[0019] When the existing hammer mill is crushing large materials such as sweet potatoes, there are gaps between the hammer heads of the hammer mill. Therefore, after a large number of sweet potato pieces are added into the mill and come into contact with the hammer heads for the first time, the degree of crushing between the sweet potato pieces will vary due to their distribution positions. This will cause some sweet potato pieces to be unable to pass through the screen for feeding due to incomplete crushing. The incompletely crushed sweet potato pieces will stay in the mill for a long time and be constantly hit by the hammer heads, and even cause the incompletely crushed sweet potato pieces on the screen to be hit by the hammer heads into the holes of the screen, causing the holes of the screen to be blocked and the feeding speed of the sweet potato pieces to be affected, thereby affecting the crushing efficiency of the sweet potato pieces.

The outer shell 1 is fixed with an arc plate 1 6 and an arc plate 2 7 which are both attached to the lower side of the screen 4, the arc plate 1 6 is located on the left side, and the arc plate 2 7 is located on the right side. A baffle 8 is fixed to the left part of the upper side of the screen 4. The cross-sectional shape of the baffle 8 is a triangle, and the right side of the baffle 8 is a vertical side, and the left side of the baffle 8 is a bevel side, which is used to prevent the accumulation of sweet potato pieces on the left side of the baffle 8.

All the knife-shaped hammers 901 and all the square hammers 902 crush the sweet potato pieces alternately.

[0022] like Figure 4 and Figure 6-Figure 9 As shown, the outer part of the housing 1 is rotatably connected to a front-to-back symmetrically distributed gear 10 near the arc plate 27, the gear 10 is fixedly connected to a gear shaft, the gear shaft of the gear 10 and the sleeve 3 are transmitted through a transmission member, wherein the transmission member is composed of a belt and two pulleys, wherein the two pulleys are respectively fixed to the gear shaft of the gear 10 and the sleeve 3, the housing 1 is rotatably connected to a front-to-back symmetrically distributed gear 2 11, the gear 2 11 is a one-way gear, the gear 2 11 is meshed with the adjacent gear 10, and the gear 2 11 is meshed with the adjacent gear 10. 1 is equipped with a gear shaft. When the gear 10 rotates counterclockwise and drives the adjacent gear 2 11 to rotate clockwise, the gear 2 11 drives its gear shaft to rotate clockwise. When the gear 10 rotates clockwise and drives the adjacent gear 2 11 to rotate counterclockwise, the gear 2 11 cannot drive its gear shaft to rotate. The gear shaft of the gear 2 11 is fixedly connected with an extrusion disk 12. The extrusion disk 12 is provided with extrusion parts evenly distributed in the circumferential direction. The housing 1 is fixedly connected with a limit frame 13 symmetrically distributed in the front and rear directions. The limit frame 13 is provided with a slide groove, which is symmetrically distributed. The limit frames 13 of the cloth are all slidably connected to the sliding rod 14 through their sliding grooves. An elastic member is fixed between the limit frame 13 and the sliding rod 14, wherein the elastic member is a tension spring. The extrusion portion of the extrusion disk 12 is extruded and matched with the sliding rod 14. The sliding rod 14 is rotatably connected to the knocking hammers 15 distributed in a linear array. A group of holes distributed in an arc shape on the screen 4 and the corresponding knocking hammers 15 are all on the same vertical plane. The maximum diameter of the knocking hammer 15 is smaller than the aperture of the hole, which is used to prevent the screen 4 from being hit by all the knocking hammers during the rotation process. 15 contacts, so that the knocking hammer 15 can be inserted into the adjacent holes on the screen 4 during the rotation of the screen 4, the transmission ratio between the gear 10 and the adjacent gear 2 11 is one to four, the angle between the adjacent extrusion parts on the extrusion plate 12 is four times the angle between the adjacent holes distributed in an arc shape on the screen 4, and the extrusion plate 12 is used to rotate 40° after the screen 4 rotates 10°, so that the knocking hammer 15 can be inserted into all the holes on the same vertical plane in turn, and the knocking hammer 15 is slidably connected to the arc plate 2 7.

[0023] like Figure 8 and Fig. 9As shown, arc plate 2 7 is provided with arc grooves 16 distributed in a linear array near the knocking hammers 15 distributed in a linear array, a protrusion is provided on the lower side of the knocking hammer 15, and the protrusion is limitedly matched with the adjacent arc groove 16, and a threaded portion is provided on the left side of the knocking hammer 15, and the rotation direction of the arc groove 16 is the same as that of the threaded portion on the knocking hammer 15, which is used to enhance the unblocking force of the knocking hammer 15 on the adjacent holes on the screen 4.

