the upper part of the chamber 110 is provided with a discharge roller 310, one end of the discharge roller 310 is connected with a motor 3000, the motor 3000 is arranged at the upper part of the device shell 100, the discharge roller 310 can circumferentially rotate around the axis of the device shell 100 under the driving action of an output shaft of the motor 3000, a plurality of discharge holes 311 are circumferentially and equally arranged on the discharge roller 310, a chute is also arranged on the side surface of the discharge hole 311, a connecting spring 330 is arranged at the bottom of the chute arranged on the discharge hole 311, one end of the connecting spring 330 far away from the chute is elastically connected with a second arc 320, a second loading chute is arranged in the discharge roller 310, a plurality of guide tanks 312 are circumferentially arranged on the discharge roller 310, a discharge pipe 130 is arranged at the upper part of the device shell 100, the discharge pipe 130 is communicated with the second loading chute, therefore concrete materials entering the second loading chute can enter the discharge pipe 130 through the guide tanks 312, the circumferential transmission of the feeding roller 210 and the discharging roller 310 is connected with a conveying belt 400, the outer surface of the conveying belt 400 is provided with a plurality of rectangular openings 410 at equal intervals, the interval between two adjacent rectangular openings 410 is matched with the interval between two adjacent discharging openings 311, hoppers 500 are arranged outside the conveying belt 400 in a hinged mode, the hoppers 500 are a plurality of, the hoppers 500 are arranged at equal intervals along the annular surface of the conveying belt 400, in the initial state, the connecting springs two 230 and the connecting spring one 330 are not compressed, at the moment, the first arc plate 220 seals the feeding opening 211, the second arc plate 320 seals the discharging opening 311, the materials inside the first loading groove and the second loading groove do not flow out, an adjusting component 600 is arranged between the first arc plate 220 and the feeding roller 210 and between the second arc plate 320 and the discharging roller 310, when the hopper 500 moves to a first preset position at the lower portion of the chamber 110 (the first preset position is the position of the hopper 500 in the enlarged portion at C in fig. 4), the corresponding adjusting assembly 600 controls the first arc 220 so that the first arc 220 moves toward the position close to the second connecting spring 230, the second connecting spring 230 is compressed to open the feed inlet 211, so that the material in the first loading slot can enter the hopper 500 through the feed inlet 211, the hopper 500 loaded with the concrete material continues to move to a second preset position at the upper portion of the chamber 110 under the action of the conveyor belt 400 (the second preset position is the position of the hopper 500 in the enlarged portion at B in fig. 4), and at this time, the adjusting assembly 600 controls the second arc 320 so that the second arc 320 moves toward the first connecting spring 330, the first connecting spring 330 is compressed, and the discharge outlet 311 is opened, so that the concrete material in the hopper 500 can enter the second loading slot 311 through the discharge outlet 311 due to the inclination of the opening of the hopper 500 toward the position of the discharge outlet 311 under the traction of the conveyor belt 400.
In use, the first motor 3000 and the second motor 4000 are started, so that the first motor 3000 and the second motor 4000 rotate clockwise, then the concrete material is fed into the first loading groove from the feeding pipe 120, at this time, the concrete material in the feeding roller 210 is in a state of being high and low left and right in the first loading groove due to the inertia force (the left and right in the technical scheme are based on the left and right positions in the view shown in fig. 4), therefore, when the feeding hole 211 at the position of the left side of the feeding roller 210 is opened by the adjusting component 600, the concrete material can enter the hopper 500 through the feeding hole 211 and the rectangular hole 410, after the hopper 500 rotates to be far away from the first preset position, the adjusting component 600 controls the feeding hole 211 at the position corresponding to the hopper 500 in the circumferential direction of the feeding roller 210 to be closed, and after the next hopper 500 moves to the first preset position, the adjusting component 600 controls the feeding hole 211 corresponding to the feeding roller 210 in the circumferential direction to be opened, so that the concrete material is fed into the hopper 500, and the concrete material is continuously fed into the hopper 500 under the action of the conveying belt hopper 400. When the hopper 500 loaded with concrete materials moves to the second preset position, the opening of the hopper 500 faces the discharge roller 310 under the traction action of the conveyor belt 400, and the discharge hole 311 at the corresponding position on the discharge roller 310 is opened under the control of the adjusting assembly 600, so that the concrete materials in the hopper 500 are poured into the discharge roller 310 from the hopper 500, and then the concrete materials enter the discharge pipe 130 through the guide chute 312 arranged on the discharge roller 310. Since the hopper 500 in the present apparatus is opened and concrete material is added to the hopper 500 only when it is moved to the first preset position, the problem of waste caused by the concrete material falling to the bottom of the apparatus housing 100 due to the switching of the hopper 500 does not occur.
