Description

Technical Field

[0001] The present invention belongs to the field of agricultural machinery transplanting, and particularly relates to an ejection-type high-speed planting test device. Background Art

[0002] At present, the vegetable seedling transplanting technology has become an important means of vegetable production. It has the advantages of alleviating seasonal contradictions and improving the survival rate of seedlings, and can significantly improve economic benefits. The transplanting methods currently used in China are mostly manual transplanting or semi-automatic mechanized transplanting. Manual transplanting is time-consuming and laborious, and it is difficult to guarantee the transplanting quality. It is not suitable for large-area transplanting, which restricts the production efficiency. Mechanized transplanting can complete multiple processes such as hole punching, seedling planting, and soil covering at one time, and the roots of the transplanted seedlings are developed, grow uniformly, and are convenient for management. In agronomy, there are corresponding requirements for the uprightness of the planted seedlings. Good uprightness can ensure the normal growth of vegetable seedlings. The planting process of mechanized transplanting has a great impact on the quality of planted seedlings. To ensure the uprightness and quality of planted seedlings, the planting speed of the transplanter is usually slow. At present, there are few high-speed planting devices. The planting mechanism improves the planting speed by optimizing the movement trajectory of the bottom end of the planter, the inclination angle of the hanging cup, the connecting rod parameters, etc. However, the planting speed of the currently used transplanter is usually about 40 plants per minute, and the planting speed of the optimized prototype is mostly about 80 plants per minute. If the speed is increased further, the quality of the planted seedlings will seriously decline. This is because after the planter punches a hole, the pot seedlings in the cup fall into the hole under the action of their own gravity. As the planting speed increases, when the planter reaches the planting point, the pot seedlings have not yet fallen to the bottom of the planter due to their own gravity, resulting in a decrease in the uprightness of the planted seedlings and poor quality of the planted seedlings. Summary of the Invention

[0003] In order to overcome the above deficiencies, the present invention designs an ejection-type high-speed planting test device, which applies an external force during the falling process of the pot seedlings by means of ejection and pressing, so that the pot seedlings can smoothly reach the planting point with the planter during high-speed transplanting, thereby enabling the design and optimization of the planting mechanism during the high-speed planting process.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A catapult-type high-speed planting test device, comprising a soil trough, a soil trough conveyor, a synchronous belt linear module, a frame, a planting device, a high-speed camera, and a computer. The soil trough conveyor is fixedly placed on the ground, and the soil trough is arranged on the soil trough conveyor, but needs to be placed in the center; the frame straddles the soil trough conveyor and is horizontally centered along the conveying direction; the synchronous belt linear module is installed on the frame, including a first synchronous belt linear module, a second synchronous belt linear module, a third synchronous belt linear module, and a fourth synchronous belt linear module. The first synchronous belt linear module and the second synchronous belt linear module are placed side by side along the conveying direction and are vertically installed at both ends of the frame in the conveying direction to provide horizontal movement for the planting device. The third synchronous belt linear module spans above the frame and is installed on the first synchronous belt linear module and the second synchronous belt linear module. The fourth synchronous belt linear module is vertically placed and installed on the third synchronous belt linear module to provide vertical movement for the planting device; the planting device is arranged side by side with the third synchronous belt linear module and is installed on the third synchronous belt linear module; the high-speed camera is arranged between the soil trough conveyor and the third synchronous belt linear module, used to collect picture information during the planting process and upload it to the computer for planting quality analysis.

[0006] Further optimization: The duckbill tilting device includes a motor, a turbine, a worm, a motor housing, an L-shaped plate, a duckbill planter, a seedling cup fixing ring, and a vertical seedling feeding box. The L-shaped plate is installed on the third synchronous belt linear module, and the motor housing is fixed on the L-shaped plate. The motor is installed in the motor housing and is connected to the worm. The turbine is assembled on the worm, and the turbine is connected to the seedling cup fixing ring. The duckbill planter is fixed on the seedling cup fixing ring. The duckbill planter is tilted back and forth along the conveying direction by the motor, and the seedling loading port of the duckbill planter is exactly located at the lower seedling feeding port of the vertical seedling feeding box.

[0007] Further optimization: The vertical seedling feeding box includes a box body, a box body fixing rod, a conveyor belt with partitions, a tension pulley, and an ejection and pressing device. The fixing rod spans above the frame and is installed on the first synchronous belt linear module and the second synchronous belt linear module, and is arranged side by side with the third synchronous belt linear module. The box body is installed on the fixing rod, and the seedling outlet is located above the duckbill seedling loading port. The conveyor belt with partitions and the tension pulley are both installed in the box body and are used for vertically transporting pot seedlings, suitable for the height of vegetable pot seedlings during the transplanting period. The ejection and pressing device is arranged below the partition. An arc-shaped convex block is fixed at a position in the left side of the box body, less than one partition away from the seedling outlet. This arc-shaped convex block is used to activate the ejection and pressing device. Arc-shaped convex blocks are fixed at symmetrical positions on the right side and the left side of the box body inside the box to restore the ejection and pressing device to the pre-tightened state.

