[0013] A control method for a seed supply system of a sugarcane horizontal planter comprises the following steps:

[0014] (1) The controller controls the power motor to start, and the sugarcane seed conveyor belt starts to rotate. The controller uses the torque data fed back by the torque sensor to determine the status of sugarcane seed conveying and lifting on the sugarcane seed conveyor belt. When the torque gradually increases, it means that the amount of sugarcane seeds on the conveyor belt is gradually increasing and the lifting efficiency is gradually decreasing. At this time, the controller controls the sugarcane seed conveyor belt to reduce the running speed, and controls the lifting mechanism to drive the sugarcane storage push plate to flip downward to reduce the amount of sugarcane seeds fed to the sugarcane seed conveyor belt. When the torque is reduced to the no-load torque, it means that the amount of sugarcane seeds on the sugarcane seed conveyor belt is too small. The controller controls the running speed of the sugarcane seed conveyor belt to increase, and controls the lifting mechanism to drive the sugarcane storage push plate to flip upward to dump the sugarcane seeds onto the sugarcane rake lifting section. When the torque suddenly increases, it means that the sugarcane seeds are blocked or the mechanism fails. The controller immediately controls the seed supply system to shut down and sends an alarm signal.

[0015] (2) The controller determines the amount of sugarcane seeds piled up on the sugarcane rake lifting section by using the sugarcane seed accumulation height information fed back by the first distance measuring sensor; when the amount of sugarcane seeds is lower than the set value, the controller controls the lifting mechanism to drive the sugarcane storage push plate to flip upwards and dump the sugarcane seeds onto the sugarcane rake lifting section; when the amount of sugarcane seeds reaches the set value, the controller controls the lifting mechanism to stop lifting or stopping descending; when the amount of sugarcane seeds exceeds the set value, the controller controls the lifting mechanism to drive the sugarcane storage push plate to flip downwards; at the same time, the controller adjusts the speed of the power motor according to the sugarcane seed accumulation height information fed back by the first distance measuring sensor, thereby adjusting the running speed of the sugarcane seed conveyor belt, thereby maintaining the stability and efficiency of the supply of seeds on the sugarcane seed conveyor belt;

[0016] (3) When too much sugarcane seeds are piled up on the sugarcane seed conveyor belt, the height of the sugarcane sorting plate will be raised higher. The controller determines the amount of sugarcane seeds piled up on the sugarcane seed conveyor belt through the distance change information fed back by the second distance measuring sensor, thereby controlling the running speed of the sugarcane seed conveyor belt and the lifting height of the lifting mechanism to maintain the stability of the amount of sugarcane seeds on the sugarcane seed conveyor belt;

[0017] (4) During the operation of the sugarcane seed conveyor belt, the controller uses the information fed back by the photoelectric sensor to determine whether there are sugarcane seeds that are lifted out of order on the sugarcane seed conveyor belt. When the photoelectric sensor detects the presence of out-of-order sugarcane seeds, the controller controls the out-of-order sugarcane removal mechanism to remove the out-of-order sugarcane seeds to ensure the seed supply quality of the seed supply system.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Each link of the seed supply system of the present invention is measurable and controllable, with a high degree of automation, which reduces the number of manual labor requirements and improves work efficiency. In the process of the lifting mechanism driving the sugarcane storage push plate to transport the sugarcane seeds to the sugarcane seed conveyor belt, a first distance measuring sensor detects the number of sugarcane seeds on the sugarcane rake lifting section. In the process of transporting the sugarcane seeds from the sugarcane seed conveyor belt, a sugarcane sorting plate performs preliminary sorting on the transported sugarcane seeds, and sorts the sugarcane seeds from disorder to a majority of ordered states, which has a great effect on improving the efficiency of sugarcane seed supply. The sugarcane seeds on the sugarcane seed conveyor belt are reflected according to the up and down movement state of the sugarcane sorting plate, and then the running speed of the sugarcane seed conveyor belt and the working state of the lifting mechanism are controlled. The disordered sugarcane rejecting mechanism can solve the disordered lifting phenomenon of sugarcane seeds in the process of lifting the sugarcane seed conveyor belt, such as vertical, so as to ensure the quality of seed supply.

DETAILED DESCRIPTION

[0025] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0026] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

The seed supply system A includes a sugarcane seed conveyor belt 4, a sugarcane storage push plate 1, a lifting mechanism 2, a first distance measuring sensor 3, a torque sensor 5, a sugarcane sorting plate 6, a second distance measuring sensor 7, a photoelectric sensor 8, a disordered sugarcane removal mechanism 9 and a controller (not shown).

