Background

In the production process of fodder, in order to improve the quality and the efficiency of follow-up production, reduce the wearing and tearing to mechanical equipment, all can carry out the primary screen to the raw materials usually, and the main objective is to get rid of impurity such as straw, mud piece, maize leaf, corn cob core and even metal clast that exist in the raw materials. The primary cleaning sieve is mainly used for separating raw materials entering the inside of a sieve cylinder through sieve pores on the surface of the sieve cylinder by a circular sieve cylinder rotating at a low speed. Qualified raw materials fall to a discharge hole through a sieve mesh; the large impurities are conveyed to a large impurity outlet by a spiral material guide plate in the screen cylinder. Because the circular screen drum is made of sheet metal parts, the roundness cannot be guaranteed, after raw materials are added into the screen drum, the screen drum is subjected to larger additional moment in the rotating process, so that the connecting bolt of the screen drum and the transmission shaft is easy to fatigue fracture, and meanwhile, when the screen drum rotates, larger vibration can be generated due to uneven stress, and the service life of the bolt is also damaged; the traditional primary cleaning sieve can not control the feeding speed, so that partial raw materials are not completely screened out and are conveyed to a large impurity outlet by a spiral material guide plate, and the raw materials are wasted.

To this end, we propose a scalping screen for feed production to solve at least partially the above problems.

Detailed Description

The technical solutions in the implementation of the present invention will be clear from the following description and accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 5, the precleaner for feed production provided by the embodiment of the present invention comprises a frame 1 and a screen drum 9 horizontally installed in the frame 1, wherein a storage hopper 4 is arranged at the left end of the screen drum 9, a feed hopper 3 is arranged at the top of the storage hopper 4, and a screw conveyor 5 with an output end inserted into the screen drum 9 is arranged at the bottom of the storage hopper 4; a barrel frame 10 matched with the screen barrel 9 is arranged outside the screen barrel 9, guide rail rings 13 are fixedly sleeved at two ends of the barrel frame 10, and a plurality of guide wheels 14 for supporting and damping are arranged on the guide rail rings 13; the right end of the barrel frame 10 is connected with a motor 12 through a coupling 11. Traditional scalping machine, a sieve section of thick bamboo 9 is direct to be connected through transmission shaft and motor, when leading to motor drive sieve section of thick bamboo 9 to rotate, because the inside weight distribution inequality of a sieve section of thick bamboo 9 leads to a sieve section of thick bamboo 9 to rotate and produces the vibration, and the vibration direct transmission gives transmission shaft and motor, leads to connecting bolt and motor to damage easily. As shown in figure 2, in the improved precleaner, a barrel frame 10 is arranged outside a screen barrel 9, the barrel frame 10 is connected with a motor 12 through a coupler 11, a guide rail ring 13 and a guide wheel 14 which are arranged on the barrel frame 10 can be made of plastic materials and used for reducing noise generated during rotation, a damping structure is arranged on the guide wheel 14, and damage to each connecting bolt in a rack 1 caused by vibration generated when the screen barrel 9 rotates is further reduced.

Further, the wheel shaft 15 of the guide wheel 14 is rotatably fixed on the support rod 16, a rod sleeve 19 is slidably sleeved at one end of the support rod 16 far away from the guide wheel 14, a spring 17 is arranged between the support rod 16 and the rod sleeve 19, a boss 18 for preventing the support rod 16 and the rod sleeve 19 from being separated is arranged on the support rod 16, and the rod sleeve 19 is fixed on the rack 1. The damage of vibration generated when the screen drum 9 rotates to each bolt on the frame 1 is reduced by arranging the spring 17.

Further, the coupling 11 is a telescopic universal coupling. By adopting the telescopic universal coupling, the influence of the slight vibration of the screen drum 9 on the motor 12 can be eliminated well, the motor 12 can be protected well, and meanwhile, the rotation of the transmission shaft of the motor 12 can be stably transmitted to the screen drum 9.

Further, the screw conveyor 5 is driven by a low-speed motor 6. Since the screening speed of the screen drum 9 to the raw material is not very fast, the slow feeding of the screw conveyer 5 driven by the low-speed motor 6 is more appropriate to the work of the screen drum 9.

Further, a second discharging hopper 8 is arranged under the screen drum 9, and a first discharging hopper 7 is arranged under the left end opening of the screen drum 9. The second storage hopper 8 is used for receiving the screened raw material and the first storage hopper 7 is used for receiving the screened impurities, so that the separated treatment is convenient.

Furthermore, an observation window 2 is arranged on the frame 1. The working condition of the primary cleaning screen is convenient to observe.

When in use: the proper screen drum 9 is selected according to the size of the raw material particles to be screened, the screen drum 9 is arranged in a drum frame 10, the raw material is poured into the feed hopper 3, the raw material can be temporarily stored in the storage hopper 4, and the screw conveyer 5 starts to convey the raw material in the storage hopper 4 into the screen drum 9 under the driving of the low-speed motor 6. The motor 12 is started, the motor 12 drives the barrel frame 10 to rotate through the telescopic universal coupling, the guide rail ring 13 begins to roll on the guide wheel 14, and the spring 17 plays a role in damping, so that fatigue damage of bolts of all parts in the frame 1 caused by eccentric rotation of the screen barrel 9 is reduced, and noise generated by vibration is reduced.
