The side edges of the left and right support plate portions 24b, 24b are in contact with the central outer surface (arc surface) of the door 22 and are fixed to the left and right plate surfaces of the door (see FIG. 6).

  Further, in the cylinder fixing surface 24 a of the cylinder support frame 24, a vertical slit 25 having the same shape and the same size as the vertical slit 31 passes through a position corresponding to the vertical slit 31 in the center of the opening / closing lid 22. The open / close positions of the vertical slits 25 are vertically and horizontally located at four positions (four positions) corresponding to the vertical slits 32, 32, 32, 32 of the open / close lid 22. Vertical slits 26, 26, 26, and 26 having the same shape and size as the vertical slit 32 of the lid 22 are formed so as to penetrate (see FIGS. 8, 9, and 12).

  The five support arms 33 that support the movable liner portion 30 ′ pass through the central vertical slit 31 and the other four vertical slits 32 of the open / close door 22, respectively, and the cylinder fixing surface 24a. These vertical slits 25 and the other four vertical slits 26 are also formed so as to protrude onto the plate surface (outer surface) of the fixed surface 24a (FIGS. 8, 9, and 12). reference).

  A driving cylinder 27 is fixed above the vertical slit 25 of the cylinder fixing surface 24a (see FIGS. 7 and 8), and the vertical slit is formed at the tip of the vertical telescopic rod 27a of the cylinder 27. The front end (other end portion) of the support arm 33 protruding from 25 is connected by a horizontal connection pin 36 (see FIGS. 7 and 8).

  The other vertical slits 26, 26, 26, 26 of the cylinder fixing surface 24a have support arms 33, 33, 33, 33 passing through the vertical slits 32, 32, 32, 32 of the opening / closing door 22 as described above. The other end penetrates and protrudes on the cylinder fixing surface 24a, and a horizontal (left-right) rotation shaft is supported on the other end of each support arm 33, 33, 33, 33. A guide roller 35, 35, 35, 35 that is in contact with the plate surface (outer surface) of the cylinder fixing surface 24a is rotatably attached to one end of the rotating shaft (see FIG. 7). .

  In FIG. 7, the guide roller 35 is in contact with the outer surface of the cylinder fixing surface 24a on the right side of the vertical slits 26, 26 on the cylinder fixing surface 24a. The rollers 35, 35 of the left vertical slits 26, 26 are configured to contact the outer surface of the cylinder fixing surface 24a on the left side of the vertical slits 26, 26. As described above, the vertical slits 26 are provided in the upper left and right two places and the lower left and right two places around the vertical slit 25, and the guide rollers 35 are provided in the four vertical slits 26 as described above. The movable liner portion 30 'can be supported equally in the left and right directions, and the movable liner portion 30' can be smoothly slid in the vertical direction.

  Thus, the movable liner portion 30 ′ inside the open / close door 22 is supported by the five support arms 33, and the contracted position of the vertical telescopic rod 27 a of the cylinder 27 (FIG. 7A). The support arms 33 are positioned at the upper ends of the vertical slits 25 and 26 (vertical slits 31 and 32), and the movable liner portion 30 'is indicated by a broken line in FIG. It is configured to be located at a position, that is, an inner center position (stop position) of the opening / closing door 22.

  Then, when the vertical telescopic rod 27a of the cylinder 27 is extended downward from the “stop position”, the support arm 33 of the central vertical slit 25 becomes the vertical slit 25 (the vertical slit 31 of the open / close door 22). Accordingly, the other support arms 33 are also lowered along the vertical slits 26 (the vertical slits 32 of the opening / closing door 22), and the support arms 33 of the vertical slits 26 are moved downward. The rollers 35, 35, 35, 35 are smoothly lowered while rotating along the plate surface (outer surface) of the cylinder fixing plate 24a. The movable liner portion 30 ′ is indicated by the broken line in FIG. 7B from the “stop position” (the position in FIGS. 8A and 9A) indicated by the broken line in FIG. 7A. The position, that is, the position at which the lower end of the movable liner portion 30 ′ reaches the substantially lower end of the machine box 2 (or the lower ends of the slits 25, 31, etc.) with respect to the opening / closing door 22 (“moving position” (FIG. 8 (b), the position shown in FIG. 9 (b))).

