This invention discloses a surface cleaning device, belonging to the technical field of cleaning equipment. It includes a body and a floor brush. The floor brush comprises a brush body with a suction port and a clean water tank for supplying liquid, mounted on the brush body. A cleaning component is detachably installed on the front side of the brush body, and the suction port is located at the rear of the cleaning component. A wastewater tank is provided on the body. The lower end of the body is pivotally connected to the rear of the brush body via a hinge assembly. The front end of the clean water tank extends forward and at least covers the cleaning component. The rear end of the clean water tank extends backward and at least partially bypasses the hinge assembly to connect with the brush body. At least a portion of the bottom wall of the clean water tank extends continuously and smoothly from left to right, penetrating the central axis of the brush. This design eliminates the need for a connecting pipe, allowing complete drainage of the liquid in the clean water tank, increasing its capacity while simplifying its internal structure.

And the side plate of the equipment cannot be damaged.

The utility model discloses a temperature and humidity monitoring device for a vegetable greenhouse, which belongs to the technical field of vegetable planting and comprises a fixed table, four telescopic rods are fixedly mounted on the upper surface of the fixed table, a placement table is fixedly mounted at one end of each telescopic rod, and a wiping assembly is arranged on the inner wall of the placement table; according to the device, the wiping assembly is arranged, a reciprocating lead screw rotates under the action of a worm gear, a movable sleeve drives a wiping plate to move back and forth under the action of threads on the outer surface of the reciprocating lead screw, the wiping plate wipes the side wall of the monitor when moving back and forth, and therefore a sensing element is wiped; according to the monitoring device, a sensor on the monitoring device is automatically wiped while the monitoring device is lifted, so that errors of a monitoring structure caused by condensed water drops are reduced, the monitoring accuracy of the monitoring device for monitoring different heights is effectively improved, and meanwhile, the possibility that too much condensed water drops permeate into a machine to cause damage to the machine can be avoided.

The utility model discloses an auxiliary structure of a tea leaf drying rack, which relates to the technical field of tea leaf processing and comprises two main upright posts, a connecting frame is fixedly connected between the two main stand columns and is of a T-shaped structure, and the end, away from the main stand columns, of the connecting frame is fixedly connected with the auxiliary stand columns. The driving lifting frame capable of ascending and descending is arranged, and the driven lifting frames are supported through the linkage sliding rods and the supporting plates which are different in length, so that in the airing state, the driving lifting frame is located at the highest position, and the driven lifting frames can be located at the positions corresponding to the lengths of the linkage sliding rods; when the tea leaf drying device is used, the driving lifting frame descends, so that the supporting plate loses support, the driven lifting frame descends to different degrees, the bamboo sieve is convenient to take, tea leaf drying operation is greatly facilitated, and meanwhile, a relatively higher stand column can be arranged so that more tea leaves can be dried under the same occupied area.

The present invention relates to the technical field of material processing, and provides a material silo device, including a silo, a discharge port is provided at the bottom of the silo, and the material silo device also includes at least one discharge mechanism, which is provided at the bottom of the silo and connected to the silo; wherein the discharge mechanism includes: a pushing unit, which can reciprocate relative to the discharge port to push the material to the discharge port. The present invention sets a discharge mechanism at the bottom of the silo, and the discharge mechanism and the silo form a silo space, so that the bottom of the silo space has a large bottom area, ensuring that the material will not form a bridge phenomenon during the discharge process, and the material in the silo space can be continuously pushed to the discharge port by the pushing unit of the discharge mechanism, so that the viscous non-flowing material is forced out of the silo, thereby achieving the purpose of preventing the material from bridging and blocking in the silo space, and ensuring that the discharge process of the viscous non-flowing material can proceed smoothly.

The invention discloses an adjustable storage battery voltage general measurement auxiliary device, and relates to the field of storage battery data measurement tools. The invention aims to solve the problems of inconvenience in operation and potential safety hazards of the existing general measurement of the voltage of the storage battery. According to the adjustable general measurement auxiliary device for the voltage of the storage battery, the distance between probes of the meter pen is adjusted by arranging the buckle capable of freely and bidirectionally moving on the test operation rod; the first switching mechanism and the second switching mechanism are arranged to connect the test operation rod and the universal meter box, so that bidirectional measurement of storage batteries in different installation directions is realized; by arranging the LED lamp strip and the telescopic mechanism, accurate insertion and measurement of the storage battery on the inner side of the screen cabinet by the meter pen probe are realized.

The invention relates to a combined skid-mounted sewage treatment system. The system comprises a pipeline mixer, an elliptical stacked machine, an air flotation device, a sludge tank and a stacked screw machine.
