Description

Technical Field

[0001] The invention belongs to the field of agricultural automation equipment, and in particular relates to a double-row mustard harvesting header. Background Art

[0002] Mustard (scientific name: Brassica juncea (L.) Czern. et Coss.) is a member of the cruciferous family, with many species and widespread cultivation. The stems and leaves of leaf mustard are the main edible parts. The shape of its rhizome is relatively sturdy, and there are tumorous stems with large differences in size and shape, and the leaves are also relatively large. When the mustard matures, the leaves will stick to the ground. When mechanical harvesting and cutting is used, problems such as inaccurate cutting positions and troublesome operation often occur.

[0003] CN110731161B discloses a vegetable cleaning device for a multi-row combine harvester of cabbage heads. The upper part of the frame column of the machine is hinged with a leaf clamping and lifting conveying mechanism, which is composed of a loop conveyor belt. The input end and output end of the leaf clamping and lifting conveying mechanism are respectively equipped with a root cutting mechanism and a leaf cutting mechanism; a leaf removing mechanism is installed below the leaf cutting mechanism, and a fork conveying chain moving along the axial direction of the rubber roller toward the output port is installed above the rubber roller of the leaf removing mechanism, and a flat belt lifting device is connected below the output port, and a collecting box is connected below the lifting device. The root cutting mechanism is arranged at the front end, and the position of the root cutting cannot be flexibly adjusted. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies and defects mentioned in the above background technology and to provide a double-row mustard harvesting header with a simple structure and flexible adjustment of the cutting position.

[0005] In order to solve the above technical problems, the technical solution proposed in the present invention is: a double-row mustard harvesting header, comprising: a frame, on which a transmission device is fixed; The elastic bundling device is fixed at one end of the frame, and comprises a bundling frame, and two pairs of tensioning wheel belt assemblies respectively fixed at the front and rear of the bundling frame, and a mustard conveying channel is formed between the two pairs of tensioning wheel belt assemblies; The clamping conveying device is arranged along the length direction of the frame, and includes a pair of conveying belts connected to the elastic contracting device; the pair of conveying belts cooperate to clamp the mustard greens transmitted from the mustard greens conveying channel, and drive the conveying belts to operate through the transmission device; The adjustable cutting device is installed on the frame at the bottom of the clamping conveying device, including a slide rail, a hydraulic motor arranged on the slide rail, a cutting blade fixed on the hydraulic motor, a screw lifter fixed at the bottom of the slide rail, and a driving motor arranged at the end of the screw lifter; The elastic bundling device and the clamping and conveying device are matched with two of them and are used for double-row mustard harvesting.

[0006] In one embodiment, each pair of tensioning wheels includes a tensioning wheel body, a bracket connected to the tensioning wheel body, and the tightening frame includes a vertical connecting rod, and the connecting rod is penetrated at one end of the bracket away from the tensioning wheel body.

[0007] In one embodiment, two rows of roller bundles are symmetrically arranged on the tensioning belts connecting the two pairs of tensioning belt groups in the elastic bundling device, and the roller bundles include a plurality of rollable rollers.

[0008] In one embodiment, a plurality of flexible arc belts are arranged at intervals on the conveyor belt of the clamping conveyor device.

[0009] In one embodiment, the cutting blade disc comprises two double disc cutting blades, the two disc cutting blades of the double disc cutting blade partially overlap and rotate in opposite directions, and each disc cutting blade is equipped with a hydraulic motor.

