Description

Technical Field

[0001] The utility model belongs to the field of agricultural production, and in particular relates to a wheat seed selection and processing device for a large wheat field. Background Art

[0002] Large-scale wheat fields are of great significance in ensuring food security, promoting agricultural modernization, and improving economic benefits. Wheat seeds are the key factor in wheat field yield. High-quality wheat seeds have a high germination rate, which can ensure that most seeds can germinate smoothly under suitable conditions, and the basic number of seedlings is guaranteed. In addition, high-quality wheat seeds have sufficient nutrients and full endosperm, which can provide rich nutrients for the early growth of seedlings, so that the seedlings have developed root systems, broad and thick leaves, dark green leaves, and strong stress resistance. They can better resist the influence of adverse environmental factors such as low temperature, drought, diseases and insect pests, laying a solid foundation for later growth and development. Large-scale wheat fields are usually located in plains, with tens of thousands of acres, mechanical ridges, and consistent depth. In order to facilitate unified management of wheat during the growing period and unified harvesting after maturity, it is necessary to ensure the consistency of wheat seed particle size. Secondly, viruses and insect eggs that may exist or be carried on the surface of wheat seeds will cause abnormal growth of wheat, thereby reducing the quality and yield of wheat. Existing wheat seed selection devices usually separate the seed soaking process, which is inefficient and difficult to adapt to the scale of wheat fields. Secondly, soaking and feeding need to be carried out alternately, which cannot achieve continuous operation and causes a waste of time. In addition, traditional soaking pools are prone to residual wheat seeds during seeding, and the unreasonable bottom structure design leads to incomplete drainage, affecting the efficiency of subsequent batch processing.

The purpose is to control the wheat seeds to enter the corresponding soaking pool 6 according to the load and working conditions of the soaking pool 6. If one of the soaking pools 6 is saturated with load, it will take a certain amount of time for the soaking pool 6 to soak and clean the wheat seeds. At this time, the rotatable diverter plate 37 is rotated to adjust the wheat seeds to enter the other soaking pool 6. This does not delay the work of the utility model and improves the work efficiency. The wheat seeds with a size smaller than the second sieve 24 and larger than the aperture of the first sieve 23 roll into the corresponding first feed port 33 from the lower end of the first sieve 23, and then in the material guide diverter trough 3, they are discharged from the first material guide port 34 or the second material guide port 35 to the wheat seed integrated processing assembly according to the position of the rotatable diverter plate 37.

[0038] The wheat seed integrated processing component includes a bearing support structure 5, a soaking tank 6, a quick-dissolving diversion agent box 7, and a stirring mechanism 8; the bearing support structure 5 includes a bearing frame 51, a storage plate 52, and a bearing frame 53. The storage plate 52 is arranged in the middle of the bearing frame 51, and a bearing frame 53 is arranged above the bearing frame 51. The bearing frame 53 is a quadrilateral frame structure, and the bearing frame 53 carries the soaking tank 6; the soaking tank 6 includes a feed guide plate 61, a wheat discharge butterfly valve 62, a transmission shaft sealing channel 64, a drainage ball valve 66, and a wheat filter net 67; a feed guide plate 61 is arranged on the upper part of the soaking tank 6, the middle part of the soaking tank 6 is a rectangular structure, a wheat discharge butterfly valve 62 with a valve outlet downward is installed on the bottom edge of the soaking tank 6, and the lower side of the soaking tank 6 is a groove The structure has two sides of the bottom that are inclined and converge toward the middle, and the middle part of the structure is inclined toward the direction of the wheat discharge butterfly valve 62. A transmission shaft sealing channel 64 that runs through the bottom of the soaking tank 6 is provided at the central position of the soaking tank 6. A drainage ball valve 66 is provided below one side of the soaking tank 6 that is close to the wheat discharge butterfly valve 62 in the vertical direction, and a wheat filter net 67 is provided at the front side of the water inlet of the drainage ball valve 66; the instant diversion medicine box 7 is fixedly installed on the feed guide plate 61 provided on the upper part of the soaking tank 6, and the instant diversion medicine box 7 includes a fixed splint 71, a medicine box 72, an anti-overflow sealing ring 73, a water inlet interface 74, a water outlet interface 75, a fine filter net 76, and a coarse filter net 77. The medicine box 72 is fixed on the fixed splint 71, and the lid of the medicine box 72 can be opened The medicine box 72 is provided with an anti-overflow sealing ring 73 on the upper side thereof, a water inlet interface 74 connected to the medicine box 72 is provided on the rear side thereof, a water outlet interface 75 connected to the medicine box 72 is provided on the front side thereof, a fine filter screen 76 is provided on the side of the medicine box 72 near the water outlet interface 75, and a coarse filter screen 77 is provided on the rear side of the fine filter screen 76 inside the medicine box 72; the function of the quick-dissolving diversion medicine box 7 is to add water and medicine to the soaking pool.

