Detailed Description

The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.

The embodiment provides a hammer sheet type automatic discharging crusher, which comprises a crushing chamber 1, a material containing hopper 2, a cloth bag 3, a communicating pipe 4, a shell 5, a rotating shaft 6, a rotor 7, a hopper 8, a second pipe 9, a groove 10, a fan 11, a first pipe 12, a connecting rod 13, a feeding hole 14, a discharging hole 15, a protrusion 16 and an arc surface 17, and is shown in figures 1-2.

Crushing room 1 is prior art, and inside is equipped with the hammer leaf of high-speed rotation, smashes room 1 and communicates with fan 11 through second pipe 9, sets up the screen cloth at the terminal surface of crushing room 1 and the second pipe 9 junction for the qualified raw materials after smashing of screening particle diameter, these raw materials after processing can pass through the screen cloth, get into the second pipe 9 under fan 11's effect in, smash the top of room 1 and install the flourishing hopper 2 rather than the intercommunication.

The top of the fan 11 is connected with a first pipe 12, and the fan 11 is internally provided with fan blades capable of rotating at a high speed, so that the crushed raw materials passing through the screen can move according to the direction shown by an arrow when the fan blades rotate. The crushed raw material enters from one end of the first pipe 12 and moves out from the other end under the action of wind power, in the embodiment, the shape of the other first pipe 12 is similar to a U shape, and the function is as follows: 1. the moving direction of the crushed raw materials can be changed, so that the materials moving upwards in the original vertical direction move downwards in the vertical direction; 2. due to the existence of the bent pipe, wind impact is reduced, and noise is reduced; 3. the moving distance of the materials is increased, the effect of wind power is indirectly weakened, and convenience is provided for subsequent material collection.

The discharge end of the first pipe 3 is communicated with the cloth bag 4, the bottom of the cloth bag 4 is provided with a communicating pipe 5 for guiding materials into the shell 5, and the upper end and the lower end of the shell 5 in the vertical direction are opened, so that the materials can sequentially pass through the cloth bag 3, the communicating pipe 4, the shell 5 and the hopper 8 to enter a container for receiving the materials.

Rotor 7 is arranged at the position of casing 5 corresponding to communicating pipe 4, feed inlet 14, accommodating space and discharge outlet 15 are sequentially arranged in vertical direction from top to bottom in casing 5, feed inlet 14 is communicated with communicating pipe 4 and corresponds to the position of the outlet end of communicating pipe 4, and discharge outlet 15 corresponds to the position of hopper 8.

As shown in fig. 2, the cross section of the housing 5 in the radial direction of the rotor 7 is configured as a square, two protrusions 16 are arranged inside the housing 5, the protrusions 16 extend towards the horizontal direction, the surfaces of the two protrusions 16 opposite to each other are arc surfaces 17, the arc surfaces 17 have the same structure and are opposite to each other in the opening direction, the maximum distance between the two arc surfaces 17 in the radial direction of the rotor 7 is slightly larger than the diameter of the rotor 7, the gap between the rotor 7 and the arc surfaces 17 is 0.5mm-1mm, and the two arc surfaces 17 form an accommodating space. The shape formed by the two cambered surfaces 17 and the extension line is a cylindrical structure, the difference between the inner diameter of the cylindrical structure and the diameter of the rotor 7 is 0.5mm-1mm, so that the maximum distance between the two cambered surfaces 17 on the section of the rotor 7 in the radial direction is slightly larger than the outer diameter of the rotor 7, and the sections of the two cambered surfaces 17 in the radial direction of the rotor 7 are minor arcs.

A plurality of grooves 10 are circumferentially provided on the side surface of the rotor 7, the grooves 10 have a certain depth, and the extending direction of the grooves 10 is parallel to the axial direction of the rotor 7. In addition, the length of the groove 10 in the axial direction of the rotor 7 is larger than or equal to the diameter of the outlet end face of the communicating pipe 4 and smaller than or equal to the diameter of the feed end face of the hopper 8, so that the materials entering the shell 5 through the communicating pipe 4 can fall into the groove 10, and the materials in the groove 10 can all enter the hopper 8.

Therefore, when the rotor 7 rotates, the materials can fall into the groove 10 under the action of wind power and gravity, the air is lighter than the materials, the bottom materials block the air from entering the groove, all the air above the materials is forced to enter the atmosphere from the cloth bag gap, and when the groove 10 rotates to the opening facing downwards in the vertical direction, the materials can leave the groove under the centrifugal action of the rotor and enter the discharge hopper 8.

The accommodating space can also adopt other structures, specifically: casing 5 is a section of thick bamboo in addition, and casing 5 sets up feed inlet 14 and discharge gate 15 respectively in the position that corresponds with communicating pipe 4 and hopper 8, and the inside of casing 5 is accommodation space this moment for the diameter of rotor 7 slightly is less than the internal diameter that can 5, can realize above-mentioned technical purpose, consequently, when casing 5 is a section of thick bamboo, feed inlet 14 and discharge gate 15 are the opening at the upper and lower both ends of casing 5 in vertical direction promptly.

There is the interval between the inner wall of casing 5 and the side of rotor 7, and in this embodiment, rotor 7 is cylindrical, and the one end of rotor 7 is connected with connecting rod 13, and connecting rod 13 is connected with the interior drive flabellum pivoted rotor of fan, and when the flabellum rotated, can drive rotor 7 and rotate.

Connecting rod 13 and casing 5 adopt smooth sealed mode to be connected, inside connecting rod 13 part got into casing 5, connecting rod 13 kept away from the one end of rotor 7 and is connected with axis of rotation 6, and the tip of axis of rotation 6 is equipped with the belt pulley, and the belt pulley is connected with the belt, then drives the belt through the motor and rotates, and then drive belt pulley drives axis of rotation 6 and rotate for rotor 7 can rotate in casing 5 is inside.

The cloth bag 3 is provided with a plurality of air outlets, so that when materials with wind power enter the cloth bag 3, all the wind can enter the external environment through the air outlets, and the influence of the wind power on discharging is reduced. The cloth bag 3 can also be a steel pipe with a plurality of air outlet holes, and the diameter of the air outlet holes is smaller than that of the materials.

In this embodiment, the diameter of the terminal surface of the feed end of communicating pipe 4 is less than the diameter of 3 discharge end terminal surfaces of sack in addition, and the advantage lies in: when the material is more, the material can produce the part between the junction of communicating pipe 4 and sack 3 and pile up, and wind this moment is owing to lacked decurrent flow channel, consequently all wind can be from in the venthole inflow air, and then has reduced the influence of wind to the ejection of compact.

In this embodiment, the inside of the casing 5 is provided with the exhaust hole 18, and the exhaust hole 18 is arranged on the accommodating space, so that the residual air entering the accommodating space can enter the cloth bag 3 again under the action of the fan 11, and is finally discharged into the external environment from the cloth bag 3.

The embodiment of the invention is as follows: with the both ends of sack 3 and communicating pipe 4 and first pipe 3 intercommunication, throw into the raw materials and smash room 1 in, start the power of smashing room 1, motor, axis of rotation 6 this moment drives rotor 7 and rotates, places the container in the bottom of hopper 8, gets into the unnecessary residual gas of accommodation space, under the effect of fan 11, through exhaust hole 18 entering sack 3, consequently, can realize automatic discharging under the assistance that does not need personnel.
