DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-4 , the present invention provides a technical solution: a double-toothed roll crusher with adjustable gap, including a machine body 1 and a feed inlet 2. The feed inlet 2 is arranged at the top of the machine body 1. The double-toothed roll crusher with adjustable gap further includes: a protection mechanism 3 arranged inside the feed inlet 2, and an auxiliary mechanism 4 arranged on the outer wall of the feed inlet 2. Among them, the protection mechanism 3 can prevent the ore from bouncing during crushing, and the auxiliary mechanism 4 can reset the protection mechanism 3.

[0019] Specifically, the protection mechanism 3 includes: a baffle 301, a top rod 302, a pull rope 303, a sleeve 304, and a sheave 305;

[0020] The baffle 301 is rotatably arranged on both sides of the inner wall of the feed inlet 2. The baffle 301 can protect the ore during crushing. The top rod 302 is attached to the top of the baffle 301, and the outer wall of the top rod 302 is connected to the inner wall of the feed inlet 2. The pull ropes 303 are fixedly arranged on both sides of the top of the baffle 301. The pull ropes 303 can reset the baffle 301. The sleeve 304 is sleeved on the outer wall of the pull rope 303. The sleeve 304 can limit the pull rope 303, and the outer wall of the sleeve 304 is connected to the inner wall of the feed inlet 2. The sheaves 305 are fixedly arranged on both sides of the outer wall of the feed inlet 2. Among them, when the baffle 301 is pressed down by the ore, the baffle 301 rotates downward, and then drives the pull ropes 303 to be pulled downward simultaneously inside the sleeve 304. The material of the pull ropes 303 is a metal material, and grooves are provided on the inner wall of the feed inlet 2.

[0021] More specifically, the auxiliary mechanism 4 includes: a groove rod 401, a spring 402, and a cross plate 403;

[0022] The groove rod 401 is fixedly arranged on both sides of the outer wall of the feed inlet 2. The spring 402 is fixedly arranged at the top end inside the groove rod 401. The spring 402 is used to push the cross plate 403 downward. The cross plate 403 is attached to the bottom end of the spring 402, and the top end of the cross plate 403 is connected to the other end of the pull rope 303. Among them, when the pull rope 303 is pulled, it drives the cross plate 403 to move upward inside the groove rod 401 and compress the spring 402. A cavity is provided inside the groove rod 401.

[0023] Working principle: When the double-toothed roll crusher with adjustable gap starts to be used, the user first pours the ore to be crushed from the top of the feed inlet 2. Then, when the ore contacts the baffle 301, it presses the baffle 301 downward. Then, by rotating the baffle 301 downward, a gap is opened inside the baffle 301, and the ore falls downward into the interior of the machine body 1 for crushing work. During the downward rotation of the baffle 301, the pull rope 303 is pulled downward. Then, the pull rope 303 moves downward inside the sleeve 304 and drives the cross plate 403 to slide upward inside the groove rod 401. When the cross plate 403 slides upward inside the groove rod 401, it squeezes the spring 402. Then, when all the ore slides from the top of the baffle 301 into the interior of the machine body 1, when there is no downward pressing force on the top of the baffle 301, the cross plate 403 is pushed downward by the reaction force of the spring 402. Then, when the cross plate 403 moves downward inside the groove rod 401, it drives the pull rope 303 to be pulled downward simultaneously, and the pull rope 303 is limited by the sheave 305. Then, the baffle 301 is pulled by the pull rope 303 to reset so that the baffle 301 fits against the bottom end of the ejector rod 302. Then, during the crushing of the ore by the machine body 1, the ore that bounces up can be effectively prevented from popping out of the feed inlet 2 through the shielding of the feed inlet 2, thus causing harm to the staff.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
