Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, and specifically refers to a machine for returning pollinated male rice to the field. Background Technology

[0002] Hybrid rice seed production is a key agricultural technology to ensure high and stable rice yields. This process involves transferring pollen from the male rice parent to the female rice parent to produce seeds with hybrid vigor. After pollination, the male rice plant needs to be removed from the field promptly to avoid affecting the subsequent growth of the female rice, ensuring proper ventilation and light penetration, facilitating concentrated nutrient supply, field management, and harvesting.

[0003] Currently, the common methods for handling male parent rice after pollination are manual harvesting or harvesting with general-purpose harvesting machinery. Clearly, both methods have the following drawbacks: First, manual harvesting of male parent rice in the field is not only slow and costly, but also difficult to complete on time in large-scale seed production bases. Missing the optimal time for returning the rice to the field directly affects the growth of the female parent rice. Second, general-purpose harvesting machinery is relatively bulky, while hybrid rice seed production fields have specific requirements for row and plant spacing between male and female parents, requiring specialized structures. The inflexibility of general-purpose harvesting machinery can easily cause crushing damage to the female parent rice. Furthermore, existing general-purpose harvesting machinery is complex, with high purchase and maintenance costs, making its use for harvesting only the male parent uneconomical. Summary of the Invention

[0004] The purpose of this invention is to provide a machine for returning pollinated male rice to the field. The machine is compact, flexible in steering, and inexpensive. It can efficiently and accurately cut and crush the male rice rows and return them to the field, avoiding damage to the female rice.

[0014] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —3: A rice pollination and subsequent rice mulching machine includes a frame 1. The bottom of the frame 1 is equipped with a walking mechanism for traversing the field. A control handle 2 is located at the rear of the frame 1, and a cutting mechanism for cutting the male parent rice grains is located at the front. A power assembly 3 and a gearbox assembly 4 are fixed to the frame 1. A drive pulley 5 and a cutting drive sprocket 6 are mounted on the output shaft of the power assembly 3. A cutting driven sprocket 7, which is driven by a chain and connected to the cutting drive sprocket 6, is mounted on the input shaft of the cutting mechanism. A driven pulley 8, which is driven by a synchronous belt and connected to the drive pulley 5, is mounted on the input shaft of the gearbox assembly 4. The output shaft of the gearbox assembly 4 is connected to the input end of the walking mechanism. Thus, the operator only needs to control the direction of travel of the walking mechanism from the rear of the frame 1 using the control handle 2 to enable the rice mulching machine to move and flexibly turn in the working field.

[0015] This utility model features a compact and flexible machine body with low cost. The power assembly 3 provides power to both the walking mechanism and the cutting mechanism. It has simple functions and stable and reliable transmission, and can efficiently and accurately cut and crush the male rice rows and return them to the field, avoiding damage to the female rice.

[0016] The traveling mechanism can be a tracked wheel assembly commonly used in the art. In this embodiment, the traveling mechanism includes a traveling wheel 9, which is rotatably mounted on the frame 1 via a traveling shaft. One end of the traveling shaft is connected to the output shaft of the gearbox assembly 4. Furthermore, in order to ensure that the powertrain 3 provides sufficient transmission torque to the traveling wheel 9, the transmission structure of the gearbox assembly 4 also includes the following deceleration and torque increase transmission structure: a traveling drive sprocket 10 is mounted on the output shaft of the gearbox assembly 4, an intermediate drive shaft is rotatably connected to the frame 1, an intermediate drive sprocket 11 and an intermediate driven sprocket 12 are mounted on the intermediate drive shaft, and a traveling driven sprocket 13 is mounted on the corresponding end of the traveling shaft. The traveling drive sprocket 10 is connected to the intermediate drive sprocket 11 via a chain, and the traveling driven sprocket 13 is connected to the intermediate driven sprocket 12 via a chain. The outer diameter of the traveling drive sprocket 10 is smaller than the outer diameter of the intermediate drive sprocket 11, the outer diameter of the intermediate drive sprocket 11 is larger than the outer diameter of the intermediate driven sprocket 12, and the outer diameter of the intermediate driven sprocket 12 is smaller than the outer diameter of the traveling driven sprocket 13.

[0017] Meanwhile, in order to enable the machine to move smoothly in the field, the walking mechanism also includes a sliding base plate 14, which is provided in two parallel locations on the frame 1 behind the walking wheels 9.

[0018] To prevent the harvesting mechanism from splashing backward during the harvesting, crushing, and returning of the parent rice to the field, the cutting mechanism includes a cutting protective cover 15 mounted on the machine housing, with its opening facing forward and tilted downward. Correspondingly, a cutting shaft 16 arranged laterally is rotatably connected to the cutting protective cover 15. Several cutting blades 17 are evenly distributed along the axial direction on the outer wall of the cutting shaft 16. One end of the cutting shaft 16 extends beyond the cutting protective cover 15 and is fitted with the cutting driven sprocket 7. Thus, when the cutting blades 17 rotate with the cutting shaft 16 to cut and crush the parent rice, the cutting protective cover 15 can effectively prevent the cut and crushed parent rice from splashing backward. Furthermore, in this embodiment, the cutting blades 17 are serrated blades commonly used in rice returning machines.

[0019] In addition, to assist the machine in moving and cutting along the rows of parent rice, a rice-supporting bracket is provided at the front end of the cutting protective cover 15. This bracket consists of two parallel rice-supporting side tubes 18 and a transverse connecting pipe 19 connecting the two rice-supporting side tubes 18. The rear ends of the two rice-supporting side tubes 18 are respectively fixed to the left and right side walls of the cutting protective cover 15. That is, a guide gap is formed between the front ends of the two rice-supporting side tubes 18 to guide the parent rice in the same row into the cutting mechanism.

[0020] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
