Description

Technical Field

[0001] The present invention relates to the technical field of pumpkin seedling raising, and particularly relates to a method for batch constant-temperature seedling raising of pumpkin seeds. Background Art

[0002] After the soaking and germination of pumpkin seeds are completed, constant-temperature seedling raising needs to be carried out first, and then the seeds are transplanted to the field after growing into seedlings. The current seedling raising methods are mainly as follows: it is necessary to first prepare a seedling raising substrate, then pour the seedling raising substrate into each planting groove in the tray, and then insert the germinated pumpkin seeds one by one into each planting groove. Place the tray in the greenhouse, spray water regularly, and ensure that the temperature in the greenhouse is constant.

[0003] The above traditional seedling raising methods often have the following deficiencies in actual operation:

[0004] 1. During the seedling raising process, workers need to insert the seeds into the planting grooves one by one. Bending down for a long time is very tiring and the efficiency is low.

[0005] 2. When inserting the seeds, there is a probability that the small buds on the seeds will be squeezed and broken.

[0006] 3. When sowing manually, the placement position and depth of the seeds cannot be guaranteed, and the production uniformity is insufficient.

[0007] Therefore, to solve the above problems, the present invention provides a method for batch constant-temperature seedling raising of pumpkin seeds with high efficiency and low damage. Summary of the Invention

[0038] In S3.2, specifically: when the driving rod drives the cover plate to move downward, the soil-opening assembly is inserted into the receiving box until the retaining ring contacts the top of the receiving box. At the same time, the retaining frame contacts the retaining plate and moves outward to lengthen the bidirectional spring rod. The convex box is inserted into the receiving box and pushes the inclined elastic clip outward to a vertical state. The soil-opening plate in the combined state is inserted into the seedling medium.

[0043] In S5.2, two sets of handle frames are placed between two sets of expansion plates, and the inclined surfaces of the right-angle plates slide and fit with the outer ends of the clamping rod groups; when the handle frames are pressed down, the right-angle plates resist the outward movement of the clamping rod groups and drive the clamping columns to move outward, so that the two sets of elastic clamps open to facilitate the removal of the pumpkin seedlings with substrate.

[0044] The present invention provides a method for batch constant-temperature seedling raising of pumpkin seeds. Compared with the prior art, it has the following beneficial effects:

[0045] 1. Place the lifting component on the annular conveyor belt. The annular conveyor belt can drive each group of lifting components to pass through the substrate placement area and the seed placement area one by one. In this way, the operator only needs to complete the seedling raising operation at one position, without adding soil and seeds into the trays one by one. The labor intensity of the workers is smaller, and the seed insertion efficiency is higher, which can meet the needs of large-scale pumpkin seed operations; and the lifting components can be directly stacked on the annular conveyor belt without subsequent manual stacking;

[0046] 2. The soil-opening component can extend down into the seedling raising substrate in the accommodation box, so as to automatically open the placement holes. When the worker releases the seeds, the seeds can automatically fall into the placement holes, realizing that each seed can be placed at the center position and the specified depth of the accommodation box, ensuring the uniformity of the seeds placed in each accommodation box, and further ensuring that the seeds are in the best covering environment. At the same time, the whole process will not damage the young buds, improving the growth qualification rate;

[0047] 3. The setting of the bearing component can achieve the following effects:

[0048] 3.1 After the seeds are placed, the bearing component can retract inward to compact the substrate, so that the placement holes are closed, and the seeds can be automatically sealed in the substrate;

[0049] 3.2 When the seedling raising is completed, the pumpkin seedlings and the substrate are both above the bearing component. Since the root systems of the seedlings are integrated with the substrate, when the worker lifts the bearing component, the substrate and the pumpkin seedlings can be taken out together without damaging the root hairs and with higher efficiency;

[0050] 3.3 During the transfer, the bearing component can protect the seedlings from the outside, facilitating the subsequent transfer operation of transplanting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0068] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] Embodiment 1

