Description

Technical Field

[0001] The present invention belongs to the technical field of wet separation of seeds, and relates to a seed water selection device for forage grass planting. Background Art

[0002] Forage grass planting is an important part of animal husbandry. High-quality forage grass can not only provide the nutrients required by livestock, but also improve the quality of products such as milk and meat. During the process of forage grass planting, the selection and treatment of seeds have a direct impact on the final yield and quality. With the development of agricultural mechanization, more and more automated equipment has been introduced into various links of agricultural production, including the seed water selection process. Seed water selection is a method of separating seeds based on density differences. It utilizes the different characteristics of seeds with different qualities floating and sinking in water. High-quality seeds usually sink, while empty, pest-damaged seeds will float.

[0003] Currently, during the process of water selecting seeds, it is usually carried out in a container filled with water. After adding water to the container, the seeds are directly poured in. This method can initially separate some inferior seeds. However, since plump seeds are heavier, they often press down on the light and unplump seeds, resulting in the latter being unable to float normally, affecting the screening efficiency and accuracy. In order to improve the screening effect, the operator needs to constantly stir the seeds, the operation process is rather cumbersome, and continuous stirring by the operator also consumes a lot of manpower.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The present invention will be further described below in conjunction with the drawings and the specific embodiments.

[0027] A seed water selection device for forage planting, as Figures 1-3 shown, which includes a chassis 1, a connection frame 2, a material guiding plate 3, a collection mechanism and a water adding mechanism. The connection frame 2 is connected to the top of the chassis 1. The left side inside the connection frame 2 is connected with a material guiding plate 3. The material guiding plate 3 separates the inside of the connection frame 2. Inside the connection frame 2, there is a collection mechanism for collecting seeds and a water adding mechanism for adding water into the collection frame.

[0028] As Figure 2 and Figure 3 shown, the collection mechanism includes a good seed collection frame 41, a barrier net 42, a baffle 43 and a waste seed collection frame 44. The right side inside the connection frame 2 is connected with a baffle 43. The right side of the connection frame 2 separated by the baffle 43 is a reflux area. Between the lower part on the left side of the baffle 43 and the material guiding plate 3, there is a good seed collection frame 41, which is used for collecting good seeds. The bottom of the good seed collection frame 41 is connected with a barrier net 42. Between the upper part on the right side of the baffle 43 and the right inner wall of the connection frame 2, there is a waste seed collection frame 44, which is used for collecting waste seeds. The waste seed collection frame 44 is located above the reflux area. The top of the waste seed collection frame 44 is slightly lower than the top of the baffle 43. The bottom of the waste seed collection frame 44 is provided with a filter screen 45.

[0029] As Figure 2 and Figure 3 shown, the water adding mechanism includes a water pump 51, a liquid suction pipe 52, a connection cylinder 53, a spray pipe 54 and a liquid injection pipe 55. The bottom on the left side of the connection frame 2 is connected with a water pump 51. The water pump 51 is located below the material guiding plate 3. The liquid inlet end of the water pump 51 is communicated with a liquid suction pipe 52. The liquid suction pipe 52 extends into the reflux area. The upper part on the left side outside the connection frame 2 is installed with a connection cylinder 53. The right side of the connection cylinder 53 is uniformly and spacedly communicated with a plurality of spray pipes 54. The spray pipes 54 extend into the connection frame 2. The spray pipes 54 are located above the material guiding plate 3. A liquid injection pipe 55 is communicated between the connection cylinder 53 and the liquid outlet end of the water pump 51, so that when the water pump 51 operates, it can extract the water in the reflux area through the liquid suction pipe 52 and then inject the water into the connection cylinder 53 through the liquid injection pipe 55.

[0030] When it is necessary to perform water selection on seeds, this device can be used. When in use, first fill the left side of the connection box 2 with water, and then add water to the reflux area so that the water level in the reflux area is below the waste seed collection box 44. At this time, add the seeds to the guide plate 3. After the addition is completed, control the operation of the water pump 51. When the water pump 51 operates, it can extract the water in the reflux area and inject it into the connection cylinder 53 through the liquid injection pipe 55, and finally spray it out through the spray pipe 54. The water sprayed out can spray on the seeds, disperse the seeds, and while dispersing the seeds, it can also wash the seeds to the right. Good seeds, due to their heavier quality, will sink into the water. The seeds that sink into the water will be blocked by the baffle 43 after moving to the right, and finally sink into the good seed collection box 41, and the seeds are collected through the good seed collection box 41. Bad seeds, due to their lighter quality, will float on the water surface and finally move to the right along with the water surface, and then can pass through the baffle 43 and fall into the waste seed collection box 44. The water will pass through the filter screen 45 and enter the reflux area. In this way, water selection treatment can be carried out on the seeds, and during the treatment, the seeds can be dispersed to prevent the seeds from clumping together and affecting the accuracy of water selection.

