Description

Technical Field

[0001] The utility model relates to an agricultural mechanical device, and more specifically to a sugarcane seed cutting device. Background Art

[0002] In most areas of our country, manual methods are still used to plant sugarcane. Before planting sugarcane, the sugarcane stalks with buds need to be cut into sugarcane seed segments first, and one or more buds are reserved on each sugarcane seed segment. In addition, to ensure the quality of the sugarcane seeds, it is necessary to check the buds on each sugarcane seed segment to ensure that the buds are normal.

[0003] Most of the existing sugarcane seed cutting devices are driven by a motor to make the cutter reciprocate. After the cutter is lifted, the sugarcane stalk is placed under the cutter, and the sugarcane stalk is cut when the cutter falls. Due to the differences in sugarcane stalks, the action of placing the sugarcane stalk under the cutter is usually manual, and usually, the quality of the buds on the sugarcane stalk is checked manually. For the sugarcane stalk segments with unqualified buds, they need to be cut and discarded. Due to the differences in the proficiency of workers and the different lengths of time for checking buds, the time for workers to operate the sugarcane stalk cutting varies. However, the sugarcane seed cutting device is driven by a machine, and the cutter reciprocates at a fixed cycle. Therefore, when the operator uses this sugarcane seed cutting device to cut sugarcane seed segments, the operator has to follow the rhythm of the machine and be in a highly concentrated and tense state, and the operator is prone to fatigue. In addition, the rhythm of people cannot always be synchronized with the machine, thus affecting the operation efficiency. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is the problem of cutting sugarcane seed segments, and a sugarcane seed cutting device is provided to improve the working efficiency of cutting sugarcane seed segments.

[0005] The technical solution for the utility model to achieve its purpose is: a sugarcane seed cutting device, which includes: a frame, a motor for driving a disc cutter, a swing frame, a cylinder, and a control device;

[0006] The frame is provided with a sugarcane stalk placing rack for placing sugarcane stalks to be cut;

[0007] The motor is fixedly installed on the swing frame, and the swing frame is rotatably installed on the frame through a pin shaft;

[0008] Both ends of the cylinder are respectively connected to the frame and the swing frame, and the cylinder is used to push the swing frame to make the disc cutter enter and exit the sugarcane seed cutting area of the sugarcane stalk placing rack;

[0009] The control device includes an electromagnetic air valve connected to a pressure air source and used to control the telescopic movement of a cylinder, an electronic control unit electrically connected to the electromagnetic air valve, and a first detection unit electrically connected to the electronic control unit and used to detect whether there is a cane placed on the cane shelf; the electronic control unit controls the electromagnetic air valve to change its direction based on the detection signal of the first detection unit.

[0010] In the present utility model, when the first detection unit detects that there is a cane placed on the cane shelf, the electromagnetic air valve controls the cylinder to extend, pushing the swing frame to swing and moving the disc cutter towards the cane on the cane shelf to cut the cane. After the cane leaves the cane shelf, the detection signal of the first detection unit changes, and the electronic control unit controls the electromagnetic air valve to retract the cylinder, and the disc cutter leaves the cane shelf to prepare for the next cane cutting. The first detection unit can be an inductive switch, such as an infrared inductive switch, or a contact push switch.

[0011] In the cane cutting device of the present utility model, the cane shelf is composed of two support plates arranged side by side on the frame. Both of the two support plates are provided with cane placement grooves with openings facing upwards, and the cane cutting area of the cane shelf is located between the two support plates. The cane placement grooves are provided to prevent the position of the cane from moving when the disc cutter rotates to cut the cane.

[0012] In the cane cutting device of the present utility model, a cutter protection plate for protecting the disc cutter is provided above the cane cutting area of the cane shelf on the frame. When the disc cutter rotates to cut the cane, the disc cutter extends outside the frame, which is somewhat dangerous. The cutter protection plate isolates the disc cutter to prevent people or objects from accidentally contacting the rotating disc cutter and causing damage to people or objects.

[0013] In the cane cutting device of the present utility model, a cane segment guiding groove for guiding the cane segments to slide down is provided at the lower part outside one of the two support plates. After the cane is cut into cane segments, the cane segments automatically fall into the cane segment guiding groove and are guided by it to slide towards a frame or box for containing the cane segments.

[0014] In the cane cutting device of the present utility model, the distance between the disc cutter and the support plate adjacent to the cane segment guiding groove is less than the distance between the disc cutter and the other support plate. This structure facilitates the automatic dropping of the cane segments outside the cane shelf under their own gravity after the cane is cut.

