The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] The present invention provides a bauxite crushing and screening integrated machine. Figure 1-4 As shown, it includes a crushing box 1: the inner side wall of the crushing box 1 is fixedly connected to a rolling seat 2, the outer wall of the rolling seat 2 is provided with a discharge hole 3, the inner top wall of the crushing box 1 is fixedly connected to a telescopic sleeve 5, one end of the telescopic sleeve 5 is fixedly connected to a connecting frame 4, the outer wall of the telescopic sleeve 5 is movably connected to a spring 6, the top of the rolling seat 2 is fixedly connected to a hydraulic cylinder 7, the bottom of the connecting frame 4 is fixedly connected to a rolling head 9, the inner side wall of the crushing box 1 is fixedly connected to a ramp 10, the back of the crushing box 1 is fixedly connected to a mounting frame 11, the front of the mounting frame 11 is fixedly connected to a motor 12, the output shaft of the motor 12 is fixedly connected to a first rolling roller 13 through a coupling, the shaft end of the first rolling roller 13 is fixedly connected to a main gear 14, the outer wall of the main gear 14 is movably connected to a sub-gear 15, the inner wall of the sub-gear 15 is fixedly connected to a second rolling roller 16, and a discharge port 17 is provided at the bottom of the crushing box 1.
[0022] It should be noted that, since most of the current bauxite crushing processes are simple, the bauxite is not fully crushed during crushing, resulting in its particles of different sizes and uneven crushing, which requires multiple crushing operations, affecting the processing quality and production progress. Therefore, in order to solve the problem that bauxite is not fully crushed during crushing, resulting in its particles of different sizes and uneven crushing, which requires multiple crushing operations, this solution sets a rolling seat 2. When bauxite is poured into the crushing box 1, the hydraulic cylinder 7 drives the connecting frame 4 to rise and move, so that the rolling head 9 and the rolling seat 2 have a certain distance, and the hydraulic cylinder 7 resets, so that the rolling head 9 falls down quickly, and contacts and collides with the rolling seat 2, so that the bauxite can be preliminarily crushed. The preliminarily crushed bauxite will fall down between the two rolling rollers through the discharge hole 3 on the rolling seat 2, and the first rolling roller 13 and the second rolling roller 16 are driven to rotate by the motor 12, so that the bauxite can be subjected to secondary rolling and refinement, so that it is rolled evenly.
[0023] Specifically, in this embodiment, this solution mainly includes a filter box 18 fixedly connected to the bottom of the crushing box 1, an electric push rod 19 fixedly connected to the top of the filter box 18, and a screen 20 fixedly connected to the output end of the electric push rod 19. A feed port 21 is provided on the front of the crushing box 1, which can drive the screen 20 to move up and down, thereby facilitating the shaking and filtering of the bauxite accumulated on the filter 20 to avoid clogging of the filter 20, and facilitating the loading of bauxite.
[0024] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the screen 20 is movably connected to the filter box 18 through an electric push rod 19, and a discharge port is provided on one side of the filter box 18, which can drive the screen 20 to move up and down, thereby facilitating the shaking filtration of the bauxite accumulated on the filter 20 to avoid clogging of the filter 20, and at the same time facilitating the discharge and collection of the filtered bauxite.
[0025] In this embodiment, the hydraulic cylinder 7 is first started to drive the connecting frame 4 to move upward, so that a certain distance is generated between the rolling head 9 and the rolling seat 2, and then the bauxite is poured into the rolling seat 2 in the crushing box 1 through the feed port 21, and then the hydraulic cylinder 7 is driven to reset so that it no longer supports the connecting frame 4, so that the connecting frame 4 and the rolling head 9 fall downward and reset in cooperation with the telescopic sleeve 5 and the spring 6, and when the rolling head 9 falls downward, it will collide with the bauxite in the rolling seat 2 and crush it. During continuous operation, the initially crushed bauxite falls downward through the discharge hole 3 on the rolling seat 2, and then the first rolling roller 13 is driven to rotate by the motor 12, so that the main gear 14 installed on the shaft end rotates and engages with the sub-gear 15, thereby driving the second rolling roller 16 to rotate in the opposite direction, so that the first rolling roller 13 and the second rolling roller 16 crush and roll the bauxite again to make it crushed evenly.
[0026] In a further preferred embodiment of the present invention, Figure 1 As shown, the rolling head 9 is movably connected to the rolling seat 2 through the telescopic sleeve 5, and the rolling head 9 is a semicircular rolling head.
[0027] In this embodiment, the rolling head 9 can be reset when it moves upward, so that the bauxite can be rolled and refined, and it can also play a role in supporting and positioning it so that it can work stably.
[0028] In a further preferred embodiment of the present invention, Figure 3 As shown, the shaft ends of the first laminating roller 13 and the shaft ends of the second laminating roller 16 are both provided with bearings, and the first laminating roller 13 and the second laminating roller 16 are both movably connected to the crushing box 1 through the bearings.
[0029] In this embodiment, the first laminating roller 13 and the second laminating roller 16 can be positioned to improve their stability during rotation and laminating.
[0030] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the rolling seat 2 is a semicircular rolling seat, and a mounting plate is provided on the outer wall of the rolling seat 2, and the rolling seat 2 is fixedly connected to the crushing box 1 and the hydraulic cylinder 7 through the mounting plate.
[0031] In this embodiment, the convenient rolling head 9 can be matched with the rolling seat 2, and can fully contact with the bauxite and fully crush it.
[0032] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the output end of the hydraulic cylinder 7 is fixedly connected to a pushing block 8, and the pushing block 8 is a thickened sponge pushing block.
[0033] In this embodiment, the hydraulic cylinder 7 can push the connecting frame 4 to move upward, and when the connecting frame 4 falls downward, it plays a role of impact, thereby reducing the impact pressure on the hydraulic cylinder 7.
