Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a device and method for automatically collecting and stacking plug trays. Background Art

[0002] Vegetable production has become the second largest crop in my country's agricultural sector, second only to grain. my country is the world's largest producer and consumer of vegetables. With rising living standards, demand for vegetables is growing, leading to an increase in vegetable planting area and yield. Consequently, vegetable transplanting machinery has also developed accordingly. Mechanized and automated seedling transplanting technology for tray seedlings has been widely used in the production of crops such as tobacco, rapeseed, cotton, and vegetables.

[0003] With the development of modern agricultural technology, tray transplanters have gradually become more sophisticated in terms of tray transportation, seedling removal, and planting. However, existing transplanters generally lack empty tray recovery devices. After transplanting, the empty trays fall freely and need to be picked up manually. This leads to the problem of falling trays and crushing seedlings, and the later collection of empty trays is time-consuming and labor-intensive. Failure to collect the empty trays in a timely manner also has environmental problems. In addition, existing empty tray recovery devices are often too large, take up space, and the empty tray transportation mechanism is complex, and it is prone to tray blockage.

[0004] The present invention is achieved through the following technical solutions:

[0005] A device for automatically collecting and stacking a cell tray, comprising a control system and a hole insertion mechanism, a lifting device, a lateral pushing device, and a stacking locking mechanism located in a cell tray recovery box;

[0006] The initial position of the hole insertion mechanism is located at the upper part of the hole tray recovery box. The hole insertion mechanism includes an insertion rod mechanism and a driving mechanism I that drives the insertion rod mechanism to rotate. The insertion rod mechanism acts on a plurality of water leakage holes at the bottom of the hole tray transported by the hole tray conveying device. The two sides of the hole insertion mechanism are fixedly connected to the lifting devices provided on the left and right sides of the hole tray recovery box, and the hole insertion mechanism is driven to rise or fall by the lifting device.

[0007] The horizontal pushing device is installed at the bottom of the hole tray recovery box, which includes a rake-shaped push rod driven by the driving mechanism II to move and act on a plurality of rows of grooves at the bottom of the hole tray. An empty hole tray parallel to the vertically arranged rake-shaped push rod is also provided inside the hole tray recovery box. The empty hole tray is in contact with a spring push plate, and a push plate spring is provided between the spring push plate and the inner wall of the hole tray recovery box. When the hole tray contacts the empty hole tray under the push of the rake-shaped push rod, the hole tray is clamped by the stacking locking mechanism installed on both sides of the hole tray recovery box.

[0008] A sensor A for detecting the hole tray conveying position and the leakage hole signal at the bottom of the hole tray is installed on the upper part of the hole tray recovery box, a sensor B for detecting the hole tray arrival signal is installed at the bottom of the hole tray recovery box, and a sensor C for detecting the position of the spring push plate is installed in the middle of the hole tray recovery box. The control system is electrically connected to sensor A, sensor B, sensor C, the hole insertion mechanism, the lifting device, and the lateral pushing device respectively.

[0009] Furthermore, the plug-in rod mechanism includes a plurality of plug-in push rods acting on the first row of water leakage holes at the bottom of the plug tray, the rod portions of the plurality of plug-in push rods pass through a horizontally arranged rotating body, the plug-in push rods are driven to move as a whole by a cylinder arranged on the rotating body, and the left and right sides of the rotating body are respectively mounted on two fixed blocks through a rotating shaft;

[0010] The driving mechanism I includes a rotating motor installed on one of the fixed blocks, which drives the rotating body and the jack push rod to rotate through an engaged gear mechanism, and the two fixed blocks are fixedly connected to the lifting devices arranged on the left and right sides of the hole tray recovery box.

[0011] Furthermore, the diameter of the jack push rod is smaller than the diameter of the water leakage hole in the hole tray.

[0012] Furthermore, the gear mechanism includes a driving gear matched with the rotating shaft and a driven gear matched with the rotating body.

[0013] Furthermore, the lifting device includes guide rails installed on both sides of the hole tray recovery box, and the hole insertion mechanism is driven by a motor to rise or fall.

