Technical Field

[0001] The invention relates to the technical field of grading and screening equipment, in particular to dust-free ore crushing and grading and screening equipment. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are often expressed in percentages. Ore grade is often used to measure the value of ore, but the composition of gangue (useless minerals in the ore or minerals with very little useful components and cannot be utilized) and the amount of harmful impurities in the ore of the same effective ingredient also affect the value of the ore.

[0003] However, when crushing the ore, it is usually necessary to use a crushing roller to crush the ore. After the ore is crushed, it is easy to produce stones of different sizes. When the ore is used, if a specific size of ore is needed, the ore needs to be screened additionally, which reduces the efficiency of ore crushing. At the same time, if the ore after crushing is too large, the user needs to put the ore back into the crushing device for secondary crushing, which increases the amount of operation and easily generates a lot of dust during crushing.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1 - Figure 8 In the embodiment of the present invention, a dust-free ore crushing, grading and screening device comprises a screening box 1 and a collecting seat 2, wherein the collecting seat 2 is located below the screening box 1, and the inner wall of the screening box 1 is fixedly connected with a crushing box 3, and the outer wall at one end of the screening box 1 is provided with a feed port 4 connected with the crushing box 3, and the top of the feed port 4 is rotatably connected with a baffle 10, and the inner cavity of the crushing box 3 is provided with two crushing rollers 7, and the outer wall of the screening box 1 away from the feed port 4 is provided with a motor 5, and the crushing roller 7 is fixedly connected with a spur gear 6, and the output end of the motor 5 is connected with the spur gear 6, and the screening box 1 screens the crushed ore through a screening mechanism 8, and the screening mechanism 8 comprises a circular plate 801, and the outer wall of the screening box 1 is provided with a circular hole, and the circular plate 801 is arranged in the circular hole of the screening box 1 and fixedly connected to the outer wall of the crushing box 3, and the outer wall of the circular plate 801 is rotatably connected with a toothed disc 802, A gear ring 803 is rotatably connected between the circular hole of the screening box 1 and the circular plate 801, and a push plate 804 located in the inner cavity of the screening box 1 is fixedly connected to the outer wall of the gear ring 803, and a movable plate 805 is rotatably connected to the top of the push plate 804; the collecting seat 2 collects ores of different sizes through the collecting mechanism 9, and the screening mechanism 8 also includes a first leakage hole 806, a second leakage hole 807 and a third leakage hole 808, which are successively opened at the bottom end of the screening box 1, and an arc plate 809 is fixedly connected to one end of the circular plate 801 facing the push plate 804, and a slider 810 extending to the outer wall of the push plate 804 is slidably connected inside the push plate 804, and one end of the slider 810 is fixedly connected to a threaded rod 811 running through the movable plate 805, and a mounting frame is installed on the outer wall of the screening box 1, and the motor 5 is installed on the outer wall of the mounting frame.

[0027] In this embodiment: when the ore is crushed, the ore is put into the crushing box 3 through the feed port 4, and then the feed port 4 is blocked by the baffle 10. When the ore enters the crushing box 3, the motor 5 drives the two spur gears 6 to rotate in the opposite direction, and the rotation of the spur gears 6 drives the two crushing rollers 7 to rotate in the opposite direction to crush the ore, and the crushed ore falls into the screening box 1;

[0028] At the same time, the spur gear 6 rotates and drives the toothed disc 802 to rotate, and the rotation of the toothed disc 802 drives the gear ring 803 to rotate, and the rotation of the gear ring 803 drives the push plate 804 to perform a circumferential displacement. At this time, the slider 810 contacts the arc plate 809, and the push plate 804 and the movable plate 805 are L-shaped. The circumferential displacement of the push plate 804 drives the ore in the screening box 1 to move, and the ore displacement passes through the first leakage hole 806, the second leakage hole 807 and the third leakage hole 808 in sequence. The ore falls from the first leakage hole 806, the second leakage hole 807 and the third leakage hole 808 from small to large; if the ore is too large to fall, then as the push plate 804 continues to move, when the inclination direction of the push plate 804 changes, the ore moves along the push plate 804 until it contacts the movable plate 805. Until the slider 810 is separated from the arc plate 809, so that the slider 810 has some space to move, the movable plate 805 rotates under the action of the gravity of the ore, until the slider 810 contacts the circular plate 801, and the ore falls along the movable plate 805 and enters the crushing box 3 for crushing again. When the slider 810 contacts the arc plate 809 again, the slider 810 slides inside the force box push plate 804, and the displacement of the slider 810 drives the threaded rod 811 to move, and the displacement of the threaded rod 811 drives the movable plate 805 to rotate until it is reset, so as to automatically screen the crushed ore and automatically put the larger ore back into the crushing box 3 for crushing, thereby reducing labor costs, and the dust generated during crushing is located in the screening box 1, thereby preventing the dust from escaping.
