A material pulverizing and agitating machine comprises a rack, wherein a motor is arranged on the left side or the right side of the rack, a pulverizing and mixing box with a top opening is arranged on the rack, a feeding hopper is arranged at the top of the pulverizing and mixing box, the feeding hopper is of a conical structure with a large top and a small bottom, a discharging slotted plate is arranged at the bottom of the pulverizing and mixing box, an agitating shaft is horizontally arranged in the pulverizing and mixing box in a rotating way, a plurality of agitating rods are uniformly and vertically arranged on the agitating shaft in the axial and peripheral directions, the motor is in transmission connection with one end of the agitating shaft, the agitating rods are made by angle irons, the two side edges of the angle irons are respectively perpendicular and parallel to the axial direction of the agitating shaft, cutting edges are arranged on the outer edges of the side edges of the angle irons, perpendicular to the axial direction of the agitating shaft, and two feeding quantity regulators positioned on the same plane are arranged at the upper end opening part of the pulverizing and mixing box. The material pulverizing agitator is reasonable in design and simple in structure and has the good pulverizing and mixing effects. The feeding quantity can be regulated according to the humidity of the raw material, so that blocking phenomena are prevented.

The invention discloses a hexagonal plug-in type external groove high-pressure compact drill pipe, which comprises a male joint, a drill pipe body and a female joint connected in sequence, and a connecting pin for connecting the male joint and the female joint. The drill pipe The body has a hexagonal structure, and the male joint and the female joint are radially provided with connection holes. When the male joint and the female joint are connected, the corresponding connection holes of the male joint and the corresponding connection holes of the female joint are formed radially opposite to each other for connecting pins. Passes radially through the pin hole that connects the pin and box. The wall of the drill pipe of the present invention adopts a hexagonal body design, and the drill pipe realizes a plug-in high-pressure resistant seal. The wall of the hexagonal drill pipe body can not only keep the drill clamping and prevent sliding during the drilling process, but also improve the drill pipe’s resistance to drilling. The mixing and crushing ability of coal cinder prevents faults such as hole plugging, drill sticking, and drill sticking, and ensures the safe construction of coal mine gas drainage drilling.

The invention relates to equipment for traffic road and bridge construction, in particular to a crusher for traffic road and bridge construction with the function of filling gaps, including a machine body. There is a settling chamber on the right side. A negative pressure fan corresponding to the level of the crushing mechanism and connected to the settling chamber is installed on the right side of the machine body. A mixing chamber is provided on the inner lower part of the crushing chamber, and a rotating shaft is installed in the middle of the mixing chamber. A plurality of mixing vanes are installed in circumferential distribution, and a liquid spraying assembly is arranged on the top of the mixing chamber, and the liquid spraying assembly is connected with a liquid storage tank provided on the outer wall of the machine body. The invention has a good crushing and mixing effect on concrete materials, can be selectively humidified and mixed for standby, and also has the function of filling joints with buffer protection, which is beneficial to popularization and application.

The invention discloses a screening device for soil remediation, which comprises a screening box, the upper end of the screening box starts to have a feeding trough, the inner wall of the feeding trough is offset by an upper cover, and the inner wall of the screening box A partition is fixed, and the upper end of the partition is provided with a plurality of division grooves, the inner wall of each division groove runs through and connects the partition tube, and the circumferential side wall of each partition tube is fixed with a plurality of Scraper, the outer wall of the screening box is fixed with a bearing plate, the upper end of the bearing plate is provided with a power mechanism, and the side wall of the screening box is provided with an air outlet slot. The advantage is that the rotating tube is driven by the motor to rotate, so that the rotating tube drives the stirring plate on it to rotate, so that the stirring plate can effectively stir the soil on the top of the partition, so that the soil is stirred and pulverized, which is convenient for subsequent screening. The rotation of the pipes is opposite, and the soil between the two rotating pipes is subjected to greater shear force, so that the mixing and crushing effect of the soil is strengthened.