It will be appreciated that the rotational speed of the discharge roller 310 and the feed roller 210 should not be too fast in order to avoid that the concrete material inside the hopper 500 is thrown out by centrifugal force.
It can be understood that the feeding pipe 120 is not disposed at a position where concrete material can be directly added into the hopper 500, and the opening or closing of the feeding pipe 120 is controlled by the electric valve, because the frequent opening or closing of the feeding pipe 120 by the electric valve can seriously shorten the service life of the valve plate of the electric valve due to the water hammer effect, and the cost of frequently replacing the electric valve is relatively high, so that the application prospect in industry is poor.
It should be further added that the present apparatus needs to be cleaned in time after the use, and cleaning water is added into the feed roller 210 from the feed pipe 120 during cleaning, and then cleaning water and residual concrete materials inside the feed roller 210 are conveyed into the discharge roller 310 through the hopper 500, and finally the feed roller 210 and residual concrete materials and cleaning water inside the discharge roller 310 are all discharged from the discharge pipe 130, so as to avoid the first arc 220 or the second arc 320 from being able to slide due to solidification of the concrete materials in the feed roller 210 or the discharge roller 310.
It should be further noted that the rectangular openings 410 are formed on the conveyor 400, and the interval between two adjacent rectangular openings 410 and the interval between two adjacent discharge openings 311 are adapted to facilitate the transfer of concrete materials between the feeding roller 210 or the discharge roller 310 and the hopper 500.
In a further embodiment, as shown in fig. 7-12, the adjusting assembly 600 includes an adjusting lever 610, an adjusting chute 620 and a reset compression spring 630, the sides of the first arc plate 220 and the second arc plate 320 are provided with a connecting groove 640, the connecting groove 640 extends along the thickness direction of the first arc plate 220 and the second arc plate 320, the reset compression spring 630 is disposed in the connecting groove 640, one end of the adjusting lever 610 is slidably connected in the connecting groove 640, the periphery of the adjusting lever 610 abuts against one end of the reset compression spring 630, the adjusting chute 620 is provided on the sides of the feeding roller 210 and the discharging roller 310, the adjusting chute 620 includes an arc groove portion and a straight groove portion, the arc groove portion is communicated with the straight groove portion and is located at one end of the arc groove portion, in an initial state, the adjusting lever 610 is located in the arc groove portion and is far away from one end of the straight groove portion, and a stop block 700 is provided at a first preset position at the lower portion of the chamber 110 and a second preset position at the upper portion of the chamber 110.
When the feeding roller 210 rotates to the first preset position, the adjusting rod 610 is stopped by the stop block 700 and cannot rotate synchronously along with the feeding roller 210, so that the feeding roller 210 and the first arc plate 220 relatively move, the second connecting spring 230 is compressed, the feeding port 211 is opened, the concrete material in the feeding roller 210 flows into the hopper 500 through the feeding port 211, along with the extrusion rotation of the feeding roller 210, the adjusting rod 610 is gradually pushed to the straight slot position of the adjusting chute 620, and because the abutting position of the stop block 700 and the adjusting rod 610 is at the side edge of the adjusting rod 610 but not at the upper end of the adjusting rod 610, the stop block 700 can be pushed to the straight slot part by the stop block 700 when the adjusting rod 610 is separated from the limit of the arc slot part, the stop block 700 does not stop the adjusting rod 610 any more, the adjusting rod 610 is reset to the arc slot part of the adjusting chute 620 under the elastic reset action of the pressure spring 630 after the adjusting rod 610 is over the position of the stop block 700, and then the adjusting rod 610 is reset to the arc slot part of the adjusting chute 620 under the elastic reset action of the second connecting spring 230, the adjusting rod 610 is reset to stop the feeding material into the hopper 211 after the feeding port 211 is stopped by the elastic reset movement of the first arc plate 220. Similarly, when the hopper 500 moves to the second preset position along with the conveyor belt 400, the adjusting rod 610 is in stop fit with the stop block 700 at the second preset position, the discharge hole 311 is opened, and the concrete material in the hopper 500 enters the discharge roller 310 through the discharge hole 311.
