[0002] Granular or strip-shaped feeds on the market are mainly processed with the assistance of a ring die. The ring die is a very important component in feed processing and is also a consumable with a large demand. The ring die has a certain weight, so it is very laborious to install the ring die. Lifting the ring die manually is time-consuming and laborious, with a large labor intensity and low efficiency. Therefore, it is often necessary to use a machine to assist in transportation and installation.

[0003] During the production process of granular feed, the working surface of the ring die is subject to extrusion wear, so it needs to be replaced frequently. At present, there are mainly two types of ring die loaders and unloaders on the market. One is an adjustable double fork arm type ring die loader and unloader, and the other is an adjustable double fork arm ring die loader. The non-adjustable double fork arm ring die loader can only be used for ring dies of fixed sizes and is not universal for ring dies with large size differences. Although the adjustable double fork arm ring die elevator can meet the loading and unloading requirements of ring dies of different sizes, it also has problems such as complex structure, troublesome operation, and high cost. In order to solve the above problems, it is urgent to design a ring die loader and unloader with a simple structure and compatible with the loading and unloading of large and small ring dies.

[0026] Embodiment

[0027] As Figures 1 to 2 shown, a single-fork arm ring die loader-unloader includes an installation chassis 100. The installation chassis 100 is provided with a lifting installation frame 200, a lifting mechanism 300, traveling wheels 110, steering wheels 120, a hydraulic operation handle 130, etc. The hydraulic operation handle 130 is mechanically connected to the lifting mechanism 300. The lifting operation of the lifting mechanism 300 is controlled by the hydraulic operation handle 130, and at the same time, the movement of the loader-unloader can also be controlled by the hydraulic operation handle 130. Among them, the lifting installation frame 200 is fixedly installed on the installation chassis 100 through a reinforcing rib 210. One end of the reinforcing rib 210 is connected to the body of the lifting installation frame 200, and the other end is connected to the installation chassis 100. A triangular stable structure is formed among the lifting installation frame 200, the installation chassis 100, and the reinforcing rib 210. The traveling wheels 110 are installed at the front end of the installation chassis 100, and the traveling wheels 110 cannot change the direction. The steering wheels 120 are provided at the rear end of the installation chassis 100, and the steering wheels 120 can be adjusted in the reverse direction. Through the combined use of the traveling wheels 110 and the steering wheels 120, the position movement of the loader-unloader is facilitated. The lifting mechanism 300 is installed on the installation chassis 100, and a ring die fork arm 400 is installed on the driving end of the lifting mechanism 300. The ring die fork arm 400 is of a single-fork type. When loading and unloading the ring die, only the ring die fork arm 400 needs to be inserted into the middle hole of the ring die, and the ring die is supported by the ring die fork arm 400, and the lifting and lowering movement is driven by the lifting mechanism 300 to complete the adjustment of the position of the ring die. The hydraulic operation handle 130 is rotatably installed on the installation chassis 100, and the hydraulic operation handle 130 is pulled to realize the position drive of the loader-unloader.

[0028] Preferably, in order to cooperate with the movement of the loader-unloader, a handrail 220 is further provided on the lifting installation frame 200, and the setting of the handrail 220 can also control the movement direction of the loader-unloader.

[0029] Preferably, guiding sliding grooves 230 are provided on opposite inner sides of the lifting mounting frame 200. The lifting mechanism 300 includes a hydraulic cylinder 310, a linkage chain 320, a mounting plate 330, and a sliding mounting seat 340. The hydraulic cylinder 310 is installed at the middle position of the mounting base frame 100. The output end of the hydraulic cylinder 310 is perpendicular to the ground. A telescopic rod is provided on the output end of the hydraulic cylinder 310. The telescopic rod is slidably disposed in the hydraulic cylinder 310. A jacking cross bar is provided at the top end of the telescopic rod. The jacking cross bar is perpendicular to the telescopic rod. Auxiliary rollers are provided at opposite ends of the jacking cross bar. The auxiliary rollers are rotatably installed at the ends of the jacking cross bar. Pulleys are provided on opposite sides of the sliding mounting seat 340. The pulleys are slidably disposed in the guiding sliding grooves 230. One end of the linkage chain 320 is connected to a mounting cross beam installed on the lifting mounting frame 200, and the other end bypasses the auxiliary rollers and is connected to the sliding mounting seat 340. Driven by the hydraulic cylinder 310, the sliding mounting seat 340 moves up and down along the lifting mounting frame 200 (i.e., drives the pulleys to slide in the guiding sliding grooves 230). The mounting plate 330 is provided on the front end face of the sliding mounting seat 340. A fork arm fixing plate 350 is provided on the mounting plate 330. The fork arm fixing plate 350 is perpendicular to the mounting plate 340. The ring die fork arm 400 is installed on the fork arm fixing plate 350 by welding. It is worth mentioning that the ring die fork arm 400 is inclined upward, and the included angle between the ring die fork arm 400 and the fork arm fixing plate 350 is less than 90°, aiming to prevent the ring die from slipping off the ring die fork arm 400 during the process of carrying the ring die. During loading and unloading, first place the ring die on the ring die fork arm 400, and then realize the docking with the ring die by rotating the large plate end of the pellet mill.

[0030] During the production process of feed by conventional production enterprises, assuming that two different specifications of ring dies, namely the ring die of CPM3020 - 10 and the ring die of Zhengchang 320, are required, at least two fixed - type ring die loaders are needed, one adjustable double - fork - arm ring die loader is needed, while only one such single - fork ring die loader is required, and the cost of this single - fork - arm ring die loader is basically equivalent to that of a fixed double - fork - arm ring die loader, and it is only 2 / 3 of the cost of one adjustable double - fork - arm ring die loader. Therefore, this design can greatly save the production cost of the feed mill and reduce the economic expenditure on equipment configuration. At the same time, the operation method of the single - fork - arm ring die loader only requires inserting the fork arm into the through - hole in the middle of the ring die to carry and lift the ring die. Compared with the operation of the adjustable double - fork - arm loader, which also needs to be adjusted accordingly according to its outer diameter size when lifting the ring die, the single - fork - arm loader of this design is more convenient and fast to operate.

[0031] In summary, the present utility model provides a single fork arm ring die loader / unloader. This loader / unloader changes the traditional double fork arm type to a single fork arm type, and changes the original outer ring type for lifting the ring die to a bearing inner ring type. This method solves the problem that the fixed double fork arm ring die loader / unloader on the market cannot be used for ring dies of different specifications and sizes. At the same time, it also solves the problems of complex structure and high purchase cost of the adjustable double fork arm ring die loader / unloader on the market. The fork arm of the ring die of the present utility model is inclined and installed on the loader / unloader, and forms an angle less than 90° with the fork arm fixing plate, aiming to prevent the ring die from slipping off the fork arm during the process of bearing the ring die.
