Description

Technical Field

[0001] The present invention relates to the technical field of press equipment, and particularly to a pressing and screening device for sugarcane juice extraction. Background Art

[0002] In the sugarcane processing industry, the sugarcane juice extraction process is crucial. As the core equipment, the performance of the pressing device directly determines the yield and quality of sugarcane juice. With the continuous growth of the market demand for sugarcane juice and related products, improving the sugarcane pressing efficiency and effect has become the focus of attention in this industry.

[0003] Currently, the common sugarcane pressing devices on the market mainly include two types: roller presses and screw presses. The roller press squeezes sugarcane through multiple groups of rollers to make the sugarcane juice flow out. However, this method has obvious drawbacks. Due to the structure of the rollers and the limitation of the squeezing method, when sugarcane passes through the gap between the rollers, it cannot be fully and evenly pressed, and a large amount of sugarcane juice will still be wrapped between the sugarcane fibers, resulting in more sugarcane juice remaining in the pressed sugarcane and a lower sugarcane juice extraction rate. The screw press relies on a screw propeller to push the sugarcane towards the outlet and squeezes the sugarcane during this process. However, in actual operation, it is also difficult to achieve an ideal pressing effect. The pressure distribution of the screw propeller is not uniform, and the sugarcane near the feed inlet is subjected to less pressure and it is difficult to fully squeeze out the internal sugarcane juice.

[0004] Whether it is a roller press or a screw press, the existing sugarcane pressing devices generally have the problem of poor pressing effect, so improvement is urgently needed. Summary of the Invention

[0099] There are two auxiliary pressing shafts 11, and the two auxiliary pressing shafts 11 are symmetrically arranged below the main pressing shaft 8. The auxiliary pressing shaft 11 is rotatably connected to the carrier frame 1. One end of the auxiliary pressing shaft 11 far from the driven gear 9 penetrates through the carrier frame 1. A auxiliary pressing gear 12 is fixedly arranged at the end of the two auxiliary pressing shafts 11 penetrating through the carrier frame 1, and both of the two auxiliary pressing gears 12 mesh with the main pressing gear 10;

[0100] A pressing part, for pressing the sugarcane entering through the feeding frame 4. The pressing part includes:

[0101] A main pressing roller 13, sleeved on the main pressing shaft 8 and fixedly connected to the main pressing shaft 8;

[0102] An auxiliary pressing roller 14, sleeved on the auxiliary pressing shaft 11 and fixedly connected to the auxiliary pressing shaft 11;

[0103] A main pressing sleeve 15, sleeved on the main pressing shaft 8;

[0104] There are two secondary pressing sleeves 16, and the two secondary pressing sleeves 16 are respectively sleeved on the two secondary pressing shafts 11;

[0105] There are three groups of pressure tooth groups 17, and the three groups of pressure tooth groups 17 are respectively arranged on the main pressing sleeve 15 and the two secondary pressing sleeves 16. The pressure tooth group 17 arranged on the main pressing sleeve 15 and the pressure tooth group 17 arranged on the secondary pressing sleeve 16 are meshed and matched with each other to press the sugarcane;

[0106] During use, the staff feeds the sugarcane through the feeding frame 4, and then controls the first motor 6 to start through the control device 2, so that the driving gear 7 fixedly connected to the output end of the first motor 6 rotates. Through the meshing between the driving gear 7 and the driven gear 9, the main pressing shaft 8 fixedly connected to the driven gear 9 rotates, and then the main pressing gear 10 fixedly connected to the main pressing shaft 8 rotates. Through the meshing between the main pressing gear 10 and the two secondary pressing gears 12, the two secondary pressing shafts 11 fixedly connected to the two secondary pressing gears 12 rotate. Through the rotation of the main pressing shaft 8 and the secondary pressing shafts 11, the main pressing rollers 13 and the secondary pressing rollers 14 respectively arranged on the main pressing shaft 8 and the secondary pressing shafts 11 rotate, and then drive the auxiliary blocks 24 arranged on the main pressing rollers 13 and the secondary pressing rollers 14 to rotate, so that the main pressing sleeve 15 and the secondary pressing sleeves 16 fixedly connected to the auxiliary blocks 24 on the main pressing rollers 13 and the secondary pressing rollers 14 rotate respectively, and then the pressure tooth groups 17 arranged on the main pressing sleeve 15 and the secondary pressing sleeves 16 rotate around the axis of the main pressing sleeve 15 and the axis of the secondary pressing sleeve 16 respectively. Through the meshing between the pressure tooth groups 17 arranged on the main pressing sleeve 15 and the secondary pressing sleeves 16, the sugarcane is pressed once;

