Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grain transport vehicle unloading system, concretely is a kind of rotational speed detection device of grain transport vehicle unloading system. BACKGROUND

[0002] Grain transport vehicle is widely used in the transportation field of grain, feed, bulking medium, etc., which is composed of material tank and truck. The material tank is directly installed on the truck, and the facility is composed of tank body assembly, conveying system (horizontal unloading auger, vertical unloading auger, lifting unloading auger and movable unloading gate), electric system and hydraulic lifting system, etc. The three-section unloading auger of the conveying system is composed of screw conveyor, which is the main core component of the grain transport vehicle. The screw conveyor is composed of closed pipe or semi-closed pipe embedded with spiral blade, and the spiral blade is continuously welded on the rotating shaft in the center of the pipe. The spiral blade is continuously rotated by the motor drive, and the material conveying is completed in turn. The stable operation of the unloading system in the grain transport vehicle is crucial, and the normal operation of the screw conveyor can ensure the stable operation of the whole system. Once the screw conveyor stalls or jams, it will cause blockage, and further affect the operation of the upstream equipment or even cause equipment damage.

[0003] Currently, there is no corresponding detection device for the operation state of the unloading system of the grain transport vehicle, and the operation condition of the equipment is mainly judged by the operator's patrol observation. The following problems exist in the subjective judgment of the operation condition of the equipment by personnel observation alone:

[0004] 1. When the operation patrol personnel observes the discharging condition of the discharging screw conveyor outlet, if the upstream auger stalls, jams or other faults occur, there is often a delay in the reaction to the discharge port. At this time, the upstream equipment may have been jammed or seriously stuck, and if it is not handled in time, subsequent accident handling will be more time-consuming and laborious.

[0005] 2. In addition, if the three-section screw conveyor does not stall, only the rotation speed of the screw conveyor is reduced due to mechanical or material jamming fault, which causes the discharge amount to decrease. It is difficult to judge that the equipment has a jamming fault and other safety hazards only according to the discharge amount, and if it is not handled in time, it will cause greater accidents.

[0006] 3. The grain transport vehicle is suitable for the transportation of various materials, and different materials require appropriate unloading speed to avoid overloading operation of the unloading conveyor. Therefore, the operator needs to subjectively judge the load of the equipment according to experience and adjust the appropriate unloading gate opening. Improper adjustment can easily cause overloading operation of the conveyor, and further cause excessive power consumption, and seriously cause equipment damage or motor and drive burning.

[0007] The above-mentioned equipment operation safety is highly dependent on the operators, which increases the workload of the operators. During the operation of the equipment, it is necessary to pay attention to the material discharge and equipment operation at all times, and respond quickly when problems occur. If the fault occurs and the corresponding measures are not taken in time, it is easy to cause the accident to escalate and cause greater economic losses. To this end, a speed detection device for the unloading system of grain transport vehicles is proposed. Utility Model Content

The bracket structure is connected and installed to the conveyor by locking the ring seat with the shaft end bolt. The connection and installation are carried out by utilizing the structure of the conveyor itself, without much modification to the conveyor, making it convenient to use and install.

[0035] The detection mechanism is installed on the upper part of the sensor mounting bracket 3 for detecting the working rotation speed of the conveyor shaft 1.

[0038] The working principle or structural principle is as follows: During installation, select the corresponding model of the ring mounting base 5 according to the model of the grain transport vehicle, and then install the device at the corresponding detection location on the grain transport vehicle, as shown in the attached diagram. Figures 6-7 As shown in the installation diagram, during installation, first loosen and remove one bolt from the conveyor end head, generally the bolt on the top side. Then, tighten the fitting bolt to align the ring mounting seat 5 with the lower part of the sensor mounting bracket 3. Next, install the electromagnetic sensor 2 in the hole on the upper part of the sensor mounting bracket 3. During installation, first screw the lower part of the electromagnetic sensor 2 through the through hole in the upper side plate. Then, install two sets of flat nuts 6 on the upper and lower ends of the electromagnetic sensor 2 respectively using threads. Then, adjust the installation position of the electromagnetic sensor 2 and insert its lower end into the inner side of the support ring seat 7. After completion, alternately screw the flat nuts 6 to lock and limit the installation of the electromagnetic sensor 2 through double-sided clamping. After completion, use the ring mounting seat 5 to support the bracket structure on the upper part of the conveyor shaft end seat. Then, adjust the position of the mounting side seat 8 by flipping it so that the hole in the middle of the mounting side seat 8 coincides with the mounting hole of the removal bolt. Then, screw... The bolts are tightened and reset. The upper part of the bracket is limited by bolts. Then, the ring belt mounting seat 5 is locked and fixed by threaded fastening with long bolt columns and fastening end seats 10. The installation of the device is completed. The connection and installation are carried out using the structure of the conveyor itself. No major modifications to the conveyor are required. The installation is convenient. Then, the equipment wiring harness and digital display instrument are connected and installed to complete the installation. When the conveyor is working, the induction magnetic point 4 rotates with the central shaft. Each time it passes the electromagnetic sensor 2, the electromagnetic sensor 2 transmits an electrical signal to the digital display instrument. The working speed of the conveyor is converted and displayed on the digital display instrument in real time. The three unloading conveyors are equipped with this speed detection device. Once the speed of a certain section of the conveyor is abnormal, the operation of the upstream and downstream related equipment will be automatically stopped according to the interlocking relationship of the control system, and an alarm will be issued to remind the operator to take appropriate action, effectively avoiding the escalation of the accident and equipment damage.

[0039] In summary, the detection device adopts an independent working and installation structure. The electromagnetic sensor 2 is connected and installed to the conveyor shaft 1 through the sensor mounting bracket 3. The detection device is relatively independent from other electronic control systems of the grain transport vehicle, making it convenient to use and install.
