[0002] Rake dryer is a dryer suitable for heating and drying slurry, paste and powder materials. After drying by the rake dryer, the materials can be directly packaged without crushing.

[0003] At present, the Chinese utility model patent with publication number CN220103626U has published a uniformly heated stirring vacuum rake dryer, including a mounting base, a dryer body and a limiting disc, the upper surface of the mounting base is provided with a fixing frame, and the dryer body is installed in the cavity of the fixing frame, a feed pipe is installed through the upper surface of the dryer body, and a driving motor is fixedly connected to the side surface of the dryer body, a stirring shaft is connected in the cavity of the dryer body, and one end of the stirring shaft is fixedly connected to the output end of the driving motor, and a stirring claw is fixed on the surface of the stirring shaft. The equipment has the advantages of increasing the contact area between the material and the inner wall of the dryer body, and improving the uniformity of heating and drying.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: since the stirring claws are arranged at intervals and only rotate around the stirring shaft, it is difficult to remove the material from the dryer body after heating, and the type of material cannot be frequently changed, resulting in poor production efficiency. Utility Model Content

[0005] In order to facilitate the removal of materials in the dryer body, the present application provides a rake dryer with convenient material discharge.

[0006] The present application provides a rake dryer with convenient material discharge, which adopts the following technical solution:

[0007] A rake dryer with convenient discharge comprises a dryer body, a rotating shaft, a plurality of rotating paddles, a push plate, a driving member and a pushing assembly. A cavity for drying materials is provided in the dryer body, a discharge port is provided in the dryer body, the discharge port is communicated with the cavity, the rotating shaft is rotatably connected to the dryer body, the driving member is used to drive the rotating shaft to rotate, the push plate is arranged on the rotating paddle away from the discharge port, the push plate abuts against the inner side wall of the cavity, and the pushing assembly is used to change the distance between the plurality of rotating paddles.

[0008] By adopting the above technical solution, during the process of drying materials in the dryer body, the driving member drives the rotating shaft to rotate, the rotating shaft drives the rotating paddle to rotate, and the rotating paddle drives the materials to turn over in the cavity for drying. When the materials are dried, the staff can use the pushing component, which changes the distance between the rotating paddles until the adjacent rotating paddles abut against each other, and the push plate changes the volume of the cavity that can accommodate the materials, so that the materials can contact the rotating paddles as much as possible. After that, the staff starts the driving member again, and the driving member drives the rotating paddle to rotate. Since the rotating paddles abut against each other at this time, the materials will be moved toward the discharge port by the rotating paddles until the materials in the cavity are discharged from the discharge port. Finally, the staff starts the pushing component again, and the pushing component drives the distance between the plurality of rotating paddles to increase, and makes the push plate away from the discharge port, so as to facilitate the drying of subsequent materials.

[0009] Optionally, the rotating shaft is in the shape of a square rod, and the rotating paddle includes a slip ring and a plurality of blades, the slip ring is slidably connected to the rotating shaft, the plurality of blades are distributed along the axis of the slip ring, and one end of the blade is arranged on the side wall of the slip ring.

[0010] By adopting the above technical solution, the rotating shaft is in the shape of a square rod, and the sliding ring is slidably connected to the square rod, so that the rotating ring rotates with the rotating shaft. The rotating shaft does not need to be provided with a sliding groove for the sliding of the sliding ring, which reduces the situation where the material to be dried falls into the sliding groove and causes the sliding ring to be unable to move, thereby improving the service life of the rotating paddle.

[0011] Optionally, the pushing assembly includes a pushing cylinder, a rotating ring and a plurality of linkage parts, the rotating ring is coaxially arranged with the push plate, the rotating ring is rotatably connected to the push plate, the cylinder body of the pushing cylinder is arranged on the dryer body, one end of the pushing cylinder piston rod penetrates into the cavity, one end of the pushing cylinder piston rod is arranged on the rotating ring, and the plurality of linkage parts are arranged between adjacent rotating paddles, and the linkage parts are used to connect two adjacent rotating paddles.

[0012] By adopting the above technical solution, the pushing cylinder drives the push plate to move at a fast speed, which can improve the discharge speed of the dryer body. The push plate needs to rotate simultaneously with the corresponding rotating paddle, so the push plate will rotate relative to the dryer body, and the push plate will rotate relative to the rotating ring. The pushing cylinder does not need to rotate, and the pushing component structure is simple and reasonable.

[0013] Optionally, the linkage includes a first connecting rod, a second connecting rod and a third connecting rod, one end of the first connecting rod is rotatably connected to the rotating paddle, the other end of the second connecting rod is rotatably connected to an adjacent rotating paddle, and both ends of the third connecting rod are respectively rotatably connected to the first connecting rod and the second connecting rod.