[0070] In order to solve the technical problems in the background technology, a method for batch constant temperature seedling cultivation of pumpkin seeds is provided as follows:

[0071] Combination Figures 1 - 15 As shown, the present invention provides a method for batch constant temperature seedling cultivation of pumpkin seeds, and the seedling cultivation method comprises the following steps:

[0072] S1. Seedling preparation: The sprouted pumpkin seeds are transferred to the heat preservation greenhouse 1. A plurality of groups of annular conveyor belts 2 are arranged in the annular greenhouse. A plurality of groups of lifting components 3 are arranged on the annular conveyor belts 2. Each group of lifting components 3 is built with a plurality of groups of receiving boxes 6. The worker inserts the bearing components 5 into the receiving boxes 3 in the bearing rack placement area 21.

[0073] S2, a worker adds a seedling culture medium into each receiving box 6 of the holding assembly 3 in the medium placement area 22;

[0074] S3, soil opening and seed placement: S3.1, the endless conveyor belt 2 drives the lifting assembly 3 to the seed placement area 23; S3.2, the soil opening assembly 7 in the seed placement area 23 moves downward and is inserted into the receiving box 3 to open a placement hole 9 in each receiving box 6; S3.3, the operator throws pumpkin seeds into each placement hole 9; S3.4, the soil opening assembly 7 is lifted to drive the bearing assembly 5 to compact and close the placement hole 9, so that the placed pumpkin seeds are fully covered by the seedling medium;

[0075] S4, heat preservation seedling cultivation; the electric heating wire at the bottom of the circular conveyor belt 2 heats the holding component 3, so that the pumpkin seeds are in a constant temperature environment of 28℃-32℃; the spray rack at the top of the circular conveyor belt 2 regularly sprays the holding component 3;

[0076] S5. Transplanting: S5.1. After the pumpkin seeds grow into pumpkin seedlings, lift the supporting component 5, which drives the seedling-raising matrix and the pumpkin seedlings to separate from the lifting component 3; S5.2. Peel off the pumpkin seedlings with the matrix from the supporting component 5; S5.3. Transplant the pumpkin seedlings with the matrix into outdoor soil.

[0077] In the above scheme:

[0078] 1. Place the lifting components on the circular conveyor belt. The circular conveyor belt can drive each group of lifting components to pass through the substrate placement area and the seed placement area one by one. In this way, the operator only needs to complete the seedling operation in one position, without adding soil and placing seeds in the tray one by one. The labor of the workers is less, and the seed insertion efficiency is higher, which can meet the needs of large-scale pumpkin seed operations; and the lifting components can be directly stacked on the circular conveyor belt without the need for subsequent manual stacking;

[0079] 2. The soil-opening component can be lowered into the seedling matrix of the receiving box to automatically open a placement hole. When the worker loosens the seed, the seed will automatically fall into the placement hole, so that each seed can be placed in the center of the receiving box and at a specified depth, ensuring the uniformity of the seeds placed in each receiving box, thereby ensuring that the seeds are in the best covering environment. At the same time, the whole process will not damage the young sprouts, thereby improving the qualified growth rate;

[0080] 3. The setting of the bearing component can achieve the following effects:

[0081] 3.1. After the seeds are placed, the bearing assembly can be retracted to compact the matrix so that the placement hole is closed, so that the seeds can be automatically sealed in the matrix;

[0082] 3.2. When the seedlings are grown, the pumpkin seedlings and the matrix are all above the supporting components. Since the seedling roots are connected to the matrix, workers can lift the supporting components to take out the matrix and pumpkin seedlings together, without damaging the roots and with higher efficiency.

[0083] 3.3. During transfer, the carrying component can protect the seedlings from the outside, facilitating the subsequent transfer operation for transplanting.

