for sleeved on the periphery of the pot hole 2, or it can also include a hole wall extending along the hole away from the connecting disk 5, or it can also include a hole bottom connected to the bottom of the hole wall. The connecting disk 5 can also realize the head-to-tail connection between two or more seedling trays, so that the positions of each row of pot holes of these seedling trays can be aligned, and more accurate sowing can be achieved when using a hand-push seedling raising machine, thereby improving the accuracy of the operation.

[0041] Figures 6 to 8 FIG. 2 is a schematic diagram showing a contracted state of a seedling tray provided in an embodiment of the present invention. Figure 6 As shown, in the contracted state, the distance between the pot holes in two adjacent columns is b (the gap is bent, and the width of the gap is not included at this time), and the distance between the pot holes in two adjacent rows is c. Figure 5 As shown, the distance between two adjacent rows of connecting holes 51 is equal to the distance c between two adjacent rows of bowl holes, and the distance between any two adjacent columns of connecting holes in each column is equal to the distance b between two adjacent columns of bowl holes in the contracted state, so that the positions of the connecting holes 51 of the connecting plate 5 can correspond one-to-one with the positions of the bowl holes 2 after the plate body 1 is folded, thereby achieving buckling. Figure 7 , 8 As shown, a plurality of connecting holes 51 on the connecting plate 5 are sleeved on the bottom of a plurality of pot holes 2 of the contracted seedling tray along the first direction X to maintain the contracted state of the seedling tray. If necessary, a plurality of connecting plates, preferably 3, can be provided on the contracted seedling tray. When it is necessary to raise seedlings, force is applied from both sides to the middle of the empty seedling tray along the first direction X, and the bending portion 12 of the gap portion 11 is bent. When the width between two adjacent rows of pot holes is compressed from a to b, a plurality of connecting plates 5 are used to be discretely buckled on the bottom of the pot holes 2 in the first direction X, so that the seedling tray can maintain a compressed state.

[0042] The bending portion 12 penetrates the plate body 1. When the plate body 1 is contracted, the cross section of the bending portion 12 in the first direction is V-shaped, and the opening of the V-shaped is in the same plane as the opening of the bowl hole 2. In the contracted state, the cross section of the bending portion 12 in the gap portion 11 in the second direction Y is in a bent shape, and the bent shape can be any shape such as W-shaped, V-shaped, etc. that is convenient for the contraction and expansion of the bending portion 12. Figure 8As shown in Figures 9 and 10, the bending portion 12 has two first surfaces 52 and two second surfaces 53 opposite to the two first surfaces 52, a first bending groove 54 is arranged in the middle of the two first surfaces 52, and a second bending groove 55 is arranged at the connection between the second surface 53 and the plate body 1; when the plate body 1 contracts, the two first surfaces 52 move downward to form a V-shape, and the opening of the V-shape formed by the two first surfaces 52 is in the same plane as the opening of the bowl hole 2. The first bending groove 54 is arranged in the middle of the two first surfaces 52 (i.e., the bottom of the angle of the V-shape formed when contracted, which can be on the perpendicular midline of the two adjacent bowl holes 2 of the first surface 52), and the second bending groove 55 is arranged at the connection between the second surface 53 and the plate body 1 (which can be near the two adjacent bowl holes 2), that is, there are two opposite second bending grooves 55. The bending grooves are provided for the convenience of bending. When the seedling tray is stretched, the first bending groove 54 moves downward under the action of force, and the two second bending grooves 55 move toward the middle, and finally the two first surfaces 52 are in a V-shaped state, so as to achieve the purpose of reducing the area of ​​the seedling tray. The first bending groove 54 and the two second bending grooves 55 penetrate the tray body 1 in the second direction Y respectively.

[0043] like Fig.10 , 11 As shown, the tray body 1 is a soft material that can bend and rebound. It can be deformed and bent within a certain range under the action of external force, can be folded, and can be connected end to end. After raising the seedlings, the seedling tray needs to be transported to the field or vegetable plot for transplanting. During transportation, the tray body 1 connected end to end after bending can stack multiple seedling trays with seedlings, thereby improving space utilization and increasing the one-time transportation volume. After bending, the tray body 1 is connected end to end to form a circular columnar structure, and the bottoms of several pot holes 2 are located on the outer side of the circular columnar structure. That is, the opening 21 of the pot hole 2 is located on the inner side of the circular columnar structure. Since the seedlings are all on the inner side of the circular columnar structure, the risk of the seedlings falling off the seedling tray during operation is reduced.

[0044] The disc body 1 can be bent in the first direction X or the second direction Y. To maintain the stability of the connection disc sleeved in the bowl hole, preferably, the disc body 1 is bent in the second direction Y, that is, the resilience of the gap portion acts on the high line of the annular columnar structure.

[0045] Fig.10 A schematic diagram of a curled embodiment 1 of the seedling tray provided by an embodiment of the present invention is shown. In the contracted state, the tray body 1 is bent in the second direction Y, and the two rows of connection holes of the connection disk 5 are respectively connected to the pot holes of the first and last rows, so that the contracted state of the seedling tray is maintained while the head and tail are connected. In order to maintain the stability of the contracted state of the seedling tray, at least two connection disks 5 are arranged on the circular columnar structure, that is, a connection disk 5 can be added to the unstable and deformed part of the circular columnar structure, and the two rows of connection holes of the connection disk 5 are respectively connected to the two rows of pot holes of the deformed part of the circular columnar structure.

