Description

Technical Field

[0001] The utility model relates to the technical field of spiral conveying equipment for feed processing, in particular to a spiral extrusion conveying equipment for raw materials in dog food processing. Background Art

[0002] In dog food production, meat raw materials need to be dehydrated and defatted before being pressed and crushed. The obtained feed after the above treatment has a higher protein content. In the large-scale production of feed in factories, the meat raw materials need to be transported. This spiral extrusion conveying equipment for raw materials in dog food processing is used to perform spiral extrusion conveying on the crushed meat raw materials during dog food processing.

[0003] For example, in the patent with the authorization announcement number CN203269117U and the name "Screw Conveyor", it includes a storage tank, a flange box and a screw barrel. The storage tank is located above the flange box, and the flange box and the screw barrel are connected through a flange box lower cover. The installation holes for connecting the flange box and the flange box lower cover are set as adjustable slot holes.

[0004] Similar to the above application, the existing spiral extrusion conveying equipment all performs spiral extrusion conveying on materials by setting a feed bin in cooperation with a screw conveyor. When the screw conveyor is performing spiral conveying on materials, when the discharge interface of the screw conveyor becomes stuck or blocked, if it is not discovered in time, it will cause an increase in the load of the motor driving the screw conveyor, easily leading to equipment failures and leakage of the conveying pipeline due to the extrusion of the conveying pressure. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the problems in the prior art that when the screw conveyor is performing spiral conveying on materials, when the discharge interface of the screw conveyor becomes stuck or blocked, if it is not discovered in time, it will cause an increase in the load of the motor driving the screw conveyor, easily leading to equipment failures and leakage of the conveying pipeline due to the extrusion of the conveying pressure. A spiral extrusion conveying equipment for raw materials in dog food processing is provided. By setting a conveying adjustment mechanism, when the discharge interface becomes blocked, at this time, the screw conveyor passively drives the conveying adjustment mechanism, and the conveying adjustment mechanism drives the feeding baffle to slide and adjust through a connecting rod assembly. By reducing or closing the feeding channel of the feeding interface through the feeding baffle, the power of the screw conveyor is reduced, and the conveying pressure of the blocked screw conveyor is automatically reduced, avoiding an increase in the load of the motor driving the screw conveyor and causing failures and leakage of the conveying pipeline due to the extrusion of the conveying pressure.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] The utility model discloses a raw material spiral extrusion conveying device for dog food processing, comprising a spiral conveyor and a raw material bin, wherein the spiral conveyor is arranged at the bottom of the raw material bin, and the bottom of the raw material bin is connected with the spiral conveyor through a feeding interface, that is, the dog food raw material stored in the raw material bin is fed into the spiral conveyor through the feeding interface, and finally the raw material is spirally extruded and conveyed by the spiral conveyor;

[0008] A feed baffle is slidably arranged in the feed interface, and the feed baffle is adjusted by sliding in the feed interface to realize opening and closing adjustment of the feed channel of the feed interface. The front end of the screw conveyor is connected to the discharge interface, and a conveying adjustment mechanism is arranged on the discharge interface, and the conveying adjustment mechanism is transmission-connected to the feed baffle through a connecting rod assembly;

[0009] When the discharge interface is blocked, the passively driven conveying adjustment mechanism drives the feed baffle to adjust the size of the discharge opening of the feed interface through the connecting rod assembly.

[0010] Specifically, when the screw conveyor is conveying raw materials, when the discharge interface is blocked, the screw conveyor passively drives the conveying adjustment mechanism, and the conveying adjustment mechanism drives the feed baffle to slide and adjust through the connecting rod assembly. The feed baffle reduces or closes the feed channel of the feed interface, thereby reducing the power to the screw conveyor, and automatically reducing the conveying pressure of the blocked screw conveyor, thereby avoiding the increase of the load on the motor driving the screw conveyor and the occurrence of failures and leakage in the conveying pipeline due to the extrusion of the conveying pressure.

