Description

Technical Field

[0001] The present invention relates to the technical field of seed water selection, and specifically to an automatically separating seed water selection device for plant cultivation. Background Art

[0002] The Chinese invention patent with the publication number CN108855580B discloses an automatically separating cereal seed water selection device for agricultural planting. Through the up and down movement of the piston push plate and the arrangement of the water permeable holes, the grains at the bottom oscillate in water, so that the shriveled seeds at the bottom can float up. At the same time, as the liquid level rises, the floating seeds will be discharged from the inside of the water selection box, preventing the shriveled seeds at the bottom from being pressed and unable to float, thereby realizing the automatic separation of the shriveled seeds and the qualified seeds. The structure is simple and the practicability is strong.

[0003] The Chinese invention patent with the publication number CN108745611B discloses a tobacco seed water selection device. When the movable plate moves downward, the baffle flips upward under the action of water pressure. The unqualified seeds floating on the water layer enter the upper side of the movable plate through the through holes. When the movable plate moves upward, the baffle closes under the action of the spring to block the through holes. The water containing unqualified seeds moves upward under the action of the movable plate, then enters the filtering cavity through the conduit, and after being filtered by the conical filter screen, the water re-enters the water selection cavity through the suction force generated at the lower end of the water selection cavity by the upward movement of the movable plate, thereby achieving the effect of water conservation. The rotating shaft drives the stirring rod to rotate through the rotating rod, thereby stirring the seeds, which can improve the seed water selection effect and prevent some unqualified seeds from not floating due to stacking.

[0004] In related technologies, most of the existing seed water washing methods are to place the seeds into a container filled with water source, and separate the plump seeds and the shriveled seeds through the water source. However, after the water washing device of this method washes the seeds, it is necessary to separate and export the qualified and unqualified seeds before the next round of water selection work can be carried out. Moreover, when separating and exporting, generally the water source is exported, which increases the water resource demand, improves the water selection cost of batch seeds, lacks the function of continuous water selection, and thus reduces the water selection efficiency of batch seeds.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1:

[0038] Refer to the attached Figure 1-10, a seed water selection device for automatic separation for plant cultivation, comprising a water selection tank 1, a U-shaped guide hopper 2 is fixedly connected to one side of the top of the water selection tank 1, a partition plate 3 is fixedly connected to the bottom of the inner wall of the water selection tank 1, an inclined filter plate 4 is fixedly connected between the top of the partition plate 3 and the inner side of the water selection tank 1, a baffle plate 5 is fixedly connected to the inside of the water selection tank 1, a boiling component 6 for surging the water source inside the water selection tank 1 is arranged on one side of the water selection tank 1, a material discharge component 7 is arranged inside the water selection tank 1, the material discharge component 7 is located on one side of the baffle plate 5, a material loading component 8 is arranged on the other side of the top of the water selection tank 1, and two transmission components 9 for horizontally driving the loading end of the loading component 8 are arranged on the top of the water selection tank 1, and the two transmission components 9 are both connected to the material discharge component 7 in a transmission manner;

[0039] The partition plate 3 and the filter plate 4 are arranged to separate the bottom of the inner wall of the water selection tank 1 into a filter cavity, which is not only convenient for the precipitation of qualified seeds, but also convenient for the subsequent boiling component 6 to surge the seeds. The baffle plate 5 is arranged to divide the feeding component 7 to prevent the inferior seeds above the liquid surface from contacting the feeding component 7, thereby forming a qualified seed export effect;

[0040] By setting the water selection tank 1, the seeds can be water-selected. By setting the boiling component 6, not only can the seeds inside the water selection tank 1 be surged, so that the seeds in the water selection tank 1 are dispersed and surged to improve the water selection effect, but also the seeds after water selection can be surged and driven to the unloading component 7 to form an export operation.

[0041] The seeds after water selection can be exported through the unloading component 7, which has the function of continuous water selection, solving the problem that the water selection device in the prior art can only perform water selection on a specified amount of seeds, and after the water selection is completed, the separated seeds need to be exported before the next round of water selection can be carried out. The lack of continuous water selection function reduces the water selection efficiency and cannot meet the water selection work of batch seeds;

[0042] The seeds discharged from the feeding assembly 7 are discharged through the U-shaped guide hopper 2, and the shriveled seeds can be uniformly discharged according to the stored amount after multiple water selections.