[0014] Furthermore, the stacking locking mechanism is installed in the installation frame on both sides of the middle part of the hole tray recovery box, which includes a rotating shaft, a movable baffle, a telescopic spring, and a fixed baffle. The movable baffle is movably connected to the installation frame through the rotating shaft, one end of the fixed baffle is fixedly connected to the installation frame, and the other end of the fixed baffle is suspended, and the telescopic spring is located between the movable baffle and the fixed baffle.

[0015] Furthermore, the telescopic spring is made of low manganese spring steel, and the push plate spring is made of chrome vanadium steel.

[0016] Furthermore, the rake-shaped push rod includes several vertically arranged push rods, which are supported by support rods arranged horizontally at the bottom. The driving mechanism II is a guide rail motor. The bottom of the support rod is slidably connected to the guide rail through a slider. The guide rail motor drives the slider to slide, thereby driving the rake-shaped push rod to move.

[0017] Furthermore, a guide baffle for guiding the cell tray to move downward is vertically provided on the upper part of the cell tray recovery box and on one side of the hole insertion mechanism.

[0018] The present invention also provides a method for automatically recovering and stacking plug trays, the specific method being:

[0019] S1. The plug tray is transported by a horizontally arranged plug tray conveying device. The plug tray is conveyed downward at the end of the conveying device under the limit of the slots on both sides;

[0020] S2. The hole tray moves downward along the guide baffle under the guidance of the guide baffle. After the sensor A detects the first row of water leakage holes in the hole tray, it immediately transmits the signal to the control system, and the control system transmits the signal to the hole insertion mechanism;

[0021] S3. The rotary motor of the hole insertion mechanism drives the insertion rod mechanism to rotate through the gear mechanism, adjusts the posture of the jack push rod, and at the same time drives the cylinder to drive the jack push rod to move a certain distance and insert it into the first row of water leakage holes in the plug tray. After completing the above action, the control system transmits a signal to the lifting device to pull the plug tray down;

[0022] S4. After the sensor B at the bottom of the tray recovery box detects the tray arrival signal, the arrival signal is transmitted to the control system, which then transmits the signal to the lateral pushing device, causing the rake-shaped push rod to move laterally against the rows of grooves at the bottom of the tray;

[0023] S5. After the rake-shaped push rod moves a certain distance, the hole tray falls off the jack push rod, the lifting device drives the hole insertion mechanism to rise, and the cylinder drives the jack push rod back to the initial position to wait for the next command;

[0024] S6, the rake-shaped push rod continues to push the cell tray to move horizontally. After it moves to the position of the stacking locking mechanism, the movable baffle is closed under the pressure of the cell tray. At this time, the telescopic spring is in a compressed state. After the cell tray passes the stacking locking mechanism, the movable baffle is opened under the force of the telescopic spring.

[0025] S7. After the hole tray passes through the stacking locking mechanism, it contacts the empty hole tray on the spring push plate under the push of the rake-shaped push rod, completing the stacking of the hole tray and the empty hole tray. At the same time, the spring push plate compresses the push plate spring. After the sensor C detects the compression signal, it transmits the signal to the control system. The control system transmits the signal to the lateral pushing device to control the rake-shaped push rod to return to the initial position.

[0026] S8. The spring push plate moves under the action of the push plate spring. When it moves to the open movable baffle, the movable baffle presses against the edge groove of the hole tray to complete the locking. This reciprocating operation is repeated until the hole tray compresses the spring push plate to the set position. The sensor C transmits a signal to the control system, and then reminds the control system to remove the stacked hole trays by opening and closing the door.

