Description

Technical Field

[0001] The present invention relates to the technical field of seedling tray pressing devices, and particularly to a rapid pressing and forming device for rice straw seedling trays. Background Art

[0002] A seedling tray is a tool used for seedling raising in agriculture, especially widely used in the seedling raising processes of crops such as rice and vegetables. After crushing rice straw, it is cut and stirred in a stirring barrel, and then the crushed and stirred rice straw pulp is extruded into the seedling tray. After that, the seedling tray is pressed to drain the water and leave the crushed straw powder, forming a seedling tray that can be used for sowing.

[0003] However, during the process of crushing and stirring rice straw, when the proportion of rice straw powder in the mixed pulp is relatively large, the mixed pulp may be blocked at the discharge port and unable to be discharged. When the proportion of rice straw powder in the mixed pulp is relatively small, the dry matter entering the seedling tray is less, and the dry matter layer after extrusion and forming is too thin, which is not convenient for sowing seeds. Therefore, we introduce a rapid pressing and forming device for rice straw seedling trays. Summary of the Invention

The seedling tray is conveyed to the upper ends of the plurality of roller cylinders 17 through the seedling tray supply mechanism. A mixing box 39 is provided at the upper end of the through groove 2. The mixing box 39 is fixedly connected to the upper end of the base 1. A turntable 29 is provided inside the mixing box 39. The turntable 29 is fixedly connected to the output end of a second motor 4. The second motor 4 is fixedly connected to the lower end of the mixing box 39. A plurality of mixing cylinders 28 are fixedly connected to the upper end of the turntable 29. By turning on the second motor 4 to drive the turntable 29 to start rotating, the plurality of mixing cylinders 28 connected to the upper end thereof start to move through the rotation of the turntable 29. A stirring rod 33 is movably connected in the mixing cylinder 28. The upper end of the stirring rod 33 extends out of the mixing cylinder 28 and is fixedly connected to a gear 32. The gear 32 meshes with a tooth groove 37. The tooth groove 37 is opened inside the mixing cylinder 28 and inside the mixing box 39. During the rotation of the mixing cylinder 28, since the gear 32 meshes with the tooth groove 37, the stirring rod 33 starts to rotate during the movement of the mixing cylinder 28, so that the rice straw powder and water source are mixed together;

[0027] A discharging mechanism is provided below the mixing cylinder 28. The mixture in the mixing cylinder 28 is discharged by opening the discharging mechanism. By setting a time relay, the opening time of the discharging mechanism can be controlled, so that an equal amount of rice straw powder enters the mixing cylinder 28 each time. A fourth telescopic cylinder 22 is fixedly connected inside the mixing box 39. The output end of the fourth telescopic cylinder 22 is fixedly connected to a pulling plate 16. The pulling plate 16 is driven to move upward by the fourth telescopic cylinder 22, so that a discharging mechanism is opened. During the rotation of the turntable 29, a plurality of connecting wheels 30 are driven to start rotating, and at the same time, the pulling plate 16 moves back and forth between the plurality of connecting wheels 30, as Figure 5As shown, the upper end of the pull plate 16 is provided with a protrusion, and at the same time, a recess matching with the protrusion is provided inside the connecting wheel 30. Therefore, during the upward movement of the pull plate 16, the protrusion at the upper end of the pull plate 16 will be clamped into the recess inside the connecting wheel 30, so that the pull plate 16 can drive the connecting wheel 30 to move when moving upward. A crushing mechanism is provided at the upper end of the mixing tank 39 to crush the straw. Connecting mechanisms are provided on both sides of the mixing tank 39. The lower end of the crushing mechanism is fixedly connected with a telescopic pipe 11, and the lower end of the telescopic pipe 11 is connected to the connecting mechanism on the left side.

