Background

At present, tobacco seedling in China basically adopts a floating seedling method of greenhouse management: after compounding and uniformly stirring the matrix, putting the matrix into a seedling tray, then sowing the coated tobacco seeds into seedling holes of the seedling tray, and then putting the seedling tray into a seedling pool for cultivation. The existing seedling raising tray has realized standard specification production, is mostly made of foam plastics, and the bottom wall of a seedling hole is provided with a hole so that nutrient solution in a seedling pool can enter a substrate in the seedling hole and be supplied to tobacco seeds for absorption and growth. The tobacco seedling culture substrate in the prior art comprises three components, namely grass peat, vermiculite and expanded perlite, and the optimal proportion of the grass peat, the vermiculite and the expanded perlite is about 6: 2: 2, the grass peat is used for providing main nutrient components for the development of tobacco seeds, and water is added in advance to ensure that the water content of the grass peat reaches 60 percent so as to meet the requirement of the initial development of the tobacco seeds; the vermiculite can absorb water by virtue of the capillary action of the vermiculite, so that the substrate is kept to be continuously wet, and the expanded perlite realizes the ventilation of the substrate by virtue of the porous structure of the expanded perlite so as to prevent the roots of the tobacco seedlings from being anoxic.

Among the prior art, the staff is comparatively rough to the mixed operation of three kinds of components, adopts instrument manual stirring such as shovel more, perhaps adopts equipment such as mixer to stir, and these two kinds of modes all have certain drawback: when the vermiculite or the expanded perlite is used as a tobacco seedling breeding substrate component, the particle size is small, and the vermiculite or the expanded perlite has a good water absorption effect, so that when the vermiculite or the expanded perlite is mixed with a moist substrate, water can be absorbed quickly and easily to generate agglomeration and aggregation, the vermiculite or the expanded perlite cannot be uniformly mixed with turf, the substrate component in each seedling hole in a seedling tray cannot be guaranteed to be reasonable, the substrate in some seedling holes is completely turf, the substrate absorbs water and is supersaturated, the root system of the tobacco seedling is anoxic, and the activity is reduced; some seedling holes have too high content of vermiculite or/and expanded perlite, which affects the cracking of the coated seeds and the absorption of moisture and nutrition by the seedlings, and further causes low seedling rate of the tobacco seeds.

The invention realizes the uniform mixing of the matrix components in each seedling hole of the seedling tray by the following means: firstly, designing the size of a matrix box according to a seedling raising tray to ensure that the matrix box and the seedling raising tray have the same length, width and outer wall thickness, wherein the height of the matrix box is 60% of the depth of seedling holes, and when the matrix box is filled with turf and the turf is filled into the seedling holes at the later stage, 60% of turf is filled into each seedling hole; the feeding shovel is filled with a mixture of vermiculite and expanded perlite, the mixture is laid uniformly in thickness, the feeding shovel is used for jacking the upper box body and enabling the mixture to enter a space between the upper box body and the lower box body, the upper and lower discharging plates are opened, the mixture of the vermiculite and the expanded perlite can be laid on grass carbon of the lower box body uniformly in thickness, and a square frame on the crimping device is used for distributing the same amount of grass carbon-vermiculite and expanded perlite mixture-grass carbon groups to each seedling hole of the seedling raising plate, so that the substrates in each seedling hole are guaranteed to have components and proportions close to the same amount. The respective dosage of the vermiculite and the expanded perlite can be determined as 1/3 of the turf, the size of the substrate box can be determined on the premise of adopting a standard-size seedling tray as the substrate box is manufactured according to the size of the seedling tray, the size of the substrate box can be determined, the frame size of the feeding shovel and the dosage of the turf, the vermiculite and the expanded perlite can be further determined, and after the dosage of the vermiculite and the expanded perlite is determined, the vermiculite and the expanded perlite are mixed in a dry state, so that the phenomenon of water absorption and agglomeration cannot be caused, and the rapid and uniform laying operation can be realized. The substrate entering the seedling hole is stirred under the action of the stirring rod, and the three components can be mixed.

The specific process is as follows:

firstly, sealing the bottom of a lower box body by gauze, then buckling, pressing and butting an upper box body and a lower box body to form a complete matrix box, at the moment, enabling a limiting clamping strip to be in a vertical state, and then quantitatively and uniformly loading turf into the matrix box and fully paving the matrix box; simultaneously the reinforced shovel of this moment is kept away from matrix box and the effect that the flitch received limit baffle presents the shutoff and adds the shovel bottom state, goes up the flitch and moves to the tip that corresponds the slide so that it is uncovered to add the shovel top, evenly lays quantitative vermiculite and expanded perlite mixture in adding the shovel, and the height that highly is greater than the second drive block of first drive block this moment moreover.

