Description
Technical Field
[0001] The invention belongs to the technical field of agricultural machinery, and in particular is an agricultural product filtering device which is convenient for filtering different agricultural products. Background Art
[0002] Agricultural products are primary products derived from agriculture, that is, plants, animals, microorganisms and their products obtained in agricultural activities. Among them, primary products refer to unprocessed or only preliminarily processed agricultural, forestry, animal husbandry, fishery, mining and other products produced by primary industries; "agricultural activities" include both traditional agricultural activities such as planting, breeding, picking, fishing, and modern agricultural activities such as facility agriculture and bioengineering; plants, animals, microorganisms and their products are a broad concept of agricultural products, including unprocessed products directly obtained from agricultural activities and preliminarily processed products such as sorting, peeling, shelling, crushing, cleaning, cutting, freezing, waxing, grading, packaging, etc., but without changing their basic natural properties and chemical properties.
[0003] The agricultural product filtering device is a device used to filter agricultural products, which is convenient for separating impurities mixed in agricultural products from agricultural products, thereby improving the overall quality of agricultural products, or separating mixed agricultural products, thereby facilitating the later processing of agricultural products.
[0004] Most of the agricultural product filtering devices currently available can only filter and remove impurities from one agricultural product, or can only filter a single property of agricultural products. If only one property is filtered and only one agricultural product is screened, the filtering efficiency of the device will be reduced. Therefore, it is necessary to propose an agricultural product filtering device with high filtering efficiency. Summary of the invention
[0005] In order to solve the above-mentioned problem of low screening and filtering efficiency, the purpose of the present invention is to provide an agricultural product filtering device which is convenient for filtering different agricultural products, and filters different agricultural products through a density sorting system and a quality sorting system to improve the filtering efficiency of the device.
[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an agricultural product filtering device for filtering different agricultural products, comprising a chassis, the chassis including a density sorting system and a quality sorting system from top to bottom, a first feed inlet is opened at the top of the chassis near the side wall, and a plurality of heavy material outlets are opened at the bottom of the chassis;
[0007] The density sorting system includes a water reservoir, which is connected to the bottom of the first feed inlet, a material discharge slope with one side of the first feed inlet as the slope top is provided at the bottom of the water reservoir, a circulating water system is provided at the bottom of the material discharge slope, a water inlet pipe is connected to the side wall of the chassis near the top of the material discharge slope, and a floating material processing system is provided on the other side of the water reservoir;
[0008] A water baffle is provided at the connection between the quality sorting system and the water reservoir, and a traction rod is fixedly connected to the top of the water baffle. The quality sorting system includes a second feed port and a spiral groove. The second feed port is located on the other side of the water baffle, and the spiral groove is connected below the second feed port.
[0009] The principle of the basic solution is: first, different agricultural products are put into the chassis through the feed port, and water is injected into the water tank inside the chassis through the water inlet pipe. At this time, the water baffle is in a closed state. When the injection level reaches and exceeds the height of the floating material processing system, the circulating water system is started. Some agricultural products will float on the water surface because their density is smaller than that of water, and flow into the floating material processing system through the water flow provided by the circulating water system. Some agricultural products will sink to the bottom of the water and accumulate along the slope because their density is larger than that of water, and the agricultural products with low density are sorted out through the floating material outlet.
[0010] After the density sorting is carried out for a period of time, the traction rod on the water baffle will pull the water baffle up, and the agricultural products with high density will enter the quality sorting system and enter the spiral groove through the second feed port. Since the spiral groove is designed in a spiral falling shape and the quality of different agricultural products is different, the agricultural products with high quality will roll against the inner circle of the spiral tube due to the centrifugal force, and the products with small quality will roll on the outer circle, so as to sort the quality of different agricultural products.
[0011] The beneficial effects of the basic scheme are: 1. Compared with the existing agricultural product filtering device, the present invention utilizes a density sorting system and a quality sorting system to sort different agricultural products twice, thereby improving the filtering efficiency to a certain extent and reducing the tedious problem of manual secondary screening of filtered agricultural products.
