Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

As shown in figures 1-2, the utility model provides a novel crop screening device, which comprises a box body 1, the box body comprises an inner box body 1-1 and an outer box body 1-2, the outer box body 1-2 is arranged outside the inner box body 1-1, a cavity 1-3 is arranged between the outer box body 1-2 and the inner box body 1-1, a plurality of guide screen meshes 2 are arranged in the inner box body 1-1 from top to bottom, each guide screen mesh 2 is fixedly connected with the inner side wall of the inner box body 1-1, openings for conveying common body impurities collected on each guide screen mesh 2 into the cavity are arranged on the side wall of the inner box body 1-1, the lower ends of each guide screen mesh 2 are in one-to-one correspondence and communication with each opening, an impurity outlet 3 communicated with the cavity 1-3 is arranged at the bottom of the outer box body 1-2, the bottom of the outer box body 1-2 is also provided with a crop outlet 6 communicated with the inner box body 1-1, the outer bottom wall of the outer box body 1 is provided with a vibration motor 4, and the vibration motor 4 is electrically connected with a power supply through a first control switch.

In the embodiment, soil blocks, straws and other solid impurities exist in crops in the harvesting process, so that the crops need to be screened when being reprocessed, but the impurities of the existing crop screening device are not thoroughly removed and need to be removed for a plurality of times, so that the problem that the impurity removal efficiency is seriously influenced because the impurities are not thoroughly removed and need to be removed for a plurality of times in the existing mechanical impurity removal equipment is solved, the harvested crops are conveyed into the box body 1 through the conveying pipe, the control switch connected with the vibrating motor 4 is turned on, the vibrating motor 4 rotates (the model of the vibrating motor is YZU-1-2) to drive the box body 1 to vibrate, the guide screen 2 arranged in the inner box body 1-1 is driven to vibrate, and the crops vibrate on the guide screen 2, because the aperture of guide screen 2 is greater than the particle size of crops, the aperture of guide screen 2 is less than the size of impurity, so when the impurity size in the crops is unanimous basically, at this moment the interior crops granule of box 1-1 in by guide screen 2 carry out once screening can, just can realize the edulcoration to crops, but when the impurity size in the crops is different, so guide screen 2 in the box 1 need set different apertures into, the impurity of leaving over on the screen cloth has the opening to flow into in the cavity, the vibration through vibrating motor 4 makes impurity collect by impurity export 3, make the crops after the edulcoration obtain collecting in 6 departments of crops export through the vibration of vibrating motor 4.

In order to avoid that impurities on the upper guide screen 2 in the inner box body 1-1 fall onto the lower guide screen 2 and influence the screening efficiency of the guide screen 2, baffles are arranged on the front side wall and the rear side wall of the guide screen 2 and are abutted against the front side wall and the rear side wall of the inner box body 1-1.

In order to realize screening once just can the edulcoration thoroughly, need not edulcoration many times, a plurality of guide screen 2's aperture reduces from top to bottom in proper order.

The harvested crops are conveyed into the inner box body 1-1 by the feed hopper, so the top of the outer box body 1-2 is provided with the feed hopper 7 communicated with the inner box body 1-1.

In order to prevent the screened crops from blocking the inner box body 1-1 and affecting the screening efficiency, the motor 5-1 (model number: YE2-132M) is started to rotate, the motor 5-1 drives the rotating shaft 5-2 to rotate, the rotating shaft 5-2 drives the spiral rotating conveying blade 5-3 to rotate, the crops are rapidly output from the crop outlet 6 under the pushing of the conveying blade 5-3, the accumulation probability of the crops in the inner box body 1-1 is reduced, the crop conveying device 5 is further included, the crop conveying device 5 is positioned below the lowest layer guide screen 2, the crop conveying device 5 comprises the motor 5-1, the rotating shaft 5-2 and the spiral conveying blade 5-3, the rotating shaft 5-2 is horizontally arranged in the inner box body 1-1, one end of the rotating shaft 5-2 is connected with the inner box body 1-1 through a bearing, the other end of the rotating shaft 5-2 is connected with an output shaft of a motor 5-1 arranged on the outer wall of the outer box body 1-2, the conveying blade 5-3 is arranged on the rotating shaft, and the motor 5-1 is electrically connected with a power supply through a second control switch.

In order to reduce the possibility that dust generated in the screening process can be raised and influence the health of workers, the dust suction amount of a human body can be effectively reduced by arranging a gas collecting hood, a suction pump 10 (the model of the suction pump is SF31-SPV700EH) and a gas filtering device (the model of the gas filtering device is GL41-H), so that a gas collecting hood 8 is arranged above the feed hopper 7, the gas collecting hood 8 is communicated with a gas inlet of the suction pump 10 arranged outside the outer box 1-2 through a gas conveying pipe 9, a gas outlet of the suction pump 10 is communicated with the gas filtering device, and the suction pump 10 is electrically connected with a power supply through a third control switch.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