The medicine is fully and evenly integrated into the water through the water pressure and the filter screen, so as to provide a uniform liquid medicine environment for the wheat seed soaking. 73 ensures that water will not overflow when water flows through the medicine box 72; the design of the soaking pool 6 is such that when the drain ball valve 66 is opened, the water or liquid medicine will be discharged from the drain ball valve 66 at a relatively low position. During the discharge process, since the wheat filter net 67 is arranged at the front side of the water inlet of the drain ball valve 66, the wheat will not be discharged; when the wheat butterfly valve 62 is opened, since the wheat butterfly valve 62 is located at the bottom and the two sides of the bottom of the soaking pool 6 are inclined and converge toward the middle, the middle part is inclined toward the direction of the wheat butterfly valve 62, the wheat seeds will be discharged from the wheat butterfly valve 62 first. The valve used for wheat discharge here is a butterfly valve. When the butterfly valve is opened, the opening expands instantly, and the wheat seeds are more easily and quickly discharged under the influence of gravity. This design is conducive to the practicality of the utility model;The stirring mechanism 8 is fixedly mounted on the storage plate 52 set in the middle position of the carrier frame 51. The stirring mechanism 8 includes a DC motor 81, a coupling 82, a horizontal transmission shaft 83, a vertical transmission shaft 84, a bevel gear box 85, a first bevel gear 86, a second bevel gear 87, and an agitator 88.

The horizontal transmission shaft 83 passes through the horizontal bearing inside the bevel gear box 85, and the other end thereof is installed with the first bevel gear 86. The vertical transmission shaft 84 passes through the vertical bearing inside the bevel gear box 85, and the lower end thereof is provided with the second bevel gear 87. The first bevel gear 86 and the second bevel gear 87 are meshed with each other. The upper part of the vertical transmission shaft 84 passes through the transmission shaft sealing channel 64, and the upper end thereof is fixed with an agitator 88. The agitator 88 can rotate with the vertical transmission shaft 84. The rotation of the agitator 88 makes the wheat seeds and the soaking liquid Full contact and mixing ensure that each wheat seed can evenly contact the liquid medicine, improve the treatment effect of the liquid medicine on the wheat seeds, better play the role of the liquid medicine in preventing and controlling pests and diseases and promoting seed germination. During the stirring process, the wheat seeds are constantly rolling in the liquid, which helps to remove dust, impurities and possible pathogens on the surface of the wheat seeds, play a role in cleaning the wheat seeds, and further improve the purity and quality of the wheat seeds; the DC motor 81 here can provide a large torque during the startup and operation process. When stirring the wheat seeds, when the number of wheat seeds is large or the concentration of the soaking liquid is large, sufficient torque is required to overcome the resistance of the liquid and the friction between the wheat seeds, ensure that the stirrer 88 can operate normally, and fully mix the wheat seeds with the soaking liquid, reflecting the rationality of the mechanism of the utility model; in this example, the stirrer 88 includes a plurality of cylinders with domes, and this flexible design will not damage the wheat seeds during stirring. ;

[0039] The discharging chute 4 comprises a second feed port 41, a wedge-shaped channel 42, a discharging channel 43, and a connecting block 44; the discharging chute 4 is fixedly arranged above the guide diversion trough 3 through the connecting block 44, and its second feed port 41 corresponds to the lower end of the second screen 24 of the vibrating screen 2; the wheat seeds whose size is larger than the aperture of the second screen 24 roll into the corresponding second feed port 41 from the lower end of the second screen 24, and then the wheat seeds are discharged from the discharging channel 43 through the wedge-shaped channel 42 and collected by corresponding containers. The wheat here is not suitable as large-scale field wheat seeds, which is not conducive to the unified management of wheat fields and the consistency of wheat seeds. It can be collected and used for pastry or feed making.

