The invention relates to crushing and screening equipment, in particular to particle size crushing and screening equipment for a feed. The invention aims at solving the technical problem of providingthe particle size crushing and screening equipment for the feed, which is capable of crushing the feed and indirectly performing discharging. The particle size crushing and screening equipment for thefeed comprises a bottom plate, a discharging component, a driving component, a crushing component and a collecting component, wherein the bottom plate is used for mounting the whole equipment; the discharging component is arranged on the bottom plate and is used for performing discharging in a sliding mode; the driving component is arranged on the bottom plate and is used for providing power through a motor; the crushing component is arranged on the bottom plate and is used for crushing in a rotation mode; and the collecting component is arranged on the bottom plate and is used for collectingthe feed. Through cooperation of an inclined plate and a storage box, the feed can be subjected to indirect screening and discharging, and a situation that the feed is not screened due to faster slide of the feed can be effectively prevented; and through cooperation of a push plate and a wedge-shaped plate, the feed can be automatically screened, and the manual consumption is saved.

The invention relates to an electric screw press machine which comprises a motor base, a first motor, a fry wheel which horizontally rotates a small gear, a second motor and a clutch. The outer edge of the fry wheel is gear-shaped; the small gear is meshed with the fry wheel; the first motor is connected with the small gear; and the second motor is arranged on the motor base and connected with the small gear by the clutch. By controlling the closing and the separation of the clutch and the small gear, the screw press machine can not only reasonably distribute energy, but also accelerate the rotating fry wheel in a short time, thereby causing that a sliding block has a higher hitting speed, the power of a motor is reduced, and the energy-saving effect is achieved.

The invention provides a clutch-motor composite transmission type pneumatic screw press with a bottom dead center. The pneumatic screw press comprises a machine body, a screw rod, a lower carrying bearing mounted in a groove formed in the upper plane of a cross beam mounted on the machine body, a nut, an intermediate body, a nut gland, a middle carrying bearing, a main motor, a belt pulley, a big flywheel, an upper bearing, a friction plate, a friction disk type clutch, a pneumatic cylinder body, a cap-like annular piston, a reset spring, a reversible type reciprocating driving motor, a driving gear, a small flywheel, a sliding block, a bottom dead center buffer block mounted on a machine body base and balanced hoisting cylinders vertically mounted on the two sides of the machine body, and piston rods of the balanced hoisting cylinders are connected with extension bodies of the sliding block. The clutch-motor composite transmission type pneumatic screw press has the fixed bottom dead center and is reliable and safe in operation, friendly to environment and high in hitting speed. The die contact time is short. The die service life is long. The production efficiency is high. The unbalance load resistant capacity is high. Multi-position die forging is realized. The requirements for large energy and large hitting force are met. The clutch-motor composite transmission type pneumatic screw press can be extensively applied to the forging process of hot die forging forming.

The invention relates to a table football healthy holding-pressing operation rod. The operation rod comprises a hand grip and a rod body; the hand grip comprises a fixed frame and a holding-pressing handle, symmetric sliding grooves are formed in two side edges of the inner side of the fixed frame, the holding-pressing handle is mounted in the two sliding grooves in a sliding mode, and the holding-pressing handle is connected with the fixed frame through a hit-ball spring; the rod body comprises an outer tube and an inner rod body which are coaxially sleeved; one end of the outer tube is mounted on the bottom edge of the fixed frame; a driving screw thread is arranged on the rod wall of the inner rod body, and driving tube holes are formed in the body parts of football robots; one end of the inner rod body extends out of the outer tube and is fixed onto the holding-pressing handle body, and the other end of the inner rod body penetrates through all the football robots in sequence; thefootball robots are clamped into the outer tube and can freely rotate around the inner rod body relative to the outer tube under limitation of the outer tube. The table football healthy holding-pressing operation rod can reduce damage to the wrist and prevent inclining of lumbar vertebra at the same time, and effectively improve the game experience.

The invention discloses an assembled prefabricated square culvert forming device and its manufacturing process, which comprises a base, and a plurality of vibrating devices are arranged on the inner bottom of the base, and the vibrating device includes a motor base one, and the bottom of the motor base one is connected with the The inner bottom of the base is connected and fixed, the top center of the motor seat 1 is provided with a motor 1, the side output end of the motor 1 is provided with a motor shaft 1, and the motor shaft 1 is provided on a side away from the motor There is a runner, a connecting rod is provided on the outer surface of the other side of the runner, and a plurality of casings penetrating to the top of the base are arranged on the inner top of the base, and a load-bearing column is arranged inside the casing. Beneficial effects: when the motor drives the supporting plate to reciprocate up and down, the impact force generated by the falling of the supporting plate will be absorbed by several buffer springs, and at the same time, several limit columns can limit the minimum descending height of the supporting plate to ensure the overall shape of the forming device. stability.

The invention relates to an automatic switching dual-path transmission mechanism of a punch press. A straight-through path transmission mechanism and a bypass transmission mechanism which are fixed on a case are arranged between an output shaft and a crankshaft of a servo motor; the straight-through path transmission mechanism comprises a reducer, the reducer outputs power to the crankshaft through a straight-through path connecting shaft and a straight-through path connecting sleeve; an electromagnetic gear clutch II is arranged on the straight-through path connecting shaft and the straight-through path connecting sleeve; the bypass transmission mechanism comprises a gear II, a gear I, a gear III and a gear IV; and an electromagnetic gear clutch I is arranged between the gear I and the crankshaft. The straight-through path can meet the speed requirement in a large-load punch mode, such as quick nibbling punch, and the bypass can meet the speed requirement in a small-load punch mode, such as high-speed countermark; the rated power for driving the servo motor is only about 70 percent of the conventional rated power under the same nominal pressure; and meanwhile, the energy source is saved by about 60 percent, the noise is reduced by 10 decibels. Therefore, the automatic switching dual-path transmission mechanism of the punch press can be widely applied to numerical control punching devices.
