Detailed Description

The present invention will be described in detail with reference to the drawings and specific embodiments, wherein prior to describing embodiments of the present invention in detail, the terms and terminology used herein are used to explain the same or similar structures and components with the same names or same reference numbers for illustrative purposes only.

Example (b):

referring to fig. 1 and 2, an apparatus for screening and threshing agricultural products includes a screen 10, and further includes a rolling roller 20 capable of displacing along a length direction of a top of the screen for rolling crops in the screen to separate fruits of the crops from plants;

referring to fig. 4, a link mechanism 30, the link mechanism includes two fixed ends 31, a rotating rod 32 connected to one fixed end, a swinging rod 33 connected to the other fixed end, and a transition rod 34 hinged between the rotating rod and the swinging rod, wherein the transition rod is further hinged to the side wall of the screen through a connecting rod 35, when in use, a driving motor for driving the rotating rod to rotate can be arranged at one fixed end, the agricultural product to be threshed is placed on the screen, the fruit is separated from the plant by the reciprocating movement of the rolling roller along the top of the screen, meanwhile, when the rotating rod rotates along the fixed end, the swinging rod is driven to swing through the transition rod, as the transition rod is connected with the screen through the connecting rod, the screen can be driven to sieve reciprocally, the fruit separated from the plant is screened below the screen, and the separation of the fruit and the plant is realized.

Further, in order to improve the rolling effect of rolling roller 20, the outer wall of the rolling roller can be provided with a hard protrusion, and the rolling effect of the plant is achieved by the hard protrusion, so that the fruit and plant separation effect is achieved.

Referring to fig. 3, as a preferred technical solution of the present invention, the top of the screen mesh 10 is provided with guide grooves 11 distributed in parallel at two opposite long sides, and two opposite roller shafts of the rolling roller are respectively provided with a roller capable of moving along the guide grooves.

In a preferred embodiment of the present invention, the fixing end 31 is a base, which is disposed on a base surface for installing the above-mentioned device for screening and threshing agricultural products, specifically, the base surface may be disposed on the ground or on a mechanical device for collecting the fruits of agricultural products.

Furthermore, after the screen screens fruits and plants, in order to improve the efficiency of separating the fruits from the plants, the base surface is arranged in a form of an inclined plane, so that the fruits separated from the plants move along the screen under the action of gravity and fall from the pores of the screen, and the screening effect is realized.

As the preferred technical scheme of the utility model, the two fixed ends 31 are arranged on the foundation surface along the same horizontal plane, namely the two fixed ends are distributed along the same horizontal plane and arranged at the same height, and the arrangement form is different from the arrangement form of the two fixed ends arranged on the foundation surface in a layered manner, so that the utility model has the characteristic of convenient installation.