[0015] In the cane cutting device of the present utility model, the frame includes a skeleton and a protection plate arranged on the skeleton to form a closed or semi - closed box body. Semi - closed means that one or more walls of the box body do not have a protection plate because there is no need for protection, and protection plates are provided on other walls. The protection plate is provided to protect the devices inside the frame box body.

[0016] In the sugarcane seed cutting device of the present utility model, the control device further includes a first counter electrically connected to the electronic control unit, and the first counter counts based on the number of changes in the detection signal of the first detection unit. When a sugarcane stalk is placed on and taken out from the sugarcane stalk rest rack once, the air cylinder extends and retracts once, and the disc cutter performs a cutting action on the sugarcane stalk once, and the number of changes in the detection signal of the first detection unit increases by one. The cutting times of the sugarcane seed cutting device can be counted through the first counter, thereby counting its workload.

[0017] In the sugarcane seed cutting device of the present utility model, the control device further includes a second counter electrically connected to the electronic control unit and a second detection unit electrically connected to the electronic control unit for detecting the dropping of sugarcane seed segments beside the sugarcane stalk rest rack, and the second counter counts based on the number of changes in the detection signal of the second detection unit. When each sugarcane seed segment drops, the detection signal of the second detection unit changes once, and the number of sugarcane seed segments can be counted through the second counter.

[0018] In the sugarcane seed cutting device of the present utility model, a buffer pad is provided between the frame and the swing frame, and the swing frame abuts against the frame through the corresponding buffer pad when the air cylinder is at the extended extreme position and the retracted extreme position.

[0019] In the sugarcane seed cutting device of the present utility model, the control device includes a main air valve with an air inlet communicating with the air source, an air-water separator with an air inlet communicating with the air outlet of the main air valve, and a pneumatic pressure regulating valve. The air outlet of the air-water separator communicates with the air inlet of the solenoid air valve. The two working air ports of the solenoid air valve are respectively communicated with the large chamber and the small chamber of the air cylinder through the pneumatic pressure regulating valve. By adjusting the air pressure, the telescopic speed of the air cylinder can be controlled.

[0020] Compared with the prior art, in the present utility model, by using the detection unit to detect whether there is a sugarcane stalk placed on the sugarcane stalk rest rack, and only pushing out the disc cutter to cut the sugarcane stalk when there is a sugarcane stalk placed, the actions of the worker and the machine are synchronized when the worker operates the device to cut the sugarcane seeds, and the human action is the dominant one, improving the efficiency and reducing the labor intensity.

[0030] Sugarcane rod 90, sugarcane seed segment 91. Specific implementation mode

[0031] The following describes the specific implementation mode with reference to the accompanying drawings.

[0032] As Figure 1 shown, in this embodiment, the sugarcane seed cutting device includes: a frame 10, a motor 31 that drives the disc cutter 32 to rotate, a swing frame 30, a cylinder 33, and a control device.

[0033] A sugarcane rod rest 20 for placing the sugarcane rod 90 to be cut is provided on the frame 10. The motor 31 is fixedly installed on the swing frame 30, and the swing frame 30 is rotatably installed on the frame 10 through a pin shaft. Both ends of the cylinder 33 are respectively connected to the frame 10 and the swing frame 30, and the cylinder 33 is used to push the swing frame 30 to make the disc cutter 32 enter and exit the sugarcane seed cutting area of the sugarcane rod rest 20.

[0034] The control device includes a solenoid air valve 44 connected to a pressure air source (not shown in the figure) and used to control the expansion and contraction of the cylinder 33, an electric control unit (not shown in the figure) electrically connected to the solenoid air valve 44, and a first detection unit electrically connected to the electric control unit and used to detect whether there is a sugarcane rod 90 placed on the sugarcane rod rest 20.

[0035] The sugarcane is a rod-shaped object. When it is placed on the sugarcane rack 20, the first detection unit 47 is triggered by the sugarcane and sends an electrical signal to the control unit. The electronic control unit controls the electromagnetic air valve 44 to extend the cylinder 33, pushing the swing frame 30 to swing forward, causing the disk cutter 32 to move towards the sugarcane 90 on the sugarcane rack 20. The rotating disk cutter 32 cuts the sugarcane 90. After the sugarcane 90 leaves the sugarcane rack 20, the detection signal of the first detection unit 20 changes. The electronic control unit controls the electromagnetic air valve 44 to retract the cylinder 33, and the disk cutter 32 leaves the sugarcane rack 20, preparing for the next cutting of the sugarcane 90. The first detection unit 47 can be an inductive switch, such as an infrared inductive switch. The first detection unit 47 can also be a contact pressure switch. When the sugarcane 90 is placed on the sugarcane rack 20, the sugarcane 90 presses the pressure switch to trigger it, making the circuit that generates the electrical signal conductive. After the sugarcane 90 leaves, the pressure switch is released, and the circuit that generates the electrical signal is disconnected.