[0040] The first feed port 33 of the material guiding and diverting trough 3 corresponds to the lower end of the first screen 23 of the vibrating screen 2; it should be noted here that the corresponding positions of the two should satisfy the requirement that the vibrating screen 2 does not interfere with the first feed port 33 when working. In actual situations, the position of the first feed port 33 or the shape of its opening can be adjusted to make the two fit together.

[0041] The rotatable diverter plate 37 includes a knob 371, a rotating body 372, and a rectangular plate 373; the knob 371, the rotating body 372 and the rectangular plate 373 are an integrated structure, wherein the end of the rectangular plate 373 away from the knob 371 is provided with chamfers on both sides in the vertical direction, and the chamfers on both sides can respectively fit with the left and right inner walls of the diverter trough 32 after the rotatable diverter plate 37 is rotated, wherein the knob 371 is a symmetrical structure in the horizontal direction, and its symmetry axis is parallel to the horizontal symmetry axis of the rectangular plate 373; the purpose is to distinguish the position of the rectangular plate 373 from the outside of the material guide diverter trough 3 by observing the position of the knob 371, so as to facilitate the adjustment of its diversion direction, which is beneficial to the practicality of the utility model.

A notch projected as a rectangle is provided on the side of the knob assembly hole 36 close to the first feed port 33. The rectangular plate 373 passes through the notch and can move along the horizontal direction of the notch. The arrangement here can make the rotatable diverter plate 37 rotate in the diverter slot 32, so that it can play the role of diverting and guiding materials. Its rotation works as shown in FIG. Figure 7 shown.

[0043] The mesh size of the first sieve 23 of the vibrating screen 2 is smaller than that of the second sieve 24, and the mesh number of the first sieve 23 is between 16 and 20 meshes. The wheat seeds screened out by the first sieve 23 are used for large-scale field sowing, and the advantage of the mesh number of the first sieve 23 being between 16 and 20 meshes is that the wheat seeds screened out by the sieve with this mesh number are relatively uniform in size and relatively regular in shape. When the seeder is used for sowing, the wheat seeds can pass through the seeding device of the seeder more smoothly, reducing the occurrence of problems such as seed jamming and seed leakage, ensuring the uniformity and accuracy of sowing, and improving the operation efficiency and sowing quality of the seeder. In addition, the uniformity is better and the subsequent processing is more convenient. In the soaking stage, the wheat seeds with oversized particles have a large volume and a relatively small contact area with the agent, so longer soaking time or stronger stirring force may be required to ensure that the agent is fully absorbed. The wheat seeds screened out by the mesh number of the first sieve 23 being between 16 and 20 meshes can be mixed with the agent more quickly and evenly, thereby improving the soaking efficiency.

[0044] Two bearings are sleeved in sequence on the upper part of the vertical transmission shaft 84 of the stirring mechanism 8, and the two bearings are sleeved inside the transmission shaft sealing channel 64; this arrangement is used to utilize the stability of the stirring mechanism 8 when working and the structural rationality of the utility model.

[0045] A lip-shaped sealing ring 65 is provided at the upper end of the transmission shaft sealing channel 64 of the soaking tank 6; an annular sealing ring 63 matching with the one provided at the valve inlet of the wheat discharge butterfly valve 62 and the drainage ball valve 66; the lower bottom surface of the soaking tank 6 is rectangular; the sealing ring is provided to prevent water, liquid medicine, wheat seeds and other substances in the soaking tank 6 from leaking out along the gap between the transmission shaft and the transmission shaft sealing channel 64, thereby ensuring that the liquid environment in the soaking tank 6 is relatively closed and the wheat seed processing process proceeds normally. The lip-shaped sealing ring 65 has good sealing performance and is usually used in situations where sealing needs to be maintained in a dynamic environment. The annular sealing ring 63 is usually used in a static environment where the pipeline is connected. Here, the lip-shaped sealing ring 65 and the annular sealing ring 63 are conducive to the structural rationality and practicality of the utility model.