[0014] By adopting the above technical solution, when the push cylinder drives the push plate to move toward the discharge port, the push plate will drive a number of rotating paddles to approach each other until adjacent rotating paddles abut against each other, and the first connecting rod is parallel to the second connecting rod through the third connecting rod. At this time, the material can be discharged. When the material completes the discharge port, the piston rod of the push cylinder retracts, and the push plate moves away from the discharge port. Driven by the first connecting rod and the second connecting rod, the rotating paddles move away from each other until the first connecting rod, the second connecting rod and the third connecting rod are in the same straight line. At this time, the distances between the rotating paddles are the same, and it is ensured that the position of the rotating paddle relative to the rotating shaft remains unchanged during the drying process of the dryer.

[0015] Optionally, both end surfaces of the rotating ring are provided with grooves, and one end of the first connecting rod and one end of the second connecting rod corresponding to the rotating ring are respectively arranged in the two grooves.

[0016] By adopting the above technical solution, when adjacent rotating paddles abut against each other, the length direction of the first connecting rod is parallel to the radial direction of the rotating ring, and the length direction of the second connecting rod is parallel to the radial direction of the rotating ring. Since one end of the first connecting rod and one end of the second connecting rod are respectively located in the two grooves of the rotating ring, adjacent rotating paddles can abut against each other, so that during the discharging process, the rotation of the rotating paddles can better bring the material to the discharge port.

[0017] Optionally, an ejection assembly is provided on the rotating shaft, and the ejection assembly includes an ejection bar, a plurality of ejection blocks and a sliding member. The length direction of the ejection bar is parallel to the length direction of the rotating shaft. The ejection bar is slidably connected to the rotating shaft along the direction from the rotating shaft to the third connecting rod. The plurality of ejection blocks correspond one-to-one to the plurality of third connecting rods, and the sliding member is used to drive the ejection bar to move.

[0018] By adopting the above technical solution, when the first connecting rod, the second connecting rod and the third connecting rod are in the same straight line, when the pushing cylinder drives the push plate to move toward the discharge port, the rotating paddle will be unable to move, and the staff can first use the sliding part, the sliding part drives the ejection bar to move, the ejection bar will drive several ejection blocks to move, the ejection blocks will abut against the third connecting rod, and the third connecting rod will move in the direction away from the rotating axis. At this time, the staff will start the pushing cylinder again, and the pushing cylinder will drive the push plate to move. At this time, the first connecting rod and the second connecting rod can approach each other until they are parallel to each other, and adjacent rotating paddles can abut against each other.

[0019] Optionally, the sliding member includes a rotating motor and a push rod, the length direction of the push rod is parallel to the length direction of the rotating shaft, the cross-section of the push rod is elliptical, the side wall of the push rod abuts against the ejection strip, the rotating motor is arranged on one end of the rotating shaft, and one end of the push rod is arranged on the rotating motor.

[0020] By adopting the above technical solution, the rotating motor drives the ejector rod to rotate. Since the cross-section of the ejector rod is elliptical, and the ellipse has a long side and a short side, the ejector bar can move under the rotation of the ejector rod, and the ejector bar will drive a number of ejector blocks to move, and the ejector blocks can drive the third connecting rod to move in the direction away from the rotating axis. After the first connecting rod is not parallel to the second connecting rod, the pushing cylinder can drive the push plate to move, and the push plate can drive a number of rotating paddles to move on the rotating axis.

[0021] Optionally, the driving component includes a driving motor, a first synchronous wheel, a second synchronous wheel and a synchronous belt, the first synchronous wheel is arranged on one end of the rotating shaft, the driving motor is arranged on the dryer body, the second synchronous wheel is arranged on the output shaft of the driving motor, and the synchronous belt is sleeved on the first synchronous wheel and the second synchronous wheel.

[0022] By adopting the above technical solution, the driving motor drives the second synchronous wheel to rotate, the second synchronous wheel drives the first synchronous wheel to rotate through the synchronous belt, and the first synchronous wheel drives the rotating shaft to rotate. The driving part has a simple structure and is easy to operate by the staff.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The push plate can move on the rotating shaft, and the pushing assembly can drive several rotating paddles to approach each other. The push plate can reduce the bearing space of the cavity inside the dryer body, which is convenient for materials to gather, and make adjacent rotating paddles abut against each other. The rotation of adjacent rotating paddles is convenient for bringing the dried materials to the discharge port;

[0025] 2. The linkage can ensure that the distance between adjacent rotating paddles remains consistent when the push plate is far away from the discharge port;

[0026] 3. The sliding member facilitates the first connecting rod and the second connecting rod, which are originally on the same straight line, to rotate relative to the rotating propeller. BRIEF DESCRIPTION OF THE DRAWINGS
