Description

Technical Field

[0001] The invention relates to the technical field of rapeseed processing equipment, in particular to a hybrid rapeseed breeding male parent removal device. Background Art

[0002] Rapeseed is my country's largest oilseed crop, ranking among the world's largest in both cultivated area and total yield. Rapeseed oil accounts for nearly 50% of domestic vegetable oil production. Rapeseed production plays a crucial role in ensuring the security of China's edible oil supply and safeguarding the lives and health of the people. Seeds are the "chips" of agriculture. To improve the profitability of rapeseed cultivation, new, superior varieties with strong resistance, high oil content, and mechanical harvesting are needed. High-quality rapeseed varieties are generally obtained through hybridization. Typically, a plant with excellent overall quality is selected as the female parent, while a plant with strong resilience, well-developed anthers, abundant pollen, and high quality is selected as the male parent. The male and female parents are typically planted in alternating rows at a specific ratio, allowing the female parent to be fertilized and set seeds by pollen from the male parent, producing hybrid rapeseed seeds.

[0003] In order to ensure the seed purity of rapeseed hybrid seed production, it is usually necessary to remove the male parent in time after the female parent is pollinated. At present, production generally adopts manual uprooting or cutting down, and then manually carrying it to the field. On the one hand, it avoids the seeds formed after the male parent matures from mixing in and affecting the purity of seed production. On the other hand, it can also prevent the male parent from competing for water, fertilizer and nutrients from the female parent plant, affecting the yield of the female parent.

[0004] Manually pulling out, mowing, and transporting rapeseed is labor-intensive and inefficient. With an aging population and rising labor costs, there's an urgent need to mechanize the removal of male parents in rapeseed hybrid breeding. Currently, to improve crop yields, male parents are typically planted in two rows and female parents in six rows, with only about 60cm between female parents on either side of the male row. Currently available small shredders are either too wide to use or the parent parents are intertwined, making small mowers impractical for field use.

[0005] In response to the requirement of cutting off the male parent of narrow rows in hybrid rapeseed breeding, domestic related patents CN218550595U and CN213463000U disclose a male parent cutting and crushing machine for seed rapeseed. The applicant's prior application CN115191245A also discloses a male parent rapeseed crushing machine. The technical ideas of these patents are mainly to separate the hybrid rapeseed breeding male parent and the female parent rapeseed to eliminate the entanglement between the two, and then crush the hybrid rapeseed breeding male parent. The problem with this type of solution is that when separating the hybrid rapeseed breeding male parent and the female parent rapeseed, it will cause damage to the target rapeseed and reduce yield. In addition, the process of crushing the male parent has high power consumption, the machine is not easy to miniaturize, the cutting effect is poor under the condition that the plants are entangled with each other, and the operation efficiency is low.

[0006] Among other crop parent removal machines, patent CN112470692A discloses an intelligent hybrid rice parent pulverizing robot. The robot includes a moving mechanism and a rotary cutting mechanism for rotating, lifting, and cutting the rice. The rotary cutting mechanism includes a blade and a blade guard that perform multiple cuts on the parent to pulverize the parent. While this patent is suitable for pulverizing rice parent plants, it cannot be directly applied to rapeseed parent removal operations due to the distinct characteristics of rice and rapeseed crops. Summary of the Invention

[0007] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a hybrid rapeseed breeding male parent removal device that can effectively treat hybrid rapeseed breeding male parents, has a simple treatment method, low energy consumption and high efficiency.

[0008] Technical solution: To achieve the above-mentioned purpose, the hybrid rapeseed breeding male parent removal device of the present invention comprises a mobile body, a hybrid rapeseed breeding male parent removal mechanism is installed at the front end of the mobile body, and the hybrid rapeseed breeding male parent removal mechanism includes a straw divider and a cutting mechanism;

[0009] The cutting mechanism includes a group of vertical cutting knives and at least one group of horizontal cutting knives, the vertical cutting knives are centrally arranged relative to the horizontal cutting knives, and the vertical cutting knives and the horizontal cutting knives are arranged in a cross shape; it also includes a branch guide plate, the branch guide plate is a V-shaped structure that is narrow in front and wide in the back, and the branch guide plate extends backward from the upper side of the vertical cutting knife.

[0010] Furthermore, the number of the crosscutting knives is two groups, which are upper crosscutting knives and lower crosscutting knives arranged in an upper and lower manner. The branch guide plate is located above the upper crosscutting knives and the lower crosscutting knives.

