[0004] The spherical dryer of this structure has a main body including a spherical casing composed of a spherical outer shell, a heat insulation layer, a heating layer, and a spherical inner shell stacked in sequence. That is, the spherical casing is an integral whole. The stirring blades are located inside the spherical casing and need to be fed into the spherical casing through the discharge port for assembly. Due to the narrow space, the stirring blades are inconvenient to install, resulting in inconvenience in the installation of the spherical dryer. Moreover, during cleaning, the cleaning component cannot clean the stirring blades well, resulting in inconvenience in cleaning the spherical dryer. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems existing in the prior art, and to propose a switch cover structure for a spherical dryer, and to solve the technical problem of how to make the spherical dryer easy to assemble and clean.

[0006] The objectives of the utility model can be achieved through the following technical solutions: a switch cover structure of a spherical dryer, the spherical dryer includes a frame, characterized in that the spherical dryer also includes an upper tank body fixedly connected to the frame and having a hemispherical shape and a lower tank body located in the frame and having a hemispherical shape, the switch cover structure includes an upper hinge seat fixedly connected to the upper tank body, a lower hinge seat fixedly connected to the lower tank body and a first driver arranged in the frame, the upper hinge seat and the lower hinge seat are hingedly connected by a rotating shaft, the rotating shaft is fixedly connected to the lower hinge seat, and the first driver can drive the lower tank body to rotate through the rotating shaft so that the open end of the lower tank body and the open end of the upper tank body are in contact with each other.

[0007] The upper tank body and the lower tank body are two independent parts. The upper tank body is hinged to the lower tank body through an upper hinge seat, a lower hinge seat and a rotating shaft. The rotating shaft is fixedly connected to the lower hinge seat. When closing the lid, the first driver drives the rotating shaft to rotate, thereby driving the lower hinge seat to rotate, causing the lower tank body to rotate around the rotating shaft so that the open end of the lower tank body and the open end of the upper tank body are aligned, thereby completing the closing action of the upper and lower tank bodies. When opening the lid, the first driver drives the lower tank body to rotate around the rotating shaft in the opposite direction so that the open end of the lower tank body moves away from the open end of the upper tank body, thereby completing the opening action of the upper and lower tank bodies. When assembling, repairing or cleaning the parts inside the tank body, since the upper and lower tank bodies can be opened with the lids opened, the spherical dryer is easy to assemble and clean. During production and processing, the upper and lower tank bodies can be closed.

[0008] In the aforementioned spherical dryer switch cover structure, one end of the rotating shaft extends beyond the lower hinged seat and is fixedly connected to a rotating frame. The output shaft of the first driver is hingedly connected to the rotating frame, and the tail end of the first driver is hingedly connected to the frame. Both ends of the first driver are hinged to prevent the first driver from getting stuck, allowing the first driver to drive the lower tank to rotate. The rotating shaft is fixedly connected to the lower hinged seat, and the rotating frame is fixedly connected to the rotating shaft, allowing the first driver to drive the lower tank to rotate about the rotating shaft. A bearing can be provided between the rotating shaft and the upper hinged seat to ensure smooth rotation of the lower tank.

[0009] In the above-mentioned switch cover structure of the spherical dryer, the switch cover structure also includes a rotatable annular chuck sleeved on the open end of the upper tank body and a second driver arranged in the frame, a plurality of upper clamping blocks are arranged at intervals on the inner side wall of the chuck, and a plurality of lower clamping blocks are arranged at intervals on the circumferential edge of the open end of the lower tank body, and the second driver can drive the chuck to rotate so that the upper clamping blocks and the lower clamping blocks are engaged, so that the upper tank body and the lower tank body are fixedly connected through the chuck. When the open end of the lower tank body is in contact with the open end of the upper tank body, the chuck is driven to rotate by the second driver so that the upper clamping blocks and the lower clamping blocks are engaged, so that the upper tank body and the lower tank body are locked and fixedly connected by the chuck. When releasing, it is only necessary for the second driver to drive the chuck to rotate in the opposite direction to disengage the upper clamping blocks from the lower clamping blocks.