[0012] 2. Some agricultural products have impurities, and most impurities, such as rice husks and wheat ears, have a lower density than water. Therefore, the density sorting system can also separate impurities in agricultural products, reducing the tedious operation of subsequent impurity removal of agricultural products after filtration.
[0013] 3. When agricultural products with high density enter the quality sorting system, if the same agricultural product appears at different quality outlets, it can help farmers check whether there are bad or inferior fruits, thereby reducing the tedious problem of manual screening of bad or inferior fruits after filtering.
[0014] Furthermore, the floating material processing system comprises a filter residue ramp, which is fixedly connected to the inner wall of the chassis, and a first filter screen is arranged on the surface of the filter residue ramp, and the first filter screen is detachably connected to the chassis.
[0015] The beneficial effect of the basic solution is: when agricultural products with lower density enter the filter residue ramp, the water flow providing the driving force will pass through the filter residue ramp and the first filter net for filtering, and the impurities with lower density will be screened out and remain on the first filter net. Since the first filter net is detachably connected to the chassis wall, the first filter net can be subsequently disassembled for cleaning, thereby achieving the effect of filtering impurities in agricultural products with lower density.
[0016] Furthermore, a floating material outlet is connected to the connection between the bottom of the filter residue ramp and the inner wall of the chassis, and a water channel is penetrated and connected to the filter residue ramp.
[0017] The beneficial effect of the basic scheme is that the water flow with a horizontal plane higher than the filter residue ramp will drive the agricultural products with lower density into the filter residue ramp, and the water flow will flow through the first filter net to the waterway and down, reducing the problem of floating material outlet drainage making it difficult to collect the filtered agricultural products, thereby improving the efficiency of the device in collecting agricultural products.
[0018] Furthermore, a sliding block is provided on one side of the water retaining plate close to the outer wall of the filter residue ramp, and a sliding groove corresponding to the sliding block on the water retaining plate is provided on one side of the filter residue ramp close to the water retaining plate.
[0019] The beneficial effect of the basic scheme is: when the density sorting system is basically completed, the traction rod will simultaneously drive the water baffle to rise, and the slider on the water baffle will slide up through the slide groove corresponding to the outer wall of the filter channel. Since the water baffle is affected by water pressure in the water, the design of the slider and the slide groove can facilitate the rising of the water baffle, save time and facilitate operation, thereby improving the filtration efficiency of the device.
[0020] Furthermore, the circulating water system includes a water filtering ramp, which is located at the connection between the water baffle and the second feed port. A second filter screen is provided on the surface of the water filtering ramp, and the second filter screen is located directly below the water channel. A circulating water reservoir is provided at the lower part of the water filtering ramp. A circulating water inlet pipe is connected to one side of the circulating water reservoir, and a water pump is connected to the other end of the circulating water inlet pipe. A circulating water outlet pipe is connected to the other end of the water pump, and the other end of the circulating water outlet pipe is connected to the top of the discharge slope.
[0021] The beneficial effect of the basic scheme is that the water falling from the waterway will be filtered again through the second filter net, and then fall into the circulating water reservoir. At this time, the water pump is started to extract the water in the circulating water reservoir, and the water flows through the circulating water inlet pipe and the circulating water outlet pipe and flows out from the top of the material discharge slope, so that the clean water in the water reservoir becomes moving water, which pushes the agricultural products with lower density into the filter slope, reducing the problem of agricultural products with lower density staying in the water reservoir due to lack of power, thereby improving the efficiency of the device in filtering agricultural products. In addition, when the water baffle rises to release the water and agricultural products in the water reservoir, the water and agricultural products with higher density will flow through the water filtration ramp, and some impurities with higher density will be screened out through the second filter net. The water that plays a driving role will also pass through the second filter net and fall into the circulating water reservoir. Similarly, through the action of the water pump, the agricultural products and impurities remaining on the material discharge slope are pushed for the second time, reducing the situation of agricultural products with higher density being retained in the water reservoir.
