[0057] The receiving hopper 4 is connected to the double-row roller chain 13 via a bent plate 131 welded to an outer link plate 130 of the double-row roller chain 13;

[0058] The material storage barrel structure 5 is arranged below the slide pipe 32, and the material storage barrel structure 5 includes a material storage barrel 51, a horizontal axis 52 that crosses the upper part of the material storage barrel 51, a bearing seat support beam 53 arranged on both sides of the material storage barrel 51, a sliding bearing seat 54 that fixes the horizontal axis 52 to one end of the bearing seat support beam 53, and a barrel turning arm 55; the other end of the bearing seat support beam 53 is fixed to the elevator body, specifically: the bearing seat support beam 53 is connected to the elevator body through an angle iron 57 welded to the square tube 111 The barrel flipping arm 55 is connected to one end of the horizontal axis 52 and is relatively fixed by a flat key 60; a set screw 59 is provided at the connection between the barrel flipping arm 55 and the horizontal axis 52 to fix the barrel flipping arm 55 to prevent it from sliding in the axial direction with the horizontal axis 52; an induction iron 56 is provided on one side of the lower part of the barrel flipping arm 55; a counter proximity switch 58 is provided on the bearing seat support beam 53 near the induction iron 56, and the counter proximity switch 58 is electrically connected to the time and number recorder;

[0060] The head proximity switch 33, the tail proximity switch 1224, the reduction motor 1211 and the cylinder 22 are all electrically connected to the PLC.

[0061] Furthermore, the tail sprocket tensioning device 1225 is composed of a screw rod 1226, an L-shaped plate 1227 with a through hole on one side, a No. 1 nut 1228, a No. 2 nut 1229 and a baffle plate 1230 with a through hole; the No. 2 nut 1229, the L-shaped plate 1227 and the No. 1 nut 1228 are sequentially inserted into the screw rod 1226, and the other side of the L-shaped plate 1227 is welded to the steel plate; the end of the baffle plate 1230 away from the through hole is welded to the lower part of the screw rod 1226; the connecting rod 1221 passes through the through hole on the baffle plate 1230 and is connected and fixed to the tail sprocket tensioning device 1225.

The tail sprocket tensioning device is used to properly tighten the vertically suspended double-row roller chain 13 to prevent the double-row roller chain 13 from swinging freely during operation; if it is not tightened, when it swings freely to a certain extent, it will damage the double-row roller chain 13, the receiving hopper 4 and even the elevator body. The tensioning method of the tail sprocket tensioning device is: first tighten the No. 1 nut upwards, and then tighten the No. 2 nut upwards.

[0062] Furthermore, the pneumatic sampling device 2 works under the control of PLC. When the user's production system is operating normally, a steady stream of materials will flow down from above the wear-resistant grate plate and fall from the grate gap onto the wear-resistant support plate; when the material taking frame is pushed by the cylinder to the bottom of the wear-resistant grate plate, a lot of materials will enter the material taking frame instantly or even fill it up; when the cylinder returns, the material is taken out and falls into the receiving hopper, and falls into the receiving hopper along the chute. The function of the wear-resistant grate plate: control the amount of material and guide the flow, and it can be replaced; the function of the wear-resistant support plate: support the material taking frame, wear-resistant and replaceable; the function of the joint pipe: easy to adjust the upper and lower angles during installation.

[0063] Furthermore, a horizontal shaft is welded on both sides of the storage barrel of the elevator. The horizontal shaft is inserted into the sliding bearing seat and can move freely. The sliding bearing seat is installed on the bearing seat support beam. The barrel turning arm is matched with the shaft head of one end of the horizontal shaft on the storage barrel through the shaft hole at its lower end, and is relatively fixed by a common flat key. In order to prevent the barrel turning arm from axially sliding on the horizontal shaft, it is fixed with a set screw. The barrel turning arm can be pressed Figure 8 Manually rotate about 95° in the direction shown; during rotation, the induction iron welded on the lower part of the barrel turning arm rotates together with it; when the induction iron leaves the counter proximity switch sensing head, the counter proximity switch will provide an electrical signal to the time and frequency recorder to record the sampling time (Beijing time) and the cumulative number of times at that time.

[0064] The working principle of the present invention is described below.

[0065] 1) Supply power to the electric control box and then close the circuit breaker; 2) Start the air compressor until it reaches the set pressure and stops automatically; 3) Turn the three-position switch on the electric control box door to "automatic", then the PLC programmer is powered and enters the automatic waiting state; 4) The PLC program starts, first the cylinder reciprocates to make the material frame 23 take out the cement clinker from the aggregate chute 20 at the bottom of the crusher; then the cement clinker enters the receiving hopper 4 of the elevator through the aggregate hopper 24 and the chute pipe 29; the operation of the elevator is also affected by The elevator is controlled by the PLC program. Four seconds after the hopper 4 receives the material, the elevator starts to run driven by the reduction motor 1211. A head proximity switch 33 is installed at an appropriate position on the top of the elevator. When the hopper 4 runs to the position where the sample material is just unloaded, the hopper 4 also happens to be induced by the proximity switch, so that the head proximity switch 33 provides an electrical signal to the PLC. After receiving the signal, the PLC will immediately instruct the control element to power off the reduction motor 1211 and stop, and also make the hopper 4 stop at the position where the sample material is just unloaded. Figure 2The position shown; after four seconds of stopping, the receiving hopper 4 will automatically and accurately return to the initial position. Similarly, a tail proximity switch 1224 is installed at an appropriate position at the bottom of the elevator (level with the bottom of the receiving hopper); after the receiving hopper unloads the sample material in the bucket at the head of the elevator, it must return to the receiving position at the tail of the elevator accurately; when the bottom edge of the receiving hopper passes in front of the tail proximity switch in an instant, due to the principle of electromagnetic induction, the proximity switch generates an induced electrical signal and provides this signal to the PLC. After receiving this electrical signal, the PLC immediately cuts off the power to the running reduction motor and stops it, so that the receiving hopper can accurately stop at the set position.

[0066] The above is a complete automatic sampling of the present invention. If a temporary manual sampling is required, the entire process under the above sampling state can be completed by simply rotating the three-position conversion switch to "manual". The storage capacity of the storage barrel 51 is about 20L. When the user manually extracts the sample, he needs to rotate the barrel turning arm counterclockwise about 95°. At this time, the counter proximity switch 58 installed in the appropriate position will generate induction with the induction iron at the lower end of the barrel turning arm 55 and provide an electrical signal to the time and frequency recorder. At this time, the "time and frequency recorder" records the time and frequency of this sampling. The function of the recorder is to avoid cheating.

[0067] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
