Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following embodiments. It should be emphasized that the following description is merely exemplary in nature and is not intended to limit the scope of the invention or its application.

Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts, unless otherwise specified.

1-3, the screen cylinder comprises a main body frame 2, and screens (22,23) arranged on the side surfaces of the main body frame 2, wherein the screens (22,23) are divided into a large screen 23 and a small screen 22. The middle parts of the screens (22 and 23) are also fixed with a connecting plate 5, and the large screen 23 and the small screen 22 are respectively fixed on the main body frames 2 at the two sides of the connecting plate 5. In order to reinforce the overall strength of the main body frame 2, a plurality of reinforcing rods 21 are additionally arranged on the main body frame 2. Set up a plurality of plectrum 6 on stiffener 21, and all plectrums 6 are arranged in order and are the spiral and distribute, and a sieve section of thick bamboo stirs calcium carbonate building stones through plectrum 6 at the pivoted in-process, is favorable to improving the efficiency that a sieve section of thick bamboo shifted its inside calcium carbonate building stones.

However, the calcium carbonate stones roll along with the sieve cylinder and then are scattered out of the sieve cylinder from the sieve screens (22,23), so that the calcium carbonate stones are scattered in a large range and are not easy to collect; meanwhile, the calcium carbonate stones are thrown off by the screen cylinder and then fall to the bottom of the screen meshes (22,23), so that the impact force borne by the screen meshes (22,23) is greatly enhanced, and the meshes of the screen meshes (22,23) are easily damaged. Therefore, the arc-shaped retaining cover 3 which is coaxial with the screen cylinder and has the same length is arranged in the screen cylinder, a support rod 32 is fixedly welded at the center of the top of the arc-shaped retaining cover 3, and two ends of the support rod 32 extend out of two sides of the arc-shaped retaining cover 3. During the use, the both ends of bracing piece 32 are passed through the bearing and are rotated and connect on fixed wall 7, and fixed wall 7 can be wall or other firm fixings to hang arc fender cover 3 in the inside of a sieve section of thick bamboo, make arc fender cover 3 have the interval at circumferencial direction's tip and a sieve section of thick bamboo inner wall, a sieve section of thick bamboo passes through the bracing piece 32 swing. In a preferred embodiment, the diameter of the screen cylinder is larger than that of the arc-shaped shielding cover 3, the circle center of the arc-shaped shielding cover 3 is on one diameter of the screen cylinder, and the horizontal height of the circle center of the screen cylinder is higher than that of the circle center of the arc-shaped shielding cover 3. The design can draw the interval between the end part of the arc-shaped retaining cover 3 in the circumferential direction and the inner wall of the screen drum, and meanwhile, the arc-shaped retaining cover 3 is arranged at a lower position and can limit the area of calcium carbonate stones falling out of the screen drum from the screens (22,23), so that the collection efficiency is improved; moreover, the design of the arc-shaped shielding cover 3 can also be used as a dust shielding barrier, and the dust emission is reduced by more than 65% in the material selecting process. It should be noted that, in order to prevent the striking of the poking piece 6 to the end of the arc-shaped shield 3 in the circumferential direction, the height from the vertex of the poking piece 6 to the inner wall of the screen cylinder is designed to be smaller than the distance from the end of the arc-shaped shield 3 in the circumferential direction to the inner wall of the screen cylinder. Furthermore, in order to improve the shielding capacity of the arc-shaped shielding cover 3, the distance between the end part of the arc-shaped shielding cover 3 in the circumferential direction and the inner wall of the screen cylinder is designed to be smaller than or equal to the minimum caliber of the small screen mesh. A cylindrical rod 31 is welded at the end part of the arc-shaped blocking cover 3 in the circumferential direction so as to improve the rigidity of the end part of the arc-shaped blocking cover 3 in the circumferential direction and avoid the arc-shaped blocking cover 3 from being deformed by calcium carbonate stones to influence the use.