  Accordingly, the movable liner portion 30 'is moved to the "stop position" (the positions shown in FIGS. 7A, 8A, and 9A) by driving the upper and lower telescopic rods 27a of the cylinder 27 to expand and contract. And the “moving position” (positions in FIGS. 7B, 8B, and 9B) can be reciprocated in the vertical direction (directions of arrows D and E). Yes.

  Therefore, as shown in FIGS. 8 and 9, the convexity of the inner surface of the machine box 2 corresponding to the space between the upper, middle, and lower rotary blades 4, 4, 4 during the rotation of the rotary blades 4, 4, 4. When deposits S1 and S2 such as mud adhere to the arc-shaped liner 30, the cylinder 27 is driven to move the movable liner portion 30 'up and down between the "stop position" and the "movement position". By reciprocating in the direction, adhering matter S1, S2 such as mud adhering to the liner 30 is abutted against (contacted with) the tip portions 4 ', 4', 4 'of the rotating blades 4, 4, 4. Thus, the deposits S1 and S2 can be peeled and removed from the convex arc-shaped liner 30 and destroyed and dropped downward (in the direction of arrow E) (FIGS. 8B and 9B). )reference).

  For example, when the movable liner portion 30 ′ is lowered from the “stop position”, the deposits S1 and S2 are brought into contact with the tip portions 4 ′ and 4 ′ of the rotating upper and middle stirring blades 4 and 4, respectively. And the deposits S1 and S2 can be removed from the liner 30. Alternatively, when the movable liner 30 ′ is lifted from the “moving position”, the deposits S1 and S2 are brought into contact with the tip portions 4 ′ and 4 ′ of the rotating lower and middle stirring blades 4 and 4, respectively. Thus, the deposits S1 and S2 can be destroyed and removed from the liner 30 (see FIGS. 8A and 8B and FIGS. 9A and 9B).

  In FIG. 7, reference numeral 37 denotes a hook for fixing the open edge side of the opening / closing door 22 to the outward convex arc-shaped upright side plate 2 ′.

  7, 42 and 42 are support arms for fixing the cylinder 27 to the cylinder fixing surface 24a, and 43 and 43 in FIG. 7 are guide grooves for moving the movable liner portion 30 'down. A space in the machine box 2 between the guide grooves 43 and 43 for forming the movable liner portion 30 'is formed.

Since the present invention is configured as described above, its operation will be described below.
The three drive motors 10, 10, 10 are simultaneously started, and the pair of high speed rotary shafts 3, 3 are rotated at high speeds in the opposite directions in the directions of arrows A and B as shown in FIG. Is rotated in the opposite direction (arrow A direction or arrow B direction) to one of the rotation shafts 3 and 3. At the same time, the vertical telescopic rods 27a of the cylinders 27 of the open / close doors 22 are continuously and repeatedly driven in the vertical direction (directions of arrows D and E).

  In this state, when the lid 6 'of the raw material supply port 6 is opened and raw materials such as gravel mixed mud are introduced into the machine box 2, the raw materials are brought into contact with the opposed rotating stirring blades 4, 4 and 4 in the upper, middle and lower stages. In the space of the gap t (see FIG. 3) between the upper and lower stirring blades 4 and 4 and the gap t (see FIG. 3) between the middle and lower stirring blades 4 and 4 on the rotating shaft 3, Decomposed and ground by contact between the crushed particles, the corners are separated, and the fine powder generated by the pulverization and grinding is scattered and released from the discharge ports 8 and 8 of the top plate 5 into the atmosphere. . The crushed particles descending due to the turbulent flow in the machine box 2 are discharged and collected from the opening 7 ′ through the discharge hopper 7. Through such a pulverization operation, raw materials such as mud, gravel and sand mixed with gravel are finely pulverized to obtain a fine particulate crushed raw material.