[0107] The sugarcane after being pressed once moves under the action of the first guiding block 30 to the meshing position of the pressure tooth group 17 on the main pressing sleeve 15 and the pressure tooth group 17 on the secondary pressing sleeve 16 close to the side of the double pressing load block 26. Subsequently, the meshing between the pressure tooth groups 17 on the main pressing sleeve 15 and the secondary pressing sleeve 16 close to the side of the double pressing load block 26 is carried out, so as to realize the secondary pressing of the sugarcane after being pressed once;

[0108] Through the pressing mechanism of this device, this device can press the sugarcane twice, effectively improving the juice extraction rate of the sugarcane, thereby improving the pressing effect of this device on the sugarcane;

[0109] Refer to Figures 1 to 12 , the auxiliary part is used to assist the pressing part to press the sugarcane better, and includes:

[0110] The main electric push rod 18 is arranged on the carrier 1 and is electrically connected to the control device 2;

[0111] There are two sets of auxiliary electric push rods 19, and the two sets of auxiliary electric push rods 19 are arranged on the surface of the bearing frame 1 opposite to the main electric push rod 18. The auxiliary electric push rods 19 are electrically connected to the control device 2;

[0112] The main end plate 20 is slidably arranged on the main pressure roller 13 and is fixedly connected to one end of the main pressing sleeve 15 close to the main electric push rod 18. The main end plate 20 is used to drive the main pressing sleeve 15 to slide on the main pressure roller 13;

[0113] The auxiliary end plate 21 is slidably arranged on the auxiliary pressure roller 14 and is fixedly connected to one end of the auxiliary pressing sleeve 16 close to the auxiliary electric push rod 19. The auxiliary end plate 21 is used to drive the auxiliary pressing sleeve 16 to slide on the auxiliary pressure roller 14;

[0114] The auxiliary groove 22 is opened on the surfaces of the main pressure roller 13 and the auxiliary pressure roller 14;

[0115] The auxiliary rod 23 is fixedly arranged in the auxiliary groove 22;

[0116] The auxiliary block 24 is slidably arranged in the auxiliary groove 22 and is slidably connected to the auxiliary rod 23. The auxiliary block 24 arranged on the main pressure roller 13 is fixedly connected to the main pressing sleeve 15, and the auxiliary block 24 arranged on the main pressure roller 13 is initially located at one end of the auxiliary groove 22 close to the main electric push rod 18. The auxiliary block 24 arranged on the auxiliary pressure roller 14 is fixedly connected to the auxiliary pressing sleeve 16, and the auxiliary block 24 arranged on the auxiliary pressure roller 14 is initially located at one end of the auxiliary groove 22 close to the auxiliary electric push rod 19;

[0117] The auxiliary spring 25 is sleeved on the auxiliary rod 23, and the auxiliary spring 25 is always in a compressed state. By arranging the auxiliary spring 25, after the auxiliary block 24 loses the acting force of the main electric push rod 18 or the auxiliary electric push rod 19, the compressed auxiliary spring 25 releases elastic potential energy, so that the auxiliary block 24 moves in a direction away from the auxiliary spring 25, and cooperates with the pushing of the main electric push rod 18 or the auxiliary electric push rod 19 on the auxiliary block 24, thereby realizing the reciprocating relative movement of the main pressing sleeve 15 and the auxiliary pressing sleeve 16.

