[0012] Furthermore, the center line of the pipe sleeve is parallel to the plumb line.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The photoelectric sensor senses the passing of the material, the counter counts the material conveying amount. By screwing the positioning bolt upward or downward, the positioning bolt moves out of or into the positioning hole to position the rotated turntable, changing the position of the baffle.

Detailed Description of the Preferred Embodiment

[0021] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0022] Referring to Figures 1-5 , the present utility model provides the following technical solutions: A belt conveyor with adjustable guidance includes a support 1 and two support plates 2. The two support plates 2 are respectively horizontally and fixedly connected to the front and rear ends of the upper surface of the support 1. A plurality of rotatable guide rollers 3 are equidistantly installed inside the support plates 2 from left to right. A belt 4 is sleeved on the outer wall of the guide rollers 3. The left end of the front side of the support plate 2 is provided with a motor 5. The output end of the motor 5 is connected to the front end of the leftmost guide roller 3. Under the drive of the motor 5, the guide roller 3 rotates clockwise, so that the belt 4 can convey materials from left to right. Two front and rear opposite limiting mechanisms 6 are installed outside the support plates 2. An electrostatic elimination mechanism 7 in contact with the belt 4 is installed on the top of the support 1.

[0023] As a preferred solution, further, the limiting mechanism 6 includes a box body 61 fixedly connected to the left end of the outer side of the support plate 2. A counter 62 and a photoelectric sensor 63 are respectively installed on the front and rear sides of the box body 61. The photoelectric sensors 63 on the two limiting mechanisms 6 are respectively a laser emitter and a laser receiver, and the laser receiver is electrically connected to the counter 62. The laser emitter emits laser. When the material on the belt 4 moves from left to right and blocks the laser, the laser receiver does not receive the laser and sends an electrical signal to the counter 62, and the counter 62 counts the number of materials. A rotating shaft 64 capable of rotating around its own axis is installed at the central position of the box body 61 through a bearing. A turntable 65 is installed at the bottom end of the outer wall of the rotating shaft 64. A plurality of positioning holes 66 are equidistantly arranged along the circumferential direction on the outer side of the upper surface of the turntable 65. A baffle 67 is installed at the top of the outer wall of the rotating shaft 64. The baffle 67 can limit the material and correct the position of the material on the belt 4. A positioning bolt 68 is screwed on the front end of the upper surface of the box body 61. When the positioning bolt 68 is screwed down and moves downward, the positioning bolt 68 is inserted into the positioning hole 66 to position the turntable 65. The bottom shape of the positioning bolt 68 is conical, which is convenient for the positioning bolt 68 to be aligned with the positioning hole 66 and inserted.

[0024] As a preferred solution, further, the static elimination mechanism 7 includes a mounting plate 71 fixedly connected to the top of the bracket 1. A plurality of rotatable fixed pulleys 72 are equidistantly installed in the inner cavity of the mounting plate 71 from front to back. Swing rods 73 corresponding to the fixed pulleys 72 one by one are equidistantly installed on the right side wall of the mounting plate 71 from front to back through pins. The swing rods 73 are connected to the ground wire through wires. A rotatable roller 74 is installed at the top of the swing rod 73. The roller 74 has conductivity. One end of a pull rope 75 is installed on the outer wall of the swing rod 73. The pull rope 75 is lapped with the fixed pulley 72. The other end of the pull rope 75 is tied with a counterweight 76. Under the action of the gravity of the counterweight block 76, the pull rope 75 is pulled, prompting the swing rod 73 to swing upward, so that the roller 74 contacts the surface of the belt 4. The charge on the belt 4 is transmitted into the ground through the roller 74 and the swing rod 73. A support rod 77 is horizontally installed on the left side of the mounting plate 71. A pipe sleeve 78 is installed at the left end of the support rod 77. The pull rope 75 passes through the inner cavity of the pipe sleeve 78. The center line of the pipe sleeve 78 is parallel to the plumb line. The pull rope 73 is limited by the pipe sleeve 78 to prevent the pull rope 73 from swinging.

[0025] The working principle of the present utility model is as follows:

[0026] Step 1, the guide roller 3 is driven by the motor 5 to rotate clockwise, so that the belt 4 conveys materials from left to right;

[0027] Step 2: When the laser emitter is blocked by the material, the laser receiver fails to receive the laser and sends an electrical signal to the counter 62. The counter 62 counts the quantity of the conveyed material. By screwing the positioning bolt 68 to move it up or down, the positioning bolt 68 can be moved out of or into the positioning hole 66, enabling the positioning of the rotated turntable 65. By changing the angle of the baffle 67, the baffle 67 plays a guiding role in the movement of the material, preventing the material from falling off the belt 4 during transportation.

[0028] Step 3: Under the gravitational action of the counterweight 76, the pull rope 75 is pulled, and the swing rod 73 is pulled to swing upward through the pull rope 75, making the roller 74 contact the surface of the belt 4. The charge on the surface of the belt 4 is introduced into the ground through the roller 74 and the swing rod 73, realizing the static elimination of the belt 4.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
