Description

Corn harvester arranges miscellaneous device

Technical Field

The utility model belongs to the corn harvester in the technical field of agricultural machinery, and particularly relates to a corn harvester impurity removing device.

Background

When the corn harvester harvests mature corn, a lot of broken corn stems, corn leaves and other weeds can enter the husker or the granary through the ear elevator in the process of picking the corn and then elevating the corn to the corn husker through the ear elevator, so that the husker is blocked and cannot work normally, and the corn husker is damaged due to the blockage. Such failures can account for 30% or even 40% of the failures of corn harvesters, severely impacting the efficiency of corn harvesting. In order to prevent the broken stems, leaves, weeds and the like of the corn straws from entering the corn husker along with the corn ear lift conveyer, Chinese patent 201410091535.4 discloses an impurity removing device of a corn harvester. The impurity removing blower is arranged at the front lower part or the rear lower part of the outlet of the elevator, and then the stem leaves are crushed by adopting a throwing wheel type or hammer claw type or spike tooth type crushing roller and blown out from a grass discharge port by the blower. Such a construction presents a serious problem in that the crushing roller itself is very easily clogged, which is the case with either flail, spiked or hammer claw type. That is to say, the broken stems, stems and leaves are not yet at the position of the corn husker, so that the crushing roller is possibly blocked, a new fault is caused, and the popularization and the application are difficult. Moreover, the blower is used for blowing air, and works in a positive pressure state, so that firstly, the consumed power is large, and secondly, the positive pressure of the blowing air can cause dust raising, and the working environment and quality of the corn harvester are influenced. The fans of other impurity removing devices also operate by taking blast air as main power, and the problems in the invention patents exist. In order to better realize the impurity removal of the corn harvester and keep the normal operation of the corn harvester, the utility model discloses a designer carries out deep research to this, provides the utility model discloses an inventive purpose.

Disclosure of Invention

The invention aims to solve the problem that the corn husker is blocked or even damaged to cause the corn harvester fault when the broken corn stems, stems and leaves, weeds and the like enter the corn husker, and the corn harvester impurity removing device is provided.

The technical solution of the utility model is realized like this, this maize picker arranges miscellaneous device, organism (8) on the casing of lift conveyer (9) have to be installed, the organism is connected with fan casing (1), fan export (7) have on the fan casing, main shaft (2) assemble on the organism through bearing (6), be fixed with a set of sword (3) that move on the characterized by main shaft, should move the sword and mutually support with a set of stationary knife (4) of fixing in organism (8) inside, the rigidity corresponding with fan casing (1) on the main shaft has fan wheel (5).

The utility model discloses a profitable technological effect is: when the corn straw broken rods, stems, leaves, weeds and the like generated after ear picking pass through the device in the running process of the elevator, the corn straw broken rods, the stems, the leaves, the weeds and the like are sucked into the machine body (8) by the air induction effect of the fan and are stirred by the moving knife (3) rotating at a high speed, and the driven knife and the fixed knife are further cut and crushed into finer fibrous objects, so that the corn straw broken rods, the stems, the leaves, the weeds and the like are sucked by the fan impeller and are discharged out of the elevator through the air outlet to be separated from the corn. The trouble that the transmission parts such as guide wheels, guide rollers and the like of the prior corn husker are wound by corn stems and leaves and weeds to lose effectiveness and even are damaged is avoided. Greatly improving the efficiency of the corn harvester and reducing the failure rate. The fault rate caused by blockage is reduced by 20-35% and the peeling efficiency is improved by 10-15% through testing the famous domestic 4YZ-4 type corn harvester.

Detailed Description

The invention will be described in detail with reference to the following embodiments, which are illustrated in the accompanying drawings. Referring to the attached drawings, the corn harvester impurity removing device is provided with a machine body (8) arranged on a shell of an elevator (9), the machine body is connected with a fan shell (1), a fan outlet (7) is formed in the fan shell, a main shaft (2) is assembled on the machine body through a bearing (6), the corn harvester impurity removing device is characterized in that a group of movable cutters (3) are fixed on the main shaft, the movable cutters are matched with a group of fixed cutters (4) fixed in the machine body (8), and a fan impeller (5) is fixed on the main shaft at a position corresponding to the fan shell (1).

In order to meet the installation position requirements of most corn harvesters, the width of the machine body (8) is basically consistent with that of an elevator (9) of the corn harvester, and a fan shell (1) connected with the machine body (8) is arranged on one side of the elevator (9). That is to say, when the organism can be installed in the position on the lift conveyer, the fan casing can be installed in arbitrary one side of lift conveyer both sides, does not all influence the use. The body (8) may be mounted at the front and rear ends of the elevator. However, it should be preferred that the body (8) be mounted as close as possible to the inlet end of the elevator.

For the purposes of uniform specification, convenient installation and use, the axis of the main shaft (2) assembled on the machine body (8) through the bearing (6) is vertical or basically vertical to the movement direction of the elevator (9) of the corn harvester. The installation form can utilize the wind energy of the fan and the matching between the movable knife and the fixed knife to the maximum extent, and effectively cut and crush the attracted impurities. The number of the fixed cutters and the movable cutters can be determined according to the width of the elevator, the common fixed cutters comprise 3 groups, the movable cutters comprise 5 groups, the use requirement can be met, more power is consumed, and the cutting-off and crushing effect is poor. Like this, stationary knife and move the sword and mutually support, cut and smash completely, and maize stem leaf stalk and leaf disconnected pole etc. can cut up into shorter fibre, through the effect separation of induced air, discharge through the fan export, can not the adhesion on stationary knife and move the sword, consequently be difficult for causing the jam. Certainly, the contour line of the cutter shaft can be parallel to or crossed with the movement direction of the elevator, and the angle of the fan shell needs to be adjusted by adopting the technical scheme, so that the outlet (7) of the fan can smoothly discharge the cut and crushed corn, weed fiber and other sundries.

In order to improve the efficiency and reduce dust, the fan formed by the fan shell (1) and the fan impeller (5) is an induced draft fan. Of course, the use of a blower is also possible, and the requirements of cutting and crushing can be completely met, but the energy consumption of the blower and the generated dust are relatively large, so that the use of the blower is generally not recommended.

The outlet of the fan is sleeved with a proper filter bag, and the discharged impurities such as stalks, stems and leaves, weeds and the like are collected at regular time, so that the dustless operation can be realized. Certainly, the straw can be directly discharged to a corn field for field operation, and the straw is returned to the field. The utility model discloses a arrange miscellaneous device has very big practical value and popularization and application and worth.

It should be noted that: if the original corn harvester is modified, the sealing top cover of the joint of the elevator and the device is removed (if the sealing top cover is provided) so as to be beneficial to smoothly installing and debugging the device.