[0024] When the operator needs to use the device to crush the sizing starch raw material (there are many types of sizing starch raw materials, and sweet potato pieces are taken as an example in the following), the operator adds the sweet potato pieces into the shell 1 through the feed port 101. At the same time, the operator turns on the external motor through the control panel to rotate the output shaft of the external motor and drive the pulley of the transmission roller 2 through the transmission member. The pulley of the transmission roller 2 rotates and drives it to rotate. The transmission roller 2 drives all the knife-shaped hammers 901 and all the square hammers 902 thereon to rotate through the bracket 9. The knife-shaped hammers 901 cut and crush the fibers of the sweet potato pieces, and the square hammers 902 smash the sweet potato pieces. The crushed sweet potatoes leak out of the shell 1 through the holes in the screen 4 and the discharge port 102, and the operator collects the crushed sweet potatoes.

[0025] During the rotation of the transmission roller 2, the operator turns on the two motors 5 through the control panel, and the output shafts of the motors 5 drive the adjacent missing gears 501 to rotate counterclockwise (the rotation angles described below are all based on Figure 1 The two sleeves 3 jointly drive the screen 4 to rotate counterclockwise. When the missing gear 501 rotates to lose engagement with the adjacent toothed ring 502, the screen 4 is affected by its own gravity and rotates clockwise to reset. This reciprocating process causes the screen 4 to swing back and forth, and the screen 4 drives the baffle 8 to rotate. Relying on the inertial force of the rotation of the screen 4, the baffle 8 continuously throws the sweet potato pieces on its right side from the lower side of the bracket 9 to the right side, and crushes the sweet potato pieces accumulated on the screen 4 for multiple times to prevent the sweet potato pieces from being incompletely crushed and accumulated on the screen 4, resulting in large pieces of sweet potato pieces being stuck in the holes of the screen 4, thereby affecting the feeding of sweet potatoes, causing a large amount of sweet potatoes to accumulate in the shell 1, and further affecting the crushing efficiency of the sweet potato pieces.

[0026] During the rotation of the sleeve 3, the sleeve 3 drives the adjacent gear 10 to rotate through two transmission parts, and the gear 10 drives the adjacent gear 2 11 to rotate. Since the gear 2 11 is a one-way gear, when the gear 2 11 rotates clockwise, the gear 2 11 drives the adjacent extrusion disk 12 to rotate clockwise through its gear shaft. When the gear 2 11 rotates counterclockwise, the gear 2 11 cannot drive its gear shaft to rotate. During the clockwise rotation of the extrusion disk 12 (the screen 4 rotates counterclockwise at this time), the extrusion disk 12 drives all the extrusion parts to rotate. Taking one extrusion part as an example, after the extrusion part of the extrusion disk 12 rotates to contact with the sliding rod 14 , the extrusion disk 12 rotates and squeezes the sliding rod 14 to move to the right through its extrusion part, so that the elastic part of the sliding rod 14 is gradually stretched. After the extrusion part of the extrusion disk 12 rotates to lose contact with the sliding rod 14, the elastic part of the sliding rod 14 drives it to reset, and the cycle continues. Along with the rotation of the two extrusion disks 12, the sliding rod 14 slides left and right along the two limit frames 13, and the sliding rod 14 drives all the knocking hammers 15 to slide left and right. When the knocking hammers 15 move to the left, the knocking hammers 15 are inserted into the adjacent holes on the screen 4 to dredge the holes of the screen 4 to prevent sweet potato pieces and fibers from getting stuck in the holes of the screen 4, thereby affecting the feeding of sweet potatoes.

[0027] When the hammer 15 slides left and right, the screen 4 is in the process of counterclockwise rotation. When the screen 4 rotates 10°, the gear 2 11 rotates 40°, so that when the holes of the first group of linear arrays on the screen 4 are aligned with the hammers 15 distributed in the linear array, the hammers 15 strike to the left to the limit state. When the holes of the second group of linear arrays are aligned with the hammers 15 distributed in the linear array, the hammers 15 still strike to the left to the limit state, and so on. The holes on the screen 4 are unblocked. When the knocking hammer 15 moves to the left, the raised portion of the knocking hammer 15 moves along the adjacent arc groove 16, and the raised portion of the knocking hammer 15 drives it to rotate, so that the knocking hammer 15 rotates when unblocking the adjacent holes on the screen 4, reducing the resistance encountered by the knocking hammer 15 when impacting the sweet potato pieces, and increasing the contact area and shear force between the knocking hammer 15 and the sweet potato pieces, thereby improving the unblocking force of the knocking hammer 15 on unblocking the adjacent holes on the screen 4.

[0028] When the operator uses the device to crush the sweet potato pieces, the crushed sweet potatoes fall out from the discharge port 102 through the screen 4. The operator collects and screens the crushed sweet potatoes to remove moisture and fiber from the sweet potatoes. The operator then turns off the external motor and motor 5 through the control panel, and then the operator cleans the outer shell 1 for the next use.

