Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a mid-season harvester for harvesting multiple cropped rice grains. Background Technology

[0002] Traditional rice harvesters are prone to damaging rice seedlings during operation and cannot adapt to rice seedlings with varying spacing. Furthermore, existing harvesters lack weeding and cultivation functions, making it impossible to loosen the soil and remove weeds during the rice growing season. Therefore, there is an urgent need for an intelligent harvester that can harvest rice seedlings without damaging them and also has weeding and cultivation capabilities. Utility Model Content

[0003] The purpose of this invention is to provide a harvester for multi-crop rice grain harvesting, which can travel between two rows of rice seedlings without damaging them.

[0004] The technical solution adopted by this utility model is:

[0005] A multi-crop rice grain harvester includes a harvester body, wherein the walking mechanism of the harvester body adopts a tracked mechanism, and adopts a double track on the same side, for a total of four tracked mechanisms.

[0006] Each of the track mechanisms includes a track, a drive wheel, a track roller, an auxiliary wheel, and a guide wheel;

[0007] The drive wheel, support wheel, auxiliary wheel, and guide wheel are all connected to the harvester body through their respective axles. The drive wheel, support wheel, auxiliary wheel, and guide wheel are connected by track drive. Each axle is equipped with a locking device, and the corresponding two axles on the two track mechanisms on the same side are equipped with a spacing adjustment device.

[0008] Compared with the prior art, the present invention has the following advantages:

[0009] The new type of inter-row harvester uses a double track design on the same side, allowing it to travel between two rows of rice seedlings without damaging them.

[0010] The new type of tillage harvester can adjust the spacing between the track mechanisms to accommodate rice seedlings with different spacing. Attached Figure Description

[0017] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model will be provided below with reference to the accompanying drawings.

[0018] like Figure 1 The aforementioned harvester for multi-crop unripe rice includes a harvester body 1. The walking mechanism of the harvester body 1 adopts a tracked mechanism 2, and uses a double track on the same side, for a total of four tracked mechanisms 2.

[0019] The spacing between each track mechanism 2 is adjustable to accommodate rice seedlings with different spacing.

[0020] Each of the track mechanisms 2 includes a track 4, a drive wheel 3, a support roller 5, an auxiliary roller 6, and a guide roller 7;

[0021] The drive wheel 3, support wheel 5, auxiliary wheel 6, and guide wheel 7 are all connected to the harvester body 1 via their respective axles 8. The drive wheel 3, support wheel 5, auxiliary wheel 6, and guide wheel 7 are connected by a track 4. Each axle 8 is equipped with a locking device, and a spacing adjustment device is installed between corresponding axles 8 on two track mechanisms 2 located on the same side (such as a spacing adjustment device between the drive wheel 3 axles 8 of two track mechanisms 2, or a spacing adjustment device between the support wheel 5 axles 8 at the same position of two track mechanisms 2, etc.). The distance between the two track mechanisms 2 located on the same side is adjusted by the spacing adjustment device.

[0022] The drive wheel 3, support wheel 5, auxiliary wheel 6 and guide wheel 7 are all fitted with bushings 9 on their axles 8. Each bushing 9 is fitted with a bearing. The outer side of the bearing is used to fit the drive wheel 3, support wheel 5, auxiliary wheel 6 and guide wheel 7. The drive wheel 3 is driven by a motor.

[0023] like Figure 3 , Figure 4As shown, the locking device includes a locking slip 11 and an electromagnetic telescopic device 10; all the outer surfaces of the wheel axles 8 are provided with a ring of external teeth 12, and all the inner surfaces of the bushings 9 are provided with a ring of internal teeth 13. The internal teeth 13 of the bushings 9 mesh with the corresponding external teeth 12 of the wheel axles 8. Multiple conical pits 14 are provided along the axial direction on the tooth ridges of the external teeth 12 of the wheel axles 8. The spacing of the conical pits 14 is 5mm. Each tooth ridge of the external teeth 12 has the same conical pit 14 on the same radial section. The inner side of the locking slip 11 is provided with a pointed cone 15 that mates with the conical pit 14. The locking slip 11 is installed on the electromagnetic telescopic device 10, and the locking slip 11 and the electromagnetic telescopic device 10 are jointly arranged in the mounting groove 16 opened on the inner surface of the corresponding bushing 9. The electromagnetic telescopic device 10 is fixedly connected to the bushing 9.

[0024] When the telescopic end of the electromagnetic telescopic device 10 extends, the pointed cone 15 of the slip 11 inserts into the conical groove 14 of the external tooth 12 of the axle 8, thereby fixing the axle 8 and the bushing 9 relative to each other and placing them in a closed and locked state; and all axles 8 are in a synchronously locked state. When the telescopic end of the electromagnetic telescopic device 10 retracts, the slip 11 opens.

[0025] The electromagnetic telescopic device 10 can be a miniature electromagnetic telescopic device 10, such as an electromagnetic telescopic device, an electromagnetic telescopic rod, or an electromagnetic telescopic iron.

[0026] Each of the aforementioned slips 11 is an arc-shaped slip, and the arc of the slip 11 is the same as the arc of the corresponding axle 8.

[0027] like Figure 5 As shown, each of the spacing adjustment devices includes two electromagnetic telescopic rods 17, which are arranged between two track mechanisms 2 located on the same side. The fixed ends of the two electromagnetic telescopic rods 17 are connected, and the extended ends of the two electromagnetic telescopic rods 17 are respectively connected to the corresponding bushings 9.

[0028] With the cooperation of the locking device, by opening or closing one side of the latch 11, the two electromagnetic telescopic rods 17 are fixed with the closed side as the fixed point. By extending or retracting the electromagnetic telescopic rods 17, the single track mechanism 2 is pushed or pulled laterally to achieve the purpose of spacing adjustment.

[0029] The method for adjusting the spacing between the inner and outer tracks of the two track mechanisms 2 is: synchronous reverse movement.

[0030] While the spacing between the inner and outer tracks on the same side is adjusted, the inner and outer tracks on the other side are also adjusted simultaneously to ensure that the inner and outer tracks on both sides are parallel and equidistant from the centerline of the harvester chassis.

[0031] like Figure 2 As shown, the width H1 of each track mechanism 2 is less than the width between two rows of rice seedlings, ensuring that the track mechanism 2 does not damage the rice seedlings when it travels between the two rows of rice seedlings.

[0032] The width between two rows of rice seedlings can be set according to general dimensions or actual usage dimensions.

[0033] The width H2 between the two track mechanisms 2 located on the same side can span the two rows of seedlings located in the middle.

[0034] The harvester body 1 is equipped with a traction suspension device at its rear end, which connects the soil loosening and weed removal machines. This enables the harvester body 1 to perform the functions of inter-row cultivation to loosen the soil and remove weeds.

[0035] The harvester body 1 uses satellite positioning and navigation, plot planning, laser and optical methods to achieve fully automatic unmanned driving.

[0036] The harvester body 1 adopts an electronically controlled drive and steering system, which improves the accuracy and convenience of operation.

[0037] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
