Description

Technical Field

[0001] This invention relates to the field of corn harvester grain recovery technology, specifically to a grain recovery device. Background Technology

[0002] Currently, among my country's three major grain crops, the mechanized harvesting rate for wheat has reached over 90%, and for rice it is around 70%-80%. However, the mechanized harvesting rate for corn is less than 70%, a significant difference. The dominant method for mechanized corn harvesting in my country is still ear harvesting. Due to significant differences in corn agronomy and the physical characteristics of the crop across different regions, corn harvesting cannot be achieved domestically across regions using a single harvester structure, unlike wheat and rice. It is precisely because cross-regional operations have brought better harvesting benefits to harvester owners that the sales of wheat and rice harvesters have increased significantly, naturally leading to a rapid increase in the mechanized harvesting rate.

[0003] The main agronomical issues with maize lie in the significant differences in harvest conditions across different regions, and the substantial variations in moisture content at harvest between different maize varieties and in different regions. A prominent problem is that maize harvesting in the Huang-Huai-Hai region needs to be balanced with wheat-maize rotation, requiring timely harvesting. Consequently, maize harvesting is generally earlier to allow time for wheat rotation planting. Therefore, in the Huang-Huai-Hai region, maize is typically harvested while still green, at the waxy maturity stage, resulting in high moisture content. During the ear-peeling process, the kernels that fall are highly moist and cannot be directly returned to the grain storage; they must be stored in kernel collection bins. However, the high moisture content of the maize kernels makes them difficult to remove from these bins, impacting operational efficiency. In contrast, in single-season maize growing areas in the Northwest and Northeast, harvesting is generally done at full maturity, when the maize is already nearly mature with low moisture content. Kernels that fall during ear-peeling can be directly returned to the ear bins, avoiding secondary unloading.

[0004] Depending on the different corn planting techniques in various regions, corn harvesters are equipped with various types of kernel recovery devices: drawer type, mechanical kernel unloading, and kernel lifting and recovery bins. These cannot meet the needs of users in different regions, cannot achieve cross-regional operations, and result in low user profits. Although there are also kernel recovery devices that can unload kernels and return them to the ear box, when the kernel moisture content is high, the kernels tend to solidify in the recovery bin, making unloading difficult, and still cannot meet the needs of users in different regions. Summary of the Invention

[0005] The purpose of this invention is to provide a grain recycling device that can directly return grains to the ear box and quickly unload them from the grain recycling box, thus meeting the different requirements for grain processing methods in different regions.

[0006] To achieve the above objectives, this invention discloses a grain recycling device, including a grain recycling bin and a grain elevator located outside the grain recycling bin. A grain conveying device is installed inside the grain recycling bin, with the lower end of the grain elevator connected to the grain output end of the grain conveying device. The grain conveying device includes a grain conveying opening and closing door located at its upper part. When the grain conveying opening and closing door is fully open, all the grains pass through the top of the grain recycling bin and enter the grain conveying device. When the grain conveying opening and closing door is closed, a grain recycling gap is left between the grain conveying device and the side wall of the grain recycling bin, and the grain conveying device is closed within the grain recycling bin. When it is necessary to return the grains to the ear box, the grain conveying opening and closing door is opened, the grains enter the grain conveying device and are conveyed by the grain conveying device to the grain elevator, and then enter the ear box through the grain elevator. When it is necessary to store the grains in the grain recycling bin, the grain conveying opening and closing door is closed, and the grains enter the grain recycling bin through the grain recycling gap. It can easily meet the requirements of different grain processing methods.

[0007] Preferably, the grain conveying device is installed in the grain recycling box in the front-to-back direction. The grain conveying device also includes a grain conveying bottom shell located below the grain conveying opening and closing door. The front and rear sides of the grain conveying bottom shell are connected to the front and rear inner side walls of the grain recycling box and the opening is set upward.

