The utility model relates to a movable kiln top cover and a communication system. The movable kiln top cover comprises a top cover body, the sealing ring is arranged right above the kiln body and is suitable for abutting against the top of the kiln body so as to seal the kiln body; the upper cover is suitable for being connected with the top cover body; a plurality of supporting pieces are arranged on the side, facing the top cover body, of the upper cover and are suitable for supporting the upper cover and the top cover body on the upper cover. A driving part is arranged between the upper cover and the top cover body and is suitable for moving the top cover body towards the direction close to or away from the kiln body, the top cover body can be moved to any kiln for use, the application range is wider, meanwhile, the kiln bodies which are not used do not need to be independently provided with the top cover body, and the cost is reduced. Therefore, the cost is effectively reduced.

The utility model belongs to the technical field of plunger pumps, and particularly relates to a plunger pump assembly which comprises a pump body, the upper surface of the pump body is fixedly communicated with an oil outlet pipe, the bottom of the pump body is fixedly communicated with an oil inlet pipe, and the inner wall of the oil outlet pipe and the inner wall of the oil inlet pipe are both fixedly connected with one-way sealing pieces. The bottom of the pump body is fixedly connected with a driving mechanism, and the surface of the driving mechanism is fixedly connected with a first disc. According to the plunger pump assembly, through cooperation of a first disc, a first rectangular hole, a cylinder, a first limiting ring, a second pump cover, a threaded barrel, a threaded column, a rotating disc, a second bearing, a second disc, a second rectangular hole, a guide column and an inclined hole, a user can rotate the rotating disc to change the distance between the cylinder and a rotating shaft, and the distance between the cylinder and the rotating shaft is changed to change the distance between the cylinder and the rotating shaft. According to the plunger pump assembly, the stroke of the plunger can be changed, and therefore the plunger pump assembly can meet different use requirements.

The present invention relates to the field of pump technology, and discloses a hydraulic control pump, a control method for the hydraulic control pump, and an excitation system. The hydraulic control pump includes: a swash plate; a plunger; a cylinder drive shaft for driving the plunger to rotate; a plurality of plunger chambers rotationally symmetrical with the axis of the cylinder drive shaft as the center; an angle adjustment mechanism for adjusting the inclination of the swash plate; each plunger chamber is equipped with an oil suction / discharge port, and each oil suction / discharge port is equipped with a waist-shaped groove corresponding thereto and arranged on the cylinder. On the one hand, there will be no relative movement between the oil suction / discharge port and the waist-shaped groove of each plunger chamber, thereby making the liquid flow change smoothly without step mutations, and the flow pulsation approaches zero. The problem of large flow pulsation caused by the relative movement of the rotating distribution plate relative to the cylinder plunger chamber in the prior art of the hydraulic control pump is solved. On the other hand, the rotating distribution plate and its driving machine are omitted, the overall structure of the device is simplified, and the production cost is greatly reduced.

The utility model relates to the technical field of agronomic fertilization, especially an agronomic quantitative fertilization device. The utility model has the advantages of: through the rotation of the reduction motor driving turntable, can pass through the connecting axle drive two connecting rods left and right reciprocating push and pull, and then reciprocating push and pull two push pistons, when the push piston is pulled, through the liquid inlet check valve and liquid inlet pipe and the fertilizer in the storage tank inside are sucked into the inside of fertilization spray cylinder, then with push piston is pushed and sprays out the water and fertilizer, through the rotation of the turntable realizes the continuous pull and spray, and the sliding stroke of the push piston in the inner wall of the fertilization spray cylinder is same, makes the spray amount equal each time, realizes quantitative spraying, through loosening the lock nut, can along the guiding strip hole sliding connecting axle's position, change the distance of connecting axle to the distance of the reduction motor output, and then change the stroke of driving connecting rod, realize the sliding stroke of push piston, realize the adjustment of single stroke liquid pumping capacity, realize the flexible adjustment of spraying capacity.

The utility model discloses a reinforcing bar bender relates to building equipment field, including the bearing car, the upper surface fixedly connected with the supporting plate of bearing car, the upper surface slidingly connected with the adjusting plate of supporting plate, the surface fixedly connected with the fixed column of supporting plate, the surface fixedly connected with the bending plate of fixed column, the inner wall slidingly connected with the locating plate of adjusting plate, the inner wall of locating plate is provided with the shaping adjusting mechanism. The utility model discloses through setting when the reinforcing bar of different bending degree that needs to bend, through making positive and negative screw rod rotation, the distance between a pair of locating plate is adjusted, changes the distance between a pair of shaping head, simultaneously can slidingly adjust the position of sleeve that sets on the slot, inserts the locating pin into corresponding slot, and the advantage of doing like this is, can change the stroke of adjusting plate close to bending plate, and the reinforcing bar of shaping different bending degree.

The anti-siphon water inlet connector comprises a connector shell and an anti-siphon assembly, the connector shell is provided with a water inlet end, a connector inner cavity and a water outlet end which are communicated with one another, the anti-siphon assembly comprises an adjusting screw rod and a sliding rod assembly, a channel is formed in the adjusting screw rod in the axial direction of the adjusting screw rod, and the sliding rod assembly is arranged in the channel. The tail end of the adjusting screw rod is provided with an air inlet communicated with the outside and the channel, the sliding rod assembly comprises a sliding piece, the sliding piece is provided with a sliding rod part and a limiting part, the sliding rod part extends into the channel from the front end of the adjusting screw rod and can move in the channel, a gas channel is reserved between the sliding rod part and the channel, and an elastic piece is arranged between the sliding rod assembly and the connector shell. The anti-siphon function and the flow adjusting function are added in the mechanical flush valve, the anti-siphon function and the flow adjusting function are integrated in the water inlet connector, and interchangeability is improved.