[0043] See attached Figure 5-7The material unloading assembly 7 includes a transmission roller 71 which is rotatably connected to the inside of the water selection tank 1 and is rotatably connected to the top of the water selection tank 1 through a bracket. The outer surfaces of the two transmission rollers 71 are connected by a transmission belt 72. The transmission belt 72 is provided with a plurality of filter holes. The outer surface of the transmission belt 72 is fixedly connected with a plurality of rubber toggle plates 73. The transmission belt 72 is arranged in an inclined shape and is located on the inner side of the baffle 5. The top of the water selection tank 1 is fixedly connected with a first motor 74 through a bracket. The output shaft of the first motor 74 is fixedly connected with one end of one of the transmission rollers 71. The top of the U-shaped guide hopper 2 is provided with a material-pickup member which is transmission-connected with one of the transmission rollers 71.

[0044] The plurality of toggle plates 73 are provided to improve the friction of the transmission belt 72, and then the seeds are guided out through the rotation of the transmission belt 72. The toggle plates 73 are made of rubber material, which not only has a good material-sliding performance, but also facilitates the impact and twisting of the material-sliding piece. Combined with the reset elasticity of the rubber material, shaking is formed, which facilitates the adhered seeds to fall off, thereby improving the guiding effect.

[0045] By opening a plurality of filter holes inside the transmission belt 72, water and seeds can be separated during the material guiding process, thereby improving the integrity of the seed guiding;

[0046] The first motor 74 is connected to an external power source and a control switch, and is used to drive one of the transmission rollers 71 to rotate, and then drive the transmission belt 72 to rotate. The rotation of the transmission belt 72 can drive a number of toggle plates 73 to rotate in a circle, and then the qualified seeds can be toggled upward to form a material guiding operation, so as to facilitate continuous water selection. In addition, the material toggle piece is set to toggle the toggle plate 73 during the material guiding process to avoid the problem of seed adhesion, thereby improving the material guiding effect.

[0047] See attached Figure 5-7 The material-dispensing member includes a rotating shaft 75 rotatably connected to the top of the U-shaped guide hopper 2 through a bracket, a plurality of impact blocks 76 are fixedly connected to the outer surface of the rotating shaft 75, and the outer surfaces of both ends of the rotating shaft 75 and the outer surfaces of both ends of one of the driving rollers 71 are fixedly connected to pulleys 77, and the two sets of pulleys 77 are connected by belt transmission;

[0048] The rotating shaft 75 is connected to one of the driving rollers 71 through two sets of pulleys 77, so that when the driving roller 71 rotates, it can synchronously drive the rotating shaft 75 to rotate, and then drive several impact blocks 76 to rotate. Through the synchronous rotation of the impact block 76 and the transmission belt 72, the impact block 76 can collide with the toggle plate 73 on the transmission belt 72, so that the seeds adhered to the toggle plate 73 can be quickly exported, thereby improving the export effect and having the function of automatic material extraction.

[0049] Refer to the attached Figure 4 , the boiling assembly 6 includes a sleeve 61 fixed to one side of the water separation tank 1, a filter box 62 fixed to the top side of the filter plate 4, the inside of the sleeve 61 is communicated with the inside of the filter box 62 through a first branch pipe 63, the bottom of the sleeve 61 is fixedly communicated with a second branch pipe 64, the other end of the second branch pipe 64 extends to the bottom of the filter plate 4, and a row of outlet pipes 65 are fixedly communicated with the outer surface of the second branch pipe 64. A plurality of nozzles are arranged on the outer surface of the row of outlet pipes 65, and a water source driving member is arranged inside the sleeve 61;

[0050] Through the arrangement of the water source driving member, the water source inside the water separation tank 1 can be absorbed into the inside of the sleeve 61 through the first branch pipe 63 or the second branch pipe 64, and the water source inside the sleeve 61 can be discharged into the inside of the water separation tank 1 through the first branch pipe 63 or the second branch pipe 64, forming the seed surging and dispersing work and the guiding work of the seeds, further improving the functionality and practicability of the boiling assembly 6.