[0011] The rapeseed planted in the field is planted alternately with 2 rows of hybrid rapeseed breeding father parents and 6 rows of female rapeseed. When removing the hybrid rapeseed breeding father parent, the mobile vehicle moves forward with the hybrid rapeseed breeding father parent removal mechanism, and the vertical cutting knife faces the rows between the 2 rows of hybrid rapeseed breeding father parents. As the mobile vehicle moves forward, the vertical cutting knife cuts the 2 rows of hybrid rapeseed breeding father parents in the middle, separating the entangled branches and leaves between the two, so that the branch guide plate can intervene between the branches and leaves of the 2 rows of hybrid rapeseed breeding father parents, effectively separating the two rows of hybrid rapeseed breeding father parents. On the other hand, for the two rows of hybrid rapeseed breeding father parents that have been cut apart, the upper cross-cutting knife and the lower cross-cutting knife act on the upper end of the stem of the hybrid rapeseed breeding father parent with fewer branches and leaves and the root of the stem respectively, so that the stem part can be cut off and separated from the part with lush branches and leaves of the rapeseed. The part with lush branches and leaves on the upper side of the hybrid rapeseed breeding father parent is still entangled with the branches and leaves of the adjacent female rapeseed. Most of the branches and leaves of the hybrid rapeseed breeding father parent are in a hanging state after the hybrid rapeseed breeding father parent removal device passes through. It is also possible that a small part of the hybrid rapeseed breeding father parent falls to the ground. Since the stem is cut off and falls, the branches and leaves of the hybrid rapeseed breeding father parent can no longer absorb soil nutrients and will naturally wither and fall on the father parent row.

[0012] Compared to the idea of separating and crushing the male parent of hybrid rapeseed breeding from the female parent of rapeseed in the prior art, the present invention completely changes the idea of processing the male parent of hybrid rapeseed breeding. It no longer seeks to separate the male parent of hybrid rapeseed breeding from the female parent of rapeseed and then process the male parent of hybrid rapeseed breeding. Instead, it cuts off the connection between the male parent of hybrid rapeseed breeding and the soil, allowing the branches and leaves of the male parent of hybrid rapeseed breeding to remain in an entangled and crossed state with the female parent of rapeseed, causing them to gradually wither and fall off. Compared to the prior art, the present invention does not need to fully separate the branches and leaves of the male parent of hybrid rapeseed breeding from the female parent of rapeseed, avoiding damage to the female parent of rapeseed during the process of processing the male parent of hybrid rapeseed breeding, which affects the subsequent harvest yield. In addition, the processing method is simpler and more efficient. There is no crushing process, and the machine can travel at a faster speed, with extremely high processing efficiency and low energy consumption.

[0013] Furthermore, the vertical cutter is located in front of the horizontal cutter, and there is a gap between the rear side of the vertical cutter and the front side of the horizontal cutter. In this way, after the vertical cutter has fully cut the branches and leaves of the two rows of hybrid rapeseed breeding parents, and after the branch guide plate has preliminarily separated the two rows of hybrid rapeseed breeding parents, the upper horizontal cutter and the lower horizontal cutter can then perform the stem cutting operation, preventing the horizontal cutter from cutting the stem first and affecting the cutting operation of the vertical cutter. In addition, in order to ensure that the vertical cutter can enter between the two rows of hybrid rapeseed breeding parents, a straw divider is installed at the lower end of the vertical cutter. The straw divider can easily intervene between the stems of the two rows of hybrid rapeseed breeding parents to ensure successful straw division.

[0014] Furthermore, the rear opening of the branch guide plate is greater than the maximum width of the mobile body, and the rear side of the branch guide plate is connected to the front side of the mobile body. In this way, the branch guide plate can make the width of the two rows of hybrid rapeseed breeding father parents separated by a width greater than the maximum width of the mobile body, making it convenient for the mobile body and personnel operating the equipment to pass through.

[0015] Furthermore, the mobile vehicle body includes a frame, and an engine and a traveling mechanism are installed on the frame. The engine can drive the traveling mechanism to operate, and can also drive the vertical cutting knife and the horizontal cutting knife to operate through the driving mechanism.

