The utility model relates to cast steel equipment technical field, concretely is a kind of vibration mechanism for continuous casting crystallizer, it includes: base, the top surface of base is fixedly connected with two side plates;Vibration frame, it is located above base and is used to install crystallizer body;Eccentric rotation drive assembly, it is provided with two, respectively install in the inner side wall of two side plates, the eccentric rotation drive assembly includes crank and connecting rod, the crank is rotatably connected with its corresponding side plate, one end of the connecting rod is hinged with the eccentric part of crank, the other end of the connecting rod is hinged with vibration frame, the rotary motion of the crank is converted into reciprocating linear motion of vibration frame by connecting rod. In the utility model, by adopting symmetrical eccentric rotation drive assembly, make vibration frame stress balance, effectively reduce eccentric load and sway, improve motion synchronism, and eccentric rotation drive assembly drives vibration frame pure mechanical drive, need not hydraulic station or complex transmission chain, system structure is simple, maintenance workload is significantly reduced.

The application discloses a servo cut-off valve group, which comprises a first valve body and a second valve body integrated on a valve seat. Both the valve bodies are provided with valve cavities, and the valve cavities are internally provided with valve spools driven by a servo motor through a screw rod. The valve bodies are provided with outer ring channels communicated with inlet and outlet of the valve seat on the side surfaces, the outer ring channels are communicated with the valve cavities through a plurality of uniformly distributed lateral flow channels, and the inner walls of the valve cavities are further provided with inner ring channels. The longitudinal flow channels at the bottoms of the two valve cavities are communicated with each other through channels in the valve seat. When the two valve spools synchronously rise above the lateral flow channels, fluid can sequentially pass through the flow channels, and the valve is opened; when the two valve spools synchronously descend to completely cover the lateral flow channels, the valve is closed. The two valve cavities are communicated at the bottoms to form a pressure balance cavity, so that the valve spools are hardly subjected to axial thrust when the valve is closed, and high pressure is converted into sealing force in the radial direction of the valve spools, thereby fundamentally solving the high pressure leakage problem of traditional cut-off valves, and the application is especially suitable for high pressure equipment such as filter presses.

The invention discloses a differential clamping vibration type walnut picking machine, which relates to the technical field of agricultural machinery, and comprises a walking mechanism for driving the whole machine to move, a transmission system for realizing the advancing, retreating and steering movement of the walking mechanism, and a truss rotating mechanism for realizing the left and right 90-degree free rotating movement of a truss operation platform, the truss operation platform is fixedly connected with the truss rotation mechanism, the diesel engine provides power for the whole machine, the suspension arm structure system is used for achieving suspension supporting and space positioning of the vibration excitation device, and the vibration excitation device is used for achieving vibration on a tree trunk. While ensuring reliable harvesting of fruits, the device has the advantages of compact structure, cost and installation space saving, adjustable excitation intensity, stable operation, reduction of damage to branches and fruits, reduction of machine moving alignment preparation time and the like, and the continuous operation capability and the picking efficiency are improved.

The utility model belongs to capstan technology field provides a kind of electric capstan, comprising: support frame, rotatably arranged with drum thereon;Driving part, it is set on support frame;Reduction assembly, it includes oppositely arranged first reduction part and second reduction part, and connecting the shaft between first reduction part and second reduction part, first reduction part is arranged in the one end of drum along the axial direction, and is connected between the output end of driving part and shaft, second reduction part is arranged in the other end of drum along the axial direction;Transmission part, it is movably arranged between second reduction part and drum.Compared with prior art, the utility model is through setting reduction part in the both ends of drum and being connected by shaft, realizes bilateral power input, improves the stress uniformity of drum, improves structural stability and service life;At the same time, through movable transmission part, the switching of electric and manual mode is realized, and the rope can be quickly released in manual mode, and electric energy is saved.

This invention discloses a crusher crushing plate stroke adjustment transmission device, including a frame, a rotor assembly, a crushing plate, and a stroke transmission assembly. The crushing plate includes an upper crushing section and a lower crushing section distributed along the material flow direction, which are connected by a hinge structure. The stroke transmission assembly includes a drive motor, a worm gear reducer, and an adjusting screw. The adjusting screw passes through the frame and is connected to the crushing plate through a ball-end self-aligning connection structure. A guide floating sleeve is provided between the adjusting screw and the frame. When the crushing plate undergoes an angle change during operation, the ball end can generate relative rotation within the self-aligning seat, thereby adapting to and compensating for the angle change. Through the synergistic effect of the above structures, the off-center load on the adjusting screw can be reduced during crushing plate adjustment, improving the operational stability of the adjustment mechanism under impact conditions.
