Technical Field

[0001] The utility model relates to the field of corn harvester equipment, in particular to a straw cutting structure for a corn harvester. Background Technique

[0002] At present, a corn harvester is an agricultural machinery used to complete the operation of harvesting corn straw according to agronomic requirements when the corn is mature or nearly mature.

[0003] When a corn harvester is in use, it is necessary to cut the corn straw into pieces by the harvester and then return it to the field on the spot. However, when the corn harvester is working, if there are hard objects such as steel bars on the field, the harvester cannot cut the steel bars during harvesting, which easily causes the cutting blades of the harvester to be damaged by impact. This greatly affects the normal harvesting work of the harvester. Therefore, there is an urgent need for a device to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a straw cutting structure for a corn harvester to solve the problem that when a corn harvester is in use, it is necessary to cut the corn straw into pieces by the harvester and then return it to the field on the spot. However, when the corn harvester is working, if there are hard objects such as steel bars on the field, the harvester cannot cut the steel bars during harvesting, which easily causes the cutting blades of the harvester to be damaged by impact. This greatly affects the normal harvesting work of the harvester as described in the above background technique.

Since the metal detector is located at the front end of the housing through the support frame, when passing through the position of the corn straw, this position is first detected by the metal detector. When steel bars are present at the detected position, they are detected by the metal detector, and then the signal is transmitted to the inside of the controller. The controller controls the cutting mechanism to stop running, and at the same time starts the alarm to give an alarm, prompting the operator that there are steel bars on the ground to prevent the cutting machine from being damaged. After removing the foreign objects, normal harvesting work can be carried out.

The housing guides the corn straw to the position between the housings, and then the straw is cut and crushed by the cutting mechanism. Since the metal detector is located at the front end of the housing through the support frame, when passing through the position of the corn straw, this position is first detected by the metal detector. When there is a steel bar at the detected position, it is detected by the metal detector, and then the signal is transmitted to the inside of the controller.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1-3, the present utility model provides a technical solution: a corn stalk cutting structure for a corn harvester, including a housing 1 and a controller 2. On one side of the controller 2, an alarm 3 is fixedly connected through a power cord, and the alarm 3 is fixed to the cab of the harvester by bolts. On one side of the housing 1, a support frame 4 is fixed by bolts. One side of the support frame 4 is an inclined plane, and a metal detector 5 is fixed to the inclined plane of the support frame 4 by bolts. The metal detector 5 is electrically connected to the controller 2. There is a cutting mechanism on the housing 1 for conveniently cutting the straw. During use, the movement of the harvester drives the movement of the housing 1, and the housing 1 guides the corn straw to the position between the housing 1s, and then the straw is cut and crushed by the cutting mechanism. Since the metal detector 5 is located at the front end of the housing 1 through the support frame 4, when passing through the position of the corn straw, this position is first detected by the metal detector 5. When there is a steel bar at the detected position, it is detected by the metal detector 5, and then the signal is transmitted to the inside of the controller 2. The controller 2 controls the cutting mechanism to stop, and at the same time starts the alarm 3 to alarm, prompting the operator that there is a steel bar on the ground to prevent damage to the cutting machine. After removing the foreign object, normal harvesting work can be carried out.

[0020] In a case of this embodiment, the cutting mechanism includes a first motor 8, a cutting knife 9, a second motor 10, a movable roller 6, a clamping plate 7, a first gear 12, a second gear 11 and a transmission assembly 13. The first motor 8 is fixed to the bottom end of the housing 1 through a mounting bracket, and the cutting knife 9 is fixed to the output end of the first motor 8 through a coupling. The second motor 10 is fixed to one side of the housing 1 through a mounting bracket. The first motor 8 and the second motor 10 are both electrically connected to the controller 2. The output end of the second motor 10 is fixed with a transmission assembly 13 through a coupling. A second gear 11 is welded and fixed to one side of the transmission assembly 13. The movable roller 6 is movably embedded in the housing 1. There are two movable rollers 6. The clamping plate 7 is welded and fixed to the outside of the movable roller 6. The first gear 12 is movably embedded in one side of the housing 1. The first gear 12 is coaxially installed with one side movable roller 6. The first gear 12 meshes with the second gear 11.

[0021] In a case of this embodiment, the transmission assembly 13 includes a transmission belt and transmission wheels. There are two transmission wheels. One side transmission wheel is fixed to the output end of the second motor 10 through a coupling, and the other side transmission wheel is coaxially installed with the other side movable roller 6. During normal use, the first motor 8 and the second motor 10 are started. The first motor 8 drives the cutting knife 9 to rotate, and the second motor 10 drives the second gear 11 to rotate. In this way, the first gear 12 is driven to rotate, so that one side movable roller 6 rotates, and the other side movable roller 6 is driven to rotate through the transmission assembly 13, so that the clamping plate 7 rotates accordingly, so as to clamp the straw and move downward, and then is rotated and chopped by the rotating cutting knife 9, thus completing the crushing work of the straw.

[0022] Working principle: When the utility model is in use, the movement of the harvester drives the movement of the housing 1. The housing 1 guides the corn straw to the position between the housings 1, and then the straw is cut and crushed by the cutting mechanism. Since the metal detector 5 is located at the front end of the housing 1 through the support frame 4, when passing through the position of the corn straw, this position is first detected by the metal detector 5. When there is a steel bar at the detected position, it is detected by the metal detector 5, and then the signal is transmitted to the inside of the controller 2. The controller 2 controls the cutting mechanism to stop running, and at the same time starts the alarm 3 to give an alarm, prompting the operator that there is a steel bar on the ground to prevent damage to the cutting machine. After removing the foreign object, normal harvesting work can be carried out. When in normal use, the first motor 8 and the second motor 10 are started. The first motor 8 drives the cutting knife 9 to rotate, and the second motor 10 drives the second gear 11 to rotate, so as to drive the first gear 12 to rotate, making one side of the movable roller 6 rotate, and driving the other side of the movable roller 6 to rotate through the transmission assembly 13, so that the clamping plate 7 rotates accordingly, so as to clamp the straw and move downward, and then be rotated and shredded by the rotating cutting knife 9, thus completing the crushing work of the straw. It has the advantages of simple structure, convenient use and good use effect.
