Description

Technical Field

[0001] The utility model relates to the technical field of elevators, and in particular to a lower scraper mechanism. Background Art

[0002] Anti-segregation elevator is a kind of equipment used to transport powdery or granular materials. Its characteristic is that it can effectively prevent the segregation of materials. This kind of elevator usually uses scrapers or other devices to prevent the material from stratification or dispersion during the transportation process, ensuring that the material can be stably transported to the destination.

[0003] When the anti-segregation elevator lifts the aggregates through the scraper, due to the inconsistent particle volumes of the aggregates, when they are bumped during transportation, small aggregates will accumulate together through the gaps between large aggregates, which will cause segregation of aggregates during transportation; at the same time, in the process of transporting the aggregates, the aggregates will rub against the inner wall of the conveyor casing, which will cause damage to the conveyor casing; in addition, the traditional anti-segregation elevator drives the scraper by rotating the chain, and then uses the scraper to move the aggregates for transportation. Therefore, the aggregates will fall into the inside of the chain during transportation, which can easily cause the chain to get stuck and unable to operate, which will ultimately affect the transmission efficiency of the aggregates.

[0035] Example 1

[0036] Reference Figures 1 to 7 As shown, it is the first embodiment of the utility model, which provides a lower scraper mechanism, the device includes a guide unit 100, including a scraper 101, an elastic component 102 symmetrically arranged on the top of the scraper 101, and a guide rod 103 arranged inside the elastic component 102;

[0037] The transmission unit 200 includes a fixing plate 201 symmetrically connected to the bottom of the scraper 101, and a linkage assembly 202 disposed on the top of the fixing plate 201;

[0038] The baffle unit 300 includes a baffle plate 301 arranged on the top of the linkage assembly 202, a sliding hole 302 opened in the baffle plate 301, a limiting assembly 303 arranged on the outer wall of the baffle plate 301, a spring 304 symmetrically connected to the bottom of the baffle plate 301, a fixed plate 305 connected between the two springs 304 and one end away from the baffle plate 301, a sliding rod 306 symmetrically slidably connected to the bottom of the baffle plate 301, and a baffle plate 307 connected to the fixed plate 305 on the side close to the baffle plate 301, so as to avoid the problem of aggregate getting stuck after falling into the chain 402.

[0039] The second slide bar 306 is sleeved with one end of the second spring 304 close to the third fixing plate 305 .

[0040] During use, when the existing equipment puts aggregate into the scraper 101, the aggregate enters between the two baffle plates 301. At this time, the aggregate drives the transmission unit 200 to operate through its own gravity, and through the adjustment of the transmission unit 200 itself, the transmission unit 200 adjusts the position of the baffle plate 301 through the limit component 303, so that the baffle plate 301 drives the elastic component 102 to adjust through the sliding hole 302 and the guide rod 103, thereby making the two baffle plates 301 move relative to each other, and making the baffle plate 301 isolate the aggregate, avoiding the friction between the aggregate and the inner wall of the transmission casing 401 during the transmission process, thereby improving the service life of the device.

[0041] Example 2

[0042] Reference Figures 1 to 6 As shown, it is the second embodiment of the utility model, which is different from the first embodiment in that the elastic component 102 includes a resistance plate 102a rotatably connected to the top of the scraper 101, a guide rod 103 connected to the resistance plate 102a, a spring 102b connected to the outer wall of the scraper 101 away from the guide rod 103, and a resistance rod 102c connected to the outer wall of the scraper 101 away from the guide rod 103, thereby achieving the effect of automatically clamping the aggregate to prevent segregation.

[0043] Furthermore, one end of the spring 102 b away from the scraper 101 is connected to the contact plate 102 a , and the spring 102 b is sleeved with one end of the contact plate 102 a away from the guide rod 103 , and the guide rod 103 is slidably connected inside the sliding hole 302 .

[0044] Furthermore, the linkage assembly 202 includes a telescopic spring rod 202a connected to the top of the fixed plate 201, a loading plate 202b connected to the top of the telescopic spring rod 202a, and a limiting slide groove 202c symmetrically opened on the top of the loading plate 202b, thereby realizing the linkage effect of the device.

