Drawings
Fig. 1 is a schematic view of the construction of the rotary squeegee assembly of the invention.
Parts, positions and numbers in the drawings: the device comprises a base plate 1, a scraper 2, a rotating wheel 3, a support 4, a vertical rod 41, a connecting rod 42, a pin 5 and a clamping groove 6.
Detailed Description
The invention will be further explained with reference to the drawings.
As shown in figure 1, the rotary wheel type scraper device comprises a rotary wheel type scraper and a base plate 1, wherein the rotary wheel type scraper comprises a scraper 2, at least two rotary wheels 3 are arranged on the scraping back of the scraper 2, the rotary wheels 3 are used for bearing the transportation capacity, and when a belt conveyor is used for replacing a new belt, a belt head is dragged onto the rotary wheels 3 and then onto a belt frame, so that the rotary wheel type scraper device is more convenient and labor-saving. Specifically, at least two clamping grooves 6 are arranged in parallel on the scraping back of the scraping plate 2, for example, three clamping grooves 6 which are parallel to each other are arranged in the drawing, a fixed shaft penetrates through the middle of each clamping groove 6, and the rotating wheel 3 penetrates through the fixed shaft. In order to ensure that the rotating wheel 3 can rotate freely, the length of the clamping groove 6 is larger than the diameter of the rotating wheel 3, and the width of the clamping groove 6 is larger than the thickness of the rotating wheel 3.
The side wings or the bottom of the scraper 2 are connected with two groups of brackets 4, and the brackets 4 are used for supporting the scraper 2. The support 4 is also used to adjust the height of the scraper 2, since the height of the belt conveyor from the ground varies. Each group of supports 4 comprises at least two vertical rods 41, the top end of each vertical rod 41 is rotatably connected with the scraper 2, the bottom ends of the vertical rods 41 are connected through connecting rods 42, and the connecting rods 42 of the two groups of supports 4 are parallel to the rotating shaft of the rotating wheel. The connecting rod 42 ensures that the vertical rods 41 in the same group synchronously rotate, and the supporting force is ensured. Specifically, as shown in fig. 1, the brackets 4 are two groups, each group of brackets 4 includes two upright rods 41 with equal length, and the top ends of the upright rods 41 of the brackets 4 in the same group are respectively rotatably connected to the two side wings of the scraper 2. In order to realize the rotation of the vertical rod 41, a pin hole is arranged at the top end of the vertical rod 41, and the pin hole is fixedly arranged on the side wing of the scraper 2 through a pin 5. The pin 5 comprises a big head pin cap and a pin shaft, wherein the big head pin cap is connected with the top end of the upright rod 41, and the pin shaft is inserted in the side wing of the scraper 2. Two sets of supports 4 are arranged in tandem on the two flanks of the scraper 2, to help maintain balance.
The height of the runner blade needs to be adjusted according to the height of the belt conveyor to find a suitable bearing position. Since the height of the scraper 2 is related to the opening of the bracket 4, i.e. the distance between the two connecting rods 42, and the larger the opening of the bracket 4 is, the more the bracket 4 is stressed and the more easily it is unstable, the connecting rods 42 of the bracket 4 are put on the mat 1 in use. As shown in fig. 1, the upper surface of the backing plate 1 is provided with an anti-slip structure, and the length or width of the backing plate 1 is not less than the farthest distance between the connecting rods 42 of the two sets of brackets 4. The backing plate 1 is a rigid member, and the two connecting rods 42 are padded on the anti-skid structure of the backing plate 1, so that the bearing capacity is improved, more importantly, the force between the supports 4 is balanced, and the integral stability can be ensured. The anti-slip structure is a structure that allows the connecting rods 42 to be stably placed on the upper surface of the pad 1, and for example, the anti-slip structure is a corrugation groove or a serration groove. The bracket 4 of the rotary wheel type scraper is matched with the base plate 1 for use, so that a stable bearing point can be provided for the dragging upper frame of the belt, and the manpower is saved.
