Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole of the utility model or as the limitation or restriction of the technical scheme of the utility model.
[0031] Embodiment 1
[0032] Please refer to Figure 1 and Figure 2 The embodiment introduces a wheat flour impurity removing device for agricultural and sideline product processing, mainly comprising a machine shell 1, an elastic support 2, a filtering mechanism 3 and a driving part 4. The machine shell 1 comprises a machine body 11 and a machine cover 12, the machine body 11 is provided with an opening at the top, the machine cover 12 is arranged on the top of the machine body 11 and detachably connected to the machine body 11 through buckles, clamps and the like, a feeding port is arranged on the machine cover 12, and a hole capable of allowing the top of the filtering mechanism 3 to pass through is arranged at the center of the machine cover 12, and the driving part 4 is arranged close to the hole and used for pushing the filtering mechanism 3 downward.
[0033] A first opening for discharging impurities and a second opening for matching the filtering mechanism 3 are arranged on the middle section of the machine body 11. The first opening and the second opening are arranged staggered, and the height of the first opening is higher than that of the second opening.
[0034] As shown in Figure 3 , the elastic support 2 mainly comprises a fixed ring 21, a movable ring 22 and a spring 23. The outer diameter of the fixed ring 21 is consistent with the inner diameter of the machine body 11, the fixed ring 21 is installed at the middle section of the inner wall of the machine body 11, the outer diameter of the movable ring 22 matches the inner diameter of the fixed ring 21, the movable ring 22 is sleeved in the fixed ring 21, and since the axial length of the movable ring 22 is greater than that of the fixed ring 21, the movable ring 22 moves longitudinally in the fixed ring 21. The top of the movable ring 22 is located above the fixed ring 21 and extends horizontally and contacts the inner wall of the machine body 11, the extension part not only can stabilize the longitudinal movement of the movable ring 22, but also can shield the gap between the fixed ring 21, the spring 23 is arranged in the gap between the two, and used for pushing the movable ring 22 upward. And the spring 23 is shielded by the movable ring 22 and basically does not contact the wheat flour.
[0035] As shown in Figure 4 , the filtering mechanism 3 mainly comprises a rotating part 31, a filter screen 32, a support rod 33 and a fan-shaped baffle 34. The filter screen 32 is placed on the top of the movable ring 22, the outer diameter of the filter screen 32 is greater than that of the movable ring 22 and smaller than that of the fixed ring 21, so that the filter screen 32 is located on the top of the movable ring 22 and has a gap with the machine body 11. The support rod 33 is installed at the center of the filter screen 32, and the top end of the support rod 33 penetrates the hole at the center of the machine cover 12 and is located above the machine cover 12.
[0036] The fan-shaped baffle 34 is movably connected with the outer surface of the supporting rod 33, that is, the fan-shaped baffle 34 has a cylindrical sleeve at the center, which is sleeved on the outer surface of the supporting rod 33, and the two can be rotatably connected through a bearing, or the outer side of the supporting rod 33 and the inner side of the cylindrical sleeve have a protrusion and an annular groove respectively, so as to realize the rotatable connection of the two. The fan-shaped baffle 34 is located above the filter screen 32, one of the radius edges extends downward and contacts the top of the filter screen 32, and is close to the opening; the other radius edge extends downward and maintains a fixed distance from the top of the filter screen 32, and the rotating direction of the filter screen 32 inside the machine body 11 is from the side edge extending position of the fan-shaped baffle 34 not contacting the filter screen 32 to the side edge extending position contacting the filter screen 32. If there is impurity on the top of the filter screen 32, as the filter screen 32 rotates, the impurity enters the lower side of the fan-shaped baffle 34 and is intercepted by the side edge extending position of the fan-shaped baffle 34 contacting the filter screen 32.
[0037] The filter screen 32 can be rotated through the rotating part 31. The rotating part 31 includes a gear 311 and a tooth ring 312, the inner diameter of the tooth ring 312 is consistent with the outer diameter of the filter screen 32, the tooth ring 312 is fixed on the outer periphery of the filter screen 32, the gear 311 is engaged with the tooth ring 312, the opening two of the machine body 11 has a corresponding protrusion for rotatably connecting the gear 311, and the gear 311 can drive the tooth ring 312 to rotate, thereby driving the filter screen 32 to rotate. Since the fan-shaped baffle 34 is movably connected with the supporting rod 33, whether the supporting rod 33 is fixedly connected with the filter screen 32 or movably connected with the filter screen 32, the rotation of the filter screen 32 does not affect the fan-shaped baffle 34. It is preferred that the filter screen 32 is also movably connected with the supporting rod 33, so as to keep the supporting rod 33 relatively fixed. In order to further limit the rotation of the fan-shaped baffle 34, a limiting block can be arranged on the inner wall of the machine body 11 to limit the rotation of the fan-shaped baffle 34 with the filter screen 32, so as to keep the fan-shaped baffle 34 always located at the opening one.
[0038] In order to avoid the wheat flour entering the gap between the tooth ring 312 and the gear 311, the top of the tooth ring 312 is fixedly connected with an annular baffle 35 for shielding the pattern of the tooth ring 312, and the outer periphery of the annular baffle 35 contacts the inner wall of the machine body 11. Through the shielding of the annular baffle 35, the wheat flour can be intercepted without contacting the tooth ring 312 or the gear 311. It should be emphasized that the height of the annular baffle 35 is consistent with the height of the filter screen 32, and the two are arranged at the same height.