[0016] Furthermore, the drive mechanism includes a swing ring box, which is connected to the vertical cutter via a pull rod and to the transverse cutter via a swing rod. Specifically, in the height direction, the swing ring box is mounted centrally relative to the upper and lower transverse cutters. The swing ring box has a first output portion that rotates back and forth, and the middle portion of the swing rod is fixed to the first output portion. The upper and lower ends of the swing rod are respectively connected to the upper and lower transverse cutters. In addition, the swing ring box also has a second output portion that rotates continuously, and a connecting rod is rotatably mounted on the second output portion, the ends of which are rotatably connected to the pull rod. The pull rod is L-shaped, with its corner portion connected to the vehicle frame and the pull rod and frame connected via a ball joint. The ends of the pull rod are respectively connected to the connecting rod and the vertical cutter. In this way, the pull rod can convert the movement of the connecting rod into a translational motion that is symmetrical in the vertical direction relative to the ball joint, so that the vertical cutter can operate as required. With this structure, it is possible to simultaneously drive the operation of three groups of cutters: the upper transverse cutter, the lower transverse cutter, and the vertical cutter using a single swing ring box. The vertical cutting knife and the horizontal cutting knife are both existing cutting knife structures, including a fixed knife group and a movable knife group that moves relative to the fixed knife group, which will not be described in detail here.

[0017] Furthermore, the engine is connected to a first pulley, and a second pulley is fixed to the input shaft of the swing ring box; a transition clutch pulley is mounted on the frame; and belts are connected between the transition clutch pulley and both the first and second pulleys. The rotation center of the second output unit is coaxially mounted with the input shaft of the swing ring box. The rotation center of the first output unit is perpendicular to the input shaft of the swing ring box. By controlling the engagement and disengagement of the transition clutch pulley, power transmission and interruption between the engine and the swing ring box can be controlled, facilitating the start and stop control of the hybrid rapeseed breeding male parent removal mechanism.

[0018] Furthermore, the walking mechanism is a triangular crawler assembly, so that the mobile body has a strong walking ability and will not be affected by the ups and downs of the ground and materials such as stems that fall on the ground.

[0019] Furthermore, the frame is provided with a handrail, which can rotate relative to the frame, and a height adjustment mechanism is provided between the handrail and the frame. The staff can use the handrail to assist the machine in turning, and use the operating device on the handrail to perform start and stop control, speed regulation, braking and other operations.

[0020] Furthermore, the row-branching guide plate comprises two left and right halves, the front ends of which are positioned on either side of the vertical cutter. Each half comprises a guide plate body and a fixing plate mounted on the inner side of the guide plate body. This ensures that the row-branching guide plate can be deployed immediately after the vertical cutter separates the hybrid rapeseed breeding parent.

[0021] Beneficial effects: The hybrid rapeseed breeding male parent removal device of the present invention has the following beneficial effects:

[0022] (1) The vertical cutter, horizontal cutter and branch guide plate are rationally arranged, and the vertical cutter and the horizontal cutter are used to cut the stems, so that the male parent of hybrid rapeseed breeding is cut and withered in advance and no effective seeds are formed, which reduces the labor cost of transporting the male parent and reduces the power consumption of the machine.

[0023] (2) The parent parent does not leave the field. The branch guide plate is combined with the vertical cutter to open a path in the parent parent row to facilitate the passage of the machine and the operator. The parent parent is cut by multiple layers of horizontal cutters to avoid the overlap of the rapeseed plants in a single layer, which affects the withering of the parent parent. It is conducive to the natural withering and falling of the parent parent after cutting, achieving the purpose of removing the rapeseed parent without leaving the field and reducing labor intensity. The machine only performs horizontal cutting and vertical cutting. The power consumption of the machine is small. The length of the cutter can be freely customized according to the width of the rapeseed parent row, which is convenient and flexible. The height of the low-level stubble can be controlled by the height adjustment mechanism. The triangular crawler walking parts are used, and the machine can walk independently when walking in a straight line, reducing labor intensity.

[0024] (2) The machine only divides and cuts the parent tree, and moves by squeezing to open a path, which has little impact on the parent tree.

[0025] (3) The horizontal and vertical cutting method is adopted. According to the width of the rapeseed parent row and the height of the rapeseed plant, the horizontal and vertical cutting knives of different lengths can be replaced to meet the requirements of various hybrid rapeseed breeding models, which is convenient and flexible.

