The application discloses a kind of cattle farm manure field utilization device, including including feed inlet, feed inlet connection conveying mechanism, conveying mechanism inside is provided with auger, one end of conveying mechanism is connected with extrusion flange, extrusion flange is compressed with extrusion top plate and forms compression joint, extrusion top plate sliding sleeve is connected on fixed elbow pipe, fixed elbow pipe sleeve has extrusion spring, one end of extrusion spring is fixedly connected with spring top plate, the other end of extrusion spring is connected with extrusion top plate, conveying mechanism other end is provided with transmission motor, fixed elbow pipe is fixed on liquid storage barrel, the top of liquid storage barrel is communicated with conveying mechanism by flow guide pipe, the bottom of liquid storage barrel is communicated with manure application box, metal soil shovel is set in front of manure application box, metal soil shovel one end extends to the soil inlet of manure application box, and is connected with manure application box bottom plate, the rear of manure application box is provided with soil outlet, the present application can improve the deficiency of prior art, while fertilizing protects environment, increase the efficiency of fertilization.

The utility model relates to the technical field of capacitance pointers, in particular to a combined capacitance pointer special for teaching, which comprises a grasping mechanism, a locking mechanism and an indicating mechanism, the locking mechanism is fixedly arranged on the grasping mechanism, the indicating mechanism is fixedly arranged at the top of the grasping mechanism, and the locking mechanism is fixedly arranged on the top of the indicating mechanism. The grabbing mechanism comprises a main rod, a hole, a telescopic seat, a key, a grip, friction lines, an indicator light, a hanging block and a hanging hole, the hole is formed in the top of the main rod, the telescopic seat is fixedly arranged on the main rod, the key is fixedly arranged on the telescopic seat, and the grip is fixedly arranged on the telescopic seat. According to the combined capacitance pointer special for teaching, after the combined capacitance pointer is used for a period of time, due to abrasion, the quality of the grip is reduced, at the moment, the grip and the telescopic base can be separated through the combined effect of the button, the plug pin, the limiting plate and the spring, a new grip can be replaced in time, and the use experience of a teacher is improved through the operation.