After vermiculite and expanded perlite mixture and turf are filled respectively, the output end of the electric cylinder is driven to extend and indirectly enable the feeding plate to move along the corresponding slide way, after the top of the feeding plate blocking and feeding shovel is opened, the feeding plate reaches the stroke end of the slide way and pushes the feeding shovel to move, meanwhile, the shifting block of the feeding plate passes through the second driving block and abuts against the first driving block, so that the lower plate is kept closed to the bottom of the feeding shovel, therefore, the feeding shovel is inserted into the butt joint of the upper box body and the lower box body from the opening of the matrix box and enters the space between the upper box body and the lower box body, and meanwhile, the protruding wedge block of the feeding shovel causes the protruding of the blocking belt, so that the frame body of the feeding shovel is in butt joint with the upper box body. And at this moment, the frame body is blocked by the blocking belt and can not advance, but the driving electric cylinder still keeps extending for a certain displacement, so that the transmission rod can only overcome the friction force between the transmission rod and the silica gel ring in the sleeve to advance the displacement, meanwhile, the connecting plate drives the rack to also advance the displacement (the displacement is carried out at the distance between the rack and the transmission plate), but the blanking plate has no displacement relative to the frame body, so that the movement of the rack can cause the turnover of the transmission gear, and further the turnover of the driving turbine is driven by the shaft rod, the driving turbine enables the worm to rotate and drives the connecting rod to turnover, and further the first driving block and the second driving block are driven to rotate, so that the height positions of the first driving block and the second driving block are interchanged, namely the first driving block rotates downwards, the second driving block rotates upwards, and further.

Meanwhile, the charging shovel divides the turf in the matrix box into two parts, namely a part positioned in the upper box body and the top of the upper material plate and a part remained in the lower box body, and simultaneously the charging shovel causes the upper box body to be lifted in the inserting process, so that the top surface of the turf in the upper box body can relatively descend (the turf is still in the wrapping range of the upper box body and the lower box body and cannot leak due to the existence of the inner side plate and the elastic plugging belt on the lower box body) The limiting block connecting rod of the lower box body is in sliding fit, and the length of the long hole in the limiting clamping strip can limit the maximum vertical distance between the upper box body and the lower box body.

Then the driving electric cylinder controls the output end to retract for a certain displacement and drives the upper material plate to move outwards along the corresponding slide way, and simultaneously, as the shifting block is contacted with the second driving block, the poking block on the upper material plate can push against the second driving block to drive the lower material plate to move outwards together, so that the frame body of the feeding shovel is opened up and down, the vermiculite and the expanded perlite in the feeding shovel can be uniformly paved on the top surface of the turf in the lower box body in equal thickness, the matrix box is in a laminated and laminated state from top to bottom of about 50 percent of turf-vermiculite and expanded perlite mixture, and simultaneously the height of the whole matrix in the matrix box is close to the depth of a seedling hole of a seedling tray, because the lower box body is provided with the inner side plate and the elastic plugging belt, the matrix is still positioned in the wrapping range of the upper box body and the lower box body and can not cause the leakage phenomenon.

Then the output of control cylinder pushes down the base plate, make base plate and connecting plate and stirring actuating mechanism move down, cut into the matrix in the matrix box along with the square frame, to educate seedling tray and place box body and corresponding gauze under down, make the square frame cut the gauze of below simultaneously, and enter into the seedling cave of educating seedling tray thereupon, gauze pastes seedling cave bottom wall setting this moment, the matrix is located the parcel within range of gauze and square frame, make the square frame enter into the seedling cave of educating seedling tray thereupon, the matrix is in the parcel within range of seedling cave bottom wall and square frame this moment, the coniform structure of whole process puddler bottom keeps the shutoff to square frame top through-hole simultaneously. Then controlling the output end of the stirring electric cylinder to extend and retract, further enabling the connecting plate to drive the stirring rod to repeatedly move up and down in the square frame, wherein the bottom of the stirring rod is conical, so that the up-and-down movement of the stirring rod can well drive the substrate between the square frame and the bottom wall of the seedling hole to move up and down, and the height of the square frame is greater than the depth of the seedling hole, so that the space of the square frame is enough to enable the up-and-down movement of the substrate to be converted into vertical and horizontal mixing actions, thereby realizing the uniform mixing of the turf, vermiculite and expanded perlite, meanwhile, when the conical sharp end point of the stirring rod contacts gauze, the gauze corresponding to the hole of the bottom wall of the seedling hole can be punctured, because the root systems of certain tobacco seedlings are vigorous and can possibly extend outwards from the hole, the existence of the gauze can not form a barrier, so that the gauze needs to puncture a hole, the root system is provided with an extending path, of course, the holes on the seedling holes are smaller, and the stirring rod only utilizes the conical sharp end point to puncture the gauze, so that the substrate is not leaked from the corresponding holes.

