Examples

According to the applicant's search, a material scattering machine is mentioned in the issued Chinese patent with publication number CN201823586U, which includes at least two licker-in, a power device for driving the licker-in to rotate and a transmission device for connecting the licker-in and the power device. The licker-in is horizontally arranged in a stepped manner from top to bottom in the discharging hopper of the double-roller crusher. The thorn cones on the thorn roller surface can be arranged according to double spiral lines. The licker-in is arranged horizontally in a stepped manner from top to bottom in the discharging hopper of the double-roller crusher, so that all large materials can pass through the licker-in, and meanwhile, the licker-in on the licker-in surface is arranged according to double spiral lines, so that the massive materials can be fully cut and scattered.

However, the prior art represented by the above patent still has the following technical problems:

The position between the pivot is fixed each other, and then makes the device of scattering only can break up the material of fixed throughput, can lead to the device to break up inhomogeneous when the material is too little, causes the pivot of the device to block easily when the material is too big to cause the device to become invalid.

In order to solve the above technical problems, this embodiment provides an SV scattering spreader. The SV break-up spreader as shown in fig. 2 and 3 includes a mounting frame 1, a roller shaft 2, and a break-up unit 3. The two roller shafts 2 are respectively named as a first shaft 21 and a second shaft 22 as shown in fig. 3 for convenience of description. Wherein the first shaft 21 is rotatably mounted in the mounting frame 1 and the second shaft 22 is slidably mounted in the mounting frame 1 and rotates relative to the mounting frame 1. The scattering unit 3 is sleeved outside the roll shafts 2 as shown in fig. 6 and distributed along the axis of the roll shafts 2, and the two roll shafts 2 rotate in opposite directions along the W direction as shown in fig. 3 to drive the scattering unit 3 to scatter materials. The second shaft 22 slides in the direction N1 with respect to the mounting frame 1 to reduce the distance H between the two roller shafts 2, and thus the distance between the scattering units 3 on the two roller shafts 2. The second shaft 22 slides in the N2 direction with respect to the mounting frame 1 to increase the distance H between the two roller shafts 2, and thus the distance between the scattering units 3 on the two roller shafts 2.

It should be noted that, the two roll shafts 2 may be manually driven by a handle, or may be driven by a driving motor, and as shown in fig. 1, the embodiment adopts two driving motors to drive the two roll shafts 2 in a one-to-one correspondence. The driving motor needs to be matched with the two roll shafts 2 by adopting a speed reducer, and is changed into a servo motor produced by an eastern motor. In the prior art, the driving motor will not be described herein.

Through the above-mentioned structure, the SV scattering distributor provided by this embodiment can adjust the distance between the two roller shafts 2 according to the throughput of the material. Specifically, when there is less material, the second shaft 22 may be slid in the N1 direction, so that the distance H between the two roller shafts 2 becomes smaller. And then the distance between the scattering units 3 on the two roll shafts 2 becomes smaller, so that the two roll shafts 2 can be respectively abutted with two sides of the material. Thereby facilitating the scattering units 3 on the two roll shafts 2 to scatter and break less materials.

When the material is excessively large, the second shaft 22 may be slid in the N2 direction, so that the distance H between the two roller shafts 2 becomes large. And then make the distance between the unit 3 of scattering on two roller 2 grow to make things convenient for the operator to put into between two roller 2 with the material, so that the unit 3 of scattering on two roller 2 is broken the material dispersion.

Thus, the operator can adjust the apparatus to accommodate different throughput of material by adjusting the second shaft 22 in the N1 and N2 directions.

Based on the above, in order to enable the second shaft 22 to move and fix in the N1 direction and the N2 direction with respect to the mounting frame 1, the mounting frame 1 includes a housing 11, a slider 12, and a driving piece 13 as shown in fig. 1. The first shaft 21 is rotatably mounted in the housing 11 by bearings as shown in fig. 5. As shown in fig. 5, the casing 11 is provided with an opening, two edges of the opening parallel to the direction N1 and the direction N2 are provided with guide rails, and two sides of the slider 12 are respectively slidably mounted on the guide rails of the two edges. And moves in the N1 direction and the N2 direction with respect to the housing 11. One end of the second shaft 22 is rotatably mounted on the slider 12 by means of a bearing. It should be noted that, as shown in fig. 1, the number of the sliding blocks 12 and the driving members 13 is two, and the two sliding blocks 12 and the driving members 13 are respectively located on two sides of the housing 11 perpendicular to the axis of the roller shaft 2. The other end of the second shaft 22 is located in the housing 11 and is rotatably mounted on the other slider 12 by means of a bearing. As shown in fig. 3, a feeding hole 111 and a discharging hole 112 are formed in the shell 11, and the two roll shafts 2 are parallel to each other and are located between the feeding hole 111 and the discharging hole 112. The driving member 13 is connected to the housing 11 and the slider 12, respectively, for driving the slider 12 to move in the N1 direction and the N2 direction relative to the housing 11. Thus, as shown in fig. 5, the operator can move the slide 12 in the direction N1 and N2 by the driving member 13 as shown in fig. 3 to move the second shaft 22 toward and away from the first shaft 21 to adjust the apparatus to accommodate different throughput of material.

