Description

Technical Field

[0001] The present invention relates to the technical field of red sand cultivation, and in particular to a device and method for cultivating red sand indoors. Background Art

[0002] Red sand is a plant of the genus Red sand of the Tamarix family. It is the founding and dominant species of temperate desert grasslands. The average plant height is 30 cm. It has strong resistance to wind and sand and drought. It is an important super-xerotolerant shrub in the arid desert areas of northwest my country and has important ecological value.

[0003] Indoor cultivation provides the possibility for factory-based seedling cultivation. The cultivation technology is used to produce plug-tray seedlings for suitable afforestation. It is not restricted by seasons and can grow into seedlings in one go under natural conditions. In the cultivation process, the first step is to obtain sterile materials, take mature seeds, rub off the surface villi by hand, soak the seeds in tap water for 30 minutes, and rinse them for 20 minutes. Depilation removes various pathogens on the seed villi, which is beneficial for preventing seedling diseases. After depilation, the mutual adhesion between seeds is reduced, and the seed maturity is clearly visible from the surface, which is convenient for mechanical and manual selection. However, the efficiency of manually rubbing off the surface villi is low, and there are a small number of red sand seeds with incomplete removal of the villi. Summary of the invention

[0014] Preferably, a plurality of first guide blocks and second guide blocks are arranged between the two sponges, and the first guide blocks and the second guide blocks are arranged alternately in sequence above the blocking block. The first guide block is composed of two puzzle blocks, which have an upward tip when the two puzzle blocks are put together, which is consistent with the tip of the blocking block. The second guide block is composed of two puzzle blocks, which have a virtual tip along its edge line when the two puzzle blocks are separated, which is opposite to the tip of the blocking block. Through the plurality of first support blocks, the plurality of first guide blocks are arranged at a fixed position between the two sponges, and through the plurality of second support blocks, the plurality of second guide blocks are arranged at a fixed position between the two sponges.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Reference Figure 1 -Attached Fig. 9 , a red sand seed fluff stripping component, comprising:

[0036] Sponge bodies 1, two in number and symmetrically arranged, contacting and fitting each other;

[0037] The blocking block 2 is located between the two sponge bodies 1, and the width of the blocking block 2 is smaller than the width of the red sand seed and larger than 1 / 2 of the width of the red sand seed;

[0038] Among them, the contact part between the sponge 1 and the blocking block 2 is compressed and deformed toward the sponge 1, and the red sand seed is placed between the two sponges 1 and above the blocking block 2. A force is applied to make the two sponge blocks that fit each other move downward. The red sand seed is blocked by the blocking block 2 and cannot move. Sliding friction occurs between the sponge blocks that can continue to move, causing the fluff to fall off the red sand seed.

[0039] The peeling assembly also includes four driving rollers 3, two of which form a group. The two driving rollers 3 in the same group are connected by a conveyor belt 4. The sponge 1 is annular and sleeved on the conveyor belt 4. The inner wall of the sponge 1 and the conveyor belt 4 are bonded. The two groups of driving shafts rotate synchronously and in opposite directions, so that the sponge 1 follows the conveyor belt 4 and runs at a uniform speed.

[0040] The stripping assembly also includes a pool body 5, which contains clean water. The bottom part of the sponge body 1 is immersed in the clean water. Two vertical plates 6 are fixedly connected to the pool body 5. The driving roller 3 is coaxially fixedly connected to the rotating shaft 7. The rotating shaft 7 located at the top is rotatably connected to the vertical plate 6. The rotating shaft 7 located at the bottom is rotatably connected to the inner wall of the pool body 5. A rotating motor 8 and a reduction box 31 are installed on one of the vertical plates 6. The output end of the rotating motor 8 is connected to the input end of the reduction box 31. The output end of the reduction box 31 is fixedly connected to one of the rotating shafts 7. The outer walls of the two rotating shafts 7 located at the top are respectively provided with The first gear 9 and the second gear 10 are connected and meshed with each other, and the two sponges 1 are driven by the power of the rotating motor 8 to rotate in opposite directions, so that the sponge 1 in contact with the clean water is soaked, further increasing the sliding friction of the sponge 1 on the surface fluff of the red sand seeds, which is helpful for the fluff stripping of the red sand seeds. At the same time, after the sponge 1 contacts the clean water, the fluff attached to the sponge 1 is also free to detach from the sponge 1 and fall into the clean water, so as to avoid the fluff that has been detached from the red sand seeds from contacting the red sand seeds in the subsequent stripping process for the second time;