[0022] Furthermore, the spiral groove includes a first spiral groove, a second spiral groove and a third spiral groove. The first spiral groove, the second spiral groove and the third spiral groove are fixedly connected in sequence downward along the spiral ramp. The first spiral groove is a spiral ramp with a constant groove diameter, and the groove diameters of the second spiral groove and the third spiral groove are narrow at the top of the slope and wide at the bottom of the slope.
[0023] The beneficial effects of the basic solution are: after agricultural products with higher density enter the spiral groove, they will roll along the spiral groove due to the spiral descending design of the spiral groove. Agricultural products with heavier mass will roll along the inner circle of the spiral groove, while agricultural products with lighter mass will roll on the outer circle. The design of equal groove diameter of the first spiral groove will enable multiple agricultural products to roll at the same time, thereby improving the sorting effect and reducing the problem of a single agricultural product entering the spiral groove and rolling to the bottom regardless of its mass. The design of the second and third spiral grooves, which are wide at the top and narrow at the bottom, will prevent the agricultural products in the outer circle from rolling into the next spiral groove, so that agricultural products of different paths can be distinguished, and then the quality can be filtered, thereby improving the filtering effect of agricultural products.
[0024] Furthermore, the heavy material outlet includes a first outlet, a second outlet and a third outlet. The first outlet is located at the connection between the first spiral groove and the second spiral groove, the second outlet is located at the connection between the second spiral groove and the third spiral groove, and the third outlet is located at the connection between the third spiral groove and the bottom of the chassis.
[0025] The beneficial effect of the basic scheme is: when the rolling and falling agricultural products pass through the connection between the first spiral groove and the second spiral groove, their paths will be different due to their different masses. At this time, the agricultural products with the smallest mass will fall out of the chassis through the first discharge port for collection, and the remaining agricultural products will continue to roll along the inner circle. When passing through the connection between the second spiral groove and the third spiral groove, the agricultural products with the second smallest mass will fall out of the chassis through the second discharge port for collection, and the agricultural products with the largest mass will keep rolling in the inner circle and fall into the third discharge port. The first discharge port, the second discharge port and the third discharge port are designed to distinguish between three grades of agricultural products, thereby improving the efficiency of agricultural product filtration.
[0026] Furthermore, the inner side walls of the first spiral groove, the second spiral groove and the third spiral groove are all provided with a rough sticky layer.
[0027] The beneficial effect of the basic scheme is that when agricultural products with higher density roll in the spiral groove, they will pass through the rough sticky layer provided on the inner wall of the groove. Due to the stickiness of the rough sticky layer, it will hang on the impurities attached to the surface of the agricultural products. At the same time, due to its rough design, it will also retain some impurities in the water, causing the impurities to remain in the groove, thereby improving the effect of the device in filtering impurities in agricultural products, and thereby reducing the problem of manual secondary impurity removal.
[0028] Furthermore, an elastic buffer protection layer is provided at the connection between the first discharge port and the second spiral groove and at the connection between the second discharge port and the third spiral groove.
[0029] The beneficial effect of the basic scheme is that when the agricultural products roll in the first spiral groove, the second spiral groove and the third spiral groove through the connection between the first discharge port and the second spiral groove, part of the crops will collide with the connection. The design of the elastic buffer layer reduces the problem of damage to the agricultural products due to collision, reduces the situation of manual selection of bad and inferior fruits, and thus improves the filtering efficiency of the device for crops.
[0030] Furthermore, a plurality of supporting legs are provided at the bottom of the chassis, and the plurality of supporting legs are respectively located at the four corners of the bottom outside of the chassis, and buffer pads are respectively provided at the bottoms of the plurality of supporting legs.
[0031] The beneficial effect of the basic solution is: when the water baffle rises and the dense agricultural products mixed with water fall into the spiral groove, the chassis will inevitably vibrate. The shaking of the chassis will affect the rolling of the agricultural products, and then affect the final filtering effect of the agricultural products. Therefore, the buffer pads designed at the bottom of several supporting legs effectively reduce the uneven sorting of agricultural products caused by the shaking of the chassis, and improve the filtering efficiency of the device for agricultural products.

