Embodiment Construction
[0006] The embodiment is described in detail in conjunction with the accompanying drawings. The present invention is an improvement to the prior art. It includes a bar screen plate and a screen box. A middle partition 2, the upper and lower sieve plate fixing seats 3 are respectively arranged on the two sides of the middle partition corresponding to the two sides of the screen box, and the width of the lower sieve plate fixing seat is 50 less than the width of the upper sieve plate fixing seat. mm, which can facilitate the installation of the lower sieve plate. A bar sieve plate 4 is respectively installed between the fixing seats on both sides of the middle partition and the corresponding fixing seats on the two sides of the screen box. T-head bolts 6 are respectively connected between them.

The invention discloses a double-channel bar screen plate which comprises a screen box and a bar screen plate, wherein a middle clapboard is fixed at the middle of the cross beam of the screen box in parallel to two side plates of the screen box; upper and lower screen plate fixing seats are respectively arranged at two sides, corresponding to the two side plates of the screen box, of the middle clapboard; the width of the lower screen plate fixing seat is smaller than that of the upper screen plate fixing seat; bar screen plates are respectively installed between the fixing seats at the both sides of the middle clapboard and the fixing seats corresponding to two side plates of the screen box; and T-shaped headed bolts are connected between each bar screen plate and the fixing seat thereof. As two bar screen surface channels are installed in one screen box, the width and weight of each bar screen plate are greatly reduced, the cracking phenomenon of the locating slot and side plates is avoided, the double-channel bar screen plate is convenient to install, the service life is prolonged, and the double-channel bar screen plate is particularly suitable for installation and use of large vibration screens.
Description
Technical field: [0001] The invention relates to screening equipment, in particular to a double-channel rod sieve plate suitable for a large vibrating screen with a sieve plate width greater than 2 meters. Background technique: [0002] Existing rod sieve plates with a width of more than 2 meters are used to screen materials in a single channel, and cracking of positioning grooves and side plates is prone to occur during use, which not only affects screening efficiency and increases maintenance costs, but also Short life. Invention content: [0003] The object of the present invention is to provide a double-channel rod sieve plate with high screening efficiency, long service life and few failures. [0004] The technical solution of the present invention is accomplished in the following manner, which includes a screen box and a bar screen plate, and is characterized in that: a middle partition plate is fixed parallel to the two side plates of the screen box in the middle o...