[0036] As Figure 1 shown, the frame 10 includes a skeleton and a protective plate arranged on the skeleton to form a closed or semi-closed box body. When necessary, legs 12 can also be arranged at the lower part.

[0037] The semi-closed box body means that one or more wall surfaces of the box body do not have a protective plate and present an open state, and protective plates are arranged on other wall surfaces. The protective plate is set to protect the devices in the frame box body. The motor 31, the swing frame 30, the cylinder 33, and the disk cutter 32 are arranged in the box body. The swing frame 30 is plate-shaped, and the motor 31 is fixed on the swing frame 30. The lower end of the swing frame 30 is installed on the frame 10 through a pin shaft. The front and rear ends of the cylinder 33 are correspondingly connected to the swing frame 30 and the frame 10. When the cylinder 33 expands and contracts, it can push the swing frame 30 to swing back and forth around the lower pin shaft. The disk cutter 32 is fixed on the rotating shaft of the motor 31 and is driven by the motor 31 to rotate.

[0038] As Figure 4 shown, a front protective plate 16 is provided on the front side of the frame 10, and a cutter entrance and exit for the disk cutter 32 to enter and exit is provided on the front protective plate 16. The sugarcane rack 20 is fixed on the front side of the front protective plate of the frame.

[0039] A buffer pad is provided between the frame 10 and the swing frame 30. When the cylinder 33 is at the extended extreme limit position and the retracted extreme limit position, the swing frame 30 abuts against the frame 10 through the corresponding buffer pads. As Figure 4 shown, a first shock-absorbing pad 15 is fixedly installed on the rear protective plate of the frame 10. When the cylinder 33 retracts to the extreme limit position, the rear end of the swing frame 30 collides with and is buffered by the first buffer pad 15, reducing the impact when the cylinder 33 retracts to the end of the stroke. As Figure 2As shown in the figure, a second shock pad 34 is fixed to the front part of the swing frame 30. When the cylinder 33 extends to its extreme limit position, the second buffer pad 34 at the front end of the swing frame 30 collides with the front protection plate 16 of the frame 10 for buffering, reducing the impact when the cylinder 33 extends to the end of its stroke.

[0040] As Figure 3 As shown in the figure, the cane rod shelving 20 is composed of a first support plate 21 and a second support plate 22, and the first support plate 21 and the second support plate 22 are arranged vertically in parallel. At the upper parts of the first support plate 21 and the second support plate 22, cane rod placement grooves with upward openings are provided, and the cane rods 90 can be placed in the cane rod placement grooves. The cane seed cutting area of the cane rod shelving 20 is located between the first support plate 21 and the second support plate 22. When the disc cutter 32 extends out from the cutter entrance and exit, the disc cutter 32 obliquely moves downward into the cane seed cutting area between the first support plate 21 and the second support plate 33, and cuts the cane rod 90 placed in the cane rod placement groove at this position. The opening of the cane rod placement groove faces upward, and the disc cutter 32 moves downward for cutting. When cutting the cane rod 90, the cane rod 90 can be restricted in the cane rod placement groove, preventing the cane rod from moving in position.

[0041] Above the cane seed cutting area of the cane rod shelving 20 on the frame 10, a cutter protection plate 14 for protecting the disc cutter 32 is provided. When the disc cutter 32 rotates to cut the cane rod, the disc cutter 32 extends out of the frame 10, which has a certain degree of danger. The cutter protection plate 14 isolates the disc cutter 32, preventing people or objects from accidentally coming into contact with the rotating disc cutter 32 and causing damage to people or objects.

[0042] At the lower part outside the first support plate 21, a cane seed segment guiding groove 13 for guiding the sliding of the cane seed segments 91 is provided. After the cane rod 90 is cut into cane seed segments 91, the cane seed segments 91 automatically fall into the cane seed segment guiding groove 13 and are guided by it to slide towards the frame or box for holding the cane seed segments. Optionally, the distance between the disc cutter 32 and the first support plate 21 is less than the distance between the disc cutter 32 and the second support plate 22. After the cane rod is cut, the cane seed segments 91 are only supported by the first support plate 21, and the center of gravity of the cane seed segments 91 is located outside the first support plate 21. Since the support position is not at the center of gravity of the cane seed segments 91, the cane seed segments 91 automatically fall outside the first support plate 21 under their own gravity and enter the cane seed segment guiding groove 13.

