Description

Technical Field

[0001] The utility model relates to the technical field of corn harvesters, in particular to a residual material re-screening and recovery mechanism for corn harvesters. Background Art

[0002] A corn harvester is an agricultural machine that mechanically removes mature corn ears, stacks them, and returns the stalks to the field all at once. The process: The corn harvester removes ears while the corn is still growing (known as standing stalk picking). The picking rollers and picking plates break the stalks. Due to the height difference between the inner and outer picking rollers, the ears fall into an ear box. Once the box is full, the ears are unpacked and stacked. A high-speed cutter severs the stalks at the base, which are then crushed into 3-5 cm long pieces by a comminution mechanism. After shredding, the stalks fall naturally to the ground. Then the ears are transported to the field, peeled with a peeling machine, and threshed after drying. After searching, the patent with publication number CN116806558A discloses a corn harvester's residual tailings screening and recovery mechanism assembly, including a peeling component, a cleaning mechanism and a grain impurity removal fan. The peeling component is arranged on the upper side of the impurity removal and cleaning mechanism, and a recovery hopper is arranged below the screening and impurity removal and cleaning mechanism. A grain impurity removal fan is arranged on the side of the impurity removal and cleaning mechanism. The impurity removal and cleaning mechanism includes a conveying scraper mechanism and a screen. The screen is arranged below the conveying scraper mechanism. There are multiple groups of sieve holes on the screen, which are divided into small sieve hole area, large sieve hole area, strip hole area and tail sieve hole area from the screening direction. The outer side of the tail sieve hole area is arranged The re-screening mechanism is fixedly installed on the screen mesh. The re-screening mechanism is composed of several groups of elastic comb teeth. The elastic comb teeth are made of highly elastic material. They vibrate along with the impurity removal and cleaning mechanism, and rebound the fruits that fall on the re-screening mechanism to the impurity removal and cleaning mechanism, so that the residual fruits fall into the hopper at the bottom or rebound to the screening mechanism for screening, thereby improving the screening accuracy. However, its structure is complex and the manufacturing cost is high. At the same time, in actual use, the probability of damage and the subsequent maintenance cost and time are high. For this reason, a re-screening and recovery mechanism of residual tailings of corn harvesters with a simple structure is designed to ensure the recovery of corn kernels while reducing the probability of damage during use and the subsequent maintenance cost and maintenance time, thereby reducing the manufacturing cost and being suitable for promotion.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the utility model provides a residual material re-screening and recovery mechanism for a corn harvester, which has the following beneficial effects:

[0014] The residual tail material re-screening and recovery mechanism of the corn harvester is convenient for conveying the straw blown out from the rear of the corn harvester to the side of the inclined guide plate by setting an upper conveyor belt, and then sliding into the arc structure at the bottom through the inclined guide plate. The straw falling into the arc structure can be turned over by the material-dividing and grain-leaching component in the arc structure, and the corn kernels wrapped therein can be leached out and then fall into the arc structure and fall into the recovery trough below through multiple arc structures at the bottom of the arc structure. The straw is then thrown out from the other side of the arc structure and passes through the grain-leaching gap to avoid the material-dividing and grain-leaching component diverting the corn kernels from the arc structure, ensuring that all the corn kernels pass through multiple sieve holes and fall into the recovery trough below. The overall structure is simple, the manufacturing cost is low, and the subsequent maintenance is also convenient. The residual tail material re-screening and recovery mechanism of the corn harvester has a simple structure, which ensures the recovery of corn kernels while reducing the probability of damage during use, the subsequent maintenance cost and the maintenance time, thereby reducing the manufacturing cost and being suitable for promotion.