[0084] Embodiment 2

[0085] In order to enable the lifting component and the carrying component to achieve the above efficiency, the following solution is given in this embodiment:

[0086] In this embodiment, the lifting component 3 includes a base 31, baffles 32, a bi-directional spring rod 33 and a support column 34. The base 31 is a rectangular box structure. The surface of the base 31 is provided with lower openings 411 arranged in a rectangle. A set of receiving boxes 6 are fixedly installed in each lower opening 411. The upper half of the receiving box 6 extends out of the lower opening 411, and the lower half is placed inside the receiving box 6. Baffles 32 are symmetrically installed on both sides of each lower opening 411. The bottom end of the baffle 32 is slidably installed on the inner bottom surface of the receiving box 6. The bottom surface of the receiving box 6 is provided with a bi-directional spring rod 33. The outer end of the bi-directional spring rod 33 is connected to the bottom inner wall of the baffle 32. A support column 34 is provided at the center of the bottom surface of the base 31, and the support column 34 is arranged on the annular conveyor belt 2.

[0087] In the above solution:

[0088] 1. Design the bottom surface of the base to support the support column at a single point, which can facilitate the annular conveying.

[0089] 2. The baffle can cooperate with the bi-directional spring rod to achieve elastic displacement. When the soil-opening component is inserted, it can push two groups of baffles outwards and stretch the bi-directional spring rod. In this way, it can prepare for the subsequent pressing. When the soil-opening component leaves, the bi-directional spring rod drives the baffle to retract and reset, and the baffle can squeeze the carrying component to retract and reset to compact the substrate.

[0090] In this embodiment, the carrying component 5 includes a handle frame 51, a clamping rod group and an elastic support cover 55. There are two groups of handle frames 51 symmetrically arranged. The handle frame 51 is in an inverted U shape. Two groups of clamping rod groups are symmetrically arranged between the two groups of handle frames 51. Horizontal chutes 52 are opened on the two outer extending parts of the handle frame 51. The ends of the clamping rod group are slidably embedded in the chutes 52. A plurality of elastic support covers 55 are clamped between the two groups of clamping rod groups. The clamping rod group is placed outside the receiving box 6, and the baffle 32 is placed outside the clamping rod group.

[0091] In S1, when the carrying component 5 is inserted into the lifting component 3, the elastic support cover 55 is embedded in the receiving box 6. The bottom of the elastic support cover 55 fits on the inner bottom surface of the receiving box 6, and the handle frame 51 is placed on the surface of the base 31. In S5.1, the handle frame 51 is lifted upwards, and the elastic support cover 55 lifts the pumpkin seedlings with the substrate.

[0092] In the above solution;

[0093] 1. The elastic support cover is designed as the main supporting structure for the substrate and seedlings. Initially, it can be inserted into the accommodation box, and the whole elastic support cover is embedded in the inner bottom surface of the accommodation box. In this way, when adding the substrate subsequently, the substrate can be filled into the accommodation box to ensure the filling amount of the substrate. At the same time, part of the substrate and seeds are placed on the elastic support cover, which is convenient for subsequent clamping and lifting.

[0094] 2. The handle frame is provided to facilitate the workers to pick up and transfer.

[0095] 3. The handle frame can be used as the translation constraint structure of the clamping rod group, which can not only position each elastic support cover but also push each group of elastic support covers outwards to open the elastic support cover for convenient material taking.

[0096] In this embodiment, the clamping rod group includes an upper clamping rod 53 and a lower clamping rod 54. The upper clamping rod 53 is spaced directly above the lower clamping rod 54, and both ends of the upper clamping rod 53 and the lower clamping rod 54 are slidably embedded in the chute 52. The elastic support cover 55 includes a bottom plate 551 and elastic clamping pieces 552. Elastic clamping pieces 552 extending upwards are provided at both ends of the bottom plate 551. The top ends of the elastic clamping pieces 552 are horizontally bent outwards to form extension plates 553. A clamping post 554 is provided at the outer end of the extension plate 553. The extension plate 553 passes through between the upper clamping rod 53 and the lower clamping rod 54 in a fitting manner, and the clamping post 554 is stopped on the outer sides of the upper clamping rod 53 and the lower clamping rod 54. The baffle 32 is placed on the outer side of the clamping post 554.

