[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0028] like Figure 1 As shown, this embodiment discloses a walnut grading and screening device, including a box body 1, a feeding channel 2 is provided at the upper end of the box body 1, and a first screening device 3, a second screening device 4 and a third screening device 5 are sequentially provided in the box body 1 from top to bottom.
[0029] like Figure 2 and Figure 3 As shown, the feed channel 2 includes a channel wall 2-1. Several rotatable feed rollers 2-2 are positioned within the upper and lower sidewalls of the channel wall 2-1. A feed port 2-5 is provided at one end of the channel wall 2-1 for feeding walnuts. A fixed shaft 2-3 is positioned along the central axis of the feed rollers 2-2, rotating in engagement with the fixed shaft 2-3. The fixed shaft 2-3 is fixedly connected to the channel wall 2-1. Several semicircular trough shells 2-4 are positioned within the upper and lower sidewalls of the channel wall 2-1, with the fixed shafts 2-3 positioned within the trough shells 2-4.
[0030] like Figure 1 and Figure 4 As shown, the first screening device 3 is located below the discharge port of the feed channel 2. The first screening device 3 includes a first screen basket 3-1, which is connected to the inner wall of the casing 1 via a first connecting spring 3-2. One end of the first screen basket 3-1 is fixedly connected to a first drainage trough 3-3. The second screening device 4 includes a second screen basket 4-1, which is connected to the inner wall of the casing 1 via a second connecting spring 4-2. One end of the second screen basket 4-1 is provided with a second drainage trough 4-3. The third screening device 5 includes a third screen basket 5-1, which is connected to the inner wall of the casing 1 via a third connecting spring 5-2. One end of the third screen basket 5-1 is provided with a third drainage trough 5-3. The side wall of the box body 1 is provided with slots corresponding to the first drainage groove 3-3, the second drainage groove 4-3 and the third drainage groove 5-3, which allow the first drainage groove 3-3, the second drainage groove 4-3 and the third drainage groove 5-3 to move with the movement of the first screen basket 3-1, the second screen basket 4-1 and the third screen basket 5-1.
[0031] The mesh of the second screen basket 4 - 1 is smaller than that of the first screen basket 3 - 1 , and the mesh of the third screen basket 5 - 1 is smaller than that of the second screen basket 4 - 1 . The second screening device 4 and the third screening device 5 have the same structure as the first screening device 3 .
[0032] A first diversion and discharge port 3-4 is provided below the first sieve basket 3-1. The first diversion and discharge port 3-4 is fixedly connected to the inner wall of the housing 1 and is funnel-shaped, with one side of the first diversion and discharge port 3-4 positioned below the first diversion trough 3-3. A second diversion and discharge port 4-4 is provided below the second sieve basket 4-1. The second diversion and discharge port 4-4 is fixedly connected to the inner wall of the housing 1 and is funnel-shaped, with one side of the second diversion and discharge port 4-4 positioned below the second diversion and discharge trough 4-3. A third diversion and discharge port 5-4 is provided below the third sieve basket 5-1. The third diversion and discharge port 5-4 is fixedly connected to the inner wall of the housing 1 and is funnel-shaped, with one side of the third diversion and discharge port 5-4 positioned below the third diversion and discharge trough 5-3.
[0033] The first diversion discharge port 3-4 is used to divert the walnuts screened by the first screen basket 3-1 to the second screen basket 4-1, the second diversion discharge port 4-4 is used to divert the walnuts screened by the second screen basket 4-1 to the third screen basket 5-1, and the third diversion discharge port 5-4 is used to collect the walnuts screened by the last third screen basket 5-1.
[0034] The other ends of the first, second, and third sieve baskets 3-1, 4-1, and 5-1 are each fixedly connected to a vibration drive device 6. This device comprises a transmission rod 6-1, the distal end of which slidably engages a rotating track 6-2. The track surface of the rotating track 6-2 exhibits an irregular, undulating structure. A traction rod 6-3 is fixedly attached to the inner side of the rotating track 6-2. The traction rod 6-3 is mounted on the output end of a motor 6-4, with the center of the output end of the motor 6-4 located at the center of the rotating track 6-2. In this embodiment, a corresponding notch 1-1 is provided in the housing 1 to allow for free movement of the transmission rod 6-1.
