Description

Technical Field

[0001] This utility model relates to the field of corn harvester technology, and in particular to a novel grain recovery device for a front-mounted self-propelled corn harvester with a peeling function. Background Technology

[0002] A corn harvester is an agricultural implement that mechanically completes multiple operations on corn in one pass when it is ripe, including ear picking, husking, stacking, and returning the stalks to the field. Depending on production needs, corn harvesters are generally divided into three-row and two-row models. The "three-row" and "two-row" designations usually refer to the number of harvesting and husking devices. Two-row means the harvester has two sets of harvesting and husking devices working together, while three-row means it has three sets. During the husking process, corn kernels sometimes fall off the ears. Traditionally, these fallen kernels were simply scattered onto the ground during harvesting. This results in the waste of corn kernels. Patent No. CN202421252753.7, entitled "A kernel recycling device and a corn harvester with the device", discloses a kernel recycling device. It has a set of impurity removal fans installed on the frame. The impurity removal fans blow air towards the lower feed box to blow away impurities such as broken leaves and dust from the kernels. Since this impurity removal method is carried out by blowing during the kernels' fall, the kernels fall at a relatively fast speed, and some impurities can easily fall into the recycling trough along with the kernels. This cannot fully remove the impurities from the kernels, and a secondary cleaning of the impurities in the recycling trough is required afterward, which brings great inconvenience to the kernel recycling work. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of grain recovery device for a front-mounted self-propelled corn harvester, thereby effectively solving the shortcomings of the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel kernel recovery device for a front-mounted self-propelled corn harvester, comprising a corn harvester frame, on which a peeling roller is mounted, and several material receiving mechanisms are mounted on the frame below the peeling roller. A recovery feeder is mounted on the frame at the lower end of each material receiving mechanism, and a flexible hose feeder is mounted at the feeding end of the recovery feeder. A [missing information - likely a device or component] is mounted on the frame at the feeding end of the flexible hose feeder. The vehicle has a recycling trough with an opening at the top. The raw material is transported into the recycling trough through the flexible hose feeder. A fan is also installed on the frame. Several air outlets are arranged side by side on the casing of the fan. Air ducts are connected to the air outlets. An air outlet head is installed on the frame at the position between the feeding end of the flexible hose feeder and the recycling trough. The air duct is connected to the recycling feeder and the air outlet head respectively. The air outlet of the air outlet head blows air towards the side of the falling raw material through the air duct. The air duct also blows air into the recycling feeder.

[0005] Furthermore, the recycling feeder includes a U-shaped receiving bin, with a first feeding auger at the bottom of the receiving bin. A transfer cylinder is horizontally positioned at the feeding end of the receiving bin, with both ends of the transfer cylinder extending outward from the receiving bin. The portion of the transfer cylinder inside the receiving bin has a feeding notch corresponding to the end of the first feeding auger. A flexible hose feeder is connected to one end of the transfer cylinder, and the other end of the flexible hose feeder extends above the recycling trough. Several air holes are provided on the side wall of the receiving bin above the first feeding auger, with the number of air holes being the same as the number of receiving mechanisms. A connector pipe is provided in the receiving bin at the position corresponding to the air holes, and the air pipe is connected to the connector pipe.

[0006] Furthermore, a hollow guide box is provided on the inner wall of the receiving bin at the position corresponding to each of the air holes, and an air outlet is provided at the lower end of the guide box on the side facing the first feeding auger.

[0007] Furthermore, the receiving bin has a long strip-shaped discharge port on the side wall opposite to the flow guide box.

[0010] Furthermore, the hose feeder includes a feeding hose connected to the transfer cylinder, a hollow discharge box is provided on the frame corresponding to the position above the recycling trough, the other end of the feeding hose is connected to the discharge box, the bottom of the discharge box is provided with a discharge port, a shaftless conveying auger is provided inside the feeding hose, one end of the shaftless conveying auger extends into the transfer cylinder, and the air outlet is located between the discharge box and the recycling trough.

[0011] Furthermore, the number of air outlets on the fan is greater than the sum of the number of receiving mechanisms and the number of air outlet heads, and each air outlet is connected to the connector pipe and the air outlet head respectively through the air pipe.

[0012] Furthermore, there are 5-6 air outlets, 2-3 material receiving mechanisms arranged side by side, and 1-2 air outlet pipe heads.

[0013] The above-mentioned technical solution of this utility model has the following beneficial effects: This utility model improves the structure of the recycling feeder and works with the blower on the frame to perform the purging operation. The blower sends air to the recycling feeder and the air outlet head through the air duct. In this way, the recycled grains can first be blown to remove impurities at the recycling feeder. Then, when the grains fall into the recycling tank, they will be purged a second time through the air outlet head, so that the impurities in the recycled grains can be fully blown away, ensuring the cleanliness of the grains in the recycling tank. This brings great convenience to the subsequent processing of the recycled grains. Attached Figure Description

[0021] like Figure 1-5 As shown in this embodiment, a novel grain recovery device for a front-mounted self-propelled corn harvester includes a corn harvester frame. A peeling roller is mounted on the frame. Several receiving mechanisms 1 are positioned below the peeling roller on the frame.

An air outlet head 8 is installed on the frame between the feeding end of the flexible hose feeder 3 and the recycling tank 4. The air duct 7 is connected to the recycling feeder 2 and the air outlet head 8 respectively. The air outlet of the air outlet head 8 blows air towards the side of the falling feed material through the air duct 7. The air duct 7 also blows air into the recycling feeder 2.