[0031] As Figure 4 and Figure 5 shown, it further includes an intermittent feeding mechanism. The intermittent feeding mechanism includes side plates 61, a feeding frame 62, a partition plate 63, and an elastic member 64. The left parts of the front and rear sides of the connection box 2 are both provided with side plates 61. A feeding frame 62 is connected between the upper parts of the two side plates 61. Three discharge ports are spaced apart at the bottom of the feeding frame 62. A partition plate 63 is slidably connected between the middle parts of the two side plates 61. The partition plate 63 is located at the bottom of the feeding frame 62. The sliding of the partition plate 63 can block the discharge ports of the feeding frame 62. The partition plate 63 is slidably connected to the feeding frame 62, and an elastic member 64 is connected between the partition plate 63 and the feeding frame 62. The elastic member 64 is a return spring.

[0032] When adding seeds, the seeds can be added to the feeding frame 62. Subsequently, when performing the seed addition work, the partition plate 63 can be intermittently pulled to move to the right. When the partition plate 63 moves, the elastic member 64 is compressed, and then the partition plate 63 is released. Under the action of the elastic member 64, the partition plate 63 returns to its original position. By repeatedly pulling the partition plate 63 to move, the seeds can intermittently pass through the partition plate 63 and fall on the guide plate 3, thereby achieving the effect of intermittent seed addition and avoiding adding too many seeds at one time and affecting the water selection work.

[0033] As Figure 6As shown, it further includes a spraying mechanism. The spraying mechanism includes a pump body 71, an infusion pipe 72, a liquid outlet pipe 73, and a nozzle 74. The pump body 71 is installed at the bottom inside the reflux area. The liquid outlet end of the pump body 71 is communicated with the infusion pipe 72. The infusion pipe 72 passes through the baffle 43 and is located below the barrier net 42. A plurality of liquid outlet pipes 73 are uniformly spaced and communicated with the infusion pipe 72. A plurality of nozzles 74 are uniformly spaced and communicated with the top of the liquid outlet pipe 73, so that when the pump body 71 operates, liquid can be injected into the liquid outlet pipe 73 through the infusion pipe 72.

[0034] After good seeds fall into the good seed collection box 41, the operation of the pump body 71 can be controlled to draw water in the reflux area through the infusion pipe 72, and the water is injected into the nozzle 74 through the infusion pipe 72 and the liquid outlet pipe 73, and then the water is sprayed out through the nozzle 74. The sprayed water can impact the seeds in the good seed collection box 41, disperse the seeds, avoid the situation of seeds clustering together, and also avoid the situation that good seeds are carried by bad seeds and sink into the good seed collection box 41 together, ensuring the accuracy of the screening result.

[0035] As Figure 7 and Figure 8 As shown, it further includes a transmission mechanism. The transmission mechanism includes a turntable 81, an extension block 82, an impeller 83, a convex shaft 84, and a sliding block 85. The left sides of the front and rear side walls inside the connection frame 2 are both rotatably connected with an impeller 83. The spray pipe 54 is aligned with the impeller 83. The impeller 83 is located on the left side of the side plate 61. One side of the two impellers 83 away from each other passes through the connection frame 2 and is connected with a turntable 81. The turntable 81 is connected with an extension block 82. The middle part of the left side of the side plate 61 is slidably connected with a sliding block 85. The sliding block 85 can slide up and down along the side plate 61. A guiding inclined groove is provided on the sliding block 85. Convex shafts 84 are connected to the front and rear sides of the barrier plate 63. The two convex shafts 84 are respectively located in the two guiding inclined grooves. The bottom of the sliding block 85 is inclined. When the extension block 82 rotates, it can contact and squeeze the inclined part of the sliding block 85 to move the sliding block 85.

[0036] When the spray pipe 54 sprays water, the water will impact the impeller 83, causing the impeller 83 to rotate. When the impeller 83 rotates, it can drive the turntable 81 to rotate. When the turntable 81 rotates, it can drive the extension block 82 to rotate. When the extension block 82 rotates, it can contact and squeeze the bottom of the sliding block 85 to move the sliding block 85 upward. When the sliding block 85 moves upward, it will squeeze the convex shaft 84 to move to the right through the guiding inclined groove. When the convex shaft 84 moves, it can drive the barrier plate 63 to move, and the elastic member 64 is compressed. When the extension block 82 rotates to disengage from the sliding block 85, under the action of the elastic member 64, the barrier plate 63 resets. When the barrier plate 63 resets, it can drive the sliding block 85 to reset through the convex shaft 84. Repeating like this can automatically drive the barrier plate 63 to move repeatedly, making the operation more convenient.

[0037] As Figure 9 and Figure 10 shown, it further includes a spraying frame 91 and a connecting pipe 92. The spraying frame 91 is installed on the top of the connecting frame 2, and a connecting pipe 92 is communicated between the spraying frame 91 and the connecting cylinder 53. The water in the connecting cylinder 53 will enter the spraying frame 91 through the connecting pipe 92, and the spraying frame 91 can spray the water from top to bottom on the floating seeds, so as to wash the seeds into the lower part of the connecting frame 2, which can disperse the seeds and make the seeds fully soak in water. If the seeds are bad seeds with light quality, they will still float to the water surface after soaking. If the seeds are good seeds, they will sink into the water.

[0038] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
