Description
Technical Field
[0001] This utility model relates to a concrete auxiliary material feeding device, specifically to a small-sized double-spiral concrete precast component feeding machine. Background Technology
[0002] During the production of precast concrete components, numerous auxiliary materials need to be added. Currently, small and medium-sized enterprises add these materials manually by weighing, which is inefficient and poses safety risks to the health of production workers.
[0003] Therefore, there is an urgent need for a concrete precast component placing machine for small and medium-sized enterprises. It should have a simple structure, low cost, and be easy for small and micro enterprises to purchase and invest in production. It should automatically and quantitatively feed and place materials, improve production efficiency, reduce reliance on personnel, and reduce the impact on the health of production workers. Utility Model Content
[0004] This utility model provides a small-scale double-helix concrete feeding machine for precast concrete components. It has a simple structure, low cost, and is convenient for small and micro enterprises to purchase and invest in production. It automatically and quantitatively feeds and distributes materials, improves production efficiency, reduces reliance on personnel, and reduces the impact on the health of production workers.
[0005] The present invention adopts the following technical solution:
[0006] A small-scale precast concrete component double-spiral feeding machine includes a funnel-shaped feed hopper and a support fixedly connected to the feed hopper for fixation. Several discharge mechanisms are fixedly provided at the outlet of the feed hopper. Each discharge mechanism includes a column fixedly installed horizontally at the outlet of the feed hopper, an extrusion screw rotatably installed inside the column, an L-shaped mounting frame fixedly installed at the lower edge of the column, a weighing sensor fixedly installed on the mounting frame, and a receiving hopper fixedly installed on the weighing sensor. The receiving hopper is provided with an opening and closing mechanism for opening and closing the discharge port of the receiving hopper.
[0007] The opening and closing mechanism includes a closing plate, a hinge for rotatably connecting the closing plate and the hopper, a mounting plate fixed on the outer wall of the hopper, an opening and closing motor fixed on the mounting plate, and a swing rod fixedly connected to the power output shaft of the opening and closing motor for driving the closing plate.
[0008] In order to improve the extrusion effect of the material in the feed hopper and the quantitative control of the material, an extrusion motor for driving the extrusion screw is fixed on the column. The extrusion motor is a servo geared motor.
[0009] Meanwhile, in order to improve discharge efficiency while taking into account mechanical strength and material costs, the discharge mechanism is divided into two parts.
[0010] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: This utility model has two discharge mechanisms equipped with extrusion screws at the bottom of the feed hopper, and a receiving hopper with quantitative weighing function is configured at the discharge port of the discharge mechanism. The structure is simple, the cost is low, the dependence on personnel is reduced, and the quantitative and rapid feeding and distribution of concrete auxiliary materials can be achieved, which can meet the procurement and production needs of small and micro enterprises.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0019] See Figures 1 to 6A small-scale precast concrete component double-spiral feeding machine includes a funnel-shaped feed hopper 1 and a support 11 fixedly connected to the feed hopper 1 for fixing. Several discharge mechanisms 2 are fixedly provided at the outlet of the feed hopper 1. The discharge mechanism 2 includes a column 21 fixedly provided at the outlet of the feed hopper 1 in a horizontal direction, an extrusion screw 22 rotatably provided inside the column 21, an L-shaped mounting frame 23 fixedly provided at the lower edge of the column 21, a weighing sensor 24 fixedly provided on the mounting frame 23, and a receiving hopper 25 fixedly provided on the weighing sensor 24. The receiving hopper 25 is provided with an opening and closing mechanism 3 for opening and closing the discharge port of the receiving hopper 25. The opening and closing mechanism 3 includes a closing plate 31, a hinge 32 for rotatably connecting the closing plate 31 and the hopper 25, a mounting plate 33 fixedly installed on the outer wall of the hopper 25, an opening and closing motor 34 fixedly installed on the mounting plate 33, and a swing rod 35 fixedly connected to the power output shaft of the opening and closing motor 34 for driving the closing plate 31.
[0020] See Figures 1 to 6 To improve the extrusion effect and quantitative control of the material in the feed hopper 1, an extrusion motor 211 for driving the extrusion screw 22 is fixed on the column 21. This extrusion motor 211 is a servo geared motor. At the same time, to improve the discharge efficiency while taking into account mechanical strength and material cost, there are two discharge mechanisms 2.
[0021] Working principle: The feed hopper 1 is used to receive the material put in by the previous process. Under the action of the extrusion screw 22, the material falls into the receiving hopper 25 with weighing function. When the weight reaches the target value, the motor 34 is started and stopped, the closing plate 31 is opened, and the material enters the next process. It is safe and fast, reduces the dependence on personnel, and the device has a simple structure and low cost, which meets the procurement and use needs of small and micro enterprises.
[0022] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
