Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a drum rotation detection device for a cow bedding material system based on indirect measurement. Background Art

[0002] The cattle bedding system is a continuous production equipment that converts cattle manure into sanitary, sterile, and water-appropriate cattle bedding through solid-liquid separation and high-temperature fermentation. In recent years, it has been widely used in large-scale cattle farms. The core components of the cattle bedding system are mostly horizontal fermentation drums, and its operation needs to be tracked and detected by a special drum rotation detection device. On the one hand, it can improve the safety of the entire system. For example, when the transmission components are damaged, the reduction motor may still rotate normally, but the drum itself has stopped rotating. If the sensor detects that the drum has stopped rotating, the reduction motor can be turned off in time to avoid the expansion of the fault range and damage to other parts; on the other hand, detecting the rotation of the drum is conducive to the maintenance and preventive maintenance of the fermentation drum, which helps users to master and improve the operating process parameters of the cattle bedding system and ensure the efficient and stable operation of the cattle bedding system.

[0003] The detection components of the conventional cow bedding system drum rotation detection device are mainly composed of a counter frame fixed on the end frame of the fermentation drum and a counting sensor. The object to be detected is mainly a drum flange welded on the edge of the end face of the fermentation drum. The drum flange is made of carbon steel or stainless steel and has several long grooves. The counting sensor generally uses a proximity switch (capacitive or inductive), and its sensing surface is about 8-12mm away from the outer circumference of the drum flange. In this way, when each long groove on the outer circumference of the drum flange passes over the sensing surface of the counting sensor, the counting sensor will generate a pulse signal and send it to the control system, so that the number of drum rotations (number of pulses) and the speed of rotation (pulse frequency) can be sensed by the control system of the cow bedding system. However, this conventional drum rotation detection device has the following problems: First, the drum flange of the object to be detected is a sheet metal welded part, and its diameter is often very large (1-3m). If there are long grooves on it, the detection accuracy will be reduced if there are fewer grooves, and the cost will be relatively high if there are more grooves. In addition, due to the low dimensional accuracy of large workpieces in the sheet metal process, the circumferential runout is at least several millimeters. The general proximity switch has a detection range of 10mm. When the outer diameter error of the drum flange is large, it is easy to collide with the sensing surface of the counting sensor or move away from its sensing surface, resulting in pulse loss. Secondly, the detection device is not set in an ideal position. Whether it is set at the feed end or the discharge end of the fermentation drum, it is inevitable that the spilled materials will cover the detection device, affecting its normal use. In addition, since the counting sensor uses a capacitive or inductive proximity switch, this type of sensor is sensitive to the proximity of metal objects, and there will inevitably be some metal objects such as screwdrivers, wrenches, and maintenance and disassembly bolts and nuts in the installation site of the cattle mattress material system. If these metal objects are accidentally placed in the detection device area, it may cause the detection device to malfunction. Utility Model Content
