Description

TECHNICAL FIELD

[0001] The present application relates to a vegetable substrate block seedling whole tray falling device, belonging to the technical field of agricultural machinery. BACKGROUND

[0002] Vegetable planting methods mainly include direct seeding and transplanting. Direct seeding is to directly sow vegetable seeds in the soil and let them grow in a natural state, which has high requirements for weather, temperature and moisture in the field. In northeast and northwest China, for example, vegetable seedlings are easily affected by early frost and other severe weather, which seriously affects the yield of vegetables. Transplanting is to first cultivate seeds into seedlings in a suitable temperature and moisture environment, and then transplant the seedlings into the soil when they grow to a certain state. Compared with direct seeding, transplanting has the comprehensive benefits of resisting severe weather and extending the growth period, can fully utilize light and heat energy, advance the growth period of crops by 15 days, eliminate the impact of adverse weather on crops, improve the survival rate of seedlings, extend the growth period of crops, and effectively improve the yield and quality of vegetables, with significant cost reduction, yield increase and income increase effects. Its economic and social benefits are very considerable, and about 60% of vegetables are planted through seedling transplanting mode.

[0003] At present, there are several types of vegetable transplanting seedlings, including plug seedlings, bare seedlings and substrate block seedlings. Substrate block seedlings have regular block shape, good standing stability, can effectively inhibit post-transplanting lodging, and have no barriers between seedling blocks, which can realize whole-row seedling taking and improve seedling taking efficiency. The quality requirement of mechanical transplanting for seedling is low, and the size and plant morphology of seedling age do not affect the seedling taking effect, so substrate block seedling is an effective seedling method to ensure the quality of vegetable transplanting, improve the efficiency of transplanting and realize high-speed transplanting.

[0004] According to the applicant's understanding, the existing automatic transplanting machine mainly takes plug seedlings as the object, but the shape and structure of plug seedlings and substrate block seedlings are different, which cannot be applied to substrate block seedling trays for seedling taking. At present, the transplanting operation of vegetable substrate block seedlings mainly relies on manual seedling taking, which has the defects of high labor intensity and low operation efficiency, and it is difficult to realize large-scale vegetable transplanting, which seriously restricts the development and application of transplanting machines.

[0005] Through retrieval, a vegetable transplanting machine automatic seedling taking and sending device is disclosed in Chinese patent No. CN113303056A (publication date: August 27, 2021), which uses a cylinder to take seedlings, cooperates with chain transmission to send seedlings, and uses belt transmission to plant seedlings, so as to realize the taking of vegetable substrate block seedlings by rows. However, in this patent, only single-row substrate block seedlings can be taken each time, and the operation efficiency is still low. Low seedling taking efficiency is one of the key factors restricting the full-automatic transplanting of vegetable substrate block seedlings. SUMMARY

[0006] The technical problem solved by the present application is to provide a vegetable matrix block seedling whole tray falling device capable of reducing labor intensity and improving transplanting operation efficiency.

[0007] To solve the above technical problems, the technical scheme of the present application is as follows: a vegetable matrix block seedling whole tray falling device, comprising a combined seedling tray and a seedling feeding device.

[0008] The combined seedling tray comprises a first combined plate, a second combined plate, a pulling plate and a first side plate, the first combined plate, the second combined plate and the first side plate are vertically arranged, and the pulling plate is horizontally arranged above the first combined plate.

[0009] The first combined plate and the first side plate each have two plates, which are combined with the pulling plate to form a square box-shaped top opening; the second combined plate is arranged in parallel with the first side plate, and its two ends are fixedly connected with the two first combined plates; the second combined plate has multiple plates, which are uniformly distributed between the two first side plates.

[0010] The pulling plate is provided with a plurality of strip-shaped grooves corresponding to the second combined plate and the first side plate, the second combined plate and the first side plate are inserted into the corresponding strip-shaped grooves, and the strip-shaped grooves are provided with openings at the end close to the same first combined plate.

[0011] The first side plate is provided with a through hole extending in the length direction, the pulling plate is provided with a support rod inserted into the through hole, and the through hole and the support rod constitute a moving pair.

[0012] The seedling feeding device comprises a horizontally arranged conveying belt, two second side plates arranged above the conveying belt and a plurality of vertical plates parallel to the second side plates, the conveying belt is located between the two second side plates; the second side plates and the vertical plates are fixed on a rack, the vertical plates correspond to the second combined plates one by one, the lower part of the second combined plate is provided with a first slit opening downward, and the vertical plate is inserted into the first slit of the corresponding second combined plate; the second side plates correspond to the first side plates one by one, the lower part of the first side plate is provided with a second slit opening downward, and the second side plate is inserted into the second slit of the corresponding first side plate.

