Description

Technical Field

[0001] This utility model relates to the field of bamboo charcoal screening technology, specifically a bamboo charcoal block screening machine. Background Technology

[0002] Bamboo charcoal is typically made by pyrolyzing bamboo in a high-temperature environment, which causes a series of complex chemical reactions such as dehydration and carbonization. This pyrolysis process removes most of the moisture and volatile substances from the bamboo, leaving behind a carbonaceous material mainly composed of carbon.

[0003] After pyrolysis, the qualified bamboo charcoal is broken into blocks according to requirements. After being conveyed by a conveyor belt, the blocks are screened by a screening machine to remove small particles of bamboo charcoal powder and residue, so as to obtain purer charcoal blocks.

[0004] Existing bamboo charcoal screening machines require loading the bamboo charcoal to be screened into the screening cylinder and then moving the entire screening cylinder, which is inconvenient to operate. The frequent movement of the screening cylinder can easily increase the manual load. In addition, the existing screening machines adopt a detached structure, which requires the screening cylinder to be placed on the rollers. The rollers need to rotate the screening cylinder through friction, which can easily increase the wear and tear of parts over a long period of time. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a bamboo charcoal block screening machine, which aims to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bamboo charcoal block screening machine includes:

[0008] A support platform has an upper end fixed with a mounting frame. A drive frame is rotatably connected inside the mounting frame. A holding box is provided on the lower inner side of the drive frame. A support frame is installed on one side of the outer end of the drive frame. Several rollers are rotatably connected inside the support frame. A positioner is installed on the outer side of the drive frame near the support frame.

[0009] Preferably, the drive frame further includes a first baffle and a second baffle located inside the container, and two connecting brackets are fixed between the first baffle and the second baffle. When the container is located inside the drive frame, the connecting brackets abut against the container.

[0010] The upper side of the connecting frame is equipped with a filter screen that is fixed to the first baffle and the second baffle, and the lower side of the connecting frame is provided with two support frames that are fixed to the first baffle and the second baffle.

[0011] Preferably, a connector is fixed to the outer end of the second baffle, and a mounting plate is fixed to the upper end of the support platform near the second baffle. A servo motor is fixed to the outer end of the mounting plate, and the connector is connected to the output shaft of the servo motor.

[0012] Preferably, the outer ends of the first baffle and the second baffle are fixed with limit rings, and the inside of the mounting frame is provided with two limit grooves corresponding to the first baffle and the second baffle. Several rollers are provided inside the limit grooves, and the limit rings contact the rollers in the corresponding limit grooves.

[0013] Preferably, the outer surface of the middle part of the roller is set to be arc-shaped.

[0014] Preferably, the positioner includes a mounting bracket fixed to the outer end of the first baffle, a pull rod is provided inside the mounting bracket, and a sleeve block is sleeved on the outer side of the pull rod;

[0015] The pull rod also includes a slide rod rotatably connected to the mounting bracket. A pull ring is fixed to the end of the slide rod away from the container, and a positioning block is fixed to the end of the slide rod near the container.

[0016] Preferably, the slide rod is slidably connected to the inside of the sleeve block, and each end of the slide rod is provided with a limiting piece located inside the sleeve block. The inside of the sleeve block is provided with a sliding groove corresponding to the limiting piece.

[0017] Preferably, a return spring is sleeved on the outer side of the slide bar, located inside the sleeve block, and the return spring abuts the side of the limiting piece away from the container.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a bamboo charcoal block screening machine. The bamboo charcoal to be screened is placed in a holding box. After the holding box is placed in the drive frame, the drive frame drives the holding box to rotate, so that the bamboo charcoal blocks are continuously screened in the drive frame. When the bamboo charcoal blocks need to be screened, only the holding box needs to be moved. The operation is simple and the manual load is small.

[0020] During the rotation of the drive frame, the limiting ring contacts the roller in the corresponding limiting groove, which reduces the friction generated when the limiting ring directly contacts the limiting groove and improves the service life of the parts.

[0021] The container is fixed by a locator. When the container is in the drive frame, the pull ring drives the pull rod to rotate. When the positioning block is aligned with the slot, the pull ring is released. The spring force of the return spring pushes the limit piece, which in turn causes the pull rod to move horizontally. The positioning block engages with the slot. This structure is convenient to operate and easy to use. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6 The embodiments proposed in this application are as follows: a bamboo charcoal block screening machine includes a support platform 1, an installation frame 2 fixed at the upper end of the support platform 1, a drive frame 3 rotatably connected inside the installation frame 2, a holding box 4 provided on the lower side of the inner end of the drive frame 3, the holding box 4 is not fixed to the drive frame 3, the bamboo charcoal blocks to be screened are placed in the holding box 4, and the drive frame 3 drives the holding box 4 to rotate, so that the bamboo charcoal blocks inside the holding box 4 are tumbled, and smaller bamboo charcoal particles or residues inside the charcoal blocks are screened out.