[0028] refer to Figure 1 The sugarcane seed conveyor belt 4 is driven by a power motor to rotate. A plurality of evenly distributed sugarcane baffles 44 are provided on the outer side of the sugarcane seed conveyor belt 4 along its length direction, which are used to rake sugarcane and lift and transport sugarcane seeds. The sugarcane seed conveyor belt 4 is triangular in shape, and the front side of the sugarcane seed conveyor belt 4 is in an upward trend from front to back as a whole, which is convenient for lifting and sorting sugarcane seeds. The lower end of the front side of the sugarcane seed conveyor belt 4 is a sugarcane rake lifting section 41, and the sugarcane rake lifting section 41 is inclined upward from front to back. Preferably, the front side of the sugarcane seed conveyor belt 4 is a sugarcane rake lifting section 41, a sugarcane seed conveying section 42 and a redundant lifting section 43 from front to back. Among them, the front part of the redundant lifting section 43 is an inclined lifting section, and the rear part of the redundant lifting section 43 is a vertical lifting section, so that the sugarcane seeds can be changed from a disordered state to an ordered state during the lifting process. Each sugarcane rake baffle 44 forms an angle of 60 to 90 degrees with the outer side of the sugarcane seed conveyor belt 4, and the opening of the angle faces the running direction of the sugarcane seed conveyor belt 4. The sugarcane-pushing baffle 44 can lift the sugarcane seeds delivered by the sugarcane storage push plate 1, and during the lifting process, the sugarcane seeds will change their posture under the action of their own gravity and present a posture parallel to the sugarcane-pushing baffle 44, thereby becoming a horizontal state.

[0029] refer to Figure 1The cane sugar storage push plate 1 is installed on the front side of the cane sugar seed conveyor belt 4, and the rear opening of the cane sugar storage push plate 1 corresponds to the cane sugar rake lifting section 41, so that the cane sugar storage push plate 1 and the cane sugar rake lifting section 41 form a cane sugar storage space for storing cane sugar seeds. The structure is simple and can reduce the difficulty of structural design and manufacturing. The rear side of the bottom of the cane sugar storage push plate 1 can be flipped up and down to adjust the number of cane sugar seeds on the cane sugar rake lifting section 41. By flipping the cane sugar storage push plate 1 up and down, the shape and size of the cane sugar storage space can be changed, ensuring that the cane sugar seeds in the cane sugar storage space can be lifted by the cane sugar seed conveyor belt 4, and also ensuring that the number of cane sugar seeds lifted by the cane sugar seed conveyor belt 4 per unit time remains constant.

[0030] refer to Figure 1 The lifting mechanism 2 is used to drive the sugarcane storage push plate 1 to flip up and down, so that the sugarcane seeds in the sugarcane storage space are dumped to the side of the sugarcane seeds conveyor belt 4. Preferably, the lifting mechanism 2 includes a lifting cylinder, the upper end of which is hinged to the bottom of the sugarcane storage push plate 1. By driving the lifting cylinder to extend and retract, the sugarcane storage push plate 1 can be driven to flip up and down, and the structure is simple.

[0031] refer to Figure 1 The first distance measuring sensor 3 is installed above the cane sugar lifting section 41, and is used to detect the sugarcane seed stacking height information on the cane sugar lifting section 41, so as to obtain the number of sugarcane seeds on the cane sugar lifting section 41, and then determine the running speed of the sugarcane seed conveyor belt 4, and also determine the up and down flip angle of the cane sugar storage push plate 1, so as to ensure that the sugarcane seeds can always be smoothly lifted by the sugarcane seed conveyor belt 4. The first distance measuring sensor 3 can be a distance measuring sensor such as an ultrasonic distance measuring sensor, a laser distance measuring sensor or an infrared distance measuring sensor. Preferably, the first distance measuring sensor 3 is an ultrasonic distance measuring sensor.

[0032] refer to Figure 1 The torque sensor 5 is installed at the rotating shaft of the power motor to detect the torque information output by the power motor and feed the torque information back to the controller so that the controller can detect and judge the parameters such as the quantity of sugarcane seeds on the sugarcane seed conveyor belt 4 and the lifting status, and control the running speed of the sugarcane seed conveyor belt 4 and the up and down flipping angle of the sugarcane storage push plate 1 according to these parameters to ensure that the sugarcane seeds can be lifted efficiently. At the same time, it can also detect faults such as sugarcane seed blockage, achieve automatic stop in case of faults, and avoid equipment damage.