[0051] Refer to the attached Figure 4 , the water source driving member includes a piston plate 66 slidably connected to the inside of the sleeve 61 through a sealing sleeve. A telescopic electric rod 67 is fixedly connected to the outer surface of the sleeve 61 through a bracket. The telescopic end of the telescopic electric rod 67 is fixedly connected to a connecting plate 68. A movable rod 69 is fixedly connected to the bottom of the connecting plate 68. The bottom end of the movable rod 69 extends into the inside of the sleeve 61, and the bottom end of the movable rod 69 is fixed to the top of the piston plate 66;

[0052] The telescopic electric rod 67 is connected to an external power source and a control switch, and is used to drive the connecting plate 68 to move up and down. Through the up and down movement of the connecting plate 68, the piston plate 66 can be driven to move up and down through the movable rod 69. Through the downward movement of the piston plate 66, the water source at the bottom of the sleeve 61 can be squeezed into the inside of a plurality of outlet pipes 65 and ejected through the nozzles on the plurality of outlet pipes 65, forming a way for the water source to surge from bottom to top, forming the water source boiling work, and then the seeds deposited on the top of the filter plate 4 can be driven to improve the dispersion effect of the seeds, avoid the inferior seeds that precipitate from floating, improve the water separation effect. When the piston plate 66 moves downward, a negative pressure can be formed at the top of the sleeve 61. At this time, the water source inside the water separation tank 1 can be sucked through the first branch pipe 63;

[0053] Instead, through the upward movement of the piston plate 66, the absorbed water source can be pushed out through the first branch pipe 63. The seeds deposited on the top of the filter plate 4 are moved to one side through the filter frame 62, so that the qualified seeds are stacked on the blanking assembly 7, facilitating the subsequent export of the seeds. It not only has the function of seed surging, but also can drive the qualified seeds to the position of the blanking assembly 7, thereby improving the convenience of its blanking.

[0054] The working principle of the automatic separation seed water selection device for plant cultivation of the present invention is as follows:

[0055] Through the setting of the feeding assembly 8, the seeds to be water selected are discharged into the interior of the water selection tank 1. Through the water source inside the water selection tank 1, the seeds can be separated into plump qualified seeds and shriveled inferior seeds, and the qualified seeds settle on the top of the filter plate 4, while the inferior seeds float on the liquid surface of the water source;

[0056] By starting the electric telescopic rod 67, the piston plate 66 can be driven to move up and down through the connecting plate 68 and the movable rod 69. Through the downward movement of the piston plate 66, the water source at the bottom of the sleeve 61 can be squeezed into the interior of several outlet pipes 65, and is pushed out through the nozzles on the several outlet pipes 65, forming a way for the water source to surge from bottom to top, forming a boiling working state of the water source. When the piston plate 66 moves downward, the negative pressure at the top of the sleeve 61 can suck the water source inside the water selection tank 1 through the first branch pipe 63;

[0057] Through the upward movement of the piston plate 66, the absorbed water source can be pushed out through the first branch pipe 63. The seeds deposited on the top of the filter plate 4 are moved to one side through the filter frame 62, and the qualified seeds are surging and stacked on the blanking assembly 7. When the piston plate 66 moves upward, the negative pressure at the bottom of the sleeve 61 can absorb water through the second branch pipe 64, thus forming a two-way surging working state;

[0058] By starting the first motor 74, one of the transmission rollers 71 can be driven to rotate, and then the transmission belt 72 can be driven to rotate, and then several stirring plates 73 can be driven to rotate in a circle. Finally, the qualified seeds can be pushed upward and finally exported through the U-shaped material guiding hopper 2;

[0059] The rotating shaft 75 is driven by two sets of belt pulleys 77 to be connected with one of the transmission rollers 71. When the transmission roller 71 rotates, the rotating shaft 75 can be synchronously driven to rotate, and then several impact blocks 76 can be driven to rotate. Through the synchronous rotation of the impact blocks 76 and the transmission belt 72, the impact blocks 76 can impact the stirring plates 73 on the transmission belt 72, so as to quickly separate the seeds adhered to the stirring plates 73.