[0097] In S3.1 and S3.4, the included angle between the elastic clamping piece 552 and the bottom plate 551 is 70° - 85°.

[0098] In S3.2 and S3.3, the included angle between the elastic clamping piece 552 and the bottom plate 551 is 90°.

[0099] In the above scheme:

[0100] 1. The elastic support cover is designed as a deformable U-shaped structure. When opening the placement hole, the two groups of elastic clamping pieces can open outwards to facilitate opening the placement hole. When the placement hole needs to be closed, the elastic clamping pieces retract and reset, and the elastic clamping pieces can retract and press the substrate tightly.

[0101] 2. Extension plates are provided at both ends of the elastic clamping pieces. The upper clamping rod and the lower clamping rod can cooperate with the extension plates to slide. When opening and retracting, the upper clamping rod and the lower clamping rod constrain the translation of the extension plates.

[0102] 3. The clamping post can be used as the force application structure of the elastic clamping piece. At the same time, the clamping post can cooperate with the upper clamping rod and the lower clamping rod to stop, preventing the clamping post from moving excessively.

[0103] In this embodiment, the box body structure of the receiving box 6 is open at the top, and through grooves 61 are symmetrically opened on both sides of the receiving box 6. In S1, when the elastic support cover 55 is inserted into the receiving box 6, the extended plate 553 passes through the through grooves 61.

[0104] In the above solution, the outwardly extending plate can translate along the through slot to achieve the external force of the receiving box to adjust the internal elastic clip.

[0105] In this embodiment, a support assembly 4 is provided at the seed placement area 23, and the support assembly 4 includes a cover plate 41, a side plate 42, a matching plate 43, a driving rod 44 and a fixing plate 45. The surface of the cover plate 41 is provided with upper openings 311 arranged in a rectangular array, and the upper openings 311 are arranged opposite to the lower openings 411. A soil-opening assembly 7 is fixed inside the upper openings 311. Both sides of the cover plate 41 are vertically provided with side plates 42 extending downward, and the side plates 42 are relatively arranged on the outside of the bracket 31. A matching plate 43 is vertically provided in the middle of the side wall of the side plate 42, and a driving rod 44 is installed on the surface of the matching plate 43. The top end of the driving rod 44 is fixedly connected to the fixing plate 45, and the fixing plate 45 is fixed to the side of the ring conveyor belt 2.

[0106] In the above scheme, the driving rod can drive the cover plate to rise and fall, thereby completing the insertion and separation of the convex box. The operator looks down at the operation and completes the seed placement operation through the upper opening.

[0107] In the present embodiment, the earth-opening assembly 7 comprises a convex box 71, a soil-expelling plate 72, a telescopic rod 73 and a contact frame 74. The convex box 71 is fixed in the lower opening 411 and the top surface of the convex box 71 is flush with the top surface of the cover plate 41. The top of the convex box 71 is an open structure. A rectangular hole is opened at the center of the inner bottom surface of the convex box 71. The soil-expelling plate 72 is symmetrically arranged inside the rectangular hole. The bottom of the soil-expelling plate 72 extends downwardly outward from the convex box 71. A telescopic rod 73 is fixed on the top outer wall of the soil-expelling plate 72. The outer end of the telescopic rod 73 is vertically fixed to the inner wall of the convex box 71. A rectangular ring frame 711 is provided on the outer wall of the convex box 71. The outer wall of the convex box 71 is symmetrically provided with a contact frame 74. The contact frame 74 is relatively arranged on the inner side of the baffle plate 32, and the soil-expelling plate 72 is relatively arranged on the inner side of the contact frame 74. The side edge of the bottom surface of the convex box 71 is a chamfered structure.

[0108] In S3.2, specifically: when the driving rod 44 drives the cover plate 41 to move downward, the soil-opening assembly 7 is inserted into the receiving box 6 until the retaining ring contacts the top of the receiving box 6. At the same time, the contact frame 74 contacts the baffle plate 32 to move outward and stretch the bidirectional spring rod 33. The convex box 71 is inserted into the receiving box 6 and pushes the inclined elastic clip 552 outward to a vertical state. The combined soil-opening plate 72 is inserted into the seedling medium.

