DETAILED DESCRIPTION
[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0034] Reference Figure 1-Figure 5The utility model provides a corn impurity removing and crushing device, comprising a crushing unit 1.
[0035] The crushing unit 1 may be a conventional device for crushing corn, which cooperates with the impurity removal structure to form an impurity removal and crushing device.
[0036] It also includes: a support frame 2, which is located above the crushing unit 1 and has an opening 3 at the bottom end; a vibrating screen 4, which is connected to the support frame 2 and is inclined, the high end of the vibrating screen 4 is configured as a feeding end, and the vibrating screen 4 is located above the opening 3.
[0037] Specifically, the support frame 2 is used to support the vibrating screen 4. Under the action of the vibrating screen 4, dust or impurities with a particle size smaller than the corn particles are discharged from the bottom of the vibrating screen 4 and leave the vibrating screen 4 through the opening 3, thereby achieving preliminary screening and impurity removal of the corn particles.
[0038] The first sorting plate 5 is fixed on the support frame 2 and corresponds to the lower end discharge end of the vibrating screen 4. A gap is arranged between the first sorting plate 5 and the lower end discharge end of the vibrating screen 4. The first sorting plate 5 is configured to collect stone impurities. The second sorting plate 6 is fixed on the support frame 2 and is located below the first sorting plate 5. The feed end of the second sorting plate 6 is located below the discharge end of the vibrating screen 4 and is configured to collect corn particles. The discharge end of the second sorting plate 6 is connected to the feed end of the crushing unit 1.
[0039] Specifically, the vibrating screen 4 is tilted to provide a certain speed for the corn particles, so that the corn particles and stone impurities with a volume greater than or equal to that of the corn particles leave the vibrating screen 4 at a certain speed. Since the weight of stone impurities greater than or equal to that of the corn particles is larger than that of the corn particles, the impurities move a longer distance under the action of inertia to move to the first sorting plate 5, while the corn particles move a shorter distance to move to the second sorting plate 6 to achieve corn impurity removal. The corn particles on the second sorting plate 6 move along the second sorting plate 6 to the crushing unit 1 to achieve crushing processing.
[0040] The support frame 2 is a frame structure, which should play the role of supporting the vibrating screen 4, the sorting box 7, and the feeding unit 10.
[0041] For further optimization, refer to Figure 2 , Figure 3 , and also includes a sorting box 7, which is fixed on the supporting frame 2. The first sorting plate 5 and the second sorting plate 6 are arranged in the sorting box 7 and fixed to the sorting box 7. A channel is formed between the bottom surface of the first sorting plate 5, the top surface of the second sorting plate 6, and the inner wall of the sorting box 7, and the channel is used for the movement of corn particles.
[0042] Specifically, the sorting box 7 is used to fix the first sorting plate 5 and the second sorting plate 6 .
[0043] Preferably, the top surface height of the first sorting plate 5 is lower than the top surface height of the sorting box 7, so that the side walls of the sorting box 7 are used to block both sides of the first sorting plate 5 to prevent stone impurities from escaping from the first sorting plate 5 from other directions.
[0044] For further optimization, refer to Figure 2 , Figure 3 The end of the second sorting plate 6 close to the vibrating screen 4 extends to below the discharge end of the vibrating screen 4, and baffles 8 are fixed on both side walls of the second sorting plate 6 located outside the sorting box 7.
[0045] Specifically, the second sorting plate 6 protrudes the sorting box 7 relative to the first sorting plate 5, so that the second sorting plate 6 is close to the vibrating screen 4 and receives the fallen corn particles. Baffles 8 are fixed on the two side walls of the second sorting plate 6. The baffles 8 are used to block the corn particles and prevent them from escaping from the side walls of the second sorting plate 6.
[0046] For further optimization, refer to Figure 2 , Figure 3 , and also includes a guide plate 9, which is fixed on the top surface of the first sorting plate 5. A notch is opened on the top of the side wall of the sorting box 7, and the guide plate 9 extends out of the sorting box 7 through the notch.
[0047] Specifically, the guide plate 9 is an inclined plate, which is used to guide the stone impurities collected on the first sorting plate 5 to leave the sorting box 7.
[0048] Preferably, the guide plate 9 guides the stone impurities to leave the sorting box 7 in a direction opposite to the discharging direction of the crushing unit 1 to prevent the stone impurities from affecting the discharging of the crushing unit 1 .
[0049] For further optimization, refer to Figure 1 , Figure 2 The first sorting plate 5 and the second sorting plate 6 are arranged at an angle, and the top surface of the first sorting plate 5 is located below the top surface of the vibrating screen 4 .
[0050] Specifically, since the vibrating screen 4 works by vibration, in order to ensure that the first sorting plate 5 effectively receives stone impurities, the top surface height of the first sorting plate 5 should be lower than the top surface height of the vibrating screen 4 when it is at the lowest position, and the first sorting plate 5 and the vibrating screen 4 are preferably arranged in parallel.
