[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.
[0020] At present, when screening buckwheat, only buckwheat and sand and gravel can be screened. However, since buckwheat is inevitably broken during production and processing, in order to ensure the quality of buckwheat, the broken buckwheat needs to be screened again, which makes the operation steps more complicated, the work efficiency is low, and the work intensity of the staff is increased.
[0021] In view of this, the utility model provides a buckwheat sorting and screening device, which can perform multi-stage screening on buckwheat through the cooperation of the screening structure and the impurity removal device, and then can screen the complete and broken as well as mixed sand and gravel, and can automatically sort the buckwheat, which is convenient for the staff to subsequently process the buckwheat, improves the staff's work convenience, and also reduces the subsequent work steps and improves work efficiency.
[0022] Example 1: By Figure 1 、 2 As shown in Figure 3, a buckwheat sorting and screening device includes a base plate 1, a screening structure 2 is provided above the base plate 1, and the screening structure 2 includes: a limiting portion 21, which is provided above the base plate 1; a first screen box 22, which is provided above the limiting portion 21; a plurality of connecting rods 23, each of which is installed at the bottom of the first screen box 22; a second screen box 26, which is installed at the bottom of the plurality of connecting rods 23; a first filter screen 24, which is installed at the inner wall of the first screen box 22; a second filter screen 27, which is installed at the inner wall of the second screen box 26; a vibration motor 25, which is detachably connected to the bottom of the first screen box 22; wherein the vibration motor 25 drives the first screen box 22 and the second screen box 26 to screen the buckwheat through the first filter screen 24 and the second filter screen 27;
[0023] In the specific implementation process, it is worth noting that the mesh numbers of the first filter 24 and the second filter 27 are not limited, and they can meet the use requirements. The first filter 24 can screen complete and broken buckwheat, and the second filter 27 can screen broken and severely broken buckwheat and sand and gravel. The model of the vibration motor 25 is not limited, and it can meet the use requirements. The vibration motor 25 can ensure the continuous vibration of the first screen box 22 and the second screen box 26 by cooperating with the limit part 21;
[0024] Furthermore, the outer side of the vibration motor 25 is sleeved with a housing 251 fixedly connected to the bottom of the first screen box 22;
[0025] In the specific implementation process, it is worth noting that the design of the housing 251 can prevent the buckwheat and sand and gravel that fall from the screening from falling onto the outer wall of the vibration motor 25;
[0026] Furthermore, the limiting portion 21 includes: a plurality of vertical rods 212, all of which are installed on the top of the bottom plate 1; a plurality of sleeves 211, each movably connected to the outer walls of the plurality of vertical rods 212, and each of which is fixedly connected to the outer wall of the second screen box 26; a plurality of vertical pipes 213, each of which is movably connected to the upper part of the outer walls of the plurality of vertical rods 212, and each of which is fixedly connected to the outer wall of the first screen box 22; a plurality of springs 214, each of which is installed on the top of the plurality of vertical rods 212, and each of which is fixedly connected to the inner wall of the plurality of vertical pipes 213; wherein, when the vibration motor 25 is in operation, the shape of the spring 214 will be changed, thereby driving the first screen box 22 and the second screen box 26 to vibrate continuously through the spring 214;
[0027] In the specific implementation process, it is worth noting that the cooperation between the sleeve 211 and the vertical rod 212 can limit the second screen box 26, and the cooperation between the vertical pipe 213 and the vertical rod 212 can limit the first screen box 22. When the spring 214 is deformed, the elastic potential energy of the spring 214 will drive the first screen box 22 and the second screen box 26 to vibrate continuously.
[0028] Specifically, when using the buckwheat sorting and screening device, when screening buckwheat, the staff pours the buckwheat into the first screen box 22, and then turns on the control power of the vibration motor 25. At this time, the vibration motor 25 can drive the first screen box 22 to move. Due to the connecting rod 23, the second screen box 26 is driven to move at the same time. At the same time, the vertical pipe 213 and the sleeve 211 move on the outer wall of the vertical rod 212 at the same time, and the vertical pipe 213 will also change the shape of the spring 214. At this time, the elastic potential energy of the spring 214 can drive the first screen box 22 and the second screen box 26 to vibrate continuously, and then the first filter screen 24 and the second filter screen 27 can be used for screening and sorting.
[0029] Example 2: By Figure 1 、 2 As can be seen from Figure 4, a dust removal device 3 is provided above the first screen box 22, and the dust removal device 3 includes: a bracket 31, mounted on the top of the bottom plate 1; a top plate 32, mounted on the top of the bracket 31; a collecting box 33, mounted on the top of the top plate 32; a third filter 35, mounted on one side of the inner wall of the collecting box 33, and fixedly connected to the top of the top plate 32; a fan 34, provided on one side of the top of the top plate 32, and the output end is connected to the upper side of the collecting box 33; a collecting pipe row 36, which passes through the inner wall of the top plate 32 and extends to the upper part of the interior of the first screen box 22; wherein, the fan 34 draws out the air inside the collecting box 33, and through the negative pressure effect, the broken shells and dust inside the buckwheat can enter the interior of the collecting box 33 through the collecting pipe row 36;
[0030] In the specific implementation process, it is worth noting that the mesh number of the third filter 35 is not limited, as long as it meets the use requirements. The third filter 35 can filter and block the buckwheat hulls in the gas. The model of the fan 34 is not limited, as long as it meets the use requirements.
[0031] Furthermore, a storage device 4 is provided on the top of the bottom plate 1. The storage device 4 includes: a horizontal rail 42 installed on the top of the bottom plate 1; a drawer 41 movably connected to the outer wall of the horizontal rail 42 and movably connected to the top of the bottom plate 1; wherein the drawer 41 can collect sand and gravel and broken buckwheat;
[0032] In the specific implementation process, it is worth noting that the screened sand and gravel and overly broken buckwheat can be collected through the drawer 41;
[0033] Specifically, based on the above-mentioned embodiment 1, when removing buckwheat hulls, the staff turns on the external control power supply of the fan 34. At this time, the fan 34 can extract the air inside the collection box 33. At this time, the air pressure inside the collection box 33 is reduced. At this time, due to the negative pressure effect, the outside air can enter the interior of the collection box 33 through the collection pipe row 36. Since the buckwheat hulls are relatively light in weight, the buckwheat hulls can follow the air flow into the interior of the collection box 33, and the buckwheat hull removal work can be completed.
