Description

Technical Field

[0001] This utility model relates to the field of agricultural product testing technology, and in particular to an agricultural product testing sample divider. Background Technology

[0002] For example, Chinese patent CN219038557U discloses an agricultural product testing and sorting device. By vibrating the screen up and down, it increases the speed of agricultural product sorting, enabling rapid sorting with high efficiency and good results. The device pushes the crops into the sorting port by the horizontal reciprocating movement of two pusher plates, preventing screen blockage, saving time and effort, and meeting the needs of large-scale sorting.

[0003] However, the above application only uses sieves to screen and sample agricultural products by particle size. However, many agricultural products have a large overall particle size but are shriveled, or even hollow inside due to insects. Therefore, it is necessary to remove these substandard agricultural products to avoid affecting the sample testing data. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an agricultural product testing and sorting device, which solves the technical problem that existing technologies cannot sort and screen out shriveled or hollow agricultural products that have been eaten by insects. This achieves the purpose of removing substandard agricultural products and avoiding affecting the sorting and testing data.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an agricultural product testing and sampling device, including a screening box installed on the sampling device, the screening box being provided with a screening mechanism for screening out substandard agricultural products, and the internal part of the sampling device being provided with a sampling mechanism for sorting agricultural products by size.

[0006] The screening mechanism includes a rotating shaft rotatably connected inside the screening box, on which clappers are installed in a ring at equal intervals. A drive motor for driving the rotating shaft to rotate is installed on the back of the screening box. The screening box is equipped with a conveying mechanism for conveying the agricultural products after washing and screening.

[0007] Preferably, the conveying mechanism includes a feeding tank that is inclinedly installed inside the screening box, and the other end of the feeding tank extends to the outside of the screening box. A rotating shaft is rotatably connected inside the feeding tank, and a conveying auger is installed on the rotating shaft. A feeding pipe extending into the sampler is installed at the bottom right side of the feeding tank, and a feeding motor that drives the rotating shaft to rotate is installed on the right side of the feeding tank.

[0008] Preferably, the left side of the feeding tank located inside the screening box is in a semi-open state, and the conveying auger is uniformly provided with filter holes.

[0009] Preferably, the sample separation mechanism includes two vertically equidistant sample separation sieves arranged in the upper middle part of the sampler's interior. A guide sieve is installed in the lower part of the sampler's interior. Both the sample separation sieve and the guide sieve are installed at an incline inside the sampler, and guide holes with progressively smaller inner diameters are uniformly opened through them. A discharge pipe is provided on one side of the sampler, corresponding to the lowest incline of the sample separation sieve and the guide sieve. A vibration component is provided inside the sampler to cause the sample separation sieve to intermittently oscillate along an up-down trajectory.

[0010] Preferably, the vibration assembly includes vibration springs installed at the four corners of the bottom of the sample sieve plate, an mounting plate for installing the vibration springs is provided on the inner wall of the sampler, a shaft is rotatably connected inside the slot opened on the back of the sampler, and a protrusion that acts on the lower surface of the sample sieve plate to make it swing up and down is fixedly connected to its front end, and a rotary motor for driving the shaft to rotate is installed on the sampler.

[0011] Preferably, each of the two shafts is equipped with a pulley, and the two shafts are connected by a drive belt that is rotatably connected to the pulleys.

[0012] Preferably, the bottom left and right sides of the sampler are provided with material discharge ramps, the back of the sampler is equipped with a waste discharge pipe corresponding to the lowest end of the material discharge ramps, and the sampler is equipped with an observation window.

[0013] By employing the above technical solution, this utility model provides an agricultural product testing and sampling device, which has at least the following beneficial effects:

[0014] 1. This utility model uses a rotating shovel to press agricultural products into the water inside the screening box. Plump agricultural products naturally sink to the bottom of the screening box, while shriveled and hollow agricultural products float on the surface, thereby removing shriveled and hollow agricultural products.

[0015] 2. This utility model uses the combination of two sample-separating sieve plates and a guide sieve plate to perform multi-level sample screening of agricultural products with different particle sizes, which facilitates subsequent testing.

[0016] 3. This utility model uses a rotary motor to drive the protrusion to rotate, thereby impacting the sample sieve plate, which in turn causes the sample sieve plate to vibrate up and down on the vibrating spring. This prevents agricultural products from accumulating on the sample sieve plate and clogging the guide holes, thus improving the screening efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] To address the current problem of being unable to properly sample and screen out shriveled or insect-eaten hollow agricultural products, this embodiment provides an agricultural product testing and sorting device. Please refer to... Figures 1-5This embodiment provides an agricultural product testing and sorting device that can remove substandard agricultural products to avoid affecting the sampling and testing data. The device includes a screening box 2 installed on a sorting unit 1, with a screening mechanism 3 for screening substandard agricultural products on the screening box 2. Inside the sorting unit 1 is a sorting mechanism 5 for sorting agricultural products by size. The screening mechanism 3 removes shriveled or hollow agricultural products. The screened agricultural products are then transported by a conveying mechanism 4 within the screening mechanism 3 to the sorting mechanism 5 for further screening and sorting, facilitating subsequent testing.

