Description

Technical Field

[0001] This utility model relates to the technical field of sugarcane harvesting equipment, specifically to a sugarcane harvesting and conveying mechanism and a harvester. Background Technology

[0002] Sugarcane is one of the important economic crops in southern my country. The sugar content of sugarcane stalks is as high as 55%-70%, and the sugar produced from it plays an important role in our production and daily life. In addition, the bagasse after processing is also a good raw material for brewing and papermaking.

[0003] Currently, when small sugarcane harvesters deliver sugarcane from the conveyor to the ground, the direction in which the sugarcane lands is quite random, resulting in an uneven arrangement on the ground. This affects the efficiency of subsequent sugarcane collection and loading, and further improvements are needed. Summary of the Invention

[0004] The present invention aims to provide a sugarcane harvesting and conveying mechanism. This device, through a uniquely designed guide wheel, can influence the direction in which the sugarcane falls and is arranged on the ground when it is delivered, so that it is neatly arranged on the ground, thereby improving the efficiency of sugarcane collection and loading.

The upper conveying device is equipped with a guide wheel on one side of the sugarcane outlet. The guide wheel is provided with multiple sets of guide teeth evenly spaced along its outer circumference. The ends of the guide teeth extend to the other side of the sugarcane outlet.

[0009] The guide teeth are provided in 4-6 sets.

[0010] The upper conveying device includes a drive device I, a drive device II, a front support plate, a rear support plate, an upper actuating sprocket I, an upper actuating sprocket II, an upper rotating chain I, an upper rotating chain II, an upper pawl I, and an upper pawl II; the front support plate and the rear support plate are respectively installed on one side of the frame and are distributed at intervals, and the area between the front support plate and the rear support plate is the conveying channel;

[0011] The front end of the front support plate is equipped with a set of upper sprockets I via sprocket shaft I, and the rear end of the front support plate is equipped with a set of upper sprockets I via sprocket shaft II. A rotating chain I is wound between the two sets of upper sprockets I, and multiple sets of upper claws I are evenly spaced on the outer surface of the upper rotating chain I. The driving device I is connected to the sprocket shaft I, driving the sprocket shaft I to rotate, thereby driving the upper rotating chain I and the upper claws I on it to rotate.

[0012] The front end of the rear support plate is equipped with a set of upper sprockets II via a driven shaft, and the rear end of the rear support plate is equipped with a set of upper sprockets II via a sprocket shaft IV. A rotating chain II is wound between the two sets of upper sprockets II, and multiple sets of upper claws II are evenly spaced on the outer surface of the upper rotating chain II. The driving device II is connected to the driven shaft, drives the sprocket shaft III to rotate, and then drives the upper rotating chain II and the upper claws II on it to rotate.

[0013] Both drive device I and drive device II are electric motors;

[0014] The output shaft of drive device I is connected to sprocket shaft I via a coupling; the output shaft of drive device II is connected to the driven shaft via chain drive.

[0015] Guide rod I and guide rod II are respectively installed on the top surfaces of the front support plate and the rear support plate via brackets, and the guide rod I and guide rod II form a flow channel corresponding to the lower conveying channel.

[0016] The lower conveying device includes a lower support plate, a lower guide rod, a lower actuating sprocket, a lower transmission chain, and a lower pawl; the lower support plate and the lower guide rod are respectively installed on the frame, the lower support plate is located directly below the rear support plate, the lower guide rod is located below the front support plate, and the area between the lower support plate and the lower guide rod is the conveying channel;

[0017] The lower end of the driven shaft extends into the rear support plate, on which a set of lower sprockets are installed. A set of lower sprockets is installed at the rear end of the rear support plate through sprocket shaft V. A lower drive chain is wound between the two sets of lower sprockets. Multiple sets of lower pawls are evenly spaced on the outer surface of the lower drive chain.

[0018] A load-bearing support plate is installed on the bottom of the frame below the sugarcane outlet to support the bottom of the sugarcane.

[0019] This utility model also discloses a sugarcane harvester that utilizes the aforementioned sugarcane harvesting and conveying mechanism; it further includes a sugarcane-supporting mechanism and a cutting mechanism. The sugarcane-supporting mechanism comprises two sets, each located at the front end of the frame, arranged in a trumpet-shaped opening structure. A sugarcane channel is located between the two sets of sugarcane-supporting mechanisms, with its upper end connected to the sugarcane inlet at the front end of the conveying channel. The cutting mechanism is located at the bottom of the frame, below the upper end of the sugarcane-supporting mechanism. A traveling mechanism is also included, with the entire frame mounted on it.

[0020] The sugarcane supporting mechanism and the cutting mechanism can use existing general structures, such as the technology described by the inventor in the patent "A sugarcane harvesting device 2024224992296", or the technology described in the prior art patent "Harvesting disc, control method of harvesting disc and sugarcane harvester 202211207257.5".

[0021] A cutting mechanism is provided at the bottom of the front side of the frame.

[0022] The working principle of this utility model is as follows:

[0023] Sugarcane is conveyed towards the sugarcane outlet by the conveyor mechanism. Upon reaching the outlet, it contacts the guide teeth of the guide wheel, causing the guide wheel to rotate. Guided by the guide wheel and guide teeth, the sugarcane falls in the same direction, thus automatically achieving a neat arrangement of sugarcane on the ground. In a preferred configuration, the conveyor channel near the outlet is a straight channel running left-right, perpendicular to the harvester's forward direction. This utilizes the forward inertia to better coordinate with the guide wheel guidance, ensuring the sugarcane is arranged in a left-right direction, further facilitating subsequent sugarcane collection and loading operations.

[0024] This utility model, through its uniquely designed guide wheel and guide teeth, can effectively achieve a neat arrangement of sugarcane after harvesting on the ground, greatly facilitating subsequent sugarcane collection and loading operations, improving the efficiency of sugarcane harvesting, and has good application prospects.