[0031] Specifically, the drive frame 3 includes a first baffle 31 and a second baffle 32 located inside the container 4. Two connecting brackets 33 are fixed between the first baffle 31 and the second baffle 32. When the container 4 is inside the drive frame 3, the connecting brackets 33 abut against the container 4 so that the container 4 can rotate synchronously when the drive frame 3 rotates. A filter screen 34 is installed on the upper side of the connecting bracket 33, with its two ends fixed to the first baffle 31 and the second baffle 32 respectively. Smaller bamboo charcoal particles and residues can pass through the filter screen 34. Two connecting brackets 33 are provided on the lower side of the connecting bracket 33. Two support frames 35 are fixed to the first baffle 31 and the second baffle 32 respectively. The support frames 35 support the container 4 located inside the drive frame 3. A mounting plate 11 is fixed on the upper end of the support platform 1 near the second baffle 32. A servo motor is fixed to the outer end of the mounting plate 11. At the same time, a connector 301 is fixed to the outer end of the second baffle 32. The connector 301 is connected to the output shaft of the servo motor. The specific connection method can adopt the existing technology. After the servo motor is started, the drive frame 3 can be rotated as a whole through the connector 301.

[0032] For further details, please refer to Figure 3 and Figure 4 The outer ends of the first baffle 31 and the second baffle 32 are fixed with limit rings 302. The first baffle 31 and the second baffle 32 are rotatably connected to the inside of the mounting frame 2 through the corresponding limit rings 302. At the same time, the inside of the mounting frame 2 is provided with two limit grooves corresponding to the first baffle 31 and the second baffle 32. Several rollers 21 are provided inside the limit grooves. The limit rings 302 maintain the stability and smoothness of the drive frame 3 when rotating in the mounting frame 2 by contacting the rollers 21 in the corresponding limit grooves, and reduce the friction generated when the limit rings 302 directly contact the limit grooves.

[0033] For further details, please refer to Figure 1 and Figure 2 A support frame 5 is fixed on the lower side of the support platform 1 near the first baffle 31. Several rollers 51 are evenly rotated inside the support frame 5, and the outer surface of the middle part of the rollers 51 is set to be arc-shaped so as to fit with the lower end of the container 4. When the container 4 is slid out of the drive frame 3, the container 4 is supported by the rollers 51.

[0034] When screening bamboo charcoal blocks, the blocks to be screened are first placed into the holding box 4. After the holding box 4 is slid into the drive frame 3, the servo motor is started and the drive frame 3 is rotated by the connecting piece 301. The connecting frame 33 resists the holding box 4, thereby causing the drive frame 3 to rotate the holding box 4. During this process, the bamboo charcoal blocks are continuously tumbling in the drive frame 3. Smaller bamboo charcoal particles and residues fall through the filter screen 34, and the bamboo charcoal blocks are continuously screened in the drive frame 3. After screening, the holding box 4 is slid out of the drive frame 3. When screening bamboo charcoal blocks is needed again, the holding box 4 can be moved again. The operation is simple and the manual load is small.

[0035] When the container 4 is slid out of the drive frame 3, the bottom of the container 4 can be supported by the roller 51 to keep the container 4 stable when it slides out of the drive frame 3. This means that after the container 4 is pulled out of the drive frame 3, it is not necessary to pull both ends of the container 4 with both hands, further reducing the manual load.

[0036] Meanwhile, during the rotation of the drive frame 3, the limiting ring 302 contacts the roller 21 in the corresponding limiting groove, which reduces the friction generated when the limiting ring 302 directly contacts the limiting groove and improves the service life of the parts.

[0037] In further embodiments, please refer to Figure 1 , Figure 2 and Figure 5 A locator is installed on the outer end of the drive frame 3 near the support frame 5 to fix the container 4. The locator includes a mounting bracket 6 fixed to the outer end of the first baffle 31. A pull rod is rotatably connected inside the mounting bracket 6. A sleeve block 61 is sleeved on the outer side of the pull rod. The sleeve block 61 is rotatably connected to the inside of the mounting bracket 6. The pull rod includes a sliding rod 62 rotatably connected to the mounting bracket 6. The sliding rod 62 is slidably connected to the inside of the sleeve block 61. A pull ring 63 is fixed at the end of the sliding rod 62 away from the container 4. A positioning block 64 is fixed at the end of the sliding rod 62 near the container 4. A slot 41 is opened at the outer end of the container 4 corresponding to the positioning block 64 so that the container 4 can be engaged with the positioning block 64 through the slot 41. When the positioning block 64 is engaged with the slot 41, the locator fixes the container 4 in the drive frame 3.

[0038] The sliding rod 62 has a limiting piece 601 located inside the sleeve block 61 at both ends. The sleeve block 61 has a groove corresponding to the limiting piece 601, so that the rod can not only slide inside the sleeve block 61, but also drive the sleeve block 61 to rotate synchronously when the rod rotates. The outer side of the sliding rod 62 is fitted with a return spring 65 located inside the sleeve block 61. The return spring 65 abuts the side of the limiting piece 601 away from the container box 4. Without external force, the elastic force of the return spring 65 pushes the limiting piece 601, so that the rod automatically moves towards the side closer to the container box 4.

[0039] When the container 4 is located inside the drive frame 3 and needs to be fixed inside the drive frame 3, the pull ring 63 drives the pull rod to rotate. When the positioning block 64 is aligned with the slot 41, the pull ring 63 is released, and the limit piece 601 is pushed by the elastic force of the return spring 65, thereby causing the pull rod to move horizontally. The positioning block 64 engages with the slot 41, completing the fixation of the container 4. When the container 4 needs to be removed from the drive frame 3, the pull ring 63 is pulled to drive the pull rod to move horizontally. When the positioning block 64 is no longer engaged with the slot 41, the pull rod is rotated 90° so that the positioning block 64 no longer obstructs the container 4, and the container 4 can be removed from the drive frame 3.