[0046] Fig.11 , 12 A schematic diagram of Example 2 of a curled seedling tray provided in an embodiment of the present invention is shown. Fig.13 , 14 The male and female buckle structures provided by the embodiment of the present invention are shown; one side of the disk body 1 and the other side opposite thereto are respectively provided with a male buckle 6 and a female buckle 7 which are engaged with each other to connect the disk body 1 end to end after bending. Preferably, in the contracted or extended state, the disk body 1 is bent in the second direction Y, and the male buckle 6 and the female buckle 7 are respectively provided on the two sides of the disk body 1 in the first direction X. Specifically, as Fig.12 As shown, the male buckle 6 is in an inverted T-shaped structure, and a cross-shaped hole matching the T-shaped structure of the male buckle 6 is set in the middle of the female buckle 7. When the disc body 1 is bent until the head and tail ends are in contact, the wider part of the male buckle 6 (the upper "I"-shaped part of the T-shaped structure) can be inserted into the wider hole of the female buckle 7 (the "I"-shaped part of the cross-shaped structure), and then the narrower part of the male buckle 6 (the lower "I"-shaped part of the T-shaped structure) passes through the narrower hole of the female buckle 7 (the lower "I"-shaped part of the cross-shaped structure) so that the wider part of the male buckle 6 is clamped in the narrower hole of the female buckle 7, and the two are buckled together to form a structure as shown in FIG. Fig.11 The circular cylindrical structure shown. After the plate body 1 is bent, the ends are connected by the male buckle 6 and the female buckle 7 to form a circular cylindrical structure, and the bottoms of the plurality of pot holes 2 are located on the outer side of the circular cylindrical structure. The plate body 1, the male buckle 6 and the female buckle 7 can be, but are not limited to, an integrally formed structure. In order to maintain the stability of the seedling tray in the contracted state, one or more connecting plates 5 can also be provided on the circular cylindrical structure.

[0047] The bending portion 12 is provided with avoidance holes 3 in a row along the first direction, and the avoidance holes 3 are arranged at intervals with the pot holes 2 arranged in a row along the first direction. The interval arrangement means that a row of pot holes 2, a row of avoidance holes 3, a row of pot holes 2, a row of avoidance holes 3, and so on are arranged at intervals. Figure 2 As shown, an air-avoiding hole 3 is arranged between two adjacent gaps 11. The air-avoiding holes 3 are arranged in a row along the first direction X in the gaps between the bowl holes 2. The air-avoiding holes 3 are holes with a certain width that can make the bending part bend when the plate body 1 is connected end to end in the second direction Y. The air-avoiding holes 3 can be rectangular, square, waist-shaped, etc. Figure 7 As shown, when the seedling tray is in a contracted state, the setting of the air-avoiding holes makes the V-shaped area between two adjacent rows of pot holes discontinuous, so that the tray body 1 can bend in the second direction Y in the contracted state to achieve end-to-end connection.

[0048] At least two opposite sides of the tray body 1 are provided with flanges 4, and a plurality of notches 41 are evenly arranged on the flanges 4. The provision of flanges can increase the strength of the seedling tray and reduce the risk of it being torn during use. Figure 3 ,4 As shown in Figures 5 and 6, the two long sides of the tray body 1 are provided with flanges 4, that is, the flanges 4 are provided on the sides perpendicular to the folding direction (i.e., the sides in the second direction Y), so that when the seedling tray is sent into the seedling delivery mechanism of the transplanting machine (such as a rice throwing machine, a rice transplanting machine, or a vegetable transplanting machine), the seedling tray is stretched and sent between the pressing plate 82 and the conveying plate 81, and the flanges 4 on both sides can be stuck on the outside of the pressing plate 82 and the conveying plate 81, so that the seedling tray can be fully stretched out from the contracted state and stretched and fixed, meeting the seedling removal requirements of the transplanting machine (such as a rice throwing machine, a rice transplanting machine, or a vegetable transplanting machine). A plurality of notches 41 are evenly arranged on the flanges 4. The plurality of notches 41 can mesh with the teeth on the conveying wheel 8 of the seedling delivery part of the transplanting machine (such as a rice throwing machine, a rice transplanting machine, or a vegetable transplanting machine), and the rotation of the conveying wheel 8 drives the seedling tray to deliver the seedlings. Figure 5 The diagram shows the connection between the flange of the seedling tray and the conveying wheel provided by the embodiment of the present invention. The direction of the arc arrow is the rotation direction of the conveying wheel 8, and the direction of the straight arrow is the direction in which the seedling tray moves as the conveying wheel 8 rotates. Figure 3 When curling in the direction shown by the arrow, the notch provided on the flange 4 can make the flange bend smoothly and passively. The flange can be provided on all sides of the seedling tray. When the seedling tray provided with the flange needs to be provided with both the male buckle 6 and the female buckle 7, the male buckle 6 and the female buckle 7 can be provided on the flange.
