Two symmetrically arranged lip seals 198 are mounted on the right side of the tapered roller bearing 199 in fig. 10, the lip seals 198 are used for preventing broken materials from entering the tapered roller bearing 199, and as shown in fig. 11, the lip seals 198 are also mounted between the screw shaft 105 and the housing 101. As shown in fig. 14, screw shaft 105 includes a threaded portion 1051, and as shown in fig. 10, threaded portion 1051 fits within extrusion cavity 1011. As shown in fig. 13, the case 101 is formed with a discharge hole 1012 and a feed hole 1013, the feed hole 1013 and the discharge hole 1012 are communicated with the extrusion chamber 1011, as shown in fig. 9 and 11, the feed hole 1013 corresponds to the screw portion 1051, as shown in fig. 14, the screw shaft 105 includes a journal portion 1052, as shown in fig. 10, the journal portion 1052 coaxially penetrates the discharge hole 1012, as shown in fig. 10, a discharge hole 1014 is formed in a lower portion of the case 101, the discharge hole 1014 is provided in a lower side of the discharge hole 1012, as shown in fig. 10, a cavity is formed in a left portion of the case 101, the discharge hole 1014 and the discharge hole 1012 are respectively communicated with the cavity, and a connection pipe 103 for connecting with a processing apparatus of a subsequent process is installed at the discharge hole 1014, as shown in fig. 1 and 10.
The working principle of the feeding mechanism 1 is as follows: the crushed material is fed from the feeding hole 1013 and enters the extruding cavity 1011 by the action of gravity, the crushed material contacts with the screw thread 1051 of the screw shaft 105, the gear motor 104 drives the screw shaft 105 to rotate, specifically, when the screw thread 1051 is right-handed, the screw shaft 105 rotates clockwise as seen from the left side of the screw shaft 105, the crushed material is pushed leftwards in the pit of the screw thread 1051 as shown in fig. 10, the crushed material reaches the discharging hole 1012 as shown by the dotted arrow of fig. 10, the crushed material is extruded from between the inner wall of the discharging hole 1012 and the surface of the journal 1052, the crushed material then falls to the discharging hole 1014 by the action of gravity, and the crushed material enters the equipment of the subsequent process, such as an injection molding machine, through the connecting pipe 103. Since the rotation speed of the screw shaft 105 is slow, the crushed material is easily adhered to the journal portion 1052 in a small amount, and more crushed material or crushed material adhered to the journal portion 1052 temporarily is forced to fall down by the crushed material which is extruded continuously after the screw shaft 105 continues to rotate for several turns, but in some cases, the crushed material is required to be quantitatively pushed out, the screw shaft 105 only needs to rotate for one turn or for too few turns, so that the crushed material adhered to the journal portion 1052 cannot fall down in time, and the subsequent process is affected.
In order to solve the above-mentioned problems of the prior art, the present invention includes a striking mechanism 2, as shown in fig. 3 and 5, the striking mechanism 2 includes a rotation shaft 201, a cam gear 202, a pendulum 206, and a pin shaft 207, as shown in fig. 19, the pendulum 206 includes a first arm 2061, a second arm 2062, and a hammer 2063 for striking a journal portion 1052, the lower end of the second arm 2062 is fixedly connected with the hammer 2063, a connection hole 2064 is formed between the first arm 2061 and the second arm 2062, and in order to make the space reasonable arrangement, the first arm 2061 is perpendicular to the second arm 2062, as shown in fig. 5, the pin shaft 207 is rotatably connected with the connection hole 2064.

As shown in fig. 5, the cam 202 is drivingly connected to the first arm 2061, specifically, when the rotating shaft 201 rotates, the cam 202 also rotates, and the cam 202 is not circular, so that the cam 202 can be separated from the first arm 2061 after contacting the first arm 2061 during one complete rotation of the cam 202, the left end of the first arm 2061 in fig. 5 is bent upward, and the contact range between the cam 202 and the first arm 2061 is larger and the swing of the hammer 2063 to the right is larger within the range of one rotation of the cam 202 under the spatial arrangement shown in fig. 5. As can be seen in fig. 8 in combination with fig. 10, a hammer 2063 is provided outside the extrusion chamber 1011, the hammer 2063 being positioned in correspondence with the discharge hole 1014, i.e. the hammer 2063 is intended to strike the left-hand portion of the collar portion 1051 of the discharge hole 1012.
The principle of operation of the rapping mechanism 2 is: as shown in fig. 5to 7, the rotating shaft 201 drives the cam 202 to rotate, the end of the cam 202 can drive the upper side of the first arm 2061 to swing counterclockwise, it is noted that, in fig. 5, the wheel 205 is provided as a preferred embodiment, even if no wheel 205 is provided, the first arm 2061 can be driven by the end of the cam 202 to swing counterclockwise, in the specific process, in the state of fig. 5, the cam 202 rotates clockwise and just touches the upper side of the first arm 2061, in the state of fig. 6, the cam 202 drives the entire pendulum 206 to swing counterclockwise by a certain angle, so that the hammer 2063 swings outward, and in the structural feature of the box 101 as shown in fig. 5 and 13, the avoiding hole 1015 is required to avoid obstructing the movement of the hammer 2063, as shown in fig. 7, the cam 202 continues to rotate clockwise, so that the hammer 202 is separated from the first arm 2061, in the state of fig. 5, the hammer 2063 is reset by gravity to the right side surface of the shaft neck 1051, and in the state of fig. 6, the hammer is prevented from being blown down to the subsequent impact on the shaft neck 105 by the crushing material, and the subsequent impact on the crushing shaft 105 can be avoided.
Further, the cam 202 is rotatably connected to the wheel 205 for contacting the first arm 2061, specifically, as shown in fig. 18, the end of the cam 202 is fixedly connected to the boss 2021, the wheel 205 is rotatably connected to the boss 2021, the axis of the wheel 205 is parallel to the axis of the rotating shaft 201, the wheel 205 may be a deep groove ball bearing, so as to facilitate the rotation of the wheel 205, and as described above, the wheel 205 is provided on the cam 202 as a preferred embodiment, as shown in fig. 6, the wheel 205 rolls on the upper side of the first arm 2061, so as to reduce friction resistance and reduce wear.

In one embodiment, the rotating shaft 201 can be rotated by a human hand, which may cause an operator to be tired, so that a structure in which the power of the speed reduction motor 104 is transmitted to the cam gear 202 through the chain 4 is a preferred embodiment. Further, the number of teeth of the first sprocket 106 and the second sprocket 203 may be set to be the same, so that the hammer 2063 can be driven to strike the journal 1052 once every one rotation of the screw shaft 105.

The working principle of the stirrer 3 is as follows: when the stirring shaft 301 is rotated, the spring 303 agitates the crushed material at the lower part of the hopper 102, so that the crushed material can continuously fall onto the threaded part 1051 of the screw shaft 105 more easily by gravity, and the crushed material can be prevented from accumulating and staying locally.
Further, the rotating shaft 201 is in driving connection with the stirring shaft 301. The rotating shaft 201 can be connected with the stirring shaft 301 through a coupling; if the rotating shaft 201 is perpendicular to the stirring shaft 301, the rotating shaft 201 may be connected to the stirring shaft 301 through a bevel gear, and the structural mode of connecting the rotating shaft 201 to the stirring shaft 301 is not limited to the above two structures, so that the power of the gear motor 104 is transmitted to the stirring shaft 301, so as to reduce the number of motors, and save the cost.