[0051] The first sorting plate 5 and the second sorting plate 6 are arranged at an angle to facilitate the movement of stone impurities and corn particles along the first sorting plate 5 and the second sorting plate 6 .
[0052] For further optimization, refer to Figure 1 , Figure 2 , Figure 3 , and also includes a feeding unit 10, which is fixed on the support frame 2 and whose discharge end is connected to the feed end of the vibrating screen 4.
[0053] Specifically, the feeding unit 10 is used to distribute corn particles to the vibrating screen 4 .
[0054] For further optimization, refer to Figure 5 The feeding unit 10 includes: a feeding box 1001, which is fixed on the support frame 2 and has a feeding port on the end face close to the vibrating screen 4; a rotating roller 1002, which is rotatably connected to the feeding box 1001 through a driving motor 1003, and a plurality of feeding plates 1004 are fixed circumferentially on the outer wall of the rotating roller 1002, and the space between two adjacent feeding plates 1004 is configured to store materials and transport them to the feeding port; a feeding hopper, which is fixed on the top of the feeding box 1001, and the discharging end is connected to the rotating roller 1002.
[0055] Specifically, corn particles are fed into the feed hopper and fall from the feed hopper to the space between two adjacent feed plates 1004. The driving motor 1003 drives the rotating roller 1002 to rotate, thereby driving the feed plate 1004 to move and deliver the corn particles from the feed port to the feed end of the vibrating screen 4.
[0056] Among them, since the space between two adjacent feeding plates 1004 is limited, a large number of corn particles can be placed in batches into the vibrating screen 4 to avoid accumulation of corn particles and improve the impurity removal effect.
[0057] The driving motor 1003 is fixed on the outer wall of the feeding box 1001 .
[0058] Preferably, the feed hopper is a structure with a wide feed end and a narrow discharge end.
[0059] For further optimization, refer to Figure 4 The vibrating screen 4 includes: a screen 401, which is tiltedly arranged on the support frame 2, and vertical rods 402 are passed through both sides of the screen 401, and the vertical rods 402 are fixed to the support frame 2; a compression spring 403, which is sleeved on the vertical rods 402 and has its two ends respectively fixed to the screen 401 and the support frame 2; a rotating convex head 404, which is rotatably connected to the side wall of the support frame 2 and is configured to drive the screen 401 to vibrate.
[0060] Specifically, a rotatable rotary convex head 404 is provided on the support frame 2, and the rotary convex head 404 knocks the screen 401, and the reciprocating vibration of the screen 401 is realized under the action of the compression spring 403, so as to perform preliminary impurity removal on the corn particles.
[0061] In some cases, the vibration of the vibrating screen 4 may affect the speed of corn particles leaving the vibrating screen 4, so the distance between the first sorting plate 5 and the vibrating screen 4 is set according to actual conditions.
[0062] Alternatively, an inclined smooth plate is provided at the discharge end of the vibrating screen 4, and the smooth plate is fixed to the support frame 2. The corn particles discharged from the vibrating screen 4 first fall onto the smooth plate, and then are accelerated by the smooth plate and then separated from the smooth plate, so that the corn particles are separated from stone impurities.
[0063] A driving structure is fixed on the support frame 2 , and the driving structure is used to drive the rotating convex head 404 to rotate.
[0064] Alternatively, the vibrating screen 4 adopts an existing structure and works by utilizing the reciprocating vibration generated by the excitation of the vibrator.
[0065] For further optimization, refer to Figure 2 One end of the rotating roller 1002 is fixedly connected to a first transmission roller 11, the first transmission roller 11 is located outside the feeding box 1001, and a second transmission roller 12 is connected to the rotating convex head 404. The first transmission roller 11 and the second transmission roller 12 are connected through a transmission belt 13.
[0066] Specifically, the first transmission roller 11 and the second transmission roller 12 are connected by the transmission belt 13, that is, the rotating roller 1002 is driven to rotate by the driving motor 1003, and the rotating convex head 404 is driven to rotate at the same time, so as to reduce the number of driving structures used.
[0067] Specifically, when the corn is removed from the impurities and crushed, the corn particles are fed into the lower hopper, and the rotating roller 1002 and the feeding plate 1004 cooperate to convey the corn particles in batches to the vibrating screen 4. The vibrating screen 4 works to discharge dust and impurities from the opening 3, and the corn particles move obliquely downward along the vibrating screen 4. After leaving the vibrating screen 4, the heavier impurities enter the first sorting plate 5 under the action of inertia, and the remaining corn particles enter the second sorting plate 6, and are sent to the crushing unit 1 through the second sorting plate 6 for subsequent processing and crushing.
[0068] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