[0109] In S3.3, specifically: the hand of the seed placing personnel reaches into the convex box 71, and during this process, the hand touches the combined soil-pushing plate 72 and separates, and the separated soil-pushing plate 72 pushes out the placement hole 9 in the seedling substrate; the seed placing personnel releases the hand, so that the seed falls into the placement hole 9;

[0110] In S3.4, specifically: the convex box 71 is lifted up and separated from the accommodating box 6, the bidirectional spring rod 33 drives the baffle 32 to retract and reset, the baffle 32 pushes the clamping column 554 to move inward, so that the elastic clip 552 is reset from the vertical state to the inward tilt, and the two sets of elastic clips 552 synchronously clamp and close the placement hole 9.

[0111] In the above scheme:

[0112] 1. In S1, workers merge the groups of earthmoving plates in advance to facilitate the subsequent insertion of earthmoving plates;

[0113] 2. The soil-pushing plate is designed to be opened manually by the seed-planting personnel, and the soil-pushing plate can be opened to form a placement hole. In this way, the seeds can be accurately placed in the placement hole between the two sets of soil-pushing plates. Soil-pushing and seed-planting can be carried out continuously without waiting;

[0114] 3. When the convex box is inserted, the chamfered structure of the convex box can resist and stretch the elastic clip to realize the automatic opening of the elastic clip; at the same time, the resisting frame can push the baffle plate outward to ensure the normal outward movement of the card column, so that the elastic clip can expand outward normally. At the same time, the outer push of the baffle plate can also accumulate force. When the convex box is pulled out, the restoring force of the elastic clip itself and the restoring force of the baffle plate can synchronously extrude the matrix.

[0115] In this embodiment, the soil-moving plate 72 includes a vertical plate 721 and an inclined plate 722. The top of the vertical plate 721 is connected to the inclined plate 722. The bottom of the vertical plate 721 extends downwardly through a rectangular hole, and the bottom end of the vertical plate 721 is a conical structure. The telescopic rod 73 includes a support tube 731 and a movable rod 732. The movable rod is slidably embedded in the interior of the support tube. There is friction between the support tube and the movable rod. The outer end of the support tube is vertically fixed to the inner wall of the convex box 71, and the outer end of the movable rod is vertically fixed to the vertical plate 721. In S3.3, the hands of the seed-planting personnel touch the inclined plate 722, causing the two sets of vertical plates 721 to open.

[0116] In the above scheme:

[0117] 1. There is friction between the design support tube and the movable rod, and the movable rod can be in a specified extended position;

[0118] 2. The design of the inclined board can facilitate the seed placement personnel to push outward and realize the outward expansion of the vertical board; the tapered vertical board can facilitate the insertion of the substrate.

[0119] In this embodiment, the expanding component 8 includes a base 81. At both ends of the top surface of the base 81, expansion plates 82 are symmetrically provided. The expansion plate 82 includes a lower plate body 821. At the top of the lower plate body 821, right-angle plates 822 are symmetrically provided. The cross-section of the right-angle plate 822 is a right triangle, and the inclined surface of the right-angle plate 822 faces outward.

[0120] In S5.2, two groups of handle frames 51 are placed between two groups of expansion plates 82, and the inclined surface of the right-angle plate 822 is in sliding fit with the outer ends of the clamping rod groups. Press down the handle frames 51, and the right-angle plates 822 abut against the clamping rod groups and move them outward, driving the clamping posts 554 to move outward, so that the two groups of elastic clips open, facilitating the removal of the substrate-carrying pumpkin seedlings.

[0121] In the above solution:

[0122] When the worker presses the bearing component against the expansion plate, the right-angle plate can actively push the clamping rod group outward, causing the elastic clips to open actively, facilitating the worker to remove the pumpkin seedlings and the substrate.