More preferably, the operator can make the distance of the movement of the two ends of the second shaft 22 in the direction approaching the first shaft 21 different by adjusting the driving members 13 at the two ends of the second shaft 22 so that the second shaft 22 is not parallel to the first shaft 21. To adjust the throughput at both ends of the second shaft 22. It should be noted that, the two ends of the second shaft should be rotatably connected with the slider by adopting a aligning bearing.

More preferably, in order to facilitate the operator to clean the material fragments on the two roll shafts 2, an access hole corresponding to each of the two roll shafts 2 is formed in the housing 11 as shown in fig. 3, and an end cover 113 is provided on the access hole to close the access hole.

Based on the above, in order to enable the driving member 13 to move the slider 12 in the N1 direction and the N2 direction. The driving member 13 includes a screw 131 and a rotating sleeve 132 as shown in fig. 5. One end of the screw 131 is rotatably mounted on the slider 12. The rotating sleeve 132 is mounted on the housing 11 and is sleeved outside the other end of the screw 131. The rotating sleeve 132 is in threaded engagement with the screw 131. Thus, the operator can rotate the rotating sleeve 132 to drive the screw 131 to move along the direction N1 and the direction N2, so as to drive the slider 12 to move along the direction N1 and the direction N2.

Based on the above, in order to enable the breaking up unit 3 to break up the material. The break-up unit 3 includes a mounting sleeve 31 and a break-up member 32 as shown in fig. 7. The mounting sleeve 31 is sleeved outside the roller shaft 2 as shown in fig. 6. The scattering members 32 are mounted on the circumferential side of the mounting sleeve 31 and are uniformly distributed around the circumferential side of the mounting sleeve 31. The scattering member 32 has a first cutter end, and as shown in fig. 6, the line of the scattering member 32 adjacent to the axis of the roller shaft 2 forms an angle with the axis of the roller shaft 2. Thus, the scattering pieces 32 of the scattering unit on the same roll shaft 2 can be prevented from abutting against the material at the same time, and further, the situation that the roll shaft 2 is blocked due to the overlarge driving force required when the roll shaft 2 rotates can be prevented.

As shown in fig. 10, the stopper rings 202 abutting the mounting bush 31 are attached to both sides of the roller shaft 2 to prevent the mounting bush 31 from moving on the axis of the roller shaft 2. The retainer 202 may be a collar.

Based on the above-described basis. The diffuser 32 has a first guide surface 321, a second guide surface 322, and a third guide surface 323 as shown in fig. 9. The first guiding surface 321 is perpendicular to the circumferential side of the mounting sleeve 31 and is used for abutting against the material. The second guiding surface 322 forms an angle with the first guiding surface 321. The first bit end is located at the juncture of first guide surface 321 and second guide surface 322. Thus, when the first cutter head pierces the material, the first guiding surface 321 abuts against the material to drive the material to form a certain included angle with the first guiding surface 321. And when the first guiding surface 321 rotates around the axis of the roll shaft 2, the materials can be smashed, so that the roll shaft 2 rotates to drive the first cutter head end and the second guiding surface 322 to collide with the materials to break up the materials. The third guide surface 323 is tangential to the mounting sleeve 31 on the side of the mounting sleeve 31. The third guide surface 323 is connected to the second guide surface 322 on a side facing away from the mounting sleeve 31. And forms a second bit end with the second guide surface 322 for breaking up material. The third tool bit also can insert in the material like this and smash the material to make break up piece 32 and can smash the material twice and then make the material evenly smash in a rotation.

The scattering member 32 may be a screw tooth provided around the circumferential side of the roller shaft or a hammer head attached to the attachment sleeve.

It should be noted that, as shown in fig. 9, the first guide surface 321 and the second guide surface 322 form an angle α that satisfies 45 ° < α < 75 °, and exemplary angles α may be 45 °, 60 °, 75 °. It is apparent that the angle of alpha can affect the shape and quality of the cut surface. When alpha is more than 75 degrees, the pressure generated when the first cutter head end collides with materials is smaller, so that the scattering effect is poor, and when alpha is less than 45 degrees, the abrasion of the first cutter head is aggravated, the strength of the first cutter head is reduced, and the service life of the scattering unit 3 is shortened. The second guide surface 322 and the third guide surface 323 form an angle beta which satisfies 140 DEG < beta < 170 deg. As shown in fig. 9, β decreases with increasing α, and increases with decreasing α.

Based on the above-described basis. The SV breaking up spreader as shown in FIG. 10 also includes gear keys 4. A key groove 201 corresponding to the gear key 4 is formed on the peripheral side of the roller shaft 2. The key groove 201 extends along the axis of the roller shaft 2. As shown in fig. 10, the mounting sleeve 31 is provided with a positioning groove 311 corresponding to the gear key 4. As shown in fig. 4, a part of the gear key 4 is located in the key groove 201, and the positioning groove 311 is sleeved outside another part of the gear key 4 located outside the key groove 201. This allows the rotation of the roller shaft 2 to rotate the mounting sleeve 31. The connecting line of the midpoints of the positioning grooves 311 adjacent along the axis of the shaft is wound around the outer periphery of the roller shaft 2. Such that the line of the break-up members 32 adjacent along the axis of the roller shaft 2 as shown in fig. 6 is at an angle to the axis of the roller shaft 2.

It can be seen from the above that the SV scattering distributor provided in this embodiment can adjust the distance between the two roller shafts 2 according to the amount of the material, and can uniformly scatter the material.

The above description is merely an embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present utility model, and it is intended to cover the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
