Description

Technical Field

[0001] This utility model relates to the field of soil screening and sorting technology, specifically to a vibrating screen soil-type radish harvesting and sorting device. Background Technology

[0002] Radishes are a common vegetable and are widely cultivated. Harvesting is a crucial step in their production, accounting for over one-third of labor and more than half of the total cost. Traditional manual radish harvesting is inefficient and costly, making it difficult to meet the needs of large-scale cultivation. Currently, although radish harvesting machinery has achieved full automation, it still has shortcomings. For example, existing equipment does not thoroughly clean the soil off the radishes, affecting subsequent sorting; the sorting devices have poor adaptability and cannot accurately adapt to radishes of different sizes and shapes; some equipment is prone to damaging radishes during operation, reducing product quality. Against this backdrop, there is an urgent need for a vibrating screen-type radish harvesting and sorting device that uses a telescopic rod and spring to swing and shake the sorting device, efficiently cleaning the soil, accurately sorting radishes, and improving harvesting quality and efficiency.

[0003] Utility model patent CN219377893U discloses a vibrating soil screen, comprising: a base frame; a hopper installed above the base frame, with a feeding chamber inside the hopper; a blade assembly inserted into the bottom of the hopper, with the blades of the blade assembly located inside the feeding chamber; a vibrating screen assembly installed inside the base frame, corresponding to the bottom end of the hopper; and a conveying assembly installed inside the base frame, with one end corresponding to the bottom end of the vibrating screen assembly. The vibrating screen assembly includes: a drive unit installed inside the base frame; a connecting rod unit installed at the bottom of the base frame; and a vibrating screen, with its top corresponding to the bottom end of the hopper, and discharge ports at both the front and rear ends of the bottom of the vibrating screen. The bottom side of the vibrating screen is connected to the connecting rod unit, and the rear end of the vibrating screen is connected to the drive unit. This utility model solves the technical problems of existing vibrating soil screens having complex structures and narrow application ranges.

[0004] Although the vibrating soil screener is convenient for vibrating and screening soil from radishes and has excellent screening effect, the device still has the following problems in actual use: rigid vibration can easily damage the radishes, and it cannot sort radishes by size. In view of this, we propose a vibrating soil screener-type radish harvesting and sorting device. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a vibrating screen soil-type radish harvesting and sorting device.

[0006] In a first aspect, this application provides a vibrating screen for harvesting and sorting radishes, including a base, the base including a bottom plate, two parallel side plates vertically mounted on the top surface of the bottom plate, a plurality of springs arranged in a matrix fixedly mounted on the opposing side of the two side plates, and vertically mounted vertical rods fixedly mounted on the opposing side of the two side plates, a screen box with the same top opening connected between the two side plates, a vibrating motor fixedly mounted on the outer side wall of the screen box near the two side plates, an elliptical block coaxially connected to the top surface of the output shaft of the vibrating motor, a feed plate fixedly mounted on the top surface of one side wall of the screen box, a plurality of inclined screen roller groups installed from top to bottom inside the screen box, a discharge box connected to the end of the screen box away from the feed plate, a discharge box with an open side wall and a plurality of discharge plates installed from top to bottom inside the discharge box, the number of which is equal to the number of the screen roller groups and their positions are one-to-one.

[0007] According to the technical solution provided in the embodiments of this application, a connecting bracket for installation on an external radish harvester is fixedly installed on the side wall of the bottom plate away from the discharge box, and the end of the spring away from the side plate is fixedly connected to the corresponding outer side wall of the sieve box.

[0008] In this setup, the device is fixed to the radish harvester via a connecting bracket to perform vibrating soil screening.

[0009] According to the technical solution provided in the embodiments of this application, at least one telescopic rod is fixedly installed between the side plate on the same side and the outer wall of the sieve box, and the vertical rod and the elliptical block are always in contact;

[0010] According to the technical solution provided in the embodiments of this application, when the minor axis of the elliptical block abuts against the vertical rod, the spring and telescopic rod on the same side are compressed to their shortest state; when the major axis of the elliptical block abuts against the vertical rod, the spring on the same side is in its natural state, and the telescopic rod on the same side is extended to its longest state.