[0022] The recycling feeder 2 includes a U-shaped receiving bin 9. A first feeding auger 10 is installed at the bottom of the receiving bin 9. A transfer cylinder 11 is horizontally placed at the feeding end of the receiving bin 9. Both ends of the transfer cylinder 11 extend outward from the receiving bin 9. The portion of the transfer cylinder 11 inside the receiving bin 9 is provided with a feeding notch 11a, which corresponds to the end position of the first feeding auger 10. A flexible hose feeder 3 is connected to one end of the transfer cylinder 11, and the other end of the flexible hose feeder 3 extends above the recycling tank 4. Several air holes are provided on the side wall of the receiving bin 9 at positions corresponding to the first feeding auger 10. The number of air holes is the same as the number of receiving mechanisms 1. A connector pipe 12 is provided at the position corresponding to the air hole in the receiving bin 9. The air duct 7 is connected to the connector pipe 12.

[0023] A hollow guide box 13 is provided on the inner wall of the receiving hopper 9 at the position corresponding to each air hole. An air outlet is provided at the lower end of the guide box 13 on the side facing the first feeding auger 10.

[0024] The receiving bin 9 has a long strip-shaped discharge port 14 on the side wall opposite to the flow guide box 13.

[0025] The receiving mechanism 1 includes a semi-circular receiving trough 15, and a second feeding auger 16 is provided at the bottom of the receiving trough 15. The receiving trough 15 has a material leakage hole 15a on its bottom wall.

[0026] The receiving trough 15 is provided with a retaining edge 17 at its upper edge.

[0027] The flexible hose feeder 3 includes a flexible hose 18 connected to the transfer cylinder 11. A hollow discharge box 19 is provided on the frame above the recycling tank 4. The other end of the flexible hose 18 is connected to the discharge box 19. The bottom of the discharge box 19 is provided with a discharge port. A shaftless conveying auger 20 is provided inside the flexible hose 18. One end of the shaftless conveying auger 20 extends into the transfer cylinder 11. The air outlet head 8 is located between the discharge box 19 and the recycling tank 4.

[0028] The number of air outlets 6 on the blower 5 is greater than the sum of the number of receiving mechanisms 1 and the number of air outlet heads 8. Each air outlet 6 is connected to the connector pipe 12 and the air outlet head 8 respectively through the air pipe 7.

[0029] There are 5-6 air outlets 6, 2-3 material receiving mechanisms 2 arranged side by side, and 1-2 air outlet pipe heads 8.

[0030] If it is a two-row corn harvester, then two sets of receiving mechanisms 1 are set for the two sets of peeling rollers. Correspondingly, there are two connector pipes 12. Five air outlets 6 are selected on the blower 5. One or two air outlet heads can be set according to the blowing needs. In this way, the extra air outlets 6 are blocked with plugs when in use, so as to serve as backup air outlets 6.

[0031] If it is a three-row corn harvester, then three sets of receiving mechanisms 1 are set up for the three sets of peeling rollers, the number of connector pipes 12 is three, the air outlets 6 on the blower 5 are arranged in six, and the air outlet head 8 is set in one or two according to the needs. Correspondingly, the extra air outlets 6 are also blocked with plugs to serve as spare air outlets 6.

[0032] The working principle of this utility model is as follows: A corn harvester harvests corn in the field. The peeling roller on the harvester peels the entire corn ear. The kernels and impurities falling from the corn ear fall into the receiving trough 15 of the receiving mechanism 1 at the peeling roller. The second feeding auger 16 pushes the recovered kernels and impurities down through the leakage holes 15a on the receiving trough 15, into the receiving bin 9 of the recovery feeder 2 below. Simultaneously, the blower 5 starts and blows air outward through the air outlet 6 and air duct 7. The air duct 7 guides the air into the receiving bin 9, and then the air flows through the guide box 13 to the first feeding auger 10. The first feeding auger 10 rotates and conveys the kernels to one side of the transfer cylinder 11. During the conveying process, air is blown out from the guide box 13. The wind blows away impurities such as broken leaves from the grains, and the impurities are discharged outward along the discharge port 14. In this way, most of the impurities can be blown away. At this time, the shaftless conveyor auger 20 also rotates. The grains that enter the transfer cylinder 11 through the feed notch 11a are conveyed by the shaftless conveyor auger 20. The grains are conveyed along the feed hose 18 to the discharge box 19 and fall down. At the same time as the grains fall down, the air blown by the blower 5 is sent out through the air pipe 7 and the air outlet 8. The air blown by the air outlet 8 blows air towards the discharge box 19. At the same time as the grains fall down, the blown air can blow away the remaining impurities mixed in with the grains. Then the clean grains fall into the recycling tank 4. In this way, the recycled grains can be cleaned twice, which can ensure the cleanliness of the grains falling into the recycling tank 4 and save the subsequent impurity removal work.

[0033] In this utility model, the first feeding auger 10, the second feeding auger 16, the shaftless conveying auger 20, and the fan 5 are all linked to the transmission mechanism of the corn harvester through a transmission head and a transmission belt. The specific connection method has been disclosed in the utility model patent with patent number CN202421252753.7 entitled "A Grain Recycling Device and a Corn Harvester with the Device", which discloses a grain recycling device, and will not be repeated here.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