[0038] Example 1
[0039] Basically as attached Figure 1-Figure 4 As shown: an agricultural product filtering device for filtering different agricultural products, comprising a chassis 1, the chassis 1 including a density sorting system and a quality sorting system from top to bottom, a first feed inlet 2 is provided at the top of the chassis 1 near the side wall, a plurality of heavy material outlets are provided at the bottom of the chassis 1, a plurality of supporting legs 4 are provided at the bottom of the chassis 1, the plurality of supporting legs 4 are respectively located at the four corners of the bottom of the outer side of the chassis 1, and a plurality of cushion pads are provided at the bottom of the plurality of supporting legs 4;
[0040] The density sorting system includes a water reservoir 5, which is connected to the bottom of the first feed port 2. A material discharge slope 6 with one side of the first feed port 2 as the top is provided at the bottom of the water reservoir 5. A circulating water system is provided at the bottom of the material discharge slope 6. A water inlet pipe 7 is connected to the top of the material discharge slope 6 near the side wall of the chassis 1. A floating material processing system is provided on the inner wall of the chassis 1 away from the material discharge slope 6.
[0041] The floating material processing system includes a filter residue ramp 11, which is fixedly connected to the inner wall of the chassis 1. A first filter screen 12 is provided on the surface of the filter residue ramp 11. A floating material outlet 3 is connected at the connection between the bottom of the filter residue ramp 11 and the inner wall of the chassis 1. The filter residue ramp 11 is penetrated and connected with a water passage 13. The first filter screen 12 is detachably connected to the chassis 1. A water baffle 8 is provided at the connection between the quality sorting system and the water reservoir 5. A slider 14 is provided on the side of the water baffle 8 close to the filter residue ramp 11. A chute 15 corresponding to the slider 14 is provided on the side of the filter residue ramp 11 close to the water baffle 8. A traction rod 9 is fixedly connected to the top of the water baffle 8, and the traction rod 9 passes through the top of the chassis 1.
[0042] The specific implementation process is as follows: first, different agricultural products are put into the chassis 1 through the feed port, and water is injected into the water reservoir 5 inside the chassis 1 through the water inlet pipe 7. At this time, the water baffle 8 is in a closed state. When the injection level reaches and exceeds the height of the floating material processing system, the circulating water system is started. Some agricultural products such as beans will float on the water surface because their density is smaller than that of water, and will flow into the floating material processing system through the water flow provided by the circulating water system;
[0043] The water flow with a higher level than the filter slope 11 will drive the agricultural products with lower density into the filter slope 11. The water flow providing the driving force will pass through the filter slope 11 and the first filter screen 12 for a filtration. The impurities with lower density will be screened out and stay on the first filter screen 12. The water flow will flow through the first filter screen 12 to the water channel 13 and go down. Some agricultural products such as potatoes will sink to the bottom of the water and accumulate along the slope because their density is greater than that of water.
[0044] After density sorting is carried out for a period of time, the traction rod 9 on the water baffle 8 is pulled, and the traction force will cause the slider 14 on the water baffle 8 to slide up through the corresponding slide groove 15 on one side of the filter residue ramp, so that the water baffle 8 rises, and agricultural products with high density will enter the quality sorting system. When agricultural products with high density enter the quality sorting system, it is inevitable that the chassis 1 will vibrate and shake, and the buffer pads on the supporting legs 4 will reduce the vibration generated by the chassis 1.
[0045] Example 2
[0046] The difference from the above embodiment is that the circulating water system includes a water filtering ramp 16, which is located on the side of the water retaining plate 8 away from the water reservoir. A second filter screen 17 is provided on the surface of the water filtering ramp 16, and the second filter screen 17 is located directly below the water channel 13. A circulating water reservoir 18 is provided below the water filtering ramp 16, and a circulating water inlet pipe 19 is connected to one side of the circulating water reservoir 18. The other end of the circulating water inlet pipe 19 is connected to a water pump 20, and the other end of the water pump 20 is connected to a circulating water outlet pipe 21, and the other end of the circulating water outlet pipe 21 is connected to the top of the unloading slope 6.