[0039] The gear 311 can be manually rotated to drive the filter screen 32 to rotate through the cooperation of the gear 311 and the gear ring 312, or a rotating structure can be used to rotate the gear 311. The rotating structure can be only a micro motor, and the output shaft is directly connected to the central shaft of the gear 311, and the gear 311 is driven to rotate by the micro motor. Or the micro motor cooperates with the driving teeth, that is, the driving teeth are engaged beside the gear 311, the driving teeth are connected with the output shaft of the micro motor, and the micro motor is installed on the outer wall of the machine body 11 to achieve the purpose of driving the filter screen 32 to rotate. It should be noted that the driving direction of the micro motor is consistent with the direction in which the filter screen 32 needs to rotate. The rotating structure is not limited to the structure described above, and other structures can also be used as long as they can drive the filter screen 32 to rotate in the specified direction through the cooperation of the gear ring 312 and the gear 311.
[0040] As shown in Figure 5 The driving member 4 is mainly composed of a motor and a rotating disc. The motor is installed on the top of the cover 12, and the motor can be installed on the cover 12 through a motor support, so that the output shaft of the motor faces downward and maintains a fixed distance with the cover 12. The output shaft of the motor is connected with the rotating disc, the bottom of the rotating disc is inclined, and the top of the supporting rod 33 is eccentrically arranged. The reciprocating movement of the supporting rod 33 can be achieved through the rotation of the rotating disc and the cooperation of the spring 23. That is, when the protruding part of the bottom of the rotating disc is in contact with the supporting rod 33, the supporting rod 33 is pushed downward, and the spring 23 is compressed. When the non-protruding part (thinner part) of the bottom of the rotating disc is in contact with the top of the supporting rod 33, the supporting rod 33 moves upward under the pushing of the spring 23. Therefore, the longitudinal reciprocating movement of the supporting rod 33 is achieved through the rotation of the rotating disc, thereby achieving the vibration of the filter screen 32.
[0041] When the wheat flour enters the machine body 11 through the feeding port, the filter screen 32 vibrates through the cooperation of the driving member 4 and the spring 23, the impurities are intercepted by the filter screen 32, and the remaining wheat flour passes through the filter screen 32 and is discharged through the discharge port. The filter screen 32 is rotated through the rotating gear 311 or the rotating structure, and the impurities on the top of the filter screen 32 are intercepted by the sector-shaped baffle 34 along with the rotation of the filter screen 32. The impurities can be discharged from the opening of the machine body 11 along with the vibration of the filter screen 32. When maintenance is needed, the cover 12 can be removed from the machine body 11, and the filter screen 32 and other structures can be taken out of the machine body 11 through the supporting rod 33, thereby facilitating cleaning and maintenance operations.
[0042] The embodiment can remove impurities from the ground wheat flour through the cooperation of the elastic supporting member 2 and the filtering mechanism 3. The filtering mechanism 3 is placed on the top of the elastic supporting member 2 and is easy to be separated from the machine shell 1, thereby facilitating the corresponding cleaning operation of the filtering mechanism 3. The multiple mechanisms are separately arranged, and the subsequent maintenance operation is easy.
[0043] Embodiment 2
[0044] This embodiment describes a wheat flour impurity removal device for agricultural and sideline product processing. Its structure is essentially the same as the wheat flour impurity removal device for agricultural and sideline product processing described in Example 1. The difference lies in the use of a telescopic cylinder as the driving element 4. The top of the cover 12 is connected to the fixed end of the telescopic cylinder, and the movable end of the telescopic cylinder faces and contacts the top of the support rod 33. The telescopic cylinder pushes down the support rod 33, cooperating with the spring 23 to achieve longitudinal reciprocating movement of the support rod 33.
[0045] This embodiment has the same beneficial effects as embodiment 1.
[0046] Example 3
[0047] like Figure 6 As shown, this embodiment introduces a wheat flour impurity removal device for agricultural and sideline product processing. Its structure is basically the same as the wheat flour impurity removal device for agricultural and sideline product processing described in Example 1. The difference is that this embodiment is provided with a negative pressure structure at an opening of the body 11 to suck impurities intercepted by the fan-shaped baffle 34 out of the interior of the body 11 through the opening.
[0048] The negative pressure structure can be primarily composed of a negative pressure pump and an impurity storage box. The impurity storage box is placed beside the body 11 and is connected to an opening in the body 11 via a pipe. The negative pressure pump is installed outside the impurity storage box, with its input end connected to the impurity storage box. To prevent impurities from entering the negative pressure pump input end, an interception net can be installed at the connection between the negative pressure pump input end and the impurity storage box.
[0049] This embodiment can automatically suck the impurities intercepted by the sector-shaped baffle 34 into the impurity storage box through the negative pressure structure, thereby preventing the impurities from accumulating at the sector-shaped baffle 34.
[0050] Example 4
[0051] This embodiment introduces a wheat flour impurity removal device for processing agricultural and sideline products, which has a structure substantially identical to that of the wheat flour impurity removal device for processing agricultural and sideline products described in Example 1. The difference is that this embodiment is provided with a scraper at one of the openings in the body 11 to scrape impurities intercepted by the fan-shaped baffle 34 away from the interior of the body 11 along the direction of the opening. The scraper passes through the opening 1 and is located between the fan-shaped baffle 34 and the filter 32. The scraper has a rod-shaped handle, the end of which is located outside the body 11. A retractable rod-shaped handle can be used. When a large amount of impurities accumulate on the fan-shaped baffle 34 and are not discharged from the opening 1, the scraper can be pulled outward to discharge the impurities located on the fan-shaped baffle 34 from the opening 1, thereby preventing the accumulation of impurities on the fan-shaped baffle 34.
[0052] The technical scope of the utility model is not only limited to the content in the above description, and the person skilled in the art can make various deformations and modifications to the above embodiment without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