[0027] The beneficial effects of the present invention are:

[0028] 1. The present invention drives the hole insertion mechanism to rotate through a gear mechanism and a cylinder, which can adjust the direction of the rod insertion device and the angle of the seedling tray delivery, and can adapt to different seedling tray delivery devices and transplanting work occasions;

[0029] 2. The present invention realizes the integration of empty disk recovery and stacking, abandons the traditional conveyor belt structure, adopts a transverse pushing device for traction, greatly reduces the volume occupied by the empty disk recovery device, and does not cause disk blockage, making the empty disk recovery more orderly;

[0030] 3. The stack locking mechanism of the present invention adopts a simple spring baffle structure for locking, which reduces the complex control process and makes it easier to achieve the stack locking function;

[0031] 4. The various components of the present invention are driven by motors and cylinders. The overall device not only facilitates the control system to effectively and stably perform mechanical operations, but also has a compact structure, simple operation and easy maintenance.

The plug tray recycling box 15 is the frame of the whole automatic plug tray collecting and stacking device, serving as the frame carrier of the structure and device.

[0041] The pair of hole inserting mechanism 3 is initially located at one end of the upper part of the plug tray recycling box 15. The pair of hole inserting mechanism 3 comprises a plug rod mechanism and a driving mechanism I for rotating the plug rod mechanism. The plug rod mechanism acts on a plurality of water leakage holes in the first row at the bottom of the plug tray 1 conveyed by the plug tray conveying device 2. The pair of hole inserting mechanism 3 is fixedly connected with the lifting device 8 arranged on the left and right sides of the plug tray recycling box 15, and is lifted or lowered by the lifting device 8.

[0042] Preferably, the plug rod mechanism comprises a plurality of plug hole push rods 306 acting on the water leakage holes in the first row at the bottom of the plug tray. The rod portions of the plurality of plug hole push rods 306 penetrate through a horizontally arranged rotating body 307. The diameters of the rod portions of the plug hole push rods 306 are all smaller than the diameter of the water leakage holes of the plug tray, so as to facilitate the insertion into the water leakage holes of the plug tray and the completion of the traction. The plug hole push rods 306 are driven by the air cylinder 305 arranged on the rotating body 307 to move as a whole. The rotating body 307 is respectively installed on two fixed blocks 302 through rotating shafts 308 arranged on the left and right sides.

[0043] The driving mechanism I comprises a rotating motor 301 installed on one of the fixed blocks. The rotating motor 301 drives the rotating body 307 and the plug hole push rods 306 to rotate through the meshing gear mechanism. The two fixed blocks 302 are fixedly connected with the lifting device 8 arranged on the left and right sides of the plug tray recycling box 15, so as to drive the whole pair of hole inserting mechanism to lift or lower. The gear mechanism comprises a driving gear 303 matched with the rotating shaft 308 and a driven gear 304 matched with the rotating body 307.

[0044] The lifting device 8 comprises guide rails installed on the left and right sides of the plug tray recycling box 15.

The empty hole tray 14 is in contact with the spring push plate 5, and a push plate spring 12 is provided between the spring push plate 5 and the inner wall of the hole tray recovery box 15. When the hole tray 1 contacts the empty hole tray 14 under the push of the rake-shaped push rod, the hole tray 1 is clamped by the stacking locking mechanism 6 installed on both sides of the hole tray recovery box 15;

[0046] The rake-shaped push rod 901 includes several vertically arranged push rods, and the several push rods are supported by support rods arranged horizontally at the bottom. The driving mechanism II is a guide rail motor 904, and the bottom of the support rod is slidably connected to the guide rail through a slider 902. The guide rail motor 904 drives the guide rail screw 903 to make the slider slide, thereby driving the rake-shaped push rod 901 to move. The guide rail installation position is lower than the bottom surface of the hole tray recovery box 15 to prevent the horizontal pushing device from interfering with the hole tray. The rake-shaped push rod 901 in the horizontal pushing device 9 and the socket push rod 301 in the hole insertion mechanism 3 act on the groove at the bottom of the hole tray and the water leakage hole respectively, and the two do not interfere with each other during the action process. The groove corresponding to the rake-shaped push rod 901 is the gap between the bottoms of several rows of hole tray holes,

The control system 4 can be located outside the hole tray recovery box 15; the control system 4 is electrically connected to the sensor A10, sensor B, sensor C13, the hole insertion mechanism 3, the lifting device 8, and the horizontal pushing device 9 respectively.