[0011] Preferably, the conveying and adjusting mechanism includes a pressure transmission tube arranged on the discharge interface, and the pressure transmission tube is connected to the inside of the discharge interface, an adjusting piston rod is slidably embedded in the pressure transmission tube, a supporting spring is arranged between the adjusting piston rod and the pressure transmission tube, and the elastic force of the supporting spring is used to drive the adjusting piston rod to move toward the inside of the pressure transmission tube, an adjusting cross frame is fixed to the top end of the adjusting piston rod, the connecting rod assembly includes a rotating connecting frame rotatably connected to the end of the adjusting cross frame, the bottom end of the rotating connecting frame is rotatably connected to a sliding adjusting frame, the sliding adjusting frame is horizontally slidably arranged on the outside of the feed interface, optionally, a strip guide rail is arranged on the outside of the feed interface, the sliding adjusting frame is horizontally slidably embedded on the strip guide rail, and the end of the sliding adjusting frame is connected to the feed baffle. Specifically, when the discharge interface 4 is blocked, the raw materials transported at this time flow into the pressure transmission tube and push the adjusting piston rod to compress the support spring and move up. At this time, the adjusting cross frame at the top of the adjusting piston rod moves up synchronously, and the adjusting cross frame drives the sliding adjusting frame to slide and translate through the rotating connecting frame, thereby pulling the feed baffle to slide and adjust through the sliding adjusting frame to reduce or close the feed channel of the feed interface.

[0012] Preferably, a U-shaped frame is fixedly arranged on the discharge interface. A strip-shaped limiting notch is formed in the U-shaped frame, and two ends of the adjusting cross frame are slidably embedded in the strip-shaped limiting notch. Specifically, by fixedly arranging the U-shaped frame on the discharge interface and slidably embedding two ends of the adjusting cross frame in the strip-shaped limiting notch on the U-shaped frame, the lifting and moving of the adjusting piston rod are limited and supported, preventing the traction force of the sliding adjusting frame from acting on the adjusting piston rod in the reverse direction and affecting the sealing effect of the adjusting piston rod, and improving the stability of the adjusting piston rod to adapt to pressure adjustment.

[0013] Preferably, a bearing seat is arranged at the bottom of the screw conveyor. Support frames are arranged at the corner positions on the periphery of the raw material bin, and the bottom ends of the support frames are fixed to the bearing seat. Moving rollers are installed at the bottom of the bearing seat. By integrally installing the screw conveyor and the raw material bin on the bearing seat and installing moving rollers at the bottom of the bearing seat, the movement and adjustment of the raw material screw extrusion and conveying equipment for dog food processing are made more convenient.

[0014] Preferably, a driving motor is arranged at the tail end of the screw conveyor, and the driving motor is in transmission connection with the screw conveyor through a coupling.

[0016] Secondly, by fixedly arranging a U-shaped frame on the discharge interface and slidably embedding two ends of the adjusting cross frame in the strip-shaped limiting notch on the U-shaped frame, the lifting and moving of the adjusting piston rod are limited and supported, preventing the traction force of the sliding adjusting frame from acting on the adjusting piston rod in the reverse direction and affecting the sealing effect of the adjusting piston rod, and improving the stability of the adjusting piston rod to adapt to pressure adjustment.

A raw material screw extrusion and conveying device for dog food processing is provided. By setting a conveying and adjusting mechanism, when the discharging interface becomes blocked, the screw conveyor passively drives the conveying and adjusting mechanism at this time. The conveying and adjusting mechanism drives the feeding baffle to slide and adjust through the connecting rod assembly, and reduces or closes the feeding channel of the feeding interface through the feeding baffle, reducing the power of the screw conveyor, realizing the automatic reduction of the conveying pressure of the blocked screw conveyor, and avoiding the increase in the load of the motor driving the screw conveyor resulting in failures and the leakage of the conveying pipeline due to the extrusion of the conveying pressure. The raw material screw extrusion and conveying device for dog food processing in the present utility model is not limited to the descriptions of the following embodiments.

[0025] Specifically, when the screw conveyor 2 is conveying raw materials, when the discharge interface 4 is blocked, the screw conveyor 2 passively drives the conveying adjustment mechanism 5, and the conveying adjustment mechanism 5 drives the feed baffle 32 to slide and adjust through the connecting rod assembly 6. The feed baffle 32 reduces or closes the feed channel of the feed interface 31, thereby reducing the power to the screw conveyor 2, and automatically reducing the conveying pressure of the blocked screw conveyor 2, thereby avoiding the increase of the load on the motor driving the screw conveyor and the occurrence of failure and leakage of the conveying pipeline due to the squeezing of the conveying pressure.