  During the above process, as shown in FIGS. 8 and 9, mud or the like hits the liner 40 on the inner wall of the machine box 2 and the convex arc-shaped liner 30 of the movable liner portion 30 ′ by the turbulent flow in the machine box 2. Adhering to the surface of the convex arc-shaped liner 30 between the upper and middle stirring blades 4, 4 and the surface of the convex arc-shaped liner 30 between the lower and upper stirring blades 4, 4. (See FIG. 8 (a) and FIG. 9 (a) deposits S1 and S2).

  However, during the crushing operation by the stirring blade 4 that rotates at a high speed, the movable liner portion 30 ′ is “stopped” with respect to the open / close door 22 as shown in FIG. 8A (FIG. 9A and FIG. 7A). In order to repeat sliding in the vertical direction between the “position” and the “movement position” shown in FIG. 8B (FIG. 9B, FIG. 7B), FIG. Deposits S1 and S2 such as mud adhering between the stirring blades 4 and 4 shown in a)) are lowered in the direction of arrow E by the movable liner portion 30 ', and the tip portions 4 of the rotating stirring blades 4 and 4 are rotated. It is destroyed by contacting with “4” and can be detached from the liner 30 and removed (see FIGS. 8B and 9B). Since the distance between the tip portion 4 ′ of the stirring blade 4 and the liner 30 is close (for example, about 10 mm to about 30 mm), mud or the like adhering to the liner 30 is attached to the tip portion 4 ′ of the stirring blade 4. Easily abuts and is removed.

  On the other hand, the adhering materials S1 and S2 such as mud adhering to the liner 30 when positioned at the “moving position” in FIG. 8B are raised from the “moving position” by the movable liner portion 30 ′. By doing so, it abuts against the tip portions 4 ′, 4 ′ of the rotating stirring blades 4, 4 and is broken, and can be detached from the liner 30 and removed.

  As described above, during the rotation of the stirring blades 4, 4, 4, the cylinder 27 is continuously expanded and contracted (reciprocating drive), thereby adhering and depositing mud etc. on the liner 30 of the machine box 2. Can be prevented.

  Accordingly, it is possible to effectively prevent the agitating blade 4 from being worn by deposits such as mud deposited on the convex arc liner 30.

  As described above, in the present invention, when mud or the like adheres to the surface of the convex arc-shaped liner 30 in the machine box 2, any of the convex arc-shaped liner 30 that rotates at a high speed by reciprocating up and down is provided. The deposits S1 and S2 come into contact with the tip portion 4 ′ of the stirrer blade 4 and the deposits can be effectively peeled off from the liner 30.

  In addition, since the deposits do not accumulate on the convex arc-shaped liner 30, the stirring blade 4 is worn by the deposits (the conventional deposits S 1 ′, S 2 ′, etc.) deposited and raised in the inner direction of the machine box 2. Can also be prevented.

  Further, the machine box 2 is composed of three outwardly convex arcuate upright side plates 2 ′, and each of these outwardly convex arcuate upright side plates 2 ′ is provided with a deposit removing device 20 including a movable liner portion 30 ′. Therefore, the deposits inside the machine box can be effectively removed while maintaining a high crushing ability.

  Further, the liner 30 can be smoothly moved up and down by the guide roller 35 rotating along the outer surface (24a) of the cylinder fixing plate 24, and the deposit S1, such as mud adhering to the surface of the liner 30, can be obtained. S2 can be effectively removed by the stirring blade 4 that rotates.

  Since the deposit removing device of the vertical crusher according to the present invention can effectively remove deposits such as mud inside the machine box, mud mixed with gravel, granulated slag, cobblestone, granite, waste wood, The present invention can be widely applied to vertical crushers capable of impact crushing raw materials such as felling bamboo.