Then in the up-and-down movement process of the connecting plate, the output end of the control cylinder retracts and resets, so that the square frame is separated from the seedling raising plate, and the corresponding matrix is left in each seedling hole of the seedling raising plate under the action of gravity. Because the square frame is vertical motion when cutting into the matrix box, so can guarantee effectively that the matrix in the square frame still is the state of the layering and laminating from top to bottom of grass peat-vermiculite and expanded perlite mixture-grass peat, vermiculite and expanded perlite are in the dry state when evenly spreading on the grass peat in box body down and laying in addition, can not produce the reunion effect, so the matrix component proportion in every square frame can comparatively accord with the grass peat: vermiculite and expanded perlite is 6: 2: 2, the optimal proportioning requirement.

Then the output end of the driving electric cylinder is controlled to retract and reset, and the frame body and the blanking plate are driven to move out of the matrix box through the feeding plate, and the upper blanking plate, the blanking plate and the frame body do not have relative displacement in the process, until the blanking plate contacts the limit baffle, the blanking plate can not move, and the shifting block and the feeding plate can not move under the limitation of the second driving block, but the output end of the driving electric cylinder still retracts, so that the transmission rod can retract and reset the displacement only by overcoming the friction force between the transmission rod and a silica gel ring in the sleeve, namely the transmission rod resets relative to the sleeve, and simultaneously the connecting plate drives the rack to retract and reset the displacement (the displacement is also carried out at the interval between the rack and the transmission plate), but the blanking plate does not have displacement, so that the movement of the rack can cause the reverse turnover of the transmission gear, and then the worm is driven, and then drive first, second drive block antiport, make first, the interchange of second drive block height position, first drive block upwards rotates promptly, the second drive block rotates downwards, and then make the stirring piece can cross the second drive block, go up the flitch at this moment and no longer receive the restriction of flitch down, and then the relative sleeve of transfer line does not have the displacement and continues to move under the drive of driving electric jar, make it drive the framework and continue to move until the framework moves to the formation terminal point of flitch and corresponding slide down, make the flitch seal framework bottom, and go up the flitch and continue to keep the uncovered state at framework top, the operation that resets completely is wholly realized.

Go up the flitch and down the design of flitch go up the fixture block, mainly utilize the cooperation of fixture block and spacing spout, guarantee that upper and lower flitch can't shift out the slide on the loading shovel framework completely for go up the flitch and can drive the loading shovel framework and reset and remove.

Finally, the plurality of square frames are arranged according to the seedling holes of the seedling raising plate, gaps exist among the square frames due to the separation walls among the seedling holes, simultaneously, matrix distributed in a grid shape is remained in the matrix box after the square frames are pressed down, and the remained matrix is mixed and collected to be used as nutrition pot matrix of other crops, such as flowers, fruit trees and the like, which do not need to float for raising seedlings. Similarly, the corresponding gauze can remain in the grid-shaped area, and the next operation can be performed only by controlling the gauze motor to drive the driving roller to rotate, winding the grid-shaped part on the driving roller and moving the brand-new gauze to the position right below the lower box body. Certainly, in order to facilitate the cutting of gauze, a metal grid mesh with the same structure as the top surface of the seedling raising tray can be prefabricated, and the metal grid mesh is placed above the seedling raising tray, so that gauze can be cut off by abutting against the side of the metal grid when the square frame is cut down.

Compared with the prior art, the invention has the following advantages: the invention has simple structure, can effectively mix grass carbon, vermiculite and perlite and uniformly fill the grass carbon, vermiculite and perlite into seedling holes of the seedling tray, so that the matrix components in each seedling hole have reasonable proportion, and the survival rate and activity of tobacco seedlings are improved.