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] like Figure 1-2 The hybrid rapeseed breeding father removal device shown includes a mobile body, and a hybrid rapeseed breeding father removal mechanism B is installed at the front end of the mobile body A, and the hybrid rapeseed breeding father removal mechanism B includes a straw divider 5 and a cutting mechanism; the cutting mechanism includes a group of vertical cutting knives 6 and at least one group of horizontal cutting knives, and the vertical cutting knives 6 are centrally arranged relative to the horizontal cutting knives, and the vertical cutting knives 6 and the horizontal cutting knives are arranged in a cross shape; it also includes a branch guide plate 2, and the branch guide plate 2 is a V-shaped structure that is narrow in front and wide in the back, and the branch guide plate 2 starts from the upper side of the vertical cutting knife 6 and extends backward.

[0034] Specifically, if Figure 3 As shown, the branch guide plate 2 includes two left and right half-body structures, and the front ends of the two half-body structures are respectively placed on both sides of the vertical cutting knife 6. Each half-body structure includes a guide plate body 2-1 and a fixed plate 2-2 installed on the inner side of the guide plate body 2-1. In this way, it can be ensured that the branch guide plate 2 can intervene immediately after the vertical cutting knife 6 divides the hybrid rapeseed breeding parent. The rear side opening of the branch guide plate 2 is greater than the maximum width of the mobile body A, and the rear side of the branch guide plate 2 is docked with the front side of the mobile body A. In this way, the branch guide plate 2 can make the width of the two rows of hybrid rapeseed breeding parents separated greater than the maximum width of the mobile body A, which is convenient for the mobile body A and the personnel operating the equipment to pass through.

[0035] Preferably, the number of the crosscutting knives is two groups, which are upper crosscutting knives 3 and lower crosscutting knives 7 arranged in an upper and lower manner. The branch guide plate 2 is located above the upper crosscutting knives 3 and the lower crosscutting knives 7.

[0036] The rapeseed planted in the field is planted alternately with 2 rows of hybrid rapeseed breeding father parents and 6 rows of female rapeseed. When the hybrid rapeseed breeding father parent is removed, the mobile body A moves forward with the hybrid rapeseed breeding father parent removal mechanism B, and the vertical cutting knife 6 faces the rows between the 2 rows of hybrid rapeseed breeding father parents. As the mobile body A moves forward, the vertical cutting knife 6 cuts the 2 rows of hybrid rapeseed breeding father parents in the middle, separating the entangled branches and leaves between the two, so that the branch guide plate 2 can intervene between the branches and leaves of the 2 rows of hybrid rapeseed breeding father parents, effectively separating the two rows of hybrid rapeseed breeding father parents. On the other hand, for the two rows of hybrid rapeseed breeding father parents that have been cut apart, the upper cross-cutting knife 3 and the lower cross-cutting knife 7 act on the upper end of the stem of the hybrid rapeseed breeding father parent with fewer branches and leaves and the root of the stem respectively, so that the stem part can be cut off and separated from the part with lush branches and leaves of the rapeseed. The part with lush branches and leaves on the upper side of the hybrid rapeseed breeding father parent is still entangled with the branches and leaves of the adjacent female rapeseed. Most of the branches and leaves of the hybrid rapeseed breeding father parent are in a hanging state after the hybrid rapeseed breeding father parent removal device passes through. It is also possible that a small part of the hybrid rapeseed breeding father parent falls to the ground. Since the stem is cut off and falls, the branches and leaves of the hybrid rapeseed breeding father parent can no longer absorb soil nutrients and will naturally wither and fall on the father parent row.

[0037] In the above method, compared with the idea of separating and crushing the hybrid rapeseed breeding male parent and the female parent rapeseed in the prior art, the present invention completely changes the idea of processing the hybrid rapeseed breeding male parent, and no longer seeks to separate the hybrid rapeseed breeding male parent from the female parent rapeseed before processing the hybrid rapeseed breeding male parent. Instead, the connection between the hybrid rapeseed breeding male parent and the soil is cut off, and the branches and leaves of the hybrid rapeseed breeding male parent are allowed to remain in an entangled and crossed state with the female parent rapeseed, so that they gradually wither and fall off later. Compared with the prior art, the present invention does not need to fully separate the branches and leaves of the hybrid rapeseed breeding male parent and the female parent rapeseed, avoiding damage to the target rapeseed during the processing of the hybrid rapeseed breeding male parent, which affects the subsequent harvest yield. In addition, the processing method is simpler and more efficient, there is no crushing process, the machine can travel at a faster speed, the processing efficiency is extremely high, and the energy consumption of the machine is low.