[0118] Refer to Figures 1 to 12, when the pressure tooth groups 17 provided on the main pressing sleeve 15 and the pressure tooth groups 17 provided on the auxiliary pressing sleeve 16 press the sugarcane, the staff can also start the main electric push rod 18 and the auxiliary electric push rod 19 through the control device 2, so that the auxiliary blocks 24 adjacent to the main electric push rod 18 and the auxiliary electric push rod 19 respectively slide in the auxiliary grooves 22. Furthermore, while the main pressing sleeve 15 fixedly connected to the auxiliary block 24 rotates around the axis of the main pressing roller 13 and the auxiliary pressing sleeve 16 rotates around the axis of the auxiliary pressing roller 14, the main pressing sleeve 15 and the auxiliary pressing sleeve 16 can also relatively move on the surfaces of the main pressing roller 13 and the auxiliary pressing roller 14 respectively. Furthermore, while the pressure tooth groups 17 provided on the main pressing sleeve 15 rotate around the axis of the main pressing roller 13 and the pressure tooth groups 17 provided on the auxiliary pressing sleeve 16 rotate around the axis of the auxiliary pressing roller 14, the pressure tooth groups 17 on the main pressing sleeve 15 and the pressure tooth groups 17 on the auxiliary pressing sleeve 16 can also relatively move. Thus, while the pressure tooth groups 17 press the sugarcane, they can also apply a lateral tearing force to the sugarcane, dispersing the initially crushed sugarcane stalks on the main pressing roller 13 and the auxiliary pressing roller 14, preventing the crushed sugarcane stalks from piling up together, so that the pressure during subsequent pressing can act more directly on each piece of crushed sugarcane stalk, further improving the pressing effect of the pressing mechanism on the sugarcane.

[0119] It should be noted that by providing the auxiliary part in this device, the pressure tooth groups 17 can apply a tearing force to the sugarcane while pressing the sugarcane, facilitating the pressure tooth groups 17 to tear the sugarcane, increasing the contact area between the sugarcane and the pressure tooth groups 17 to a certain extent, and further improving the pressing effect of the pressing mechanism on the sugarcane.

[0120] Refer to Figures 1 to 12 , a re-pressing mechanism, is provided on the carrier 1 and is electrically connected to the control device 2. The re-pressing mechanism is used to re-press the sugarcane that has passed through the pressing mechanism. The re-pressing mechanism includes:

[0121] A re-pressing load block 26 is fixedly provided on the carrier 1, and the surface of the re-pressing load block 26 away from the screening mechanism is set as an arc surface;

[0122] A cover plate 27 is fixedly provided on the carrier 1;

[0123] There are multiple hydraulic push rods 28, and the multiple hydraulic push rods 28 are provided on the surface of the cover plate 27 close to the re-pressing load block 26. The hydraulic push rods 28 are electrically connected to the control device 2;

[0124] The re-pressing block 29 is fixedly arranged at one end of the hydraulic push rod 28 close to the re-pressing load block 26. The surface of the re-pressing block 29 close to the re-pressing load block 26 is also set as an arc surface, and the inclined surface on the re-pressing block 29 fits with the inclined surface on the re-pressing load block 26;

[0125] It should be noted that by setting the surface of the re-pressing load block 26 away from the screening mechanism as an arc surface and the surface of the re-pressing block 29 close to the re-pressing load block 26 as an arc surface, to a certain extent, the contact area between the sugarcane after being secondarily pressed by the pressing mechanism and the re-pressing load block 26 and the re-pressing block 29 is increased, and thus to a certain extent, the pressing effect of the re-pressing mechanism on the sugarcane is improved.

[0126] The sugarcane after being secondarily pressed moves between the re-pressing load block 26 and the re-pressing block 29 under the action of the limiting block 31 and the second guiding block 32. When the sugarcane after being secondarily pressed moves between the re-pressing load block 26 and the re-pressing block 29, at this time, the control device 2 controls the hydraulic push rod 28 to start, so that the re-pressing block 29 fixedly connected to the hydraulic push rod 28 moves towards the re-pressing load block 26 until the re-pressing block 29 contacts the re-pressing load block 26, thus completing the re-pressing operation on the sugarcane after being secondarily pressed;

[0127] It should be noted that by providing the re-pressing mechanism, the device can re-press the sugarcane after being secondarily pressed by the pressing mechanism. Through the action between the arc surface on the re-pressing block 29 and the arc surface on the re-pressing load block 26, the sugarcane after being secondarily pressed can be in full contact with the re-pressing block 29 and the re-pressing load block 26, and then the juice still remaining in the sugarcane after being secondarily pressed can be pressed out, thus further improving the pressing effect of the device.