[0033] refer to Figure 1The sugarcane sorting pressing plate 6 is installed above the front side of the sugarcane seed conveyor belt 4 and located at the rear side of the sugarcane raking lifting section 41 in a manner that it can move up and down elastically. It can float up and down according to the change of the number of sugarcane seeds on the sugarcane seed conveyor belt 4, and is used to peel off the disordered sugarcane seeds stacked in multiple layers on the sugarcane seed conveyor belt 4, so as to achieve the purpose of initial sorting of sugarcane seeds. Among them, the sugarcane sorting pressing plate 6 is located above the sugarcane seed conveying section 42, and the sugarcane seed conveying section 42 is preferably arranged horizontally. Preferably, the sugarcane sorting pressing plate 6 is arranged upwardly inclined from back to front, and the bottom surface of the sugarcane sorting pressing plate 6 is provided with a plurality of elastic rubber plates distributed at intervals along the front-to-back direction, so as to push and peel off the disordered sugarcane seeds stacked in multiple layers. In order to facilitate the sugarcane sorting pressing plate 6 to slide up and down elastically, a sliding rod 61 is provided on the top surface of the sugarcane sorting pressing plate 6, and the sliding rod 61 is connected to the sliding sleeve 62 for sliding up and down, and the sliding sleeve 62 is fixedly arranged above the sugarcane sorting pressing plate 6, and a spring is connected between the sliding rod 61 and the sliding sleeve 62.

[0034] refer to Figure 1 The second distance sensor 7 is installed above the sugarcane sorting plate 6 to detect the distance change information of the sugarcane sorting plate 6 floating up and down, and feed back the distance change information to the controller, so that the controller can judge the quantity and orderliness of the sugarcane seeds on the sugarcane seed conveyor belt 4 at this time, and control the running speed of the sugarcane seed conveyor belt 4 and the up and down flip angle of the sugarcane storage push plate 1 according to the information such as the quantity and orderliness of the sugarcane seeds, so as to ensure that the quantity of sugarcane seeds delivered to the sugarcane seed conveyor belt 4 is kept in the best state. The second distance sensor 7 can be a distance sensor such as an ultrasonic distance sensor, a laser distance sensor or an infrared distance sensor. Preferably, the second distance sensor 7 is a laser distance sensor.

[0035] refer to Figure 1 The photoelectric sensor 8 is installed above the top of the cane seed conveyor belt 4, and the vertical distance between the photoelectric sensor 8 and the outer side of the cane seed conveyor belt 4 below it is preferably greater than the diameter of one cane seed and less than the diameter of two cane seeds, so as to detect whether there are cane seeds lifted in disorder; the cane seeds lifted horizontally will not trigger the photoelectric sensor 8, while the cane seeds lifted vertically and in disorder will be detected by the photoelectric sensor 8 due to their high height. The photoelectric sensor 8 sends a signal to the controller, and the controller controls the disordered cane removal mechanism 9 to work and remove the disordered cane seeds lifted vertically and in disorder.

[0036] refer to Figure 1The disordered sugarcane removal mechanism 9 is installed above the top of the sugarcane seed conveyor belt 4, and is used to remove the sugarcane seeds that are lifted in disorder, so as to ensure the seed supply quality of the seed supply system A. The disordered sugarcane removal mechanism 9 can be a movable removal plate 91 structure, or a rotating removal plate 91 structure. Further preferably, the disordered sugarcane removal mechanism 9 includes a cylinder 92 and a plate 91, the cylinder 92 is installed horizontally above the top of the sugarcane seed conveyor belt 4, the middle part of the plate 91 can rotate, and the upper end of the plate 91 is hinged to the push rod at the rear end of the cylinder 92. When the plate 91 is in a vertical position, the vertical distance between the lower end of the plate 91 and the outer side surface of the sugarcane seed conveyor belt 4 below it is preferably greater than the diameter of one sugarcane seed and less than the diameter of two sugarcane seeds, so that it can have a removal function. The cylinder 92 is quickly extended to drive the plate 91 to rotate, and the lower end of the plate 91 can quickly peel off the disordered sugarcane seeds lifted vertically.