[0038] Preferably, the vertical cutter 6 is located in front of the horizontal cutter, and there is a gap between the rear side of the vertical cutter 6 and the front side of the horizontal cutter. In this way, after the vertical cutter 6 has fully cut the branches and leaves of the two rows of hybrid rapeseed breeding parents, and the branch guide plate 2 has preliminarily separated the two rows of hybrid rapeseed breeding parents, the upper horizontal cutter 3 and the lower horizontal cutter 7 can then perform the stem cutting operation to prevent the horizontal cutter from cutting the stem first and affecting the cutting operation of the vertical cutter 6. In addition, in order to ensure that the vertical cutter 6 can enter between the two rows of hybrid rapeseed breeding parents, a straw divider 5 is installed at the lower end of the vertical cutter 6. The straw divider 5 can easily intervene between the stems of the two rows of hybrid rapeseed breeding parents to ensure successful straw division.

[0039] The mobile vehicle A includes a frame 13, on which an engine 1 and a traveling mechanism 11 are mounted. The engine 1 is capable of driving the traveling mechanism 11 and, through the driving mechanism, of driving the vertical cutter 6 and the horizontal cutter. The frame 13 is provided with a handrail 15, which is rotatable relative to the frame 13. A height adjustment mechanism 12 is provided between the handrail 15 and the frame 13. The handrail 15 can be used by a worker to assist the machine in turning, and the operating devices on the handrail 15 can be used to control start and stop, speed, brake, and other operations.

[0040] In this embodiment, the walking mechanism 11 is a triangular crawler assembly, so that the mobile body A has a strong walking ability and will not be affected by the ups and downs of the ground and materials such as stems that fall on the ground.

[0041] like Figure 4-5 As shown, the driving mechanism includes a swing ring box 8, which is connected to the vertical cutting knife 6 through a pull rod 4, and the swing ring box 8 is connected to the transverse cutting knife through a swing rod 14. Specifically, in the height direction, the swing ring box 8 is installed in the center relative to the upper transverse cutting knife 3 and the lower transverse cutting knife 7. The swing ring box 8 has a first output part 8-1, and the first output part 8-1 rotates back and forth. The middle part of the swing rod 14 is fixed on the first output part 8-1, and the upper and lower ends of the swing rod 14 are respectively connected to the upper transverse cutting knife 3 and the lower transverse cutting knife 7. In addition, the swing ring box 8 also has a second output part 8-2, and the second output part 8-2 rotates continuously. A connecting rod 8-3 is rotatably installed on the second output part 8-2, and the end of the connecting rod 8-3 is rotatably connected to the pull rod 4. The pull rod 4 is L-shaped, with its corner portion connected to the frame 13 and the pull rod 4 and the frame 13 connected via a ball joint. The two ends of the pull rod 4 are respectively connected to the connecting rod 8-3 and the vertical cutter 6. In this way, the pull rod 4 can convert the movement of the connecting rod 8-3 into a symmetrical translational movement relative to the ball joint, so that the operation of the vertical cutter 6 meets the requirements. With the above structure, it is possible to simultaneously drive the operation of three groups of cutters, namely the upper cross-cutting knife 3, the lower cross-cutting knife 7 and the vertical cutter 6, through a swing ring box 8. The vertical cutter 6 and the cross-cutting knife are both existing cutter structures, including a fixed knife group and a movable knife group that translates relative to the fixed knife group, which will not be described in detail here.

[0042] The engine 1 is connected to the first pulley 10, and the second pulley 16 is fixed to the input shaft of the swing ring box 8; the transition clutch pulley 9 is installed on the frame 13; and belts are connected between the transition clutch pulley 9 and the first pulley 10 and the second pulley 16. The rotation center of the second output part 8-2 is coaxially installed with the input shaft of the swing ring box 8. The rotation center of the first output part 8-1 is perpendicular to the input shaft of the swing ring box 8. By controlling the engagement and disengagement of the transition clutch pulley 9, the power transmission and interruption between the engine 1 and the swing ring box 8 can be controlled, which facilitates the control of the start and stop of the hybrid rapeseed breeding male parent removal mechanism B.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