[0046] The bearing support structure 5 also includes two support blocks 54 arranged on the placement plate 52, the bottom of the support block 54 is fixed on the placement plate 52, and the upper part of the support block 54 is against the lower bottom surface of the immersion pool 6 to provide supporting force; the inner sides of the front and rear frames of the bearing frame 53 arranged above the bearing support structure 5 are provided with chamfers that fit with the bottom surface of the immersion pool 6. The bearing mechanism designed here is simple and has high stability, which is conducive to the stability of the utility model.

[0047] Specific working principle: Before starting work, first prepare an appropriate amount of medicine and put it into the quick-dissolving diversion medicine box 7, specifically put it in the position between the coarse filter screen 77 and the water inlet interface 74 in the medicine box 72, and then buckle the medicine box 72, connect the water source, and the water flows from the water inlet interface 74 through the medicine box 72 and flows out from the water outlet interface 75 to the soaking pool 6. The lowest water level of the water flow is until the agitator 88 is submerged. In this process, the medicine is fully and evenly integrated into the water through the water pressure and the filter screen, and the asynchronous motor 26 is started, and the vibrating screen 2 starts to work. , wheat seeds are placed on the upper end of the second sieve 24, and the wheat seeds with a size larger than the aperture of the second sieve 24 roll into the second feed port 41 corresponding thereto from the lower end of the second sieve 24, and then the wheat seeds are discharged from the discharge channel 43 through the wedge-shaped channel 42 and collected by a corresponding container. The wheat here is not suitable for large-scale field wheat seeds, which is not conducive to the unified management of the wheat fields and is not convenient for unified soaking. It can be collected and used for pastry or feed making; the wheat seeds with a size smaller than the second sieve 24 and larger than the aperture of the first sieve 23 roll into the second feed port 41 corresponding thereto from the lower end of the first sieve 23. The corresponding first feed port 33 is then formed in the material guide and diverter trough 3, and one side chamfer of the rectangular plate 373 in the vertical direction is fitted with the left inner wall of the diverter trough 32, and the wheat seeds are discharged from the first material guide port 34 into the right soaking pool 6; the DC motor 81 of the right soaking pool 6 is started, and the stirring mechanism 8 starts to work, specifically, the output shaft of the DC motor 81 drives the horizontal transmission shaft 83 to rotate, and the horizontal transmission shaft 83 drives the second bevel gear 87 to rotate through the first bevel gear 86 at its end, and then drives the vertical transmission shaft 84 to rotate, and the vertical transmission shaft 84 rotates The stirrer 88 is driven to start rotating. During the stirring process, the wheat seeds are fully cleaned and soaked. It is more appropriate to soak the wheat seeds in the liquid medicine for 15-30 minutes. The specific stirring frequency and time can be adjusted according to the number of wheat seeds, the type of liquid medicine and the total soaking time. After soaking, the drain ball valve 66 is opened, and the liquid medicine is discharged from the drain ball valve 66. The wheat seeds can be cleaned with water and then the wheat butterfly valve 62 is opened. The cleaned and soaked wheat seeds are discharged from the valve port of the wheat butterfly valve 62, and collected in a corresponding container for subsequent wheat seed drying.

[0048] During the above work, after the right soaking pool 6 is saturated with wheat seeds, the knob 371 is turned clockwise by hand, and the knob 371 drives the rotating body 372 and the rectangular plate 373 to rotate clockwise, so that one side chamfer of the rectangular plate 373 in the vertical direction is in contact with the right inner wall of the diverter trough 32. At this time, the wheat seeds are discharged from the second material guide port 35 into the left soaking pool 6. After the right soaking pool 6 performs the soaking and cleaning work of the wheat seeds, the drainage ball valve 66 and the wheat drainage butterfly valve 62 are closed to add liquid medicine, and prepare for the next soaking and cleaning work. In this way, the two integrated wheat seed processing devices work alternately, which is beneficial to improving the working efficiency of the utility model.

[0049] During operation, wheat seeds with a size smaller than the aperture of the first screen 23 fall below the box 22 and are discharged from the discharge port 25; they are collected in corresponding containers. The wheat seeds that are too small or not full enough can be used as feed.
