DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] The present utility model will be further described in detail below through specific embodiments:
[0013] As Figure 1 shown, an embodiment of the present utility model provides a feeding device in the production of granular fuel, which includes a support frame 1 and a discharge hopper 2 arranged on the support frame 1. The discharge hopper 2 is slidably arranged in the horizontal direction on the support frame 1. A stirring component 3 is rotatably arranged in the discharge hopper 2, and an intermittent abutting part 4 driven by the stirring component 3 to rotate is rotatably arranged outside the discharge hopper 2. A convex block 5 that intermittently slides against the intermittent abutting part 4 is arranged on the support frame 1, and an elastic resetting component 6 is further arranged between the support frame 1 and the discharge hopper 2.
[0014] When this feeding device is in use, on the one hand, the stirring component 3 rotates in the discharge hopper 2 to stir the granular fuel in the discharge hopper 2. On the other hand, during the rotation process, the stirring component 3 drives the intermittent abutting part 4 to rotate. During the rotation process, the intermittent abutting part 4 intermittently slides against the convex block 5, and with the cooperation of the elastic resetting component 6, the discharge hopper 2 slides reciprocally in the horizontal direction, so as to effectively shake and stir the granular fuel in the discharge hopper 2, which is beneficial to the discharge of the granular fuel in the discharge hopper 2 and avoids the blockage of the granular fuel in the discharge hopper 2 during the discharging process.
[0015] In this embodiment, a support plate is fixedly sleeved on the outer side of the top of the discharge hopper 2. The discharge hopper 2 is slidably connected to the support frame 1 in the horizontal direction through the support plate for reasonable arrangement.
[0016] As Figure 1 shown, according to another embodiment of the present invention, in the feeding device in the production of granular fuel, the intermittent abutting part 4 includes a cam 41. The cam 41 is connected to the stirring assembly 3 through a belt drive structure 7, and the cam 41 intermittently slides and abuts against the convex block 5.
[0017] In this embodiment, the belt drive structure 7 includes a main pulley 71 and a driven pulley 72. The main pulley 71 is connected to the stirring assembly 3; the driven pulley 72 is rotatably connected to the outer side of the discharge hopper 2 through a rotating shaft, and the driven pulley 72 and the main pulley 71 are connected by a belt 73 for transmission.
[0018] When the discharge port at the bottom of the discharge hopper 2 is opened, the stirring assembly 3 operates to stir the granular fuel in the discharge hopper 2. At the same time, the stirring assembly 3 drives the main pulley 71 to rotate. The main pulley 71 makes the driven pulley 72 rotate through the belt 73. The driven pulley 72 drives the cam 41 to rotate synchronously through the rotating shaft. During the rotation of the cam 41, it intermittently slides and abuts against the convex block 5, and cooperates with the elastic resetting member 6 to reset the sliding of the discharge hopper 2, so that the discharge hopper 2 reciprocates and shakes, which is beneficial to the discharging of the discharge hopper 2. Wherein, one end of the rotating shaft is rotatably connected to the support plate.
[0019] As Figure 1 shown, according to another embodiment of the present invention, in the feeding device in the production of granular fuel, the elastic resetting member 6 includes at least one reset spring connected between the support frame 1 and the discharge hopper 2.
[0020] In this embodiment, the support frame 1 includes two half supports 11 distributed on both sides of the discharge hopper 2. The bottom sides of the two half supports 11 are connected by a plurality of connecting blocks. The top sides of the two half supports 11 form a support platform. The support plate is slidably supported horizontally between the two support platforms; there are two reset springs, that is, one reset spring is connected between each half support 11 and the discharge hopper 2 to ensure that after the cam 41 and the convex block 5 slide and abut, the discharge hopper 2 has sufficient reset ability.