[0029] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 10-12As shown, it also includes a cutting frame 17, which is slidably connected to the upper side of the arc plate 27, and the cutting frame 17 is slidably connected to the housing 1. An arc-shaped cutting knife 1701 is arranged on the upper side of the cutting frame 17, and the blade on the upper side of the cutting knife 1701 faces the left side, which is used to scrape the sweet potato pieces protruding from the bottom of the screen 4. The housing 1 is rotatably connected to a reciprocating telescopic rod 18 symmetrically distributed front and back, and the telescopic end of the reciprocating telescopic rod 18 is fixedly connected to the cutting frame 17, and the fixed part of the reciprocating telescopic rod 18 is connected to the gear of the gear 2 11. The shafts are transmitted through a transmission member, wherein the transmission member consists of a belt and two pulleys, the two pulleys are respectively fixed to the fixed part of the reciprocating telescopic rod 18 and the gear shaft of the gear 2 11, a limiting block is arranged in the fixed part of the reciprocating telescopic rod 18, and the telescopic end of the reciprocating telescopic rod 18 is provided with a limiting groove which is squeezed and matched with the limiting block, and the limiting groove is an annular closed groove arranged obliquely, and the size of the linear distribution cutting knife 1701 increases from left to right, and is used to cut the sizing starch raw material stuck in the holes of the screen 4 layer by layer.

[0030] When gear 2 11 rotates clockwise, gear 2 11 drives the fixed part of the adjacent reciprocating telescopic rod 18 to rotate through its gear shaft and adjacent transmission parts, and the fixed part of the reciprocating telescopic rod 18 drives its limit block to rotate, and the limit block moves along the limit groove of the telescopic end on the adjacent reciprocating telescopic rod 18, so that the telescopic end of the reciprocating telescopic rod 18 reciprocates and retracts, and the telescopic ends of the front and rear reciprocating telescopic rods 18 retract alternately and drive the cutting frame 17 to move forward and backward together, and the cutting frame 17 drives all the cutting knives 1701 to move forward and backward. In the process of counterclockwise rotation of the screen 4, all the cutting knives 1701 cut the sweet potato pieces stuck in the holes on the screen 4 layer by layer, and increase the cutting force of the sweet potato pieces by the reciprocating movement of the cutting knives 1701, so as to prevent the sweet potato pieces stuck in the holes on the screen 4 from protruding downward, resulting in an increase in the resistance of the percussion hammer 15 inserted into the adjacent holes on the screen 4, thereby preventing the downwardly protruding sweet potato pieces from being smashed by the percussion hammer 15 and blocking the adjacent holes on the screen 4.

[0031] Embodiment 3: Based on embodiment 2, Figure 1-Figure 12 As shown, a method for using a raw material crushing device for producing sizing starch is based on the above-mentioned raw material crushing device for producing sizing starch, and the specific steps are as follows: Step 1: Add the sweet potato pieces into the housing 1 from the feed port 101, and the external motor rotates the transmission roller 2 through the pulley, and the transmission roller 2 drives the bracket 9 to rotate, and the bracket 9 drives all the knife-shaped hammers 901 and all the square hammers 902 to crush the sweet potato pieces; Step 2: The output shaft of the motor 5 drives the missing gear 501 to rotate. After the missing gear 501 is engaged with the adjacent gear ring 502, it drives it to rotate. The gear ring 502 drives the screen 4 to rotate counterclockwise through the symmetrically distributed sleeves 3. After the missing gear 501 loses engagement with the adjacent gear ring 502, the screen 4 rotates clockwise due to its own gravity, so that the screen 4 rotates back and forth and continuously lifts the sweet potato pieces upward; Step 3: During the rotation of the sleeve 3, the sleeve 3 drives the adjacent extrusion disc 12 to rotate clockwise through the transmission member, the adjacent gear 10 and the adjacent gear 2 11. The extrusion disc 12 rotates and squeezes the sliding rod 14 to move rightward through its extrusion portion. The sliding rod 14 drives all the percussion hammers 15 to slide and clear the holes of the screen 4. Step 4: When the gear 2 11 rotates clockwise, the gear 2 11 drives the fixed part of the adjacent reciprocating telescopic rod 18 to rotate through its gear shaft and the adjacent transmission member, so that the telescopic end of the reciprocating telescopic rod 18 reciprocates and retracts, and the telescopic ends of the reciprocating telescopic rod 18 symmetrically distributed front and back reciprocate and retract alternately and drive the cutting frame 17 to reciprocate together, and the cutting frame 17 drives all the cutting knives 1701 to reciprocate, and cuts the sweet potato pieces stuck in the holes on the screen 4 layer by layer; Step 5: After the sweet potato pieces are crushed, the crushed sweet potatoes fall out from the discharge port 102 through the screen 4.
