Technical Field

[0001] The invention belongs to the field of agricultural automation equipment, and in particular relates to a mustard combine harvester. Background Art

[0002] Mustard (scientific name: Brassica juncea (L.) Czern. et Coss.) is an annual herbaceous plant of the genus Brassica, belonging to the family Cruciferae. The stems and leaves of mustard are the main edible parts. The shape of its stems is extremely irregular, and the tumorous stems formed have large differences in size and shape, and the leaves are also relatively large. When the mustard is mature, the leaves will stick to the ground. At present, the harvest of mustard is generally carried out by manpower, including cutting roots, removing leaves, and transportation, which is extremely labor-intensive. After the mustard is harvested, it still needs to be manually packed and transported, which is a large workload and inefficient.

The leaf gathering roller device 2, the clamping and conveying device 3 and the cutting device 4 are arranged in a matching manner. Specifically, the frame 1 includes a support plate 11, a mounting frame 12 and a walking chassis 13. Specifically, in one embodiment, the support plate 11 is arranged parallel to the ground, the driving motor of the whole machine is fixed on the support plate 11, and the support plate 11 is also provided with a seat 111 for users. By setting the support plate 11 parallel to the ground, the user can sit on the seat 111 of the support plate 11 to operate, and the frame structure is simple and easy to use. The walking chassis 13 is a crawler chassis, and the walking chassis 13 is used to drive the whole machine to move. The leaf gathering roller device 2 and the clamping and conveying device 3 are obliquely fixed at the end of the mounting frame 12. The clamping and conveying device 3 includes a pair of conveyor belts 33 docked with the leaf gathering roller device. The pair of conveyor belts 33 cooperate with each other to clamp the mustard transmitted from the mustard conveying channel. The cutting device 4 is installed at the bottom of the clamping and conveying device 3, and is used to cut the roots of the mustard. The transfer device 5 is arranged at the end of the clamping and conveying device 2, and includes an inclined conveyor belt 51, which is used to transport the cut mustard. The leaf gathering roller device 2, the clamping and conveying device 3 and the cutting device 4 are equipped with 2-4 sets. Preferably, in this embodiment, the leaf gathering roller device 2, the clamping and conveying device 3 and the cutting device 4 are equipped with 2 sets, and double rows of mustard can be harvested. This structural method is the best in terms of the balance between the stability of the whole machine assembly and the harvest rate. Of course, in other embodiments, there can also be 3 or 4 sets, and an even number of sets is more preferred.

[0020] Specifically, in one embodiment, the mounting frame 12 includes a fixed crossbar 121 fixed on the support plate 11 and an inclined frame 122 connected to the end of the fixed crossbar 121, and the leaf gathering roller device 2 and the clamping and conveying device 3 are fixed on the inclined frame 122 to form an inclined angle. The leaf gathering roller device 2 and the clamping and conveying device 3 are arranged obliquely. When the whole machine moves forward, the leaf gathering roller device 2 and the clamping and conveying device 3 are arranged obliquely, which can provide a downward and upward force, which is more conducive to the leaf gathering roller device 2 to gather the mustard leaves. And the clamping and conveying device 3 and the leaf gathering roller device 2 work together to smoothly convey the mustard to the rear end.

[0021] Specifically, in one embodiment, the leaf gathering roller device 2 includes symmetrically arranged leaf gathering roller units 21, each leaf gathering roller unit 21 includes a roller 211 and flexible spikes 212 arranged on the roller 211, which are short on the top and long on the bottom and tilted downward, and a plurality of flexible spikes 212 form a conical spike group. During the forward movement of the mustard harvester, the lower longer flexible spikes 212 extend under the mustard stems and leaves through the rotation of the roller 211 and the advancement of the entire machine, and as the roller 211 rotates and the entire machine advances, the upper short spikes contact the stems and leaves, causing the stems and leaves to slowly straighten from a state of hanging to the ground to a cone, thereby achieving the gathering of the stems and leaves and facilitating the entry of the mustard into the clamping and conveying device 3.

[0022] Specifically, in one embodiment, the clamping conveying device 3 is docked with the leaf gathering roller device 2. A pair of conveying belts 33 are arranged opposite to each other in the vertical direction, so that they can cooperate with each other to clamp the mustard greens conveyed from the leaf gathering roller device 2. Preferably, a plurality of flexible arc coils 333 are arranged at intervals on the conveying belt 33. The plurality of flexible arc coils 333 form a certain elasticity and squeezing force, which can better clamp the mustard greens. When the whole machine moves forward, the mustard greens are more easily transported backward along the inclined clamping conveying device 3.

[0023] Specifically, the cutting device 4 is disposed at the bottom of the clamping and conveying device 3. Preferably, the cutting blade of the cutting device 4 is a double disc cutting blade, and the driving motor of the cutting device 4 is fixed on the tilting frame 122 and is located at the bottom of the clamping and conveying device 3.

[0024] Specifically, in one embodiment, the transfer device 5 is fixed on the support plate 11 through a support rod. The transfer device 5 includes an inclined conveyor belt 51, and the width of the conveyor belt 51 is greater than the overall width of the clamping conveyor device 3, so that all the root-cut mustard greens conveyed by the clamping conveyor device 3 can be received and subsequently packed.