[0041] The upper parts of the two vertical plates 6 are fixedly connected to the horizontal plate 11, and the horizontal plate 11 has a horizontal opening 12, and a feed hopper 13 is arranged at the horizontal opening 12. The feed hopper 13 is located just above the two sponge bodies 1, so that the red sand seeds falling from the feed hopper 13 just fall between the two sponge bodies 1;

[0042] The two sides of the blocking block 2 are fixedly connected to the inner wall of the pool body 5, and the middle section has a triangular tip protruding upward, and the triangular tip is located between the two sponge bodies 1;

[0043] A plurality of first guide blocks 14 and second guide blocks 15 are arranged between the two sponges 1. The first guide blocks 14 and the second guide blocks 15 are arranged alternately above the blocking block 2 in sequence. The first guide block 14 is composed of two pieces 16. The two pieces 16 have an upward tip when combined, which is consistent with the tip of the blocking block 2. The second guide block 15 is composed of two pieces 16. The two pieces 16 have a virtual tip along its edge when separated, which is opposite to the tip of the blocking block 2. The plurality of first support blocks 17 are used to arrange the plurality of first guide blocks 14 at a fixed position between the two sponges 1. The plurality of second support blocks 18 are used to arrange the plurality of second guide blocks 15 at a fixed position between the two sponges 1.

[0044] It should be noted that:

[0045] The first support block 17 is between the first guide blocks 14 and is fixedly connected to the first guide blocks 14. The lowest first support block 17 is fixedly connected to the blocking block 2. One end of the second support block 18 is fixedly connected to the vertical plate 6, and the other end is fixedly connected to the second guide block 15. The thickness of the first guide block 14 and the second guide block 15 are the same as that of the blocking block 2. The contact parts of the sponge body 1 and the first guide block 14 and the second guide block 15 are compressed and deformed toward the sponge body 1.

[0046] The plurality of first guide blocks 14 and the plurality of second guide blocks 15 are arranged alternately between the two sponges 1 in sequence, so that the red sand seeds falling from the feed hopper 13 will be dispersed and arranged at different heights between the two sponges 1 for fluff stripping treatment after passing through the first guide block 14 and the second guide block 15, and the red sand seeds concentratedly falling from the feed hopper 13 will be dispersed and distributed between the two sponges 1 on the first guide blocks 14 and the second guide blocks 15 for fluff stripping treatment, thereby avoiding the red sand seeds from being concentrated on the blocking block 2 for fluff stripping treatment, and further preventing the fluff stripping of the red sand seeds from being insufficient. Furthermore, since the red sand seeds move downward with the two sponges 1, the red sand seeds complete a fluff stripping treatment after passing through the first guide block 14, and then complete a fluff stripping treatment again after passing through the second guide block 15, and continue to move downward in sequence until the last fluff stripping treatment is completed after passing through the blocking block 2, thereby achieving multiple stripping treatments for the fluff of the red sand seeds, and the fluff falls off more fully.