[0128] Refer to Figures 1 to 12 , the guiding part is arranged on the bearing frame 1, and the guiding part is used for guiding the pressed sugarcane. The guiding part includes:

[0129] The first guiding block 30 is located between the two sub-pressure shafts 11 and below the main pressure shaft 8. The first guiding block 30 is fixedly connected to the bearing frame 1. It should be noted that by providing the first guiding block 30, the sugarcane after being primarily pressed can be guided to the meshing position of the pressure tooth groups 17 on the main pressing sleeve 15 and the pressure tooth groups 17 on the sub-pressing sleeve 16 on the side close to the re-pressing load block 26;

[0130] The limiting block 31 is fixedly arranged on the bearing frame 1;

[0131] The second guiding block 32 is located between the double pressing block 26 and the auxiliary pressing sleeve 16 on the side away from the feeding frame 4, and is fixedly connected to the bearing frame 1; it should be noted that by setting the cooperation between the limiting block 31 and the second guiding block 32, the sugarcane after being double-pressed by the pressing mechanism can be guided between the double pressing block 26 and the double pressing block 29.

[0132] Refer to Figures 1 to 12 , a screening mechanism is arranged on the bearing frame 1 and is electrically connected to the control device 2. The screening mechanism is used to filter the bagasse in the sugarcane juice. The screening mechanism includes:

[0133] The liquid collecting frame 33 is fixedly arranged on the bearing frame 1. Four adjusting grooves 34 are symmetrically arranged in pairs in the liquid collecting frame 33. The liquid collecting frame 33 is used to collect the squeezed sugarcane juice;

[0134] There are two partition plates 35, and the two partition plates 35 are fixedly arranged in the liquid collecting frame 33;

[0135] There are two sieve plates 36, and the two sieve plates 36 are symmetrically arranged in the liquid collecting frame 33. A plurality of uniformly distributed sieve holes 37 are formed in the sieve plates 36;

[0136] A cleaning part is arranged on the sieve plate 36, and there are two groups of cleaning parts on the sieve plate 36. The cleaning part is used to clean the bagasse on the sieve plate 36. The cleaning part includes:

[0137] The fixed frame 38 is fixedly arranged on the sieve plate 36;

[0138] The second motor 39 is arranged on the fixed frame 38 and is electrically connected to the control device 2;

[0139] The cleaning screw 40 is rotatably arranged in the fixed frame 38, and one end of the cleaning screw 40 close to the cleaning motor is fixedly connected to the output end of the cleaning motor;

[0140] The sliding block 41 is slidably arranged in the fixed frame 38 and is threadedly connected to the cleaning screw 40;

[0141] The electric cleaning roller 42 is located between the two sliding blocks 41 on the same sieve plate 36, and both ends of the electric cleaning roller 42 are rotatably connected to the adjacent sliding blocks 41. The electric cleaning roller 42 is electrically connected to the control device 2, and the electric cleaning roller 42 is used to clean the bagasse on the sieve plate 36.

[0142] Refer to Figures 1 to 12After the sugarcane is pressed by the pressing mechanism and the double pressing mechanism in sequence, the squeezed juice drips onto the screen plate 36, and the sugarcane juice in the juice is screened out through the screen holes 37 on the screen plate 36 and then drips into the liquid collecting frame 33. While the liquid collecting frame 33 collects the juice, the control device 2 controls the second motor 39 to start and the electric cleaning roller 42 to rotate, so that the cleaning screw 40 fixedly connected to the output end of the second motor 39 rotates. Through the threaded transmission cooperation between the cleaning screw 40 and the sliding block 41, the sliding block 41 slides in the fixed frame 38 towards the partition plate 35, so that the electric cleaning roller 42 rotatably connected to the sliding block 41 moves towards the partition plate 35 while rotating. When the sliding block 41 moves to one end of the fixed frame 38 close to the partition plate 35, the control device 2 controls the second motor 39 to reverse, so that the sliding block 41 slides in the direction away from the partition plate 35, so that the electric cleaning roller 42 rotatably connected to the sliding block 41 moves in the direction away from the partition plate 35. In this way, the sugarcane residue filtered on the screen plate 36 is swept between the two partition plates 35 in the liquid collecting frame 33;

[0143] It should be noted that, by providing the cleaning part, the device can timely remove the sugarcane residue on the screen plate 36, thus avoiding that after the screen plate 36 filters the sugarcane juice for a long time, too much sugarcane residue accumulates on the surface of the screen plate 36, resulting in the blockage of the screen holes 37 and affecting the filtering efficiency of the sugarcane juice.