[0037] refer to Figure 1 The power motor, the lifting cylinder of the lifting mechanism 2, the first distance sensor 3, the torque sensor 5, the second distance sensor 7, the photoelectric sensor 8 and the cylinder 92 of the disordered sugarcane removal mechanism 9 are all connected to the controller data. The controller is used to receive the information fed back by the first distance sensor 3, the torque sensor 5, the second distance sensor 7 and the photoelectric sensor 8, and control the work of the power motor, the lifting cylinder of the lifting mechanism 2 and the cylinder 92 of the disordered sugarcane removal mechanism 9 according to the information. The controllable lifting mechanism 2 is used to drive the sugarcane storage push plate 1 to flip upward to dump the sugarcane seeds onto the sugarcane rake lifting section 41. The first distance sensor 3 can detect the amount of sugarcane seeds on the sugarcane rake lifting section 41, and feed the information back to the controller to control the lifting height of the lifting mechanism 2 and the running speed of the sugarcane seed conveyor belt 4. The sugarcane sorting plate 6 on the sugarcane seed conveyor belt can preliminarily sort the conveyed sugarcane seeds, improve the efficiency of the sugarcane seed conveyor belt 4 in conveying sugarcane seeds, and feed back the number of sugarcane seeds on the sugarcane seed conveyor belt 4 to the controller through the second distance measuring sensor 7 to control the running speed of the sugarcane seed conveyor belt 4 and the lifting height of the lifting mechanism 2. During the lifting process, the sugarcane seeds change their posture by relying on their own gravity to achieve the effect of lateral lifting. At the same time, the torque information of the power motor is detected by the torque sensor 5, and the torque information is fed back to the controller. The controller controls the running speed of the sugarcane seed conveyor belt 4 and the lifting height of the lifting mechanism 2 according to the torque information. During the lifting process, there will be disordered situations such as sugarcane seeds being lifted vertically. In order to ensure the quality of the seed supply, a disordered sugarcane removal mechanism 9 is used to remove disordered sugarcane seeds such as vertical lifting to improve the quality of the seed supply.

[0038] refer to Figure 1 and Figure 3 , a control method for a seed supply system of a sugarcane horizontal planter, comprising the following steps:

[0039] (1) The controller controls the power motor to start, and the sugarcane seed conveyor belt 4 starts to rotate. The controller determines the state of sugarcane seed conveying and lifting on the sugarcane seed conveyor belt through the torque data fed back by the torque sensor 5. When the torque gradually increases, it means that the amount of sugarcane seeds on the conveyor belt gradually increases, and the lifting efficiency gradually decreases. At this time, the controller controls to reduce the running speed of the sugarcane seed conveyor belt 4, and controls the lifting mechanism 2 to drive the sugarcane storage push plate 1 to flip downward, reducing the amount of sugarcane seeds fed to the sugarcane seed conveyor belt 4; when the torque is reduced to the no-load torque, it means that the amount of sugarcane seeds on the sugarcane seed conveyor belt is too small, and the controller controls to increase the running speed of the sugarcane seed conveyor belt 4, and controls the lifting mechanism 2 to drive the sugarcane storage push plate 1 to flip upward, so that the sugarcane seeds are dumped onto the sugarcane rake lifting section 41, and increasing the amount of sugarcane seeds fed to the sugarcane seed conveyor belt 4; when the torque suddenly increases, it means that the sugarcane seeds are blocked or the mechanism fails. The controller immediately controls the seed supply system A to stop and sends an alarm signal, which can be sent by an alarm connected to the controller data.

[0040] (2) The controller determines the amount of sugarcane seeds piled up on the sugarcane raking and lifting section 41, i.e., the amount of sugarcane seeds piled up at the entrance of the sugarcane seed conveyor belt 4, by using the sugarcane seed pile height information fed back by the first distance measuring sensor 3. When the amount of sugarcane seeds is lower than the set value, the controller controls the lifting mechanism 2 to drive the sugarcane storage push plate 1 to flip upwards and dump the sugarcane seeds onto the sugarcane raking and lifting section 41; when the amount of sugarcane seeds reaches the set value, the controller controls the lifting mechanism 2 to stop lifting or stopping descending; when the amount of sugarcane seeds exceeds the set value, the controller controls the lifting mechanism 2 to drive the sugarcane storage push plate 1 to flip downwards. At the same time, the controller adjusts the speed of the power motor according to the sugarcane seed pile height information fed back by the first distance measuring sensor 3. When the sugarcane seed pile height exceeds the set value, the controller controls to reduce the speed of the power motor, thereby reducing the running speed of the sugarcane seed conveyor belt 4 to avoid mechanism failure caused by too much sugarcane seeds lifted per unit time; when the height of the sugarcane seed pile is too low, the speed of the power motor is appropriately increased, thereby increasing the running speed of the sugarcane seed conveyor belt 4; that is, the speed of the power motor is inversely proportional to the sugarcane seed pile height, and the proportional value is K, so as to always keep the stability and efficiency of the seed supply quantity of the sugarcane seed conveyor belt.

