Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in the structural attached figures 1-4, the automatic stone powder crushing and supplying feeding bin of the mixing station comprises a bin body 1, wherein the upper side of the bin body is provided with a feeding hole, the lower side of the bin body is provided with a contraction type discharging hole, a crankshaft 2 and a steel chisel 3 are arranged above the discharging hole in the bin body, the feeding bin is also provided with a vibrating device, the crankshaft 2 comprises straight shaft rods 21 which are coaxially arranged at two ends, and a wavy curved rod 22 is arranged between the two straight shaft rods 21; straight shaft rods 21 at two ends of the crankshaft 2 are arranged on the bin walls at two opposite sides of the bin body 1 through bearings, a steel chisel 3 is vertically and fixedly connected at the eccentric peak of a curved rod 22, the steel chisel 3 is a high-strength steel bar with the diameter of 2cm, and the end of the steel chisel 3 is pointed; one end of the crankshaft 2, which extends out of the two ends of the bin body, is connected with a motor 4 through a straight shaft 21, and the motor 4 is fixedly connected with the outer wall of the upper bin; the vibrating device 5 is arranged on the outer wall of the discharge hole; a contact type material level sensor 6 is further installed below the discharge port, a circuit of the material level sensor 6 is connected with an operation chamber of the mixing station, and a light sensation alarm lamp and a sound sensation alarm whistle are configured in the operation chamber.

The utility model discloses the blowing condition of bin mouth ejection of compact to conveyer belt 7 is continuously monitored to material level inductor 6 in the mix station production process, and the discharge gate material level changes when the feed bin appears blockking up, conveys respectively to the control circuit of motor 4 control circuit and vibrator 5 behind the material level inductor 6 monitoring signal, makes 2 and 3 motions of drill rod of bent axle, 4 vibrations of bulkhead vibrator take place and alarm device.

Specifically, the drill rod 3 may be welded to the curved bar 22 as shown in fig. 6(a), or may be connected to the curved bar 22 through the shaft tube 31 as shown in fig. 6 (b).

Specifically, the utility model relates to a wavy curved bar 22 is the crooked curve that imitates the sine wave shape. It is also possible that the knee lever is offset to a greater extent towards the downward eccentric point than towards the upward eccentric point.

The structure of fixing the steel rod at the eccentric point can form two circumferential loose tracks as shown in fig. 5.

The crankshaft is driven to rotate by the motor 4, and the eccentric rotation of the crankshaft realizes the vertical pulling and inserting of the drill steel 3 at the eccentric point of the crankshaft or the propping at the material opening, so that the blockage at the upper part of the material outlet is loosened.

The bin wall vibrating device also receives the blocking signal, so that a vibrating mode is started, and the vibrating force is transmitted to the blocking materials measured in the bin wall through the bin wall, so that the stone materials blocked by the discharge port are loosened and dredged.

The alarm lamp is divided into a green lamp, a yellow lamp and a red lamp. The yellow warning lamp is turned on when the blockage signal is received for the first time, and the warning whistle is turned on simultaneously to intermittently whistle to warn an operator, so that the operator is informed that the bin is blocked and needs to be observed in time.

After the dredging operation in the waiting bin is carried out for a while (generally, 1min-2min is set), if the material level sensor still does not sense the discharge, the sensor transmits a signal to the alarm, the warning light becomes red, the alarm whistle is changed into a continuous whistle to inform an operator that the bin is empty or the blanking cannot be carried out due to the fault, and the operation needs to be stopped for inspection in time.

Two pine material devices are opened the back and are carried out the mediation to the jam material, and the normal ejection of compact of discharge gate, material level inductor monitoring material level initiate shut-off signal to two pine material devices and alarm device after being normal. The loosening device stops working after receiving the signal, and the alarm device stops intermittent whistling and the alarm lamp turns green after receiving the signal.

The device has the advantages that: 1. the function of automatically monitoring discharging and supplying in the material blocking process of the material bin is realized; 2. the problem of feed bin discharge gate putty shut down the mediation is avoided, production efficiency has been improved, manufacturing cost has been reduced. 3. The problem of construction of material breakage in the production process is solved, and the production quality control is improved.