[0010] In one embodiment, the dual disc cutting blades are located on the center lines of the opposing conveyor belts.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: when the double-row mustard harvesting platform is operating, the elastic contraction device is used to align the mustard rows, and the whole machine moves forward. Since the mustard rhizomes are relatively thick or there is a slight deviation in the rows, the rhizomes touch the tensioning wheel belt group, and the tensioning wheel undergoes elastic deformation, making the channel wider. During the forward movement of the whole machine, the rhizomes enter the mustard conveying channel. At the same time, due to the presence of the tensioning belt, the mustard rhizomes are limited to prevent left and right swings. At the same time, the contraction frame gathers the leaves hanging on the ground from bottom to top, thus completing the elastic contraction of the mustard, so as to facilitate the subsequent clamping and conveying. An adjustable cutting device is set at the bottom of the clamping and conveying device. The height of the cutting knife of the cutter disc can be adjusted by the screw lifter to align with the root position that needs to be cut. For plants of different varieties and under different planting conditions of the same variety and under different planting agronomy, the growth length of their rhizomes and the distance of the stems from the soil are different, but in general, the rhizome conditions (including length, size, distance from the soil, etc.) of plants on a piece of land under the same conditions are roughly the same. By using the double-row mustard harvesting cutter of the present application, the cutting disc is adjusted to a reasonable height according to the specific circumstances of the current operation, thereby meeting the height cutting requirements of the rhizomes of plants in different plots of land, ensuring that the harvested mustard can retain the required stem and leaf parts, and adopting a double-row cutting mode to improve work efficiency.

DETAILED DESCRIPTION

[0014] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively and meticulously below in conjunction with the accompanying drawings and preferred embodiments of the present invention, but the protection scope of the present invention is not limited to the following specific embodiments.

[0015] Unless otherwise defined, all professional terms used below have the same meanings as those generally understood by those skilled in the art. The professional terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the scope of protection of the present invention.

[0016] Unless otherwise specified, various raw materials, reagents, instruments and equipment used in the present invention can be purchased from the market or prepared by existing methods.

[0017] See also Figure 1-3 The double-row mustard harvesting platform of one embodiment is mainly composed of a frame 1, an elastic bunching device 2, a clamping and conveying device 3 and an adjustable cutting device 4, and the elastic bunching device 2, the clamping and conveying device 3 and the adjustable cutting device 4 are matched with two sets for double-row mustard harvesting. Specifically, the frame 1 is a steel structure for supporting the entire harvesting platform, and the elastic bunching device 2, the clamping and conveying device 3 and the adjustable cutting device 4 are all installed on the frame 1. The transmission device of the harvesting platform is arranged and fixed on the top of one end of the frame 1. Specifically, the transmission device includes a hydraulic motor 10 and a corner reducer 12, and the hydraulic motor 10 drives the corner reducer 12 to drive the conveyor belt of the clamping and conveying device 3 to realize the clamping and conveying of the mustard leaves. The elastic bunching device 2 is arranged at the other end of the frame, and the clamping and conveying device 3 is arranged at the middle position of the frame along the length direction of the frame 1. The adjustable cutting device 4 is installed at the bottom of the clamping and conveying device 3, and is also located in the middle position of the length direction of the clamping and conveying device 3.

[0018] Specifically, in one embodiment, the elastic bundling device 2 includes a bundling frame 21, two pairs of tensioning wheel belt groups 22 fixed on the bundling frame 21, and a mustard conveying channel is formed between the two pairs of tensioning wheel belt groups 22. Specifically, the bundling frames 21 are arranged in pairs, that is, two pairs of tensioning wheel belt groups 22 correspond to two bundling frames 21, and the bundling frames 21 include two vertical connecting rods 211 and a connecting cross bar 212 fixed between the two connecting vertical rods 211. The tensioning wheel belt group 22 includes a pair of tensioning wheels 221 with the same structure arranged front and back, and the tensioning wheels 221 arranged front and back are connected by a tensioning belt 222. The tensioning wheels 221 arranged front and back each include a tensioning wheel body 2211, a bracket 2212 connected to the tensioning wheel body 2211, and the vertical connecting rod 211 of the bundling frame 21 is passed through the bracket 2212 at one end away from the tensioning wheel body 2211. One of the vertical connecting rods 211 of the bundling frame 21 is fixed on the tilting frame 122 .