[0060] Example 2: Different from Example 1;

[0061] Refer to the appendix Figure 9-10 , the feeding component 8 includes a silo 81 fixed to the other side of the top of the water separation tank 1 through a bracket. A metering member is provided at the bottom of the silo 81. The bottom of the metering member is fixedly communicated with a flexible material guiding frame 82. The bottom of the flexible material guiding frame 82 is fixedly communicated with a material guiding nozzle 83;

[0062] Through the setting of the silo 81, the seeds to be water-separated can be stored, so as to convey a specified amount of seeds to the water separation tank 1 through the flexible material guiding frame 82 and the material guiding nozzle 83 to form a water separation operation. The flexible material guiding frame 82 is a material guiding frame made of flexible materials in the prior art, such as rubber material, cloth, etc., so as to drive the material guiding nozzle 83 to reciprocate left and right by the transmission component 9 to form a large-range feeding operation;

[0063] The metering member includes a material distribution cylinder 84. The inside of the material distribution cylinder 84 is communicated with the inside of the silo 81 through a feeding frame. The top of the flexible material guiding frame 82 is fixedly communicated with the inside of the material distribution cylinder 84. A rotating shaft 85 is rotatably connected inside the material distribution cylinder 84. A plurality of material distribution plates 86 are fixedly connected to the outer surface of the rotating shaft 85. A second motor 87 for driving the rotation of the rotating shaft 85 is fixedly connected to the front of the material distribution cylinder 84;

[0064] By fixedly connecting a plurality of material distribution plates 86 to the outer surface of the rotating shaft 85, the internal space of the material distribution cylinder 84 can be divided into several partition chambers through the plurality of material distribution plates 86. The seeds are quantitatively stored through the several partition chambers, so as to form a metering feeding operation through the rotation of the rotating shaft 85. The number of the material distribution plates 86 is at least two;

[0065] The second motor 87 is connected to an external power supply and a control switch, and is used to drive the rotation of the rotating shaft 85. Through the rotation of the rotating shaft 85, several material distribution plates 86 can be driven to rotate, and then the seeds in each partition chamber can be discharged into the flexible material guiding frame 82 to form a feeding operation, which has the function of metering feeding, and solves the problem that the feeding method in the prior art is prone to overfeeding or underfeeding, which not only easily reduces the water separation efficiency, but also easily increases the water separation load, thereby affecting the water separation effect.

[0066] Example 3: Different from Example 1;

[0067] Refer to the appendix Figure 8, the transmission component 9 includes a sliding block 91 slidably connected to the front surface of the water separation tank 1 and a semi-toothed disc 92 fixed to the outer surface of one end of a transmission roller 71. One side of the sliding block 91 is fixedly connected to a straight tooth plate 93 meshing with the semi-toothed disc 92. The other side of the sliding block 91 is fixedly connected to an L-shaped moving frame 94 through a support rod. The top of the L-shaped moving frame 94 is fixedly connected to the material guiding nozzle 83, and an extrusion member is arranged at the moving end of the L-shaped moving frame 94;

[0068] The semi-toothed disc 92 is a toothed disc with only partial teeth in the prior art. By the rotation of the transmission roller 71 in the blanking component 7, the semi-toothed disc 92 can be driven to rotate. Through the rotation of the semi-toothed disc 92, one side of the straight tooth plate 93 can be driven to move, and then one side of the L-shaped moving frame 94 can be driven through the sliding block 91. Finally, one side of the material guiding nozzle 83 in the feeding component 8 can be driven. When the smooth area on the semi-toothed disc 92 rotates to the position meshing with the straight tooth plate 93, the meshing with the straight tooth plate 93 is lost. Through the arrangement of the extrusion member, the straight tooth plate 93 can be extruded and reset, indirectly forming a reciprocating drive on both sides of the material guiding nozzle 83;

[0069] Through the movement of the material guiding nozzle 83 on both sides, the feeding range and dispersion can be improved, solving the problem that the seeds are prone to accumulation when feeding at a specified position, thereby affecting the water separation effect. Moreover, the driving force of blanking is effectively linked and combined, reducing the use of electric driving components and improving the energy conservation and environmental protection performance of the equipment.

[0070] The extrusion member includes a guide rod 95 fixed to the water separation tank 1 through a bracket. The bottom of the L-shaped moving frame 94 is slidably connected to the outer surface of the guide rod 95. An extrusion spring 96 for extruding and resetting the L-shaped moving frame 94 is sleeved on the outer surface of the guide rod 95;

[0071] Through the elastic force of the extrusion spring 96 itself, the L-shaped moving frame 94 after moving to one side can be extruded, so that the L-shaped moving frame 94 is driven to reset, and then a reciprocating drive work on both sides is formed.

[0072] It should be noted that the term "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or elements inherent to such process, method, article or device. Without more limitations, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