[0025] The box transfer device 6 includes a first horizontal conveying device 61 and a second horizontal conveying device 62 which are arranged vertically. The first horizontal conveying device 61 and the second horizontal conveying device 62 are arranged in parallel, and the length of the first horizontal conveying device 61 is smaller than that of the second horizontal conveying device 62. One end of the first horizontal conveying device 61 is arranged at the end of the transfer device 5, and a box pushing mechanism 63 is arranged at one end close to the transfer device 5, and a slide track 64 is arranged on the opposite side of the box pushing mechanism 63; a lifting device 65 is arranged on the side of the other end of the first horizontal conveying device 61. Since the length of the first horizontal conveying device 61 is smaller than that of the second horizontal conveying device 62, and the lifting device 65 is located at the end of the first horizontal conveying device 61, the lifting device 65 can lift the empty box located at the second horizontal conveying device 62 to the first horizontal conveying device 61 during the up and down operation. The first horizontal conveying device 61 receives the box and conveys the box to the bottom of the transfer device 5, receives the mustard greens transferred from the transfer device 5, and when the box is full of mustard greens, the box pushing mechanism 63 pushes the box to move toward the slide track 64, and under the action of gravity, the box full of mustard greens slides out of the frame 1 along the slide track 64.

[0026] The box-moving device 6 also includes a support frame 66, and the first horizontal conveying device 61 and the second horizontal conveying device 62 are fixed on the support plate 11 through the support frame. Specifically, the first horizontal conveying device 61 and the second horizontal conveying device 62 both include conveying rollers. The movement direction of the conveying rollers is to move in the direction where the transfer device 5 is located. Preferably, the box-pushing mechanism 63 is a cam mechanism, including a cam 631 and a driving motor 632 that drives the cam 631 to rotate, and the cam 631 provides a driving force for the box body located in the first horizontal conveying device 61 during the rotation process, and the part of the first horizontal conveying device 61 located between the cam mechanism and the slide track 64 is tilted toward the slide track 64 by the cam mechanism. When the box is full of mustard greens, the cam of the box-pushing mechanism 63 pushes the box body and moves it toward the slide track 64 during the rotation process, and the box body full of mustard greens slides out of the frame along the slide track 64 under the action of gravity.

[0027] Specifically, in one embodiment, the lifting device 65 includes a transmission wheel 651 arranged in the vertical direction and a chain 652 arranged on the transmission wheel 651, and a transmission plate 653 is arranged on the chain 652, and there can be multiple transmission plates 653. During the rotation process, the chain 652 transmits the box located in the second horizontal transmission device 62 to the first horizontal transmission device 61 through the transmission plate 653. In specific operation, the lifting device 65 drives the transmission wheel 651 to rotate through the driving device, thereby driving the chain 652 to operate along the circular path. The empty boxes are manually placed on the second horizontal conveyor 62, and the boxes are moved by the transmission roller. When the transmission plate 653 set on the chain 652 contacts the transmission roller of the second horizontal conveyor 62, the chain 652 stops running, and the boxes move from the second horizontal conveyor 62 to the transmission plate 653. The chain 652 continues to run, driving the boxes to move upward. Since the length of the first horizontal conveyor 61 is shorter than that of the second horizontal conveyor 62, and the lifting device 65 is set at the end of the first horizontal conveyor 61, when the chain 652 drives the transmission plate to approach the transmission roller of the first horizontal conveyor 61, the chain 652 transmits the box to the transmission plate 653. At the turning point of the driving wheel, the conveying plate 653 is inclined at a certain angle toward the first horizontal conveying device 61. Since the driving roller of the first horizontal conveying device 61 is moving, the box is moved from the conveying plate 653 to the driving roller of the first horizontal conveying device 61, and is transported to the bottom of the transfer device 5 to receive the mustard. When the mustard is full, the box pushing mechanism 63 pushes the box to move toward the slide track 64. Under the action of gravity, the box filled with mustard slides out of the frame 1 along the slide track 64, completing the entire mustard harvesting and packing operation. The above-mentioned box moving device 6 has a simple structure and ingenious design. Through the cooperation of various components, the packing of mustard can be successfully completed.

[0028] When the mustard combine harvester is in operation, the mustard greens 2 are gathered by the leaf gathering roller device arranged at the front end. When the mustard combine harvester moves forward, the roller 211 completes the clamping and pulling operations on the mustard greens during the rotation process and applies a forward force, so that the mustard greens enter the clamping and conveying device 3 smoothly, and the mustard greens are root-cut by the cutting device 4 at the bottom of the clamping and conveying device. When the mustard greens are conveyed to the end of the clamping and conveying device 3, the clamping force weakens and falls onto the transfer device 5, entering the boxing and transfer process. During the packing process, the empty box is manually placed in the second horizontal conveyor 62, the second horizontal conveyor 62 moves the box to the vicinity of the lifting device 65, the lifting device 65 lifts the box located at the second horizontal conveyor 62 to the first horizontal conveyor 61, the first horizontal conveyor 61 receives the box and transfers the box to the bottom of the transfer device 5, for receiving the mustard transferred from the transfer device 5, when the box is full of mustard, the box pushing mechanism 63 pushes the box to move toward the slide track 64, and the box full of mustard slides out of the frame along the slide track 64 under the action of gravity. The mustard combine harvester of the present application has a simple structure, and can complete the harvesting and packing operations of mustard, greatly improving the work efficiency and saving labor costs.