[0144] Refer to Figures 1 to 12 , the adjusting part, there are four groups, and the four groups of adjusting parts are symmetrically arranged in pairs on the liquid collecting frame 33. The adjusting part is used to adjust the inclination angle of the screen plate 36. The adjusting part includes:

[0145] The hydraulic push shaft 43 is arranged in the adjusting groove 34 and is electrically connected to the control device 2;

[0146] The adjusting block 44 is slidably arranged in the adjusting groove 34, and the adjusting block 44 is fixedly connected to the hydraulic push shaft 43;

[0147] The first end shaft 45 is rotatably arranged at one end of the screen plate 36 away from the partition plate 35, and the end of the first end shaft 45 is rotatably connected to the adjacent adjusting block 44;

[0148] The cross frame 46 is fixedly arranged on the liquid collecting frame 33;

[0149] The cross bar 47 is fixedly arranged in the cross frame 46;

[0150] The cross slider 48 is slidably arranged in the cross frame 46 and is slidably connected to the cross bar 47;

[0151] The second end shaft 49 is rotatably arranged at one end of the sieve plate 36 close to the partition plate 35, and the end of the second end shaft 49 is rotatably connected to the adjacent transverse slider 48;

[0152] The return spring 50 is sleeved on the cross bar 47, and the return spring 50 is always in a compressed state. It should be noted that by providing the return spring 50, it is convenient for the transverse slider 48 to move towards the partition plate 35.

[0153] Refer to Figures 1 to 12 , the staff can also adjust the inclination angle of the sieve plate 36 to adjust the filtering efficiency of the sieve plate 36 for sugarcane juice. The specific process is as follows. By controlling the control device 2 to start the hydraulic push shaft 43, the adjusting block 44 fixedly connected to the hydraulic push shaft 43 slides in the adjusting groove 34, and then the first end shaft 45 rotatably connected to the adjusting block 44 rises. Since the first end shaft 45 rises, one end of the sieve plate 36 close to the partition plate 35 moves away from the partition plate 35, and then the second end shaft 49 rotatably connected to the sieve plate 36 drives the transverse slider 48 to slide away from the partition plate 35, thus completing the adjustment of the inclination angle of the sieve plate 36;

[0154] It should be noted that by providing the adjusting part in this device, the inclination angle of the sieve plate 36 can be adjusted, so that the filtering efficiency of the sieve plate 36 for sugarcane juice can be adjusted. At the same time, by adjusting the inclination angle of the sieve plate 36, it is also convenient for the sugarcane residue filtered out by the sieve holes 37 to slide off the sieve plate 36, thereby improving the cleaning effect of the sugarcane residue by this device to a certain extent.

[0155] Working principle: Refer to Figures 1 to 12, during use, the staff feeds the sugarcane through the feeding frame 4, and then controls the first motor 6 to start through the control device 2, so that the driving gear 7 fixedly connected to the output end of the first motor 6 rotates. Through the meshing between the driving gear 7 and the driven gear 9, the main pressure shaft 8 fixedly connected to the driven gear 9 rotates, and then the main pressure gear 10 fixedly connected to the main pressure shaft 8 rotates. Through the meshing between the main pressure gear 10 and the two auxiliary pressure gears 12, the two auxiliary pressure shafts 11 fixedly connected to the two auxiliary pressure gears 12 rotate. Through the rotation of the main pressure shaft 8 and the auxiliary pressure shafts 11, the main pressure rollers 13 and the auxiliary pressure rollers 14 respectively arranged on the main pressure shaft 8 and the auxiliary pressure shafts 11 rotate, and then drive the auxiliary blocks 24 arranged on the main pressure rollers 13 and the auxiliary pressure rollers 14 to rotate, so that the main pressing sleeves 15 and the auxiliary pressing sleeves 16 fixedly connected to the auxiliary blocks 24 on the main pressure rollers 13 and the auxiliary pressure rollers 14 rotate respectively, and then the pressure tooth groups 17 arranged on the main pressing sleeves 15 and the auxiliary pressing sleeves 16 rotate around the axes of the main pressing sleeves 15 and the auxiliary pressing sleeves 16 respectively. Through the meshing between the pressure tooth groups 17 arranged on the main pressing sleeves 15 and the auxiliary pressing sleeves 16, the sugarcane is subjected to primary pressing;

