Detailed Description

The present invention is further described in detail below with reference to examples so that those skilled in the art can practice the invention with reference to the description.

It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.

As shown in fig. 1 to 10, the material transportation integrated device of the present embodiment includes a frame 1, a motor 2 disposed on the frame 1, a synchronous transmission mechanism 3 drivingly connected to the motor 2, a climbing transmission mechanism 4 drivingly connected to a first output end 30 of the synchronous transmission mechanism, and a scraping mechanism 5 drivingly connected to a second output end 31 of the synchronous transmission mechanism;

the synchronous transmission mechanism 3 comprises a first belt wheel 32 in driving connection with the output shaft of the motor 2, a second belt wheel 34 connected with the first belt wheel 32 through a first synchronous belt 33, a first synchronous shaft 35 coaxially connected with the second belt wheel 34, a third belt wheel 36 coaxially connected with the first synchronous shaft 35, a fourth belt wheel 38 connected with the third belt wheel 36 through a second synchronous belt 37 and a second synchronous shaft 39 coaxially connected with the fourth belt wheel 38;

the climbing transmission mechanism 4 comprises a first driving roller 40 coaxially connected to the first end 350 of the first synchronizing shaft and a first driven roller 41 connected with the first driving roller 40 through a climbing belt 42, and the scraper mechanism 5 comprises a second driving roller 50 coaxially connected to the first end 390 of the second synchronizing shaft, a second driven roller 51 connected with the second driving roller 50 through a scraper belt 52 and a scraper component 53 arranged on the surface of the scraper belt 52;

the second driving roller 50 is disposed above the first driving roller 40, the climbing belt 42 is disposed obliquely, and the scraper belt 52 is parallel to the climbing belt 42.

According to the invention, the climbing belt 42 and the scraper belt 52 can be synchronously driven by the motor 2 to move upwards along the inclined plane, the climbing belt 42 is used for transporting materials, and the tail end of the scraper mechanism 5 on the scraper belt 52 can extend above the climbing belt 42 to prevent the materials from sliding downwards along the inclined plane, so that the function of preventing the materials from sliding downwards is realized. The driving of the two belts is realized through the motor 2, and the two belts synchronously move simultaneously, so that when the two belts move, the scraper component 53 is static relative to the climbing belt 42, and the material consumption on the climbing belt 42 can be well blocked. One driving mechanism saves energy consumption and is easier to control. Further specific examples are provided below for further illustration.

In a further preferred embodiment, the squeegee assembly 53 includes a plurality of mounting receptacles 530 uniformly spaced apart on the surface of the squeegee belt 52, mounting slots 531 formed in the mounting receptacles 530, and squeegees 532 rotatably coupled in the mounting slots 531. The inner end of the scraper 532 is connected in the mounting groove 531 by the rotating shaft 535, and the outer end of the scraper 532 extends out of the mounting groove 531. A threaded hole 536 penetrating to the first side blocking surface 533 of the mounting groove 531 is formed in the side portion of the mounting seat 530, a nut 538 is connected to the outer end of the adjusting stud 537, the adjusting stud 537 is inserted into the threaded hole 536 in a matching manner, and a spring 539 is arranged between the inner end of the adjusting stud 537 and the side portion of the scraper 532. A spring hole 5390 is formed at the inner end of the adjusting stud 537, one end of the spring 539 is inserted into the spring hole 5390, and the other end is connected with the side portion of the scraper 532. The adjusting stud 537 is sleeved on the spring 539 and can rotate relative to the spring 539.

Further, referring to fig. 4 to 7, the cross section of the installation groove 531 is trapezoidal, the side surface of the installation groove 531 sequentially includes a first side blocking surface 533 and a second side blocking surface 534 along the moving direction of the scraper belt 52, when there is no material blocking, the scraper 532 clings to the second side blocking surface 534 under the thrust action of the spring 539, and when the scraper 532 receives the material blocking, the scraper 532 receives the downward acting force along the inclined surface, so that the scraper 532 rotates clockwise until the spring 539 is compressed to the shortest and approaches to the second side blocking surface 534.

Through this structure setting, make scraper 532 can have better effect of blockking to the material, prevent that the material from gliding, make scraper 532 have certain rotational degree of freedom again, when meetting the powerful blockking (going into bold material), scraper 532 can cross this obstacle to prevent that motor 2 card is dead or equipment damages (if scraper 532 is broken). It will be appreciated that the ends of the scrapers 532 are able to contact the material, i.e., when the scrapers 532 are in close contact with the first side blocking surfaces 533 (as shown in fig. 1 and 4), the ends of the scrapers 532 will contact the surface of the climbing belt 42 or have a small clearance, thereby preventing the material from sliding down. Under normal conditions, because the elasticity effect of spring 539, scraper 532 keeps better contact and can not rotate with the material, can play normal anti-gliding effect, only when the resistance that scraper 532 meets was too big, just can clockwise rotation to cross the obstacle.

The depth of insertion of the adjustment stud 537 into the mounting groove 531 can be adjusted by rotating the nut 538, thereby enabling adjustment of the maximum angle at which the flight 532 can be rotated clockwise. For example, when it is desired to increase the maximum angle at which the flighting 532 can rotate clockwise (which may be over a larger obstruction, such as a larger block size in a material), rotating the nut 538 causes the adjustment stud 537 to move outwardly, decreasing in length into the mounting slot 531, and rotating the flighting 532 clockwise may move closer to the second side stop 534 (as shown in FIG. 7), thereby allowing the distance between the outer end of the flighting 532 and the ramp belt 42 to increase to over a larger obstruction. Therefore, the antiskid property of the materials can be guaranteed by adjusting the adaptability of the scraper 532 for different transported materials, and the phenomenon that the equipment is blocked due to blocking can be avoided.

Further, the bottom surface and the side surface of the inner end of the scraper 532 are connected by a circular arc surface 5320. The inner end of the scraper 532 can smoothly rotate in the mounting groove 531. Further, the corner of the inner end of the mounting groove 531 may also be provided with a circular arc surface 5320.

In a further preferred embodiment, the side boards 6 are disposed on two sides of the climbing belt 42 along the inclined plane, and the side boards 6 are connected with support rods 60 fixedly connected with the frame 1. The material can be prevented from slipping out from the side of the climbing belt 42 by providing the side barrier 6.

Furthermore, two sides of the outer end of the scraper 532 are provided with a block 5321, and the bottom surface of the block 5321 is provided with a slot 5322 for erecting on the side baffle 6. When the scraper 532 moves above the climbing belt 42, the clamping groove 5322 on the clamping block 5321 is sleeved on the side baffle 6 along the moving direction (as shown in fig. 10), the clamping block 5321 slides upwards along the inclined plane relative to the side baffle 6, the clamping block 5321 can prevent the scraper 532 from shaking along the transverse direction of the climbing belt 42, the stability of the scraper 532 can be improved, and the effect that the scraper 532 blocks the material to slide downwards can be further improved.

The top of the side baffle 6 is provided with an arc-shaped end 61, and the clamping groove 5322 is an arc-shaped groove used for being matched with the arc-shaped end 61. The arc-shaped end 61 is inserted into the arc-shaped groove in a matching manner, which is not only beneficial to the insertion of the side baffle 6 into the clamping groove 5322, but also beneficial to the smooth relative sliding between the side baffle 6 and the clamping groove 5322