[0043] As Figure 2As shown in the figure, the control device further includes a main air valve 42 with an air inlet communicating with an air source (not shown in the figure), a water-air separator 43 with an air inlet communicating with the outlet of the main air valve 42, and a pneumatic pressure regulating valve 45. The outlet of the water-air separator 43 communicates with the inlet of the solenoid air valve 44. The two working air ports of the solenoid air valve 44 respectively communicate with the large chamber and the small chamber of the cylinder 33 through the pneumatic pressure regulating valve 45. The main air valve 42 is a switch solenoid valve, which is conductive when energized and cut off when de-energized. Compressed air enters the water-air separator 43 through the main air valve 42 to remove the water vapor in the compressed air. The solenoid air valve 44 is a reversing valve, which can control the flow direction of the compressed air to the large chamber or the small chamber of the cylinder 33 through commutation, so that the cylinder 33 extends or contracts. The pneumatic pressure regulating valve 45 is used to adjust the pressure of the compressed air entering the cylinder 33. By adjusting the air pressure, the telescopic speed of the cylinder 33 can be controlled. As Figure 2 shown, the main air valve 42, the water-air separator 43, the pneumatic pressure regulating valve 45, and the solenoid air valve 44 are arranged at the rear side of the frame 10.

[0044] As Figure 2 Figure 3 shown, an electric control box 40 is provided on the right side of the frame 10, and the electric control unit is installed in the electric control box 40. The first detection unit 47 installed on the frame 10 is electrically connected to the electric control unit, and the electric control unit controls the telescopic movement of the cylinder by controlling the solenoid air valve based on the electrical signal of the first detection unit 47.

[0045] The control device further includes a first counter 48 electrically connected to the electric control unit. The first counter 48 counts based on the number of changes in the detection signal of the first detection unit 47. When the sugarcane stalk 90 is placed and taken out on the sugarcane stalk rack 20 once, the cylinder 33 extends and contracts once, and the disk cutter 32 performs a cutting action on the sugarcane stalk 90, and the detection signal of the first detection unit 47 changes once. The cutting times of the sugarcane seed cutting device can be counted through the first counter 48, so as to count its workload.

[0046] The control device further includes a second counter 49 electrically connected to the electric control unit and a second detection unit 46 electrically connected to the electric control unit for detecting the dropping of sugarcane seed segments beside the sugarcane stalk rack. The second counter 49 counts based on the number of changes in the detection signal of the second detection unit 46. When each sugarcane seed segment 91 drops, the detection signal of the second detection unit 46 changes once. The number of sugarcane seed segments 91 can be counted through the second counter 49.

[0047] In this embodiment, when the worker operating the sugarcane seed cutting device performs the sugarcane seed cutting operation, after detecting the quality of the buds on the sugarcane stalk, the worker places the sugarcane stalk 90 at an appropriate position on the sugarcane stalk rack, as Figure 3As shown, the sugarcane stalk 91 on the sugarcane stalk rack 20 triggers the first detection unit 47. The control device controls the cylinder 33 to extend, and the disk cutter 32 swings forward with the swing frame 30 to cut off the sugarcane stalk 90. When the sugarcane stalk 90 triggers the first detection unit 47, the count of the first counter 48 is incremented by one.

[0048] If the buds on the cut sugarcane segment meet the planting requirements, then this sugarcane segment is a sugarcane seed segment 91. After being cut off by the disk cutter, it automatically falls into the sugarcane seed segment guide groove 13 and slides into the sugarcane seed segment storage box. During the process of the sugarcane seed segment 91 falling, it triggers the second detection unit 46, and the count of the second counter 49 is incremented by one. If the buds on the cut sugarcane segment do not meet the planting requirements, then this sugarcane segment is a waste sugarcane seed segment. When the worker holds this sugarcane segment and places it separately when the disk cutter cuts off this sugarcane segment, this process does not trigger the second detection unit 46, and the count of the second counter 49 is not incremented. The first counter 48 is used to count the workload of the operator, that is, the number of times of sugarcane stalk cutting. The second counter 49 is used to count the number of sugarcane seed segments 91. The second detection unit 46 can be an inductive device, such as an infrared proximity switch.

[0049] On the electric control box 40, there is also a main switch 50 and a motor switch 51. The main switch 50 is used to power on or off the control device of the sugarcane seed cutting device. When the main switch 50 is turned off, the control device is powered off. The motor switch 51 is used to start or stop the motor.

[0050] In this embodiment, the cutting action of the disk cutter 32 on the sugarcane stalk 90 is triggered by the operator placing the sugarcane stalk 90 on the sugarcane stalk rack 20 to trigger the first detection unit 47. After the sugarcane stalk on the sugarcane stalk rack 20 is removed, the disk cutter automatically returns to its original position, achieving synchronization between the machine and the operator. The worker performing the sugarcane seed cutting can master the rhythm of the sugarcane seed cutting operation, without being in a state of highly concentrated attention, reducing the work intensity and improving the operation efficiency.