[0011] In both of these settings, the eccentric impact of the elliptical block and the vertical rod drives the screen box to vibrate at high frequency.

[0012] According to the technical solution provided in the embodiments of this application, the screen roller group includes a plurality of screen rollers that are linearly and equidistantly distributed. A roller core is coaxially fixedly inserted into the screen roller. The higher end of the roller core is rotatably inserted into the inner side wall of the screen box near the feed plate, and the lower end of the roller core is rotatably inserted into the discharge plate at the corresponding position.

[0013] According to the technical solution provided in the embodiments of this application, the diameter of the screen rollers in the plurality of screen roller groups decreases sequentially from top to bottom, and the distance between two adjacent screen rollers in the plurality of screen roller groups decreases sequentially from top to bottom;

[0014] In both of these settings, multiple sets of sieve rollers are used to sort radishes by size.

[0015] According to the technical solution provided in the embodiments of this application, the top surface of the plate segment of the discharge plate in the discharge box is lower than the top surface of the roller end of the corresponding screen roller group that is close to the discharge plate, and the plate end of the discharge plate extending out of the discharge box is inclined downward, and the lower ends of the plurality of discharge plates are respectively fixedly connected with guide grooves in different directions.

[0016] In this setup, the discharge plate, which is lower than the top surface of the corresponding screen roller group, facilitates the radish to slide in and be collected by sliding out through the inclined end.

[0017] According to the technical solution provided in the embodiments of this application, two parallel baffles are fixedly connected to the two corresponding side walls of the portion of the discharge plate extending out of the discharge box, and a soil collection drawer is slidably inserted into the side wall of the discharge box away from the screen box. The soil collection drawer extends into the screen box and its size is larger than the cross-sectional size of each set of screen rollers.

[0018] In this setup, the baffle prevents the radish from sliding out and falling to the ground, and the soil collection drawer facilitates the unified collection and processing of the sieved soil.

[0019] In summary, this technical solution specifically discloses a vibrating screen-type radish harvesting and sorting device, which includes a spring, a screen box, a screen roller group, and screen rollers. The rolling conveying method of the spring and the screen roller group avoids violent collisions between the radish and the rigid components, effectively protecting the surface of the radish. The screen rollers, with their diameter decreasing from top to bottom and the adjacent spacing decreasing, can accurately match radishes of different sizes, realizing graded sorting.

[0033] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Please see Figures 1-6 A vibrating screen for harvesting and sorting radishes includes a base 1, which includes a base plate 11. Two parallel side plates 12 are vertically mounted on the top surface of the base plate 11. Several springs 121 arranged in a matrix are fixedly mounted on the opposing side of the two side plates 12. Vertical rods 123 are also fixedly mounted on the opposing side of the two side plates 12. A screen box 2 with the same top opening is connected between the two side plates 12. Vibrating motors 21 are fixedly mounted on the outer side walls of the screen box 2 near the two side plates 12. An elliptical block 22 is coaxially connected to the top surface of the output shaft of the vibrating motor 21. A feed plate 23 is fixedly mounted on the top surface of one side wall of the screen box 2. Several inclined screen roller groups 3 are installed from top to bottom inside the screen box 2. The end of the screen box 2 away from the feed plate 23 is connected to a discharge box 4. One side wall of the discharge box 4 is open and several discharge plates 41, which are equal in number and corresponding in position to the screen roller groups 3, are installed from top to bottom inside the discharge box 4.

[0036] In this embodiment, as Figure 2As shown, a connecting bracket 13 for mounting on an external radish harvester is fixedly installed on the side wall of the base plate 11 away from the discharge box 4. The device is installed on the radish harvester through the connecting bracket 13 for operation. The end of the spring 121 away from the side plate 12 is fixedly connected to the corresponding outer side wall of the sieve box 2. The spring 121 elastically connects the base 1 and the sieve box 2, making it convenient to drive the sieve box 2 to shake for soil screening.

[0037] Furthermore, such as Figure 2 As shown, at least one telescopic rod 122 is fixedly installed between the side plate 12 on the same side and the outer wall of the screen box 2. It plays a horizontal limiting role during the vibration of the screen box 2. The vertical rod 123 and the elliptical block 22 are always in contact, which can ensure that the screen box can vibrate continuously when the elliptical block 22 rotates.