[0156] The sugarcane after primary pressing moves under the action of the first guiding block 30 to the meshing position of the pressure tooth group 17 on the main pressing sleeve 15 and the pressure tooth group 17 on the auxiliary pressing sleeve 16 close to the side of the double-pressure load block 26. Subsequently, the meshing between the pressure tooth groups 17 on the main pressing sleeve 15 and the auxiliary pressing sleeve 16 close to the side of the double-pressure load block 26 is carried out, thus realizing the secondary pressing of the sugarcane after primary pressing;

[0157] When the pressure tooth group 17 arranged on the main pressing sleeve 15 and the pressure tooth group 17 arranged on the auxiliary pressing sleeve 16 press the sugarcane, the staff can also control the main electric push rod 18 and the auxiliary electric push rod 19 to start through the control device 2, so that the auxiliary blocks 24 adjacent to the main electric push rod 18 and the auxiliary electric push rod 19 slide in the auxiliary grooves 22 respectively. Then, while the main pressing sleeve 15 fixedly connected to the auxiliary block 24 rotates around the axis of the main pressure roller 13 and the auxiliary pressing sleeve 16 rotates around the axis of the auxiliary pressure roller 14, the main pressing sleeve 15 and the auxiliary pressing sleeve 16 can also relatively move on the surfaces of the main pressure roller 13 and the auxiliary pressure roller 14 respectively. Further, while the pressure tooth group 17 arranged on the main pressing sleeve 15 rotates around the axis of the main pressure roller 13 and the pressure tooth group 17 arranged on the auxiliary pressing sleeve 16 rotates around the axis of the auxiliary pressure roller 14, the pressure tooth group 17 arranged on the main pressing sleeve 15 and the pressure tooth group 17 arranged on the auxiliary pressing sleeve 16 can also relatively move, so that while the pressure tooth group 17 presses the sugarcane, it can also have a tearing force on the sugarcane, thereby improving the pressing effect of the pressing mechanism on the sugarcane to a certain extent;

[0158] The sugarcane after secondary pressing moves between the limiting block 31 and the second guiding block 32 towards between the repressing load block 26 and the repressing block 29. When the sugarcane after secondary pressing moves between the repressing load block 26 and the repressing block 29, at this time, the control device 2 controls the hydraulic push rod 28 to start, so that the repressing block 29 fixedly connected to the hydraulic push rod 28 moves towards the repressing load block 26 until the repressing block 29 contacts the repressing load block 26, thus completing the repressing operation on the sugarcane after secondary pressing;

[0159] After the sugarcane is successively pressed by the pressing mechanism and the repressing mechanism, the squeezed juice drops on the sieve plate 36, and the sugarcane juice in the juice is screened out through the sieve holes 37 on the sieve plate 36 and drops into the liquid collecting frame 33. While the liquid collecting frame 33 collects the juice, the control device 2 controls the second motor 39 to start and the electric cleaning roller 42 to rotate, so that the cleaning screw rod 40 fixedly connected to the output end of the second motor 39 rotates. Through the threaded transmission cooperation between the cleaning screw rod 40 and the sliding block 41, the sliding block 41 slides towards the partition plate 35 in the fixed frame 38, so that the electric cleaning roller 42 rotatably connected to the sliding block 41 moves towards the partition plate 35 while rotating. When the sliding block 41 moves to one end of the fixed frame 38 close to the partition plate 35, the control device 2 controls the second motor 39 again, so that the sliding block 41 slides in the direction away from the partition plate 35, so that the electric cleaning roller 42 rotatably connected to the sliding block 41 moves in the direction away from the partition plate 35. In this way, the sugarcane residue filtered on the sieve plate 36 is swept between the two partition plates 35 in the liquid collecting frame 33;

[0160] The staff can also adjust the inclination angle of the sieve plate 36 to adjust the filtering efficiency of the sieve plate 36 for the sugarcane juice. The specific process is as follows. The control device 2 controls the hydraulic push shaft 43 to start, so that the adjusting block 44 fixedly connected to the hydraulic push shaft 43 slides in the adjusting groove 34, and then the first end shaft 45 rotatably connected to the adjusting block 44 rises. Since the first end shaft 45 rises, the end of the sieve plate 36 close to the partition plate 35 moves in the direction away from the partition plate 35, and then the second end shaft 49 rotatably connected to the sieve plate 36 drives the cross sliding block 48 to slide in the direction away from the partition plate 35, thus completing the adjustment of the inclination angle of the sieve plate 36.