[0047] Specifically, the red sand seed moves downward with the two sponges 1, passes through the first guide block 14, and gradually moves toward the sides of the sponge 1 along the downward slanting direction of the first guide block 14, and passes through the second guide block 15 and gradually moves toward the center of the sponge 1 along the downward slanting direction of the second guide block 15;

[0048] The first gear 9 is fixedly sleeved on its corresponding rotating shaft 7, and the second gear 10 is slidably sleeved on its corresponding rotating shaft 7. The second gear 10 is coaxially fixedly connected to the first sleeve ring 19, and the inner diameter of the first sleeve ring 19 is the same as the outer diameter of the rotating shaft 7. The outer wall of the rotating shaft 7 is fixedly connected to the limit block 20, and a limit groove 21 is provided in the first sleeve ring 19. The limit block 20 and the limit groove 21 are slidably connected. The outer wall of the rotating shaft 7 is fixedly sleeved with a first fixing ring 22 and a second fixing ring 23, and a compression spring 24 is sleeved on the outer wall of the rotating shaft 7. The two ends of the compression spring 24 are respectively connected to the first fixing ring 22 and the first sleeve ring 19. Under the elastic action of the compression spring 24, the first sleeve ring 19 and the second gear 10 move in a direction away from the first fixing ring 22 and stop at a position where they contact the second fixing ring 23;

[0049] A second ring 25 is disposed outside the first ring 19 , and the second ring 25 is fixedly connected to the vertical plate 6 . The outer wall of the first ring 19 is fixedly connected to a guide rod 26 . A guide groove 27 is provided in the second ring 25 , and the guide rod 26 is located inside the guide groove 27 . The guide groove 27 consists of an annular groove 28 , an inclined groove 29 and a straight groove 30 .

[0050] A red sand indoor cultivation device comprises the red sand seed fluff stripping component.

[0051] Working principle:

[0052] The rotating motor 8 is started to drive the rotating shaft 7 to rotate, thereby driving the two sponges 1 to rotate at a uniform speed;

[0053] The red sand seeds fall between the two sponges 1 through the feed hopper 13, and gradually move downward with the sponge 1, and complete the fluff stripping process when passing through the first guide block 14, the second guide block 15 and the blocking block 2, and fall into the pool 5 under the guidance of the blocking block 2;

[0054] The rotating shaft 7 drives the first gear 9 and the second gear 10 to rotate synchronously and oppositely, so that the guide rod 26 rotates in the guide groove 27, and passes through the annular groove 28, the inclined groove 29 and the straight groove 30 in turn over and over again. When the guide rod 26 enters the inclined groove 29, the second gear 10 disengages from the meshing with the first gear 9, so that one of the sponges 1 temporarily stops running and rotating. When the guide rod 26 enters the straight groove 30 from the inclined groove 29, under the elastic action of the compression spring 24, the guide groove 27 returns to the annular groove 28 again, and the second gear 10 approaches the first gear 9 again, and meshes with the teeth of the first gear 9 again, so as to realize the rotation of the red sand seeds between the two sponges 1, thereby completely completing the fluff stripping process of the red sand seeds.

[0055] The concept of the present invention is:

[0056] The red sand seeds are stabilized, and the sponge 1 slides relative to the surface of the red sand seeds to generate sliding friction to achieve fluff removal, thereby replacing the traditional manual rubbing method to remove the fluff, thereby improving the efficiency of fluff removal of the red sand seeds;

[0057] By utilizing the intermittent meshing connection between the first gear 9 and the second gear 10, during the period when the first gear 9 and the second gear 10 are not meshing, one of the sponges 1 stops while the other sponge 1 continues to move, thereby realizing the flipping of the red sand seeds and completing the depilation treatment of the entire surface of the red sand seeds.

[0058] Description of the accompanying drawings:

[0059] Attached Figure 4 The thick arrows on both sides of the sponge 1 indicate the movement of the sponge 1 in the downward direction, and the thin arrows indicate the movement of the red sand seeds falling between the two sponges 1 under the guidance of the first guide block 14 and the second guide block 15;

[0060] Attached Fig. 9 , where A represents the red sand seed located between the two sponges.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