[0021] As Figure 1 shown, according to another embodiment of the present invention, in the feeding device in the production of granular fuel, a guide rod 8 for guiding the sliding of the discharge hopper 2 is connected between the support frame 1 and the discharge hopper 2 to improve the stability of the discharge hopper 2 during the sliding process in the horizontal direction.
[0022] In this embodiment, there are two guiding rods 8. One ends of the two guiding rods 8 are fixedly connected to the support plate, and the other ends of the two guiding rods 8 pass through the two half brackets 11 horizontally one by one to ensure the stable sliding of the discharge hopper 2.
[0023] In order to enable the discharge amount of the discharge port at the bottom of the discharge hopper 2 to be adjusted according to requirements, and its adjustment structure will not be stuck due to the influence of granular fuel, resulting in the obstruction of the adjustment of the discharge amount of the discharge port at the bottom of the discharge hopper 2. As Figure 1 and Figure 2 shown, according to another embodiment of the present invention, for the feeding device in the production of granular fuel, a valve assembly 9 for adjusting the opening degree is provided at the discharge port at the bottom of the discharge hopper 2. The valve assembly 9 includes a sealing plate 91 and an adjusting part. There are two sealing plates 91, which are spliced outside the discharge port for sealing; the adjusting part is connected to the two sealing plates 91 and is used to drive them to move towards or away from each other.
[0024] In this embodiment, the adjusting part includes an adjusting screw rod 92 and a guiding rod (not shown in the drawing). The adjusting screw rod 92 is rotatably arranged on one side outside the sliding direction of the sealing plate 91, and two first adjusting blocks 93 are threadedly connected thereto. The two first adjusting blocks 93 are connected to the two sealing plates 91 one by one; the guiding rod is arranged parallel to the adjusting screw rod 92 and is located on the other side outside the sliding direction of the sealing plate 91. Two second adjusting blocks are slidably sleeved thereon, and the two second adjusting blocks are connected to the two sealing plates 91 one by one.
[0025] Among them, the adjusting screw rod 92 and the guiding rod are located on different sides outside the sliding direction of the sealing plate 91. Then, when the discharge port is opened, the granular fuel discharged from the discharge port will not fall on the adjusting screw rod 92 and the guiding rod, and will not affect the movement of the first adjusting block 93 on the adjusting screw rod 92 and the movement of the second adjusting block on the guiding rod. Specifically, one end of the adjusting screw rod 92 is connected to a stepping motor 94, and the stepping motor 94 provides power to drive the adjusting screw rod 92 to rotate forward or backward. Cooperating with the movement guiding of the two second adjusting blocks on the guiding rod, the two first adjusting blocks 93 are driven to move towards or away from each other on the adjusting screw rod 92, so as to drive the two sealing plates 91 to move towards or away from each other, and the opening degree of the discharge port is adjusted to control the discharge amount of the discharge port.
[0026] As Figure 1 shown, according to another embodiment of the present invention, for the feeding device in the production of granular fuel, the stirring assembly 3 includes a stirring paddle rotatably arranged in the discharge hopper 2 and a driving motor arranged at the outer top of the discharge hopper 2. The driving motor is connected to the stirring paddle to drive the stirring paddle to rotate.
[0027] Among them, the main pulley 71 is fixedly sleeved on the end of the stirring paddle at the outer top of the discharge hopper 2. A cover plate is fixedly connected at half of the position of the feed inlet at the top of the discharge hopper 2. The cover plate supports and installs the driving motor and the stirring paddle, and reduces the probability of particulate fuel in the discharge hopper 2 splashing out from the feed inlet.
[0028] When this feeding device is in use:
[0029] Add particulate fuel into the discharge hopper 2 from the feed inlet;
[0030] Then, start the stepping motor 94 according to requirements, and adjust the distance between the two sealing plates 91 moving away from each other to adjust the opening degree of the discharge port;
[0031] Start the driving motor, the stirring paddle rotates, and at the same time, the discharge hopper 2 reciprocates horizontally along the support frame 1, and the discharge port discharges materials stably.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