[0048] Sensor A10 transmits the corresponding signal to the control system 4, and the control system 4 transmits the hole position signal of the first row of the hole tray to the hole insertion mechanism 3, and the hole insertion mechanism drives the motor to rotate through the gear drive mechanism to adjust the posture of the hole device, and then the cylinder of the drive hole device drives the hole mechanism to move a certain distance and insert it into the first row of holes in the hole tray; after completing the action, sensor A will complete the signal and transmit it to the control system, and the control system will transmit the in-position signal to the lifting device 8 to control its rise and fall; the sensor B is installed at the bottom of the hole tray recovery box to detect the in-position signal of the empty hole tray, and transmit the in-position signal to the control system 4, and the control system 4 then transmits the signal to the lateral pushing device 9 to control the lateral movement of the lateral pushing device 9; after the hole trays are stacked to compress the spring baffle to the limit position, the sensor C transmits the signal to the control system.

[0049] Furthermore, the stacking locking mechanism 6 is installed in the installation frame on both sides of the middle part of the hole tray recovery box 15, which includes a rotating shaft 601, a movable baffle 602, a telescopic spring 603, and a fixed baffle 604. The movable baffle 602 is movably connected to the installation frame through the rotating shaft 601, one end of the fixed baffle 604 is fixedly connected to the installation frame, and the other end of the fixed baffle 604 is suspended. The telescopic spring 603 is located between the movable baffle 602 and the fixed baffle 604, and the telescopic spring 603 controls the switch of the movable baffle 602.

[0050] Furthermore, the telescopic spring 603 is made of low manganese spring steel, which has good hardenability and high strength and is suitable for springs of smaller sizes. The push plate spring 12 is made of chrome vanadium steel, which has good fatigue resistance and impact resistance.

[0054] S2, the hole tray 1 moves downward along the guide baffle 11. After the sensor A10 detects the first row of water leakage holes in the hole tray 11, it immediately transmits the signal to the control system 4, and the control system 4 transmits the signal to the hole insertion mechanism 3;

[0055] S3, the rotating motor 301 of the hole insertion mechanism 3 drives the insertion rod mechanism to rotate through the gear mechanism, adjusts the posture of the hole insertion push rod 306, and at the same time drives the cylinder 305 to drive the hole insertion push rod 306 to move a certain distance and insert it into the first row of water leakage holes in the hole tray 1.

[0057] S5, after the rake-shaped push rod 901 moves a distance, the hole tray 1 falls off the jack push rod 306, the lifting device 8 drives the hole insertion mechanism 3 to rise, and the cylinder 305 drives the jack push rod 306 back to the initial position to wait for the next command;

[0058] S6, the rake-shaped push rod 901 continues to push the cell tray 1 to move horizontally. After it moves to the position of the stacking locking mechanism 6, the movable baffle 602 is closed under the pressure of the cell tray 1. At this time, the telescopic spring 603 is in a compressed state; after the cell tray 1 passes through the stacking locking mechanism 6, the movable baffle 602 is opened under the force of the telescopic spring 603;

[0059] S7. After the well tray 1 passes through the stacking locking mechanism 6, it contacts the empty well tray 14 on the spring push plate 5 under the push of the rake-shaped push rod 901. The well tray 1 and the empty well tray 14 are stacked. At the same time, the spring push plate 5 compresses the push plate spring 12. After the sensor C13 detects the compression signal, it transmits the signal to the control system 4. The control system 4 transmits the signal to the lateral pushing device 9, which controls the rake-shaped push rod 901 to return to the initial position.

[0060] S8, the spring push plate 5 moves under the action of the push plate spring 12, and when it moves to the opened movable baffle 602, the movable baffle 602 presses against the edge groove of the hole tray 1 to complete the locking. This reciprocating operation is repeated until the hole tray compresses the spring push plate 5 to the set position. The sensor C13 transmits a signal to the control system 4, and then reminds the control system 4 to take out the stacked hole trays through the switch door 7.