[0045] Furthermore, the limiting assembly 303 includes a second fixing plate 303a connected to the side wall of the baffle plate 1 301, a sliding rod 1 303b connected to the lower surface of the second fixing plate 303a, and a roller 303c rotatably connected to the bottom end of the sliding rod 1 303b.

[0046] Furthermore, the size of the slide bar 1 303b and the size of the roller 303c are both compatible with the size of the limiting slide groove 202c, and the fixed plate 2 303a and the slide bar 1 303b both slide inside the limiting slide groove 202c, thereby preventing the aggregate from rubbing against the inner wall of the conveying housing 401 during the pushing process of the scraper 101.

[0047] During use, after the existing equipment puts aggregate between the two baffle plates 1 301, the aggregate pushes the carrier plate 202b to move toward the side close to the chain 402 by its own gravity. At the same time, during the movement of the carrier plate 202b, the carrier plate 202b synchronously squeezes the telescopic spring rod 202a, so that the carrier plate 202b drives the roller 303c to move synchronously through the limiting slide groove 202c, and then the roller 303c drives the fixed plate 2 303a through the slide rod 1 303b. The second fixing plate 303a moves toward the side close to the chain 402, so that the second fixing plate 303a drives the baffle plate 1 301 and the sliding hole 302 to move synchronously. At the same time, the sliding hole 302 contacts the guide rod 103 and starts to rotate toward the side close to the loading plate 202b with the contact plate 102a as the axis, so that the contact plate 102a drives the spring 1 102b to rotate. When the contact plate 102a rotates to contact the contact rod 102c, the contact plate 102a stops rotating, and the contact plate 102a and the contact rod 102c are 2c continues to resist and remain in a relatively static state. At the same time, since the carrying plate 202b will continue to drive the baffle plate 1 301 to move toward the side close to the chain 402, the baffle plate 1 301 will move in the downward tilting direction along the guide rod 103 through the sliding hole 302, so that the two baffle plates 1 301 move relative to each other and squeeze the aggregate, and at the same time, the baffle plate 1 301 drives the slide bar 1 303b in the inner part of the limiting slide groove 202c to the carrying plate 20 2b, and the slide bar 303b drives the roller 303c to move toward the middle of the loading plate 202b inside the limiting slide groove 202c; the two baffle plates 301 are used to squeeze the aggregate inward to prevent the aggregate from being separated during the lifting and transmission process, and the two baffle plates 301 are used to isolate the aggregate from the inner wall of the transmission casing 401 to prevent the aggregate from rubbing against the transmission casing 401 during transportation, thereby preventing the transmission casing 401 from being damaged and unusable.

[0048] In the process of the baffle plate 1 301 moving toward the middle of the loading plate 202b, the baffle plate 1 301 drives the fixed plate 305 to move synchronously through the spring 2 304, so that the fixed plate 305 drives the slide bar 2 306 and the baffle plate 2 307 to move toward the middle of the loading plate 202b. When the two baffle plates 2 307 collide with each other and the baffle plate 1 301 continues to move, the baffle plate 2 307 slides at the bottom of the baffle plate 1 301 toward the side close to the slide bar 1 303b, and the baffle plate 2 307 pulls the spring 2 304 through the fixed plate 305 to extend toward the side close to the slide bar 1 303b, and at the same time, the fixed plate 305 drives the slide bar 2 306 to slide toward the side close to the slide bar 1 303b.

[0049] The remaining structures are the same as those of Example 1.

[0050] Example 3

[0051] Reference Figure 7 , which is a third embodiment of the utility model, and which provides an anti-segregation elevator: a lifting unit 400 includes a transmission housing 401 and a chain 402 slidably connected to the inside of the transmission housing 401 .

[0052] Furthermore, the chain 402 is connected to the bottom of the scraper 101 , and the size of the scraper 101 is adapted to the size of the transmission housing 401 .

[0053] During use, after the existing equipment puts aggregate between the two baffle plates 301, the aggregate pushes the carrier plate 202b to move to the side close to the chain 402 through its own gravity, and the aggregate is blocked by the carrier plate 202b, avoiding the problem of the aggregate entering the interior of the chain 402 and causing the chain 402 to get stuck.

[0054] The remaining structure is the same as that of Example 2.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