[0028] The circulating pump 25 is fixedly connected to the outside of the mixing tank 39. The input end of the circulating pump 25 extends into the water storage tank 5. The water storage tank 5 is arranged below the through groove 2 and is fixedly connected to the base 1. When the circulating pump 25 is started, the water source in the water storage tank 5 is pumped into the hose 24. The water source entering the hose 24 will enter the mixing cylinder 28 containing rice straw powder through the connecting mechanism on the right side. An extrusion mechanism is provided at the upper end of the base 1. When the seedling tray 8 containing the mixed pulp moves below the extrusion mechanism, the extrusion mechanism will extrude the mixed pulp in the seedling tray 8 at this time, so that the dry matter is stored in the seedling tray 8, while the water will be extruded out of the seedling tray 8 and fall into the water storage tank 5 for recycling. At this time, the seedling tray pressing and forming is completed. A connecting hole 38 is opened at the upper end of the mixing cylinder 28, and a blocking block 31 is movably connected in the connecting hole 38. The upper end of the blocking block 31 is arranged in a conical shape.

[0029] Embodiment 2:

[0030] On the basis of Embodiment 1, in order to enable the seedling tray 8 to be sent above a plurality of rollers 17 in sequence, the seedling tray supply mechanism includes a storage frame 21. A plurality of seedling trays 8 are stored in the storage frame 21. Openings for the seedling trays 8 to pass through are provided on both sides of the storage frame 21. A push plate 7 is provided on the right side of the storage frame 21. The push plate 7 is fixedly connected to the output end of the first telescopic cylinder 6. The first telescopic cylinder 6 is fixedly connected to the upper end of the base 1. The first telescopic cylinder 6 drives the push plate 7 to start moving. The push plate 7 enters the storage frame 21 from the opening on the right side of the storage frame 21 and pushes the seedling trays 8 in the storage frame 21, so that the seedling trays 8 are pushed below the mixing tank 39;

[0031] The discharging mechanism includes a discharging port 34 which is opened at the upper end of the turntable 29. A baffle 35 is slidably connected in the discharging port 34. One end of the baffle 35 is fixedly connected to a pulling rope 36. The end of the pulling rope 36 away from the baffle 35 extends into the upper end of the turntable 29 and is fixedly connected to the connecting wheel 30. A first spring 3 is sleeved outside the pulling rope 36. One end of the first spring 3 is fixedly connected to the baffle 35 and the other end is fixedly connected to the discharging port 34. When the pulling plate 16 moves upward to drive the connecting wheel 30 to move upward, at this time the pulling rope 36 is pulled, and the movement of the pulling rope 36 drives the baffle 35 to move, so that the first spring 3 is compressed. At this time, the mixed pulp in the mixing cylinder 28 will fall into the seedling tray 8 through the discharging port 34;

[0032] The shredding mechanism includes a shredding box 9 which is fixedly connected to the upper end of the stirring box 39. A cutting and shredding rod 13 is movably connected inside the shredding box 9. A first motor 10 is fixedly connected to the lower end of the shredding box 9. The output end of the first motor 10 is fixedly connected to the cutting and shredding rod 13. The upper end of the shredding box 9 is movably installed with a box cover 14 through a buckle. A through hole 27 is opened at the lower end of the shredding box 9. A sliding plate 26 is movably connected in the through hole 27. The sliding plate 26 is fixedly connected to the output end of the second telescopic cylinder 12. The second telescopic cylinder 12 is fixedly connected to the outside of the shredding box 9. The lower end of the through hole 27 is fixedly connected to the telescopic pipe 11. Open the box cover 14 and put the rice straw into the shredding box 9. After putting it in, reinstall the box cover 14 to the upper end of the shredding box 9 through the buckle. At this time, turn on the first motor 10 to drive the cutting and shredding rod 13 connected to its output end to start rotating. The cutting and shredding rod 13 crushes the rice straw through a plurality of cutting blades connected to its outside;

[0033] The connecting mechanism includes a connecting pipe 23 which is movably connected to the upper end of the stirring box 39. The connecting pipe 23 is fixedly connected to the output end of the connecting telescopic cylinder 15. The connecting telescopic cylinder 15 is fixedly connected to the outside of the stirring box 39. The squeezing mechanism includes a U-shaped plate 20 which is fixedly connected to the upper end of the base 1. An extrusion plate 18 is arranged inside the U-shaped plate 20. A third telescopic cylinder 19 is fixedly connected to the upper end of the U-shaped plate 20. The output end of the third telescopic cylinder 19 is fixedly connected to the extrusion plate 18.