[0013] The working principle of the present application is as follows: the first combination plate, the second combination plate, the pull-out plate and the first side plate constitute a combined seedling tray, a plurality of conveying tracks are formed between the second combination plate and the first side plate, and a one-to-one corresponding conveying track is also formed between the second side plate and the vertical plate. The matrix block seedlings are arranged in rows along the conveying tracks, and after the seedling raising on the combined seedling tray is completed, the combined seedling tray is placed above the seedling feeding device, that is, the second slit of the first side plate is embedded along the second side plate, and the first slit of the second combination plate is embedded along the vertical plate, so that the row of matrix block seedlings in the combined seedling tray correspond to each row of conveying tracks of the conveying device one by one; at this time, the bottom pull-out plate of the combined seedling tray is pulled out along the hole track on the combined seedling tray, the matrix block seedlings fall into the conveying tracks correspondingly, and are isolated into different rows by the vertical plate, and finally fall into the conveying belt, realizing the forward conveying of the whole tray of matrix block seedlings, and the next step of seedling separation work is carried out by the subsequent seedling separation device.

Preferably, the first side plate 14 is provided with a key groove 18, and the two ends of the first combination plate 11 are inserted into the key groove 18, and the first combination plate 11 can slide up and down along the key groove 18.

[0024] The pull-out plate 13 is provided with a plurality of strip-shaped grooves 17 corresponding to the second combination plate 12 and the first side plate 14, the second combination plate 12 and the first side plate 14 are inserted into the corresponding strip-shaped grooves 17, and the strip-shaped grooves 17 are provided with openings at the end close to the same first combination plate 11.

[0025] As shown in the drawings, Figures 1-3 the first side plate 14 is provided with a through hole 15 extending in the length direction, and the pull-out plate 13 is provided with a support rod 16 inserted into the through hole 15, and in this embodiment, the support rod 16 is adjacent to the outermost strip-shaped groove 17, and the through hole 15 and the support rod 16 constitute a moving pair. The shape of the through hole 15 is not limited, which can be a circular through hole, a rectangular through hole or an oval through hole, etc., and in this embodiment, a rectangular through hole is adopted.

[0026] As shown in the drawings, Figure 1 and Figure 2 the seedling feeding device 2 comprises a conveying belt 22 arranged horizontally and two second side plates 21 and multiple vertical plates 23 arranged above the conveying belt 22 and parallel to the second side plates 21, the conveying belt 22 is located between the two second side plates 21; the second side plates 21 and the vertical plates 23 are fixed on the rack, the vertical plates 23 correspond to the second combination plates 12 one by one, the lower part of the second combination plate 12 is provided with a first slit opening downward, and the vertical plate 23 is inserted into the first slit of the corresponding second combination plate 12; the second side plate 21 corresponds to the first side plate 14 one by one, and the lower part of the first side plate 14 is provided with a second slit 19 opening downward, and the second side plate 21 is inserted into the second slit 19 of the corresponding first side plate 14.

[0027] In this embodiment, the first combined plate 11, the second combined plate 12, the drawer plate 13, and the first side plate 14 constitute a combined seedling tray 1. A plurality of conveying tracks are formed between the second combined plate 12 and the first side plate 14, and corresponding conveying tracks are also formed between the second side plate 21 and the vertical plate 23. Figure 4 As shown, the substrate block seedlings 3 are arranged in rows along the conveying track. After the seedlings are cultivated on the combined seedling tray 1, the combined seedling tray 1 is placed on the seedling delivery device 2. That is, the second seam 19 of the first side plate 14 is embedded along the second side plate 21, and the first seam of the second combined plate 12 is embedded along the vertical plate 23, so that the rows of substrate block seedlings 3 in the combined seedling tray 1 correspond one-to-one with the rows of conveying tracks of the conveying device. At this time, the bottom plate 13 of the combined seedling tray 1 is pulled out along the through hole 2015 on the combined seedling tray 1, and the substrate block seedlings 3 fall into the corresponding conveying track. They are separated into different rows of substrate block seedlings 3 by the vertical plate 23 and finally fall onto the conveyor belt 22, realizing the forward conveying of the entire tray of substrate block seedlings 3, and the subsequent seedling separation device performs the next seedling separation work.

[0028] However, due to the varying root development levels of different substrates and crops, some substrate block seedlings 3 may not fall properly when the bottom plate 13 is removed. To address this issue, preferably, the depth of the first seam in the second combined plate 12 does not exceed half the height of the second combined plate 12. However, to ensure the stability of the combined seedling tray 1 when embedded in the vertical plate 23, preferably, the depth of the first seam in the second combined plate 12 is greater than one-fifth of the height of the second combined plate 12.

[0029] In this embodiment, the depth of the first slit is preferably one-third of the height of the second combined plate 12. This ensures that when the bottom plate 13 is pulled out, the vertical plate 23 on the conveyor and the vertical plate 23 inside the combined seedling tray 1 are also embedded together. Since the depth of the first slit in the combined seedling tray 1 is only one-third of the height of the entire second combined plate 12, during the embedding process, the entire I-shaped frame composed of the first combined plate 11 and the second combined plate 12 is lifted upwards by the vertical plate 23 in the seedling delivery device 2 and moves relative to each other along the keyway 18 trajectory on the two first side plates 14 of the combined seedling tray 1, thereby ensuring that the entire tray of substrate block seedlings 3 falls onto the conveyor track. The conveyor belt 22 is driven by a stepper motor to transport the substrate block seedlings 3 forward, completing the subsequent individual separation of the substrate block seedlings 3. This embodiment enables the detachment of the entire tray of substrate block seedlings, significantly improving seedling retrieval efficiency.