[0038] Furthermore, such as Figure 3 and Figure 4 As shown, when the short axis of the elliptical block 22 abuts against the vertical rod 123, the spring 121 and the telescopic rod 122 on the same side are compressed to their shortest state; when the long axis of the elliptical block 22 abuts against the vertical rod 123, the spring 121 on the same side is in its natural state, and the telescopic rod 122 on the same side is extended to its longest state. The vibration motor 21 drives the elliptical block 22 to rotate, and the eccentric structure of the elliptical block 22 continuously impacts the vertical rod 123. Combined with the elastic restoring force of the spring 121, it drives the sieve box 2 to generate high-frequency vibration, thereby achieving the separation of soil and radish.

[0039] It is important to note that, such as Figure 5 and Figure 6 As shown, the sieve roller group 3 includes several sieve rollers 31 that are linearly and equidistantly distributed. A roller core 32 is coaxially fixedly inserted into the sieve roller 31. The higher end of the roller core 32 is rotatably inserted into the inner side wall of the sieve box 2 near the feed plate 23, and the lower end of the roller core 32 is rotatably inserted into the discharge plate 41 at the corresponding position. The sieve roller 31 can rotate with the radish, reducing frictional damage to the radish during the falling process.

[0040] In this embodiment, as Figure 6 As shown, the diameter of the screen rollers 31 in the several screen roller groups 3 decreases from top to bottom, and the distance between two adjacent screen rollers 31 in the several screen roller groups 3 decreases from top to bottom. The upper screen rollers 31 have a large spacing, allowing small-sized radishes to fall to the lower layer, while large-sized radishes remain in the upper layer and are discharged through the corresponding discharge plate 41. The lower screen rollers 31 have a small spacing to separate smaller-sized radishes, ultimately achieving grading and sorting from large to small.

[0041] Furthermore, such as Figure 3As shown, the top surface of the discharge plate 41 inside the discharge box 4 is lower than the top surface of the roller end of the corresponding sieve roller group 31 near the discharge plate 41, which facilitates the radish to slide into the discharge box 4. The end of the discharge plate 41 extending out of the discharge box 4 is inclined downward. Several discharge plates 41 are fixedly connected to guide troughs 43 with different directions at their lower ends. The radish is guided into the guide troughs 43 with different directions by gravity for sorting and output collection, preventing the radish from being mixed again.

[0042] It is worth mentioning that, such as Figure 5 As shown, several discharge plates 41 extend out of the discharge box 4. Two parallel baffles 42 are fixedly connected to the two corresponding side walls to prevent the radishes from rolling to the bottom and causing damage. A soil collection drawer 5 is slidably inserted into the side wall of the discharge box 4 away from the sieve box 2. The soil collection drawer 5 extends into the sieve box 2 and its size is larger than the cross-sectional size of each set of sieve rollers 31. It can collect the soil that leaks from the gaps between the sieve rollers 31, realize the separation of soil and vegetables, and facilitate subsequent processing.

[0043] Finally, it should be noted that the vibration motor 21 involved in this utility model is a general standard part or a component known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0044] Working principle: In this embodiment, the vibrating screen soil-type radish harvesting and sorting device is used so that the radishes enter the screen box 2 through the feed plate 23. The vibrating motors 21 on both sides of the screen box 2 drive the elliptical blocks 22 to rotate. Because the side wall of the elliptical blocks 22 abuts against the vertical rod 123, the screen box 2 vibrates under the cooperation of the spring 121 and the telescopic rod 122, realizing the function of vibrating soil screening. The screen roller group 3 is arranged from top to bottom in the screen box 2. The diameter of the screen roller 31 and the distance between adjacent screen rollers 31 decrease from top to bottom. During the rotation of the screen roller 31, the radishes pass through the gaps of different screen roller groups 3 according to their size and are sorted and output through the corresponding discharge plate 41. The discharge plate 41 extends into the discharge box 4 and tilts downward to facilitate the radishes to slide down. The baffle 42 prevents the radishes from rolling down. The guide troughs 43 with different directions prevent the sorted radishes from mixing together again. The soil collection drawer 5 can collect the soil that falls during the screening process.

[0045] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