[0047] The specific implementation process is as follows: the water falling from the waterway 13 will fall onto the water filtering ramp 16, and after being filtered again by the second filter screen 17, it will fall into the circulating water reservoir 18. At this time, the water pump 20 is started to extract the water in the circulating water reservoir 18, and the water flows through the circulating water inlet pipe 19 and the circulating water outlet pipe 21 and flows out from the top of the unloading slope 6, so that the clean water in the water reservoir 5 becomes moving water, pushing the agricultural products with lower density into the filter residue ramp 11. In addition, when the water baffle 8 rises to release the water and agricultural products in the water reservoir 5, the water and agricultural products with higher density will flow through the water filtering ramp 16, and the second filter screen on the water filtering ramp 16 will screen out some impurities with higher density. The water that plays a driving role will also pass through the second filter screen 17 and fall into the circulating water reservoir 18. Similarly, through the action of the circulating water system, the agricultural products and impurities remaining on the unloading slope 6 are pushed for a second time.
[0048] Example 3
[0049] The difference from the above embodiment is that the mass sorting system is connected to the density sorting system through the water baffle 8, the mass sorting system includes a second feed port 10 and a spiral groove, the second feed port 10 is located on the other side of the water baffle 8, the spiral groove is connected below the second feed port 10, the spiral groove includes a first spiral groove 22, a second spiral groove 23 and a third spiral groove 24, the first spiral groove 22, the second spiral groove 23 and the third spiral groove 24 are fixedly connected and connected in sequence along the spiral ramp downward, the inner side walls of the first spiral groove 22, the second spiral groove 23 and the third spiral groove 24 are all provided with a rough viscous layer, the first spiral groove 22 is a spiral ramp with equal groove diameter, the groove diameters of the second spiral groove 23 and the third spiral groove are narrow at the top and wide at the bottom, the heavy material outlet includes a first discharge port 25, a second discharge port 26 and a third discharge port 27, the first discharge port 25 is located at the connection between the first spiral groove 22 and the second spiral groove 23, the second discharge port 26 is located at the connection between the second spiral groove 23 and the third spiral groove 24, the connection between the first discharge port 25 and the second spiral groove 23 and the connection between the second discharge port 26 and the third spiral groove 24 are both provided with an elastic buffer protective layer, and the third discharge port 27 is located at the connection between the third spiral groove 24 and the bottom of the chassis 1.
[0050] The specific implementation process is as follows: after the density sorting is carried out for a period of time, the traction rod 9 on the water baffle 8 is pulled to make the water baffle 8 rise, and the agricultural products with high density will enter the quality sorting system and enter the spiral groove through the second feed port 10. After the agricultural products with high density enter the spiral groove, they will roll along the spiral groove due to the spiral descent design of the spiral groove. When the agricultural products roll in the spiral groove, they pass through the rough sticky layer set on the inner wall of the groove, and then hang on the impurities attached to the surface of the agricultural products. The agricultural products with large mass roll along the inner circle of the spiral groove, while the agricultural products with small mass roll on the outer circle. When the rolling agricultural products fall, When passing the connection between the first spiral groove 22 and the second spiral groove 23, the paths will be different due to their different masses. At this time, the agricultural products with the smallest mass will fall out of the chassis 1 through the first discharge port 25 for collection, and the agricultural products located between the inner circle and the outer circle of the groove will collide with the elastic buffer protective layer and return to the inner circle of the spiral groove, and continue to roll with the remaining agricultural products. When passing the connection between the second spiral groove 23 and the third spiral groove 24, the agricultural products with the second smallest mass will fall out of the chassis 1 through the second discharge port 26 for collection, and finally the agricultural products with the largest mass will keep rolling in the inner circle and fall into the third discharge port 27.
