It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0024] Please refer to Figure 1 and Figure 3, the present utility model provides a stirring and screening device, which includes a frame 1, a hopper 2 arranged on the frame 1, a stirring mechanism 3 arranged in the inner cavity of the hopper 2, a screening plate 4 arranged below the outlet of the hopper 2, a screening mechanism 5 connected to the screening plate 4, and a driving mechanism 6 arranged on the frame 1; a plurality of screening holes 41 are formed on the screening plate 4; the driving mechanism 6 is in transmission connection with the stirring mechanism 3 and the screening mechanism 5, and the driving mechanism 6 is used to drive the stirring mechanism 3 to stir the materials in the hopper 2, and when driving the screening mechanism 5 to operate, drive the screening plate 4 to reciprocate and screen materials with different particle sizes.

[0025] During actual use, the driving mechanism 6 is started to make the driving mechanism 6 drive the stirring mechanism 3 and the screening mechanism 5 to operate synchronously; then the materials are put into the hopper 2 from the feed inlet 211 of the hopper 2. After being stirred again by the stirring mechanism 3 and the agglomerated materials are broken up, the materials flow out from the discharge outlet 221 of the hopper 2 and fall into the screening plate 4. Under the action of the screening mechanism 5, the screening plate 4 reciprocates, that is, vibrates, so that the materials are screened through the screening holes 41 of the screening plate 4, so that the materials with a particle size smaller than the particle size of the screening holes 41 pass through the screening holes 41, while the materials with a particle size larger than the particle size of the screening holes 41 are intercepted on the screening plate 4.

[0026] In the above device, by setting a driving mechanism 6, the stirring mechanism 3 and the screening mechanism 5 can be driven to operate synchronously, so as to realize the stirring and breaking up of the materials in the hopper 2, and realize the screening of the materials by using the screening plate 4, so that the stirring and screening processes are completed in one device, which is more efficient and is beneficial to reducing the volume and manufacturing cost of the device.

[0027] Please refer to Figure 2 and Figure 3 , in some embodiments, the driving mechanism 6 includes a driving motor 61 arranged on the frame 1, a driving wheel 62 connected to the output end of the driving motor 61, a first driven wheel 63 in transmission connection with the stirring mechanism 3, a second driven wheel 64 in transmission connection with the screening mechanism 5, a first transmission belt 65 wound between the driving wheel 62 and the first driven wheel 63, and a second transmission belt 66 wound between the first driven wheel 63 and the second driven wheel 64; one side of the stirring mechanism 3 penetrates through the side wall of the hopper 2, and the first driven wheel 63 is located outside the hopper 2. Specifically, by the operation of the driving motor 61, driving the first transmission belt 65 and the second transmission belt 66 to rotate, the stirring mechanism 3 and the screening mechanism 5 can be driven to operate synchronously.

The first driven wheel 63 drives the stirring shaft 32 to rotate, so that the support plates 33 and the scraper 34 rotate synchronously. The scraper 34 can scrape off the materials on the inner wall of the hopper 2, making the mixing of the materials more uniform. Specifically, the support plates 33 and the scraper 34 are connected in a detachable manner, which is convenient for replacing the stirring mechanism 3.

[0029] Please refer to Figure 4 , in some embodiments, the screening mechanism 5 includes two second bearing seats 51 disposed on opposite side walls of the frame 1, a connecting shaft 52 rotatably connected to the second bearing seats 51, a connecting rod 54 having one end fixedly connected to the connecting shaft 52 through a connecting rod head 53 and the other end fixedly connected to the bottom of the screening plate 4. The second driven wheel 64 drives the connecting shaft 52 to rotate relative to the second bearing seats 51. When the connecting shaft 52 rotates, the connecting rod 54 is pulled through the connecting rod head 53, so that the screening plate 4 fixedly connected to the end of the connecting rod 54 vibrates back and forth, thereby accelerating the screening of the materials on the screening plate 4. Specifically, the other end of the connecting rod 54 is fixedly connected to the bottom of the screening plate 4 through the cooperation of bolts and screws.