[0008] Preferably, the grain conveying opening and closing door includes two grain conveying opening and closing door plates located on the left and right sides respectively. The lower sides of the two grain conveying opening and closing door plates are respectively hinged to the left and right sides of the grain conveying bottom shell. When the grain conveying opening and closing door is fully open, the upper sides of the two grain conveying opening and closing door plates are respectively connected to the left and right side walls of the grain recycling box. When the grain conveying opening and closing door is fully closed, the upper sides of the two grain conveying opening and closing door plates are connected and the connection is closed. Using two grain conveying opening and closing door plates respectively hinged to the two sides of the grain conveying bottom shell makes the structure simple and can easily realize the opening and closing of the grain conveying opening and closing door.

[0009] Preferably, the front end and / or rear end of the grain conveying gate are provided with a grain recycling sliding component, and the side wall of the grain recycling box is provided with an arc-shaped grain recycling groove that matches the grain recycling sliding component. This makes the opening and closing of the grain conveying gate convenient and simple.

[0010] Preferably, the grain recycling sliding component includes a sliding component fixing part fixedly connected to the grain conveying opening and closing door plate and a sliding component adjusting part extending out of the grain recycling box from the grain recycling chute. The sliding component adjusting part makes operation more convenient.

[0011] Preferably, two sliding component fixing grooves are respectively provided on the outer wall of the grain recycling box near both ends of the grain recycling chute. The sliding component adjustment part can be respectively engaged in the two sliding component fixing grooves at both ends of the grain recycling chute. The setting of the sliding component fixing grooves improves the stability of the invention in use.

[0012] Preferably, the upper middle part of the grain collection box is provided with a crossbeam for the opening and closing door arranged in the front-to-back direction. When the grain conveying opening and closing door is fully closed, the upper sides of both grain conveying opening and closing door plates abut against the crossbeam. This improves the sealing performance at the connection point of the upper sides of the two grain conveying opening and closing door plates, ensuring that all grains passing through the connection point of the two grain conveying opening and closing door plates can be separated into the grain collection box.

[0013] Preferably, the upper ends of the left and right side walls of the grain collection box are respectively provided with two opening and closing door side beams arranged in the front-to-back direction. When the grain conveying opening and closing door is fully opened, the upper sides of the left and right grain conveying opening and closing door plates abut against the left and right opening and closing door side beams respectively. Similarly, this improves the sealing performance of the connection between the upper sides of the grain conveying opening and closing door plates and the side walls of the grain collection box, ensuring that all grains passing through the connection between the grain conveying opening and closing door plates and the side walls of the grain collection box can be guided into the grain conveying device.

[0014] Preferably, the grain conveying device further includes a grain conveying auger located above the grain conveying bottom shell and below the grain conveying opening and closing gate. The grain conveying auger is arranged in a front-to-back direction, and the grain conveying bottom shell has a V-shaped cross-section with a rounded bottom transition. The grain conveying auger can stably convey the grain in the grain conveying device to the grain elevator, effectively preventing grain solidification and improving the recovery efficiency of the recycling device.

[0015] Preferably, the grain recycling bin has an outwardly extending grain outlet channel on the right side, and a grain ear bin is located below the grain outlet channel.

[0016] In summary, the beneficial effects of this invention are as follows: When it is necessary to return the grains to the ear box, the grain conveying gate is opened, the grains enter the grain conveying device and are conveyed to the grain elevator, and then enter the ear box via the grain elevator; when it is necessary to store the grains in the grain recycling box, the grain conveying gate is closed, and the grains enter the grain recycling box through the grain recycling gap, easily meeting the requirements for different grain processing methods; the grain conveying auger can stably convey the grains in the grain conveying device to the grain elevator, effectively preventing grain solidification and improving the recycling efficiency of the recycling device; the sliding component adjustment part makes operation more convenient; the middle crossbeam of the opening gate ensures that the grains can completely enter the grain recycling box; the side crossbeams of the opening gate ensure that all the grains are guided into the grain conveying device.
