Abstract
A blanking cylinder with a blanking detection device comprises a blanking cylinder body which is arranged in the vertical direction. A through hole which penetrates through a cylinder wall of the blanking cylinder body is formed in the middle portion of the blanking cylinder body, a rotary shaft is arranged inside the through hole, a detection rod is arranged on the rotary shaft, the rotary shaft is connected with the middle portion of the detection rod in a rotary mode, and the rotary shaft and the detection rod then form a lever structure with the rotary shaft as a supporting point. The right end of the detection rod is placed inside the blanking cylinder body, and the left end of the detection rod is placed outside the blanking cylinder body. A touch switch is arranged at the position corresponding to the left end of the detection rod, and when the lever structure is in a state free of stress, the left end of the detection rod contacts with a sensing portion on the touch switch. When raw materials fall down inside the blanking cylinder body, the right end of the detection rod moves under the impact effect of the falling raw materials, and at the moment, the left end of the detection rod is separated from the touch switch. A signal output end of the touch switch is electrically connected with a warning device. The blanking cylinder with the blanking detection device has the advantages of being capable of monitoring wood power blanking states under the condition that no people watches over, and preventing dust from spilling.
Description
Technical field
The utility model relates to a kind of civil explosive material Fabricating machinery, relates in particular to a kind of blanking tube with blanking detection device.
Background technology
In boronation explosive manufacturing process, need first various raw materials to be sent in premixing machine to mix, wherein a kind of raw material of sending in premixing machine is exactly wood powder, for the accuracy that guarantees to prepare burden, offered inspection door in prior art on the blanking tube of wood powder, by the detect by an unaided eye blanking state of wood powder of operating personal, the visibility in order to guarantee to observe, inspection door must be enough greatly; Because wood powder is dry powdered substance, many dust of can kicking up in the process that falls if inspection door is not sealed, will cause the wood powder dust to overflow and contaminated environment and cause unnecessary waste from inspection door; If the place arranges clear covering at inspection door, after long-term the use, dust can stick on clear covering, this needs again regularly clear covering to be carried out the disassembly, cleaning operation, very bother, and extremely bother by the blanking state that the mode of observing is monitored wood powder, need to there be personnel on duty for a long time.
The utility model content
For the problem in background technology, the utility model proposes a kind of blanking tube with blanking detection device, the blanking tube that comprises vertical setting, its improvement is: be provided with the through hole that runs through the blanking tube barrel in the middle part of blanking tube, be provided with turning cylinder in through hole, be provided with test rod on turning cylinder, be rotationally connected in the middle part of turning cylinder and test rod, turning cylinder and test rod namely form the lever construction take turning cylinder as fulcrum; The test rod right-hand member is placed in blanking tube, and the test rod left end is placed in outside blanking tube; The position corresponding with the test rod left end is provided with contact switch, and lever construction is in when not stressing state, and the induction part on test rod left end and contact switch is kept in touch; When having raw material to fall in blanking tube, the test rod right-hand member is moved under the impact effect of the raw material that falls, and at this moment, the test rod left end separates with contact switch; The signal output part of contact switch and warning device electrical connection.
The principle of work of aforementioned means is: under normal circumstances, have all the time the wood powder material to fall from blanking tube in blanking tube, lever construction makes test rod left end and contact switch keep for a long time released state under the impact effect of wood powder material, and at this moment, warning device is not worked; When conveyer generation mechanical breakdown or wood powder material deficiency, fall without the wood powder material in blanking tube, lever construction makes the test rod left end contact with contact switch under Action of Gravity Field, contact switch is activated and to the warning device output signal, warning device sends alerting signal, storing amount in prompting operation person's checkout facility running state and equipment, after adopting this detecting device, the personnel that need not are on duty on the blanking tube limit, simultaneously, be used for the through hole of turning cylinder being set much smaller than the size of inspection door, can prevent effectively that dust from overflowing.
Useful technique effect of the present utility model is: can monitor wood powder blanking state in unattended situation, avoid dust to overflow.
Description of drawings
Fig. 1, structural representation of the present utility model.
The specific embodiment
A kind of blanking tube with blanking detection device, the blanking tube 1 that comprises vertical setting, its improvement is: blanking tube 1 middle part is provided with the through hole that runs through blanking tube 1 barrel, be provided with turning cylinder 2 in through hole, be provided with test rod 3 on turning cylinder 2, turning cylinder 2 is rotationally connected with test rod 3 middle parts, and turning cylinder 2 and test rod 3 namely form the lever construction take turning cylinder 2 as fulcrum; Test rod 3 right-hand members are placed in blanking tube 1, and test rod 3 left ends are placed in outside blanking tube 1; The position corresponding with test rod 3 left ends is provided with contact switch 4, and lever construction is in when not stressing state, and the induction part on test rod 3 left ends and contact switch 4 is kept in touch; When having raw material to fall in blanking tube 1, test rod 3 right-hand members are moved under the impact effect of the raw material that falls, and at this moment, test rod 3 left ends separate with contact switch 4; The signal output part of contact switch 4 and warning device 5 electrical connections.
The peripheral unit directly related with the utility model also has wood powder pay-off and premixing machine, and the wood powder pay-off is arranged at blanking tube 1 top and is communicated with blanking tube 1 upper end, and the wood powder pay-off is transported to blanking tube 1 upper end with wood powder material on even keel; Premixing machine is arranged at blanking tube 1 below and is communicated with blanking tube 1 lower end, and the wood powder material directly falls in premixing machine by blanking tube 1 is rear.
