Description

Technical Field

[0001] The utility model relates to the technical field of corn material recovery equipment, in particular to a seed recovery device and a corn harvester with the device. Background Art

[0002] A corn harvester is an agricultural machine that uses machinery to complete multiple operations of corn at one time, such as picking ears, husking, stacking, and returning the stems to the field when the corn is ripe. Corn harvesters are generally divided into three-row corn harvesters and two-row corn harvesters according to different production needs. Among them, the three rows and two rows of corn harvesters generally refer to the number of harvesting and husking equipment. Two rows means that the harvester has two sets of corn harvesting and husking equipment working together, and three rows means that the harvester has three sets of corn harvesting and husking equipment working together. When the corn harvester is husking, the corn kernels on the corn ears sometimes fall off. In the past, when harvesting corn, these fallen kernels were generally directly scattered on the ground, resulting in a waste of corn kernels. In order to solve this problem, some corn harvesters are designed to be used for harvesting corn. A full-length recovery trough is provided below the peeling roller on the rice harvester, and a fan is also provided on the frame of the corn harvester. The fan extends through the air duct to the top of the recovery trough for blowing, so as to blow away impurities such as debris and broken straw that fall with the grains. Generally, the blowing work is carried out by only one fan, and two or three air ducts are provided according to the specifications of the corn harvester. In order to meet the blowing power, the fan is generally large in size. The large fan is installed on the frame of the corn harvester, and a set of special power drive devices is also required to be installed, which increases the space occupancy rate of the fan, and the recovery trough will also occupy a large space on the frame of the corn harvester, which will affect the assembly of other equipment. Therefore, the current grain recovery device still has great disadvantages. Utility Model Content

The impurity discharge slope 11 is set on the right side of the recovery trough 3. The impurity discharge fan 10 is started to blow air toward the side of the discharge port 4a. The impurities such as broken leaves and dust blown away will fall onto the impurity discharge slope 11 and then slide down on the impurity discharge slope 11.

[0026] like Figure 4-5 As shown, in the first embodiment, two groups of material receiving mechanisms 12 are symmetrically arranged, and the two groups of material receiving mechanisms 12 are respectively arranged below the two groups of peeling rollers.

[0027] The material receiving mechanism 12 includes a first material receiving trough 13, which is horizontally arranged below each peeling roller. The first material receiving trough 13 is evenly provided with leakage holes 13a on its left and right side walls and bottom wall. Corn kernels leak out of the leakage holes 13a and finally fall into the receiving trough 5.

The receiving trough 5 is symmetrically provided with two inclined first material receiving plates 21 on the rear side of its upper end opening. The first material receiving plates 21 correspond to the positions of each peeling roller.

[0028] In the first embodiment, the driving end of the screw conveyor is connected to the transmission shaft of the corn harvester frame through a flexible shaft, thereby driving the screw conveyor to rotate; one of the first transmission rollers 14 and one end of the shaftless screw conveyor 9 located in the discharge box 4 are connected to the transmission shaft on the corn harvester through a driving gear and a chain. Taking the first transmission roller 14 as an example, a driving gear is provided at the end of one of the first transmission rollers 14, and a driving gear is also provided on the transmission shaft corresponding to the position of the driving gear on the corn harvester. The two driving gears are connected in series through a chain, thereby realizing the rotation of the first conveyor belt 15.

[0029] like Figure 6 As shown, in the second embodiment, three groups of material receiving mechanisms 12 are evenly arranged, and the three groups of material receiving mechanisms 12 are arranged below the three groups of peeling rollers.

[0030] The material receiving mechanism 12 includes a second U-shaped material receiving trough 17 arranged below each peeling roller.