[0030] Please refer to Figure 4 , in some embodiments, a chute 42 extending along the length direction is provided at the bottom of the screening plate 4, and a plurality of pulleys 43 cooperating with the chute 42 are installed on the frame 1. The plurality of pulleys 43 are respectively slidably disposed in the corresponding chutes 42. During the vibration of the screening plate 4, the provided chute 42 can change the relative position between the pulley 43 and the chute 42 under the sliding action of the pulley 43, and the setting of the pulley 43 makes the screening plate 4 not produce strange abnormal noises during the vibration process.

[0031] Please refer to Figure 1 and Figure 3 , in some embodiments, the hopper 2 includes an upper cover 21 and a lower cover 22, and the upper cover 21 and the lower cover 22 are detachably connected; a feed inlet 211 is provided at the top of the upper cover 21, and a discharge outlet 221 is provided at the bottom of the lower cover 22. The hopper 2 is provided with a detachable upper cover 21 and lower cover 22, which is convenient for installation and disassembly and maintenance. In this embodiment, the detachable connection between the upper cover 21 and the lower cover 22 is realized by using bolts and nuts.

[0032] Please refer to Figure 2, in some embodiments, a semi-circular sieve 7 is further disposed in the inner cavity of the lower cover body 22. The sieve 7 communicates with the inner cavities of the upper cover body 21 and the lower cover body 22, and the sieve 7 is located above the discharge port 221. Specifically, the sieve 7 is equivalent to the first screening. During the process of the stirring mechanism 3 stirring and dispersing the materials in the hopper 2, materials or impurities with larger particle sizes are intercepted in the sieve 7, and materials with particle sizes smaller than the sieve 7 pass through the sieve 7 and fall onto the screening plate 4 via the discharge port 221.

[0033] Please refer to Figure 3 , in some embodiments, the bottom of the lower cover body 22 is provided as an inclined surface, and the inclined surface is inclined in the direction of the discharge port 221. The materials passing through the sieve 7 smoothly enter the discharge port 221 under the guidance of the inclined surface, and the above setting can prevent the materials from accumulating at the bottom of the lower cover body 22.

[0034] Please refer to Figure 3 , in some embodiments, an impurity separation box 8 is further disposed on the discharge port 221. An opening is provided at the top of the impurity separation box 8, and an air blowing port 81 penetrating through both side walls of the impurity separation box 8 and communicating with the opening is further provided on the impurity separation box 8; the opening communicates with the discharge port 221; a blower 9 is further disposed on the frame 1, and the air blowing port 91 of the blower 9 is arranged towards the air blowing port 81; one of the air blowing ports 81 of the impurity separation box 8 is located outside the screening plate 4, and the other air blowing port 81 is located above the screening plate 4. During the batching or stirring process, there may be a problem of impurity mixing. Through the air blowing action of the blower 9 on the impurity separation box 8, the lighter impurities can be blown out of the impurity separation box 8 from the air blowing port 81 by the wind force. During actual use, a bag can be put on the air blowing port 81 far from the screening plate 4 or connected to a pipeline to facilitate the collection of impurities. Or in order to avoid generating dust, the blower 9 can not be started according to the actual situation, so that the impurity separation box 8 is only used as a discharge box, and the bottom of its inclined surface can be used to make the materials smoothly fall onto the screening plate 4.

[0035] Please refer to Figure 2 , in some embodiments, a first outlet 44 and a second outlet 45 are further disposed on the screening plate 4; the height of the first outlet 44 from the ground is greater than the height of the second outlet 45 from the ground; the first outlet 44 is used to output the materials on the screening plate 4, and the second outlet 45 is used to output the materials screened by the screening plate 4. Specifically, the screening plate 4 is equivalent to a filter screen. Materials with particle sizes larger than the particle size of the filter screen are intercepted on the screening plate 4 and output from the first outlet 44; while materials with particle sizes smaller than the particle size of the filter screen can smoothly pass through the screening plate 4 and be output from the second outlet 45. The above setting can achieve multi-stage filtration.