[0010] In the aforementioned spherical dryer cover structure, a hinged frame is fixedly connected to the upper tank or the frame, a hinged shaft is fixedly connected to the outer peripheral wall of the chuck, the output shaft of the second actuator is hingedly connected to the hinged shaft, and the rear end of the second actuator is hingedly connected to the hinged frame. Both ends of the second actuator are hinged to prevent the second actuator from getting stuck, allowing the second actuator to drive the chuck to rotate and engage the upper pull block and the lower locking block.

[0011] In the aforementioned spherical dryer cover structure, a retaining ring protrudes outward from the circumferential edge of the upper tank's opening, and a retaining ring protrudes inward from the top of the chuck. The retaining ring abuts against the retaining ring, allowing the chuck to rotatably fit over the upper tank's opening. This structure, through the retaining ring and retaining ring, ensures that the chuck remains attached to the upper tank without falling off.

[0012] In the above-mentioned switch cover structure of the spherical dryer, a plurality of rotatable guide wheels are provided at intervals on the clasp, and the guide wheels can fit with the outer wall of the upper tank body. The arrangement of the guide wheels enables the chuck to rotate smoothly.

[0013] In the aforementioned spherical dryer cover structure, the spacing between two adjacent upper clamping blocks is greater than or equal to the length of the lower clamping block, and the spacing between two adjacent lower clamping blocks is greater than or equal to the length of the upper clamping block. This structure allows the upper and lower clamping blocks to pass through each other when opening and closing the upper and lower tanks, eliminating the problem of getting stuck and ensuring smooth opening and closing of the upper and lower tanks.

[0014] In the aforementioned spherical dryer cover structure, an upper slider is positioned above the upper clamping block, the top surface of which is inclined along the circumference of the chuck. A lower slider is positioned below the lower clamping block, the bottom surface of which is inclined along the circumference of the lower tank body. When the second driver drives the chuck to rotate, the top surface of the upper slider moves along the bottom surface of the lower slider, causing the upper tank body to be fixedly connected to the lower tank body via the chuck. This structure allows the upper and lower tank bodies to be locked more tightly when the lids are closed, thanks to the inclined top surface of the upper slider and the inclined bottom surface of the lower slider.

[0015] In the aforementioned spherical dryer switch cover structure, the frame includes a fixing plate with a fixing hole. A portion of the upper tank body extends through the fixing hole and is positioned above the fixing plate. The upper tank body rests against the wall of the fixing hole and is welded to the fixing plate. This structure allows for a better integration of the upper tank body and the frame, rationalizing the layout of the spherical dryer and improving its stability.

[0016] In the above-mentioned switch cover structure of the spherical dryer, the spherical dryer also includes a third driver and a stirring assembly. The third driver is fixedly connected to the upper tank body, and the stirring assembly is located in the upper tank body and the lower tank body. The open end of the upper tank body is downward and inclined inwardly downward. The third driver and the stirring assembly are both inclined. The third driver can drive the stirring assembly to rotate. A support assembly is provided on the frame. The top of the support assembly is connected to the top of the first driver, and the bottom is connected to the fixed plate.

[0017] In the above-mentioned switch cover structure of the spherical dryer, the spherical dryer also includes a fourth driver and a crushing assembly. The fourth driver is fixedly connected to the upper tank body. The crushing assembly is located in the upper tank body and the lower tank body or the crushing assembly is located in the upper tank body. The fourth driver and the crushing assembly are both arranged in a vertical direction. The fourth driver can drive the crushing assembly to rotate. The crushing knife of the crushing assembly is located in the stirring blade of the stirring assembly.

[0018] Compared with the prior art, the switch cover structure of the spherical dryer provided by the utility model has the following advantages:

[0019] 1. The upper tank and lower tank of the spherical dryer are two independent parts. When assembling, repairing or cleaning the parts inside the tank, the upper tank and the lower tank can be opened, making the spherical dryer easy to assemble and clean. During production and processing, the upper tank and the lower tank can be closed.

[0020] 2. The upper tank body of the spherical dryer is hinged to the lower tank body through the upper hinge seat, the lower hinge seat and the rotating shaft.
