Description

Vegetable matrix block seedling whole plate shedding device

technical field

The invention relates to a whole plate shedding device for vegetable matrix seedlings, which belongs to the technical field of agricultural machinery.

Background technique

Vegetable planting methods are mainly live broadcasting and transplanting. Live broadcasting is to directly sow vegetable seeds in the soil to let them grow and germinate in a natural state. It has high requirements on the weather, temperature and water in the field. Northeast and Northwest regions of my country, etc. On the other hand, vegetable seedlings are vulnerable to severe weather such as early frost, which seriously affects the yield of vegetables. Transplanting is to first cultivate the seeds into seedlings in an environment of suitable temperature and water nutrition, and then transplant them into the soil when the seedlings grow to a certain state. The comprehensive benefits of the cycle can make full use of light and heat energy, advance the growth period of crops by 15 days, eliminate the impact of bad weather on crops, improve the survival rate of seedlings, and prolong the growth period of crops, effectively increasing the yield and quality of vegetables. Quality, with significant cost-saving, production-increasing, and income-increasing effects. Its economic and social benefits are very considerable, and about 60% of the vegetables are planted by seedlings and transplanted.

At present, vegetable transplanting seedlings mainly include plug seedlings, bare seedlings and matrix block seedlings. Due to the regular block and good standing stability of the substrate block seedlings, it can effectively inhibit lodging after planting, and there is no barrier between the seedling blocks, which can realize the whole row of seedlings and improve the efficiency of seedling picking. The quality requirements for seedlings during mechanical transplanting Low, seedling age and plant shape do not affect the effect of seedling separation, so matrix block seedlings are an effective way to ensure vegetable planting quality, improve transplanting efficiency, and achieve high-speed transplanting.

According to the applicant's understanding, the objects of taking and dividing seedlings of the existing automatic transplanting machine are mostly aimed at the plug seedlings, but the shape and structure of the plug seedlings and the matrix block seedlings are different, so it cannot be applied to the seedling trays of the matrix block seedlings to take and divide the seedlings. At present, the transplanting operation of vegetable matrix seedlings is mainly based on artificial seedling separation, but manual seedling separation has defects such as high labor intensity and low operation efficiency, and it is difficult to realize large-scale vegetable transplanting, which seriously restricts the use of transplanting machines. development and application.

After retrieval, the Chinese patent with the publication number CN113303056A (the publication date is August 27, 2021) discloses an automatic seedling-picking and sending device for vegetable transplanting machines. The seedlings are thrown by transmission, so that the seedlings of the vegetable matrix can be taken in rows. However, in this patent, only a single row of substrate block seedlings can be taken each time the seedlings are taken, and the operation efficiency is still low, and the low efficiency of seedling retrieval has also become one of the key factors restricting the whole process of automatic transplanting of vegetable substrate block seedlings.

Described combination seedling tray 11, as shown in Figure 1-Fig. Both the plate 12 and the first side plate 14 are arranged vertically, and the pumping plate 13 is arranged horizontally and above the first combined plate 11 .

As shown in Figure 1, the first combined plate 11 and the first side plate 14 respectively have two pieces, which are combined with the pumping plate 13 to form a square box shape with an open top; the second combined plate 12 and the first side plate 14 are arranged in parallel, and its two ends are fixedly connected with two first composite plates 11 respectively; the second composite plate 12 has multiple pieces, three pieces in FIG. Preferably, the first side plate 14 is provided with a keyway 18 , both ends of the first combination plate 11 are inserted into the keyway 18 , and the first combination plate 11 can slide up and down along the keyway 18 .

The pumping plate 13 is provided with a number of bar-shaped grooves 17 corresponding to the second combination plate 12 and the first side plate 14 one by one, and the second combination plate 12 and the first side plate 14 are inserted into the corresponding bar-shaped grooves 17 , the strip-shaped groove 17 is provided with an opening near the end of the same first combination plate 11 .

As shown in Figures 1-3, the first side plate 14 is provided with a through hole 15 extending along the length direction, and the pumping plate 13 is provided with a support rod 16 inserted into the through hole 15. In this embodiment, the support The rod 16 is adjacent to the outermost bar-shaped groove 17, and the through hole 15 and the support rod 16 form a moving pair. The shape of the through hole 15 is not limited, and may be a circular through hole, a rectangular through hole or an elliptical through hole, etc. In this embodiment, a rectangular through hole is used.

As shown in Figures 1 and 2, the seedling sending device 2 includes a conveyor belt 22 arranged horizontally and two second side plates 21 arranged above the conveyor belt 22 and a plurality of vertical plates parallel to the second side plates 21 23, the conveyor 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 frame, and the vertical plates 23 correspond to the second combined plates 12 one by one , the bottom of the second combined board 12 is provided with a first slit opening downward, and the vertical board 23 is inserted into the first slit of the corresponding second combined board 12; The side plates 14 correspond one to one, and the bottom 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 corresponding to the first side plate 14 .

In this embodiment, the first combined plate 11, the second combined plate 12, the pumping plate 13 and the first side plate 14 constitute the combined seedling tray 1, and a number of conveying trays are formed between the second combined plate 12 and the first side plate 14. As for the track, a one-to-one corresponding conveying track is also formed between the second side plate 21 and the vertical plate 23 . As shown in Figure 4, the matrix block seedlings 3 are arranged in rows along the conveying track. After the seedling cultivation on the combined seedling tray 1 is completed, the combined seedling tray 1 is placed on the seedling delivery device 2, that is, the first side plate 14 The second slit 19 is embedded along the second side plate 21, and the first slit of the second combination plate 12 is embedded along the vertical plate 23, so that the rows of substrate block seedlings 3 in the combined seedling tray 1 and the conveying device each row Conveyor track one-to-one correspondence; At this moment, draw out the bottom pumping plate 13 of combined seedling tray 1 along the through hole 2015 track on the combined seedling tray 1, matrix piece seedling 3 falls into the conveying track correspondingly, and is separated into different parts by vertical plate 23. The matrix seedlings 3 arranged in rows finally fall onto the conveyor belt 22 to realize the forward transport of the matrix seedlings 3, and the next step of seedling separation is carried out by the subsequent seedling separation device.

But because the substrates of different components and the root systems of different crops are not well developed, when the bottom pumping plate 13 is pulled out again, some substrate block seedlings 3 cannot fall well. In order to solve the above problem, preferably, the depth of the first slit of the second combined board 12 is no more than half of the height of the second combined board 12 .