[0034] Working principle: When in use, open the box cover 14 and put the rice straw into the shredding box 9. After putting it in, reinstall the box cover 14 to the upper end of the shredding box 9 through the buckle. At this time, turn on the first motor 10 to drive the cutting and shredding rod 13 connected to its output end to start rotating. The cutting and shredding rod 13 crushes the rice straw through a plurality of cutting blades connected to its outside. Turn on the connecting telescopic cylinder 15 to drive the connecting pipe 23 to move downward. When the connecting pipe 23 enters the connecting hole 38, at this time the stopper 31 in the connecting hole 38 will be squeezed to move, so that the mixing cylinder 28 is communicated with the connecting pipe 23;

[0035] After the rice straw is crushed, the second telescopic cylinder 12 is opened to drive the sliding plate 26 to start moving. The movement of the sliding plate 26 cancels the blockage of the through hole 27. At this time, under the rotation of the cutting and crushing rod 13, the crushed rice straw powder will enter the telescopic tube 11 through the through hole 27. The rice straw powder that enters the telescopic tube 11 will enter the connecting tube 23 and finally enter the mixing cylinder 28 through the connecting hole 38. After the addition is completed, the second telescopic cylinder 12 is used to control the sliding plate 26 to block the connecting hole 38 again. At the same time, the connecting telescopic cylinder 15 will control the connecting tube 23 to disengage from the connecting hole 38. At this time, the stopper 31 will block the connecting hole 38 again;

[0036] The second motor 4 drives the turntable 29 to start rotating. The rotation of the turntable 29 drives a plurality of mixing cylinders 28 arranged at its upper end to start moving. When the mixing cylinder 28 storing the rice straw powder moves to the lower side of the connecting tube 23 on the right, the connecting telescopic cylinder 15 on the right will be activated, so that the connecting tube 23 on the right enters the corresponding connecting hole 38. The circulating pump 25 is started to pump the water source in the water storage tank 5 into the hose 24. The water source that enters the hose 24 will enter the mixing cylinder 28 storing the rice straw powder. At this time, the connecting telescopic cylinder 15 will drive the connecting tube 23 to disengage from the connecting hole 38 again. At the same time, the second motor 4 will be started to drive the turntable 29 to start rotating, so that a plurality of mixing cylinders 28 start to rotate;

[0037] During the rotation of the mixing cylinder 28, since the gear 32 is engaged in the tooth groove 37, during the movement of the mixing cylinder 28, the stirring rod 33 will start to rotate, so that the rice straw powder and the water source are mixed together. After the mixing is completed, the first telescopic cylinder 6 drives the push plate 7 to start moving. The push plate 7 moves to push the seedling tray 8 in the storage frame 21, so that the seedling tray 8 is pushed below the mixing box 39. After the pushing is completed, the first telescopic cylinder 6 drives the push plate 7 back to its original position. The seedling tray 8 in the storage frame 21 will fall downward. At this time, the second motor 4 is turned off to stop the rotation of the turntable 29. By opening the fourth telescopic cylinder 22 to drive the pull plate 16 to start moving, the pull plate 16 moves upward to drive the connecting wheel 30 to move upward. At this time, the pull rope 36 is pulled, and the movement of the pull rope 36 drives the baffle 35 to move, so that the first spring 3 is compressed. At this time, the mixed slurry in the mixing cylinder 28 will fall into the seedling tray 8 through the discharge port 34;

[0038] The fourth telescopic cylinder 22 drives the pull plate 16 to move downward. At this time, under the elastic force of the first spring 3, the baffle 35 blocks the discharge port 34 again. At this time, rice straw powder and water can be added to the empty mixing cylinder 28 again. When the new seedling tray 8 is pushed to the lower side of the mixing box 39, the seedling tray 8 containing the mixed pulp will be pushed to start moving. When the seedling tray 8 containing the mixed pulp moves to the lower side of the pressing plate 18, the third telescopic cylinder 19 will drive the pressing plate 18 to move downward. The pressing plate 18 moves to press the mixed pulp in the seedling tray 8, so that the dry matter is stored in the seedling tray 8, while the water is squeezed out of the seedling tray 8 and falls into the water storage tank 5 for recycling. When the third telescopic cylinder 19 drives the pressing plate 18 back to its original position, the forming of the seedling tray is completed.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