[0019] Preferably, the elastic bundling device 2 also includes two rows of roller bundles 2222 symmetrically arranged on the tensioning belt 222, and the roller bundles 2222 include a plurality of rollable rollers. When the mustard rhizomes pass through the tensioning wheel 221 arranged at the front end and enter the area of ​​the two rows of roller bundles 2222, the sliding friction is converted into rolling friction under the action of the rollers, thereby reducing the resistance of the mustard rhizomes to the forward and backward movement, and reducing the friction between the roots and the elastic bundling device, thereby completing the bundling and transportation of the mustard. At the same time, due to the presence of the tensioning belt 222, the mustard rhizomes are limited to prevent swaying left and right. Therefore, by using the elastic bundling device 2 of the present application, the mustard leaves can be gathered up conveniently and quickly, and quickly transported to the clamping and conveying device 3.

[0020] Specifically, the clamping conveying device 3 is docked with the elastic contracting device 2. Specifically, a pair of conveyor belts 33 cooperate with each other to clamp the mustard transmitted from the mustard conveying channel. Preferably, a plurality of flexible arc coils 333 are arranged at intervals on the conveyor belt 33. The plurality of flexible arc coils 333 are used to form a certain elasticity and extrusion force, so that the mustard can be clamped better. The conveyor belt 33 has a contraction and gathering effect on the leaves of the mustard, and the flexible arc coils 333 on the conveyor belt 33 have a flexible clamping effect on the leaves, thereby reducing damage to the leaves.

[0021] The adjustable cutting device 4 is installed at the bottom of the clamping and conveying device 3, and is used to cut the roots of mustard. The adjustable cutting device 4 includes a slide rail 41, a hydraulic motor 42 arranged on the slide rail 41, a cutting disc 43 fixed on the hydraulic motor 42, a screw lift 44 fixed at the bottom of the slide rail 41, and a drive motor 45 arranged at the end of the screw lift 44. The adjustable cutting device 4 can adjust the height of the slide rail 41 through the screw lift 44, so that the height of the cutting disc 43 arranged on the slide rail 41 in the vertical direction can be adjusted. When operating, the cutting disc 43 can be adjusted to a reasonable height according to the actual situation of the mustard, and the cutting can be carried out at the position where the cutting is required. The hydraulic motor 42 can be translated left and right on the slide rail. After the width of the mustard row spacing is determined, the cutting operation can be carried out after the hydraulic motor 42 is fixed. Preferably, the cutting disc 43 includes two double disc cutting knives, the two disc cutting knives of the double disc cutting knives are partially overlapped and rotated in the opposite direction, and each disc cutting knives is equipped with a hydraulic motor 42. More preferably, each double disc cutting knife is located on the center line of the opposite conveyor belt 33. When the opposite conveyor belt 33 clamps the mustard greens, the mustard greens are naturally located on the center line of the opposite conveyor belt 33, so that the cutting knife disc 43 can more smoothly cut off the mustard greens roots.

[0022] In the present application, when the double-row mustard harvesting platform is in operation, the elastic bundling device 2 is used to align the mustard rows, and the whole machine moves forward. Since the mustard rhizomes are relatively thick or there is a slight deviation in the rows, the rhizomes touch the tensioning wheel belt group 22, and the tensioning wheel 221 undergoes elastic deformation, making the channel wider. During the forward movement of the whole machine, the rhizomes enter the mustard conveying channel. At the same time, due to the presence of the tensioning belt 222, the mustard rhizomes are limited to prevent left and right swinging. The bundling frame gathers the leaves hanging on the ground from bottom to top, thus completing the elastic bundling of the mustard, so as to facilitate the subsequent clamping and conveying. An adjustable cutting device 4 is provided at the bottom of the clamping and conveying device 3. The height of the cutting knife of the cutter disc can be adjusted by the screw lift 44, so as to align with the root position that needs to be cut. For plants of different varieties and under different planting conditions of the same variety and under different planting agronomy, the growth length of their rhizomes and the distance of the stems from the soil are different, but in general, the rhizome conditions (including length, size, distance from the soil, etc.) of plants on a piece of land under the same conditions are roughly the same. By using the double-row mustard harvesting cutter of the present application, the cutting disc is adjusted to a reasonable height according to the specific circumstances of the current operation, thereby meeting the height cutting requirements of the rhizomes of plants in different plots of land, ensuring that the harvested mustard can retain the required stem and leaf parts, and adopting a double-row cutting mode to improve work efficiency.
