The life prone type supporting chair comprises a cushion body, a suspension portion and a supporting portion, wherein the cushion body is fixedly arranged on the supporting portion through the suspension portion; the cushion body comprises a base cushion and a supporting cushion arranged at the front end of the base cushion, and the supporting cushion is used for supporting the manubrium sterni of a user to make the neck of the user hang; and the suspension portion mainly comprises main suspension strings and balancing suspension strings, the main suspension strings are used for jacking up the inner sides of shoulders of the user, and the balancing suspension rings are used for suspending the body of the user after the inner sides of the shoulders are jacked up. The lie prone type supporting chair can be combined with a table body in order to effectively mitigate the fatigue degree of the cervical vertebra and the lumbar vertebra on the premise of guaranteeing the office efficiency.

The invention relates to a head-mounted headphone testing robot for an embedded computer. The robot comprises a bottom plate, a mounting fixed frame is mounted at the bottom plate, a fixed adjusting cylinder is arranged on the inner wall of the mounting fixed frame, the top end of the fixed adjusting cylinder is mounted on a fixed adjusting plate through a flange, two clamp testing devices are arranged on the fixed adjusting plate in a rotary connecting way, a work placing rack is mounted on the mounting fixed frame, and a work limiting hole is formed on the side wall of the work placing rack,a work execution device is arranged in the work limiting hole, and limiting operation devices are symmetrically arranged on the sidewalls of the work placing rack. The problems that the bending testing on the head-mounted headphone is required in the production testing process of the existing head-mounted headphone, the quality of the head-mounted headphone cannot be ensured since the artificialbending testing on the head-mounted headphone is imprecise, and the expected testing effect cannot be achieved since the artificial testing method is simple are solved.

The invention relates to a waste acid recycling process and a matching device thereof, belonging to the technical field of water treatment. The waste acid recycling process comprises the following steps of: carrying out pre-treatment on waste acid by virtue of ultrafiltration membrane air flotation; vertically mounting an ultrafiltration membrane assembly, and then feeding the waste acid from thelower part of the ultrafiltration membrane assembly by utilizing a gas-liquid hybrid power device to carry out ultrafiltration membrane air flotation purification treatment; and recycling the waste acid by adopting air flotation dialysis after the pre-treatment, thus having the advantages of low energy consumption, strong operability, good effluent quality, small waste acid recycling volume, highconcentration and the like. The matching device comprises a waste acid tank and a pre-treatment ultrafiltration membrane assembly which is vertically arranged, wherein the pre-treatment ultrafiltration membrane assembly is connected with a penetrating fluid discharge pipe, the lower part of the pre-treatment ultrafiltration membrane assembly is connected with a feeding pipe, the upper part of thepre-treatment ultrafiltration membrane assembly is connected with a concentrated solution discharge pipe, the other end of the feeding pipe of the pre-treatment ultrafiltration membrane assembly is communicated with the waste acid tank, and the feeding pipe is provided with the gas-liquid hybrid power device. The device has a compact structure, is stable in operation and simple in management and is applicable to recycling of multiple waste acids.

The invention discloses a shield tunneling machine mortar stop sealing device which comprises a body. Supporting devices are arranged on the side walls of the upper end and the lower end of the body,a sealing device is connected between the two supporting devices and comprises two first sealing rings, two second sealing rings and third sealing rings, the supporting devices comprise mounting grooves formed in the side walls of the body, fixing grooves are formed in the inner bottoms of the mounting grooves, the inner bottoms of the fixing grooves are fixedly connected with a shell, a hollow cavity is formed in the shell, the inner side wall of the hollow cavity is fixedly connected with a motor, the tail end of an output shaft of the motor is fixedly connected with a driving wheel, a fixing rod is arranged in the hollow cavity, and the outer side wall of the fixing rod is fixedly connected with a driven wheel engaged with the driving wheel. The shield tunneling machine mortar stop sealing device is reasonable in structural design, substantial consumption of mortar can be prevented, ground surface settlement is reduced, and the working efficiency of a shield tunneling machine is improved.

The invention relates to the technical field of agricultural machines, and discloses a conical spiral cavitating device. The conical spiral cavitating device comprises a cavitating assembly and a connecting assembly and is characterized in that the cavitating assembly is composed of a center shaft, a circular-truncated-cone-shaped spiral blade, a cavitating cone and a reaming cutter, an external thread is arranged at one end of the center shaft, the other end of the center shaft is connected with the cavitating cone, the circular-truncated-cone-shaped spiral blade is arranged on the center shaft in a sleeving mode through an inner hole and is fixedly welded, and then the circular-truncated-cone-shaped spiral blade, the center shaft and the cavitating cone are connected into a whole; the connecting assembly is composed of a circular-truncated-cone-shaped flange plate, a flange plate outer boss, a flange plate inner boss and breast boards, the face, provided with the outer boss, of the circular-truncated-cone-shaped flange plate is a plane, the face, provided with the inner boss, of the circular-truncated-cone-shaped flange plate is a conical surface, and the four breast boards are uniformly distributed on the conical surface in the radial direction. The conical spiral cavitating device has the advantages that the cavity hole wall is not prone to collapsing, cavitating quality is high, by means of the circular-truncated-cone-shaped spiral blade, work friction resistance is small, power consumption is low, the cavitating assembly which is a quick-wear part is easy to disassemble, and therefore cost of a whole machine is greatly reduced.

The invention relates to a medical healthcare medicinal material picking tool. The medical healthcare medicinal material picking tool comprises a bottom plate, wherein the lower end of the bottom plate is provided with lifting air cylinders which are uniformly distributed along the circumferential direction of the bottom plate, the bottom end of each lifting air cylinder is installed on an annularpicking plate by virtue of a flange, a picking execution apparatus is installed on the annular picking plate, flexible skirt edges are uniformly arranged on the lower end of the bottom plate along the circumferential direction, and the lower end of each flexible skirt edge is installed on the picking execution apparatus. By adopting the medical healthcare medicinal material picking tool, the problems in the existing lucid ganoderma picking process that the lucid ganoderma needs to be manually picked, people need to repeatedly bend down in the manual picking process, the human body is easy toharm, the lucid ganoderma is easy to damage due to the carelessness due to the long-time repeated operation and heavy labor operation, the lucid ganoderma is easy for attracting creatures such as poisonous insects, poisonous snakes and people is easy to attack by parasitic poisonous substances when picking the lucid ganoderma can be solved.
