The device further comprises a rack, wherein a through groove is formed on the bottom surface of the sleeve; one end of the rack across the through groove is welded with the pressing plate, and one end of the rack trough the through groove is engaged with gears. Compared with the prior art, the citrus picking device provided by the invention pushes a motor to drive the gear to move, thereby implementing fruits picking on fruit trees automatically and increasing the picking efficiency.

The invention discloses a clay dispersibility testing device. The clay dispersibility testing device comprises a fixed water head water tank, a small cone and a soil sample tube, wherein a connecting column of the small cone is communicated with the water tank through a water pipe, the soil sample tube is formed by 2-5 tube sections which are fixed to form a cylinder through a tube hoop. The invention further discloses a clay dispersibility testing method. The clay dispersibility testing method comprises the following steps of: step 1. preparing a test specimen; step 2. pushing the cone part of the small cone into one side of the test specimen, keeping the superposition of the axis of the small cone and the axis of the test specimen; step 3. forming a test specimen through hole; step 4. painting a cementing material on the other side of the test specimen so as to form a protection layer; and step 5. performing a seepage test, and determining the diameter of the test specimen through hole. The device and the method have the beneficial effects that since the detachable soil sample tube is adopted, after the test is finished, the tube hoop is detached, the soil sample tube is easily opened, the test specimen is completely taken out, and the diameter of the test specimen through hole is accurately determined. In addition, the protection layer can prevent a free face of the test specimen from being eroded by water flow during the testing process.

The invention relates to zero-load run-in equipment of a shaft coupling, belongs to the technical field of bearing processing, and the equipment can be used to effectively reduce vibration of a detection motor when the detection motor drives the shaft coupling to rotate and prevent the detection motor from damage. The equipment is characterized by comprising the detection motor, the shaft couplingto be tested is positioned in the output end of the detection motor, one end of the shaft coupling to be tested is connected with the output end of the detection motor via a universal drive shaft, the other end of the shaft coupling to be tested is rotationally connected with a tail fixed plate, the universal drive shaft is connected with the shaft coupling to be tested via a connecting shaft, the connecting shaft is rotationally arranged in a shoe plate, and the connecting shaft is arranged coaxial with an output shaft of the detection motor and can rotate along the axial direction of the connecting shaft itself. During detection, the shaft coupling to be tested vibrates, the vibration is transferred to the connecting shaft and weakened for the first time, and then transmitted to universal drive shaft and weakened again, and vibration transmitted to the detection motor finally is very low, and the detection motor is protected to largest extent.

The invention discloses a service authentication method, device and medium, which are used to improve the security of service data processing in a microservice architecture system. The business authentication method includes: receiving a business processing request, the business processing request carrying a first electronic credential and a first authentication factor required for this business processing, and the first electronic credential carrying this At least one second authentication factor required for secondary business processing, the second authentication factor is an authentication factor that has been authenticated; the first authentication factor is authenticated; and the stored public key is used to authenticate the Verify the first electronic certificate, wherein the public key is obtained from the electronic certificate center system; if it is determined that the authentication of the first authentication factor is passed and the verification of the first electronic certificate is passed, it is determined that this business processing Request authentication passed.

The invention discloses a straw harvester with a compression mechanism for agricultural machinery, comprising a main body of the harvester, a compression chamber, a crushing roller, an extrusion plate, a linkage block, a water bag and a push rod. The outer side of the main body of the harvester is arranged There is a header, the inside of the extrusion bin is provided with a movable frame, and the inside of the movable frame is connected with an extrusion plate through a shaft, the side of the fixed block is fixedly provided with a rack, and the inside of the compression bin is provided with a A guide column, the inner shaft of the compression chamber is connected with a sector gear, and a push rod is arranged under the sector gear, a water tank is arranged inside the compression chamber, and a nozzle is installed on the inner side of the compression chamber close to the extrusion chamber . The straw harvester with a compression mechanism for agricultural machinery can crush and compress the harvested straw, effectively reducing the storage space of the straw, facilitating the subsequent collection of straw, and can automatically reduce dust during use, which is practical high.

The invention discloses a cash register with a printer capable of being rapidly disassembled and assembled. The cash register with the printer capable of being assembled and disassembled quickly comprises a printer shell, a cash register shell and a shell connecting mechanism. The printer shell can slide to abut against the inner portion of the cash register shell. The shell connecting mechanism is arranged between the printer shell and the cash register shell. The shell connecting mechanism comprises a connecting piece and an elastic body. The connecting piece is rotatably connected with theprinter shell, an end of one side, close to a printer module, of the connecting piece abuts against the printer shell, the side, close to the printer shell, of the connecting piece is elastically connected with the printer shell through the elastic body, and the connecting piece is parallel to a movement direction of the printer module in an initial state. Problems that the printer is inconvenientto install and maintain and difficult to disassemble are solved.

The invention relates to the technical field of bearing machining, in particular to coupler pre-delivery bench running-in equipment, which is capable of well weakening detection motor vibration in rotation of a to-be-tested coupler driven by a detection motor to further avoid damages of the detection motor. The equipment is technically characterized by comprising the detection motor and the to-be-tested coupler positioned at an output end of the detection motor, one end of the to-be-tested coupler is connected with the output end of the detection motor through a universal shaft while the otherend is in rotational connection with a tail fixing plate, the universal shaft is connected with the to-be-tested coupler through a connection shaft which is rotationally arranged in a supporting plate, and the connection shaft is coaxial with the output shaft of the detection motor and rotates around own axis. In detection, vibration of the to-be-tested coupler is transmitted to the connection shaft to be weakened for the first time and then transmitted to the universal shaft, deflection of the universal shaft weakens vibration transmitted to the detection motor, and accordingly vibration finally transmitted to the detection motor is quite weak, and the detection motor is protected to the maximum extent.