[0035] like Figure 5 and Figure 6 As shown, the transmission rod 6-1 is L-shaped, and one end of the transmission rod 6-1 is fixedly connected to the first screen basket 3-1, the second screen basket 4-1, or the third screen basket 5-1. The other end of the transmission rod 6-1 is provided with a rolling ball 6-1-1, which slides in conjunction with the rotating track 6-2.
[0036] The rotating track 6-2 includes a fixed portion 6-2-1 and a rotating portion 6-2-3. Both the fixed portion 6-2-1 and the rotating portion 6-2-3 are cylindrical structures. A docking slot 6-2-2 is provided at the top end of the cylindrical wall of the fixed portion 6-2-1, and a docking rail 6-2-4 is provided at the bottom end of the cylindrical wall of the rotating portion 6-2-3. The docking slot 6-2-2 and the docking rail 6-2-4 are clamped together and slide in a cooperative manner.
[0037] A curved track 6-2-5 is provided at the top of the cylinder wall of the rotating part 6-2-3. The track surface of the curved track 6-2-5 is a closed circular groove track, and the track surface is an irregular wave-shaped structure that rises and falls. The curved track 6-2-5 slides with the ball 6-1-1, and the track groove of the curved track 6-2-5 is deep, so the ball 6-1-1 will not fall out when rolling on the track surface.
[0038] The inner wall of the rotating portion 6-2-3 is fixedly connected to the traction rod 6-3, which is fixedly connected to the output end of the motor 6-4. The output end of the motor 6-4 is located at the center of the circle between the fixed portion 6-2-1 and the rotating portion 6-2-3. The rotation of the output end of the motor 6-4 drives the traction rod 6-3 to perform circular motion, thereby driving the entire rotating portion 6-2-3 to rotate. At this time, the rotation of the curved track 6-2-5 will cause the transmission rod 6-1 to vibrate up and down. Since the wave shape of the curved track 6-2-5 is irregular, the amplitude and frequency of the vibration of the transmission rod 6-1 are also irregular. Since the transmission rod 6-1 is fixedly connected to the first sieve basket 3-1, the second sieve basket 4-1 or the third sieve basket 5-1, and the first sieve basket 3-1, the second sieve basket 4-1 or the third sieve basket 5-1 are respectively connected to the box body 1 through the first connecting spring 3-2, the second connecting spring 4-2 or the third connecting spring 5-2, during this process, under the self-gravity of the first sieve basket 3-1, the second sieve basket 4-1 or the third sieve basket 5-1, the ball 6-1-1 rolls along the trajectory of the curved track 6-2-5. Therefore, the transmission rod 6-1 will transmit the vibration motion to the first sieve basket 3-1, the second sieve basket 4-1 or the third sieve basket 5-1, thereby vibrating the walnuts, so that the walnuts smaller than the mesh are screened out and the walnuts are not easy to cluster during the vibration process.
[0039] like Figures 1 to 6 As shown, the use process of the utility model is as follows:
[0040] First, walnuts are added from the feed port 2-5. When a large number of walnuts fall, they will contact the feed roller 2-2 and slide down under the rolling action of the feed roller 2-2, so that the walnuts will not be crowded and cause blockage. All motors 6-4 are started, and the motor 6-4 drives the traction rod 6-3 to rotate, thereby driving the entire rotating part 6-2-3 to rotate. The rotation of the curved track 6-2-5 will rise and fall against the transmission rod 6-1 to perform a vibrating motion. The transmission rod 6-1 transmits the vibrating motion to the first sieve basket 3-1, the second sieve basket 4-1 or the third sieve basket 5-1, thereby vibrating the walnuts, so that walnuts smaller than the mesh are screened out and the walnuts are not easily clumped during the vibration process.
[0041] Walnuts smaller than the mesh size of the first sieve basket 3-1 pass through the first sieve basket 3-1 and enter the second sieve basket 4-1 through the first diversion discharge port 3-4 for vibration screening. Walnuts larger than the mesh size flow out from the first drainage trough 3-3. Similarly, the working process of the second sieve basket 4-1 and the third sieve basket 5-1 is the same as that of the first sieve basket 3-1. At the same time, a collection container is placed below the third diversion discharge port 5-4 to collect the last screened walnuts.
[0042] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