[0041] (3) When the sugarcane seeds to be lifted pass under the sugarcane sorting plate 6, the distance of the sugarcane sorting plate 6 floating up and down will change. If too many sugarcane seeds are lifted at a certain moment, the height of the sugarcane sorting plate 6 will be higher, and the sugarcane sorting effect of the sugarcane sorting plate will also be worse. The controller determines the amount of sugarcane seeds piled on the sugarcane seed conveyor belt 4 under the sugarcane sorting plate 6 through the distance change information fed back by the second distance measuring sensor 7, thereby controlling the running speed of the sugarcane seed conveyor belt 4 and the lifting height of the lifting mechanism 2 to maintain the stability of the amount of sugarcane seeds on the sugarcane seed conveyor belt. When the height of the sugarcane sorting plate 6 is lifted exceeds the set value, the controller controls the power motor to reduce the movement speed of the sugarcane seed conveyor belt 4, and controls the lifting mechanism 2 to drive the sugarcane storage push plate 1 to flip downward, reducing the amount of sugarcane seeds delivered by the sugarcane storage push plate 1 to the sugarcane raking lifting section 41, so that the excess sugarcane seeds on the sugarcane seed conveyor belt 4 are gradually lifted in an orderly manner, and then gradually resume normal operation.

[0042] (4) The controller uses the information fed back by the photoelectric sensor 8 to determine whether there are any disorderly lifted sugarcane seeds on the sugarcane seed conveyor belt 4. When the photoelectric sensor 8 detects the presence of disorderly sugarcane seeds, the controller controls the disorderly sugarcane removing mechanism 9 to operate and remove the disorderly sugarcane seeds to ensure the seed supply quality of the seed supply system A.

[0043] refer to Figure 2 When the seed supply system A of the present invention is in use, the seed supply system A is located on the upper part of the row sowing system B, and the operation state of the seed supply system A is adjusted according to the number of sugarcane seeds required by the row sowing system B. The orderly sugarcane seeds required by the row sowing system B for row sowing operations need to be provided by the seed supply system A. The function of the seed supply system A of the sugarcane horizontal planter is to transform the disordered sugarcane seeds carried into an orderly state after the processes of sugarcane sorting, orderly lifting, and removing disordered sugarcane, and then supply the row sowing system B. Moreover, under the operation states of the row sowing system B at different speeds, the seed supply system A can change the seed supply efficiency to cooperate with the work of the row sowing system B, and has strong practicality.

The controller controls the running speed of the sugarcane seed conveyor belt to increase, and controls the lifting mechanism to drive the sugarcane storage push plate to flip upward to dump the sugarcane seeds onto the sugarcane rake lifting section. When the torque suddenly increases, it means that the sugarcane seeds are blocked or the mechanism fails. The controller immediately controls the seed supply system to shut down and sends an alarm signal. (2) The controller determines the amount of sugarcane seeds piled up on the sugarcane rake lifting section by using the sugarcane seed accumulation height information fed back by the first distance measuring sensor; when the amount of sugarcane seeds is lower than the set value, the controller controls the lifting mechanism to drive the sugarcane storage push plate to flip upwards and dump the sugarcane seeds onto the sugarcane rake lifting section; when the amount of sugarcane seeds reaches the set value, the controller controls the lifting mechanism to stop lifting or stopping descending; when the amount of sugarcane seeds exceeds the set value, the controller controls the lifting mechanism to drive the sugarcane storage push plate to flip downwards; at the same time, the controller adjusts the speed of the power motor according to the sugarcane seed accumulation height information fed back by the first distance measuring sensor, thereby adjusting the running speed of the sugarcane seed conveyor belt, thereby maintaining the stability and efficiency of the supply of seeds on the sugarcane seed conveyor belt; (3) When too much sugarcane seeds are piled up on the sugarcane seed conveyor belt, the height of the sugarcane sorting plate will be raised higher. The controller determines the amount of sugarcane seeds piled up on the sugarcane seed conveyor belt through the distance change information fed back by the second distance measuring sensor, thereby controlling the running speed of the sugarcane seed conveyor belt and the lifting height of the lifting mechanism to maintain the stability of the amount of sugarcane seeds on the sugarcane seed conveyor belt; (4) During the operation of the sugarcane seed conveyor belt, the controller uses the information fed back by the photoelectric sensor to determine whether there are sugarcane seeds that are lifted out of order on the sugarcane seed conveyor belt. When the photoelectric sensor detects the presence of out-of-order sugarcane seeds, the controller controls the out-of-order sugarcane removal mechanism to remove the out-of-order sugarcane seeds to ensure the seed supply quality of the seed supply system.