[0028] Since existing technology cannot separate and screen out shriveled or hollow agricultural products that have been eaten by insects, this device is equipped with a screening mechanism 3. The screening mechanism 3 includes a rotating shaft 301 rotatably connected inside the screening box 2. Plates 302 are installed in a ring at equal intervals on the rotating shaft 301. A drive motor 303 is installed on the back of the screening box 2 to drive the rotating shaft 301 to rotate. The screening box 2 is equipped with a conveying mechanism 4 for conveying the agricultural products after washing and screening. The agricultural products are poured into the screening box 2, and then the drive motor 303 is started to drive the rotating shaft 301 to rotate, thereby driving the plate 302 on the rotating shaft 301 to rotate and press the agricultural products into the water inside the screening box 2. The plump agricultural products naturally sink to the bottom of the screening box 2, while the shriveled and hollow agricultural products float on the surface of the water, thereby screening out the shriveled and hollow agricultural products.

[0029] After the shriveled and hollow agricultural products are screened out, the plump agricultural products need to be introduced into the sampler 1 for sorting. Therefore, the device is also equipped with a conveying mechanism 4. The conveying mechanism 4 includes a feeding tank 401 that is installed at an incline in the screening box 2, and the other end of the feeding tank 401 extends to the outside of the screening box 2. A rotating shaft 402 is rotatably connected inside the feeding tank 401. A conveying auger 403 is installed on the rotating shaft 402. A feeding pipe 404 that extends into the sampler 1 is installed on the bottom right side of the feeding tank 401. A feeding motor 405 that drives the rotating shaft 402 to rotate is installed on the right side of the feeding tank 401.

[0030] The left side of the feeding tank 401, located inside the screening box 2, is in a semi-open state. The conveying auger 403 has evenly spaced filter holes. When the feeding motor 405 is started, it drives the rotating shaft 402 to rotate, thereby driving the conveying auger 403 on the rotating shaft 402 to rotate. The agricultural products that have settled at the bottom of the screening box 2 are conveyed to the top of the feeding tank 401 and introduced into the sampler 1 through the feeding pipe 404 for sampling and screening. The filter holes on the conveying auger 403 filter out water, preventing a large amount of water from being introduced into the sampler 1.

[0031] For testing purposes, agricultural products of different particle sizes need to be sorted before testing. Therefore, the device is also equipped with a sampling mechanism 5. The sampling mechanism 5 includes two sampling screen plates 501 that are vertically and equidistantly arranged in the upper part of the sampler 1. A guide screen plate 502 is installed at the lower part of the sampler 1. Both the sampling screen plates 501 and the guide screen plate 502 are installed at an incline inside the sampler 1, and guide holes with progressively smaller inner diameters are evenly distributed through them. A discharge pipe 503 is provided on one side of the sampler 1, corresponding to the lowest incline of the sampling screen plates 501 and the guide screen plates 502. A vibration component 504 is provided inside the sampler 1 to make the sampling screen plates 501 intermittently swing along an up-down trajectory. Agricultural products introduced into the sampler 1 through pipe 404 fall onto the sampling sieve plate 501. Agricultural products with larger particle diameters remain on the surface of the top sampling sieve plate 501, while agricultural products with smaller diameters fall through the largest diameter guide hole on the top sampling sieve plate 501 onto the middle sampling sieve plate 501, and agricultural products with even smaller diameters fall through the guide hole on the middle sampling sieve plate 501 onto the guide sieve plate 502. This completes the multi-stage screening of agricultural products by size. Since the sampling sieve plate 501 and the guide sieve plate 502 are both installed at an angle inside the sampler 1, the agricultural products roll to the left side of the sampling sieve plate 501 and the guide sieve plate 502 under the action of gravity and are discharged through the discharge pipe 503.

[0032] The bottom left and right sides of the sampler 1 are provided with material discharge ramps 601. The back of the sampler 1 is equipped with a waste discharge pipe 602 corresponding to the lowest end of the material discharge ramp 601. The sampler 1 is equipped with an observation window 603. Small agricultural products fall through the guide hole opened on the guide screen plate 502 and onto the material discharge ramp 601, and slide down to the waste discharge pipe 602 for discharge. The sorting situation inside the sampler 1 can be observed in real time through the observation window 603.

[0033] Example 2

[0034] Based on Example 1, such as Figures 1-5As shown, since relying on gravity to allow agricultural products to roll naturally is inefficient and may result in product accumulation and failure to fall, the device also includes a vibration assembly 504. The vibration assembly 504 includes vibration springs 5041 installed at the four corners of the bottom of the sampling sieve plate 501. An mounting plate 5042 for installing the vibration springs 5041 is provided on the inner wall of the sampler 1. A shaft 5043 is rotatably connected inside a slot on the back of the sampler 1, and its front end is fixedly connected to a convex force that acts on the lower surface of the sampling sieve plate 501, causing it to swing up and down. Block 5044, a rotary motor 5045 is installed on the sampler 1 to drive the shaft 5043 to rotate. When the rotary motor 5045 is started, the shaft 5043 is driven to rotate, which in turn drives the protrusion 5044 at its front end to rotate and strike the sample sieve plate 501. This causes the sample sieve plate 501 to vibrate up and down on the stretching vibration spring 5041, which improves the sorting efficiency. Moreover, because the protrusion 5044 is located on the bottom right side of the sample sieve plate 501, when the sample sieve plate 501 is driven to vibrate, it is higher on the right and lower on the left, which makes it easier for agricultural products to be discharged.

[0035] Both shafts 5043 are equipped with pulleys 505. The two shafts 5043 are connected by a drive belt 506 that is rotatably connected to the pulleys 505. The drive belt 506 rotates between the two pulleys 505, thereby driving the two shafts 5043 to rotate synchronously, thus vibrating the two sample sieve plates 501 synchronously, which improves the sorting efficiency.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
