Description

Technical Field

[0001] The utility model relates to the technical field of aggregate feeding, and more specifically, to a concrete aggregate feeding machine. Background Art

[0002] Concrete aggregate refers to the granular loose material that acts as a skeleton or filler in concrete. A feeder is needed to transport the aggregate to the mixer for mixing. When making concrete, the maximum diameter of the aggregate needs to be controlled within a certain range. Existing aggregate feeders mostly use screening to remove aggregates that exceed the diameter. This solution not only increases the time for aggregate feeding, but also requires further processing of the screened aggregate, which will reduce the efficiency of concrete production.

[0003] According to the Chinese utility model publication number CN213825874U, a material discharge device for an aggregate bin of a concrete mixing station includes a material discharge box connected to the bottom of the aggregate bin, a screen is arranged in the material discharge box, and a material discharge hopper is connected to the material discharge box below the screen. The driving motor drives the transmission gear to rotate, and the driven gear meshing with the transmission gear drives the roller to rotate. The driving gear fixed on the roller meshes with the driving rack fixed on the lower surface of the screen, and the roller moves in a direction perpendicular to the axis of the roller. The cleaning teeth extend into the mesh of the screen to clean the mesh of the screen. This setting uses screening to remove larger aggregates, which not only increases the time for aggregate discharge, but also requires further processing of the screened aggregates, thereby reducing the efficiency of concrete production. Therefore, in view of this problem, how to design a concrete aggregate discharge machine has become a problem that we currently need to solve. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Refer to the instruction manual Figure 1-4 ,like Figure 1 As shown, a concrete aggregate feeder according to an embodiment of the utility model comprises a storage box 1, such as Figure 2 As shown, the inner wall of the storage box 1 is rotatably connected with a blanking piece 2, one end of the blanking piece 2 is fixedly installed with a first shaft 3, the first shaft 3 is rotatably connected to the inside of the storage box 1, and a first motor 4 is fixedly installed on one side of the storage box 1. The first shaft 3 is fixedly installed at the output end of the first motor 4. Figure 3 As shown, the inner wall of the storage box 1 is slidably connected to a fixed frame 5, and the inner wall of the fixed frame 5 is rotatably connected to a crushing roller 6, the number of the crushing rollers 6 is set to two, and the two crushing rollers 6 are axially symmetrically arranged about the vertical center line of the storage box 1, and one end of the two crushing rollers 6 is fixedly installed with a second shaft rod 7, the second shaft rod 7 is rotatably connected to the inside of the fixed frame 5, and the second shaft rod 7 is slidably connected to the inside of the storage box 1, and one end of the second shaft rod 7 is fixedly installed with a ratchet 8, a second motor 9 is fixedly installed on one side of the storage box 1, the ratchet 8 is fixedly installed on the output end of the second motor 9, a conveyor chain 10 is sleeved on the outer side of the ratchet 8, and a support frame 11 is slidably connected to one side of the storage box 1.

[0022] It should be noted that, by starting the first motor 4 to drive the first shaft 3 to rotate, the feed piece 2 is driven to rotate. Since the gap between the two adjacent baffles on the outside of the feed piece 2 is filled with aggregates, the aggregates at this position gradually coincide with the discharge port of the storage box 1 as the feed piece 2 rotates. The aggregates at this position will fall under the action of gravity and pass between the crushing rollers 6 on both sides, and then flow out of the storage box 1. The ratchet 8 is rotated by starting the second motor 9, and the crushing roller 6 is driven to rotate by the second shaft 7. At the same time, when the ratchet 8 rotates, the crushing roller 6 on the other side is driven by the transmission chain 10 to rotate. When the aggregates pass between the crushing rollers 6 on both sides, the larger aggregates will be stuck between the two crushing rollers 6 and crushed under the rotation of the crushing rollers 6, thereby achieving the purpose of crushing the larger aggregates, thereby preventing the larger aggregates from affecting the quality of the concrete.

[0023] Further, such as Figure 3 As shown, the inner side of the support frame 11 is rotatably connected with a tension wheel 12, and the tension wheel 12 is meshed with the conveying chain 10. The bottom of the support frame 11 is rotatably connected with a limit screw 13. A threaded block 14 is fixedly installed on one side of the storage box 1. The limit screw 13 and the threaded block 14 are threadedly connected. A limit plate 15 is fixedly installed on one side of the storage box 1. An adjusting screw 17 is rotatably connected to one side of the limit plate 15. A transmission threaded plate 16 is fixedly installed on one side of the fixed frame 5. The transmission threaded plate 16 and the adjusting screw 17 are threadedly connected. The transmission threaded plate 16 is slidably connected to the inside of the storage box 1, and a connecting rod 18 is fixedly installed on one end of the adjusting screw 17. Figure 2As shown, a handle 19 is fixedly mounted on one end of the adjusting screw 17 on the other side. Figure 1 As shown, a tripod 20 is fixedly installed on one side of the storage box 1, and a closing plate 21 is hinged on the top of the storage box 1. Through the setting of the closing plate 21, the closing plate 21 can be turned over by pulling the handle 22, so that the aggregate can be concentrated inside the storage box 1. The top of the closing plate 21 is fixedly installed with a handle 22, as shown in FIG. Figure 4 As shown, an adjusting gear 23 is fixedly installed on one side of the ratchet 8 on the other side. Through the setting of the adjusting gear 23, when the ratchet 8 drives the adjusting gear 23 to rotate, the adjusting gear 23 engages with the changing gear 24. Since the changing gear 24 drives the crushing roller 6 on the other side to rotate, the direction of the changing gear 24 is changed by the adjusting gear 23, so that the crushing roller 6 at this position and the crushing roller 6 on the other side rotate relative to each other, thereby achieving the purpose of crushing the aggregate. The adjusting gear 23 is rotatably connected to one side of the fixed frame 5, and the outer side of the adjusting gear 23 is meshed with the changing gear 24, and the changing gear 24 is fixedly installed on the outer side of the second shaft 7.

[0024] It should be noted that, when it is necessary to control the maximum diameter of the aggregate, the adjusting screw 17 is rotated by rotating the handle 19, and the connecting rod 18 is transmitted so that the adjusting screws 17 on both sides can be simultaneously present, thereby causing the transmission threaded plates 16 on both sides to slide simultaneously, and driving the fixed frames 5 on both sides to slide, thereby causing the crushing rollers 6 to slide, thereby achieving the purpose of controlling the distance between the crushing rollers 6 on both sides, so that when the aggregate reaches this length, it can be crushed by the crushing rollers 6, and at the same time, the tensioning wheel 12 is lowered by rotating the limit screw 13, so that the conveying chain 10 can be in a taut state, so that the ratchet wheels 8 on both sides can rotate normally, thereby achieving the purpose of flexibly controlling the size of the aggregate.

[0025] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