[0008] For further optimization, the ejection and pressing device includes a sleeve, a telescopic rod, a first connecting rod, a second connecting rod, a first spring, a second spring, a pulling rope, and a rubber plate. The sleeve is fixed below the partition of the conveyor belt with a partition. A telescopic rod is installed in the sleeve. A first spring is provided between the telescopic rod and the bottom end of the sleeve. The lower end of the telescopic rod is connected to the end of the second connecting rod. The first connecting rod is used to connect the second connecting rod and the sleeve. The rubber plates are placed horizontally and symmetrically. The rubber plates are connected to the lower end of the partition through the second spring. A pulling rope is provided at the lower end of the telescopic rod. The pulling rope is connected to the convex end of the rubber plate, and the rubber plate presses down on the pot seedling substrate.

[0009] For further optimization, the first synchronous belt linear module and the second synchronous belt linear module are connected by a synchronous belt connecting rod.

[0010] For further optimization, the third synchronous belt linear module is perpendicular to the conveying direction of the soil trough conveying device.

[0011] For further optimization, the duckbill tilting device is connected to the fourth synchronous belt linear module through an L-shaped plate.

[0012] For further optimization, the distance between the partitions is 145 - 175 mm.

[0013] The beneficial effects of the present invention are as follows:

[0014] The present invention simulates the forward state of the transplanting machine through the conveyor belt and the soil trough, and simulates the planting process during high-speed transplanting through the synchronous belt linear module. The two cooperate with each other to basically achieve the "zero-speed seedling throwing" principle. And through the vertical seedling feeding and ejection and pressing device, the falling speed of the pot seedlings is broken through the natural state, and the subsequent planting test can be carried out smoothly. Moreover, the test device can be equipped with a mechanical seedling taking device, and planting mechanisms such as a transparent planter, a multi-rod type, and a planetary gear type can be replaced, and different soils can be replaced for further tests. The present invention can enable the pot seedlings to move smoothly with the planter to the planting point during high-speed transplanting, conduct planting tests during high-speed transplanting, and at the same time be equipped with a high-speed camera and computer processing and analysis, which is convenient for overall tests of the seedling planting mechanism and the soil, and reverse-pushing and optimizing the planting structure parameters, and has good versatility.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention.

[0023] An ejection-type high-speed planting test device for conducting planting tests in high-speed transplanting, including a soil trough 1 and a soil trough conveyor 2. The soil trough 1 is placed on the soil trough conveyor 2 and centered. The frame 3 spans across the soil trough conveyor 2 and is centered along the conveying direction. At both ends of the frame 3 along the direction perpendicular to the conveying direction, a first synchronous belt linear module 6 and a second synchronous belt linear module 7 are respectively installed, and the two are connected by a synchronous belt connecting rod 13 to ensure operation at the same working speed. The third synchronous belt linear module 8 is perpendicular to the conveying direction and is horizontally installed on the first synchronous belt linear module 6 and the second synchronous belt linear module 7. The fourth synchronous belt linear module 9 is vertically installed on the third synchronous belt linear module 8, and the lowest end should be higher than the soil trough conveyor 2 and lower than the highest point of the soil trough 1 in the vertical direction. The duckbill tilting device 12 is connected to the fourth synchronous belt linear module 9 through an L-shaped plate 11. The box body fixing rod 10 spans across the frame 3, is arranged side by side with the third synchronous belt linear module 8 along the conveying direction, and is installed on the first synchronous belt linear module 6 and the second synchronous belt linear module 7. A vertical seedling feeding box 4 is installed on the box body fixing rod 10, and the seedling outlet is located directly above the duckbill planter 1207. The high-speed camera 5 is placed on the same side as the duckbill planter 1207, and is centered under the frame 3, with a height higher than the soil trough conveyor 2 and lower than the lower end of the vertical seedling feeding box 4.

[0024] The duckbill tilting device 12 includes a motor housing 1201 fixed to the L-shaped plate 11, a motor 1202 fixed inside the motor housing 1201, a worm 1203 connected to the output shaft of the motor 1202, a turbine 1204 engaged with the worm 1203 for movement, and a seedling cup fixing ring 1206 connected through a turbine connecting shaft 1205. The duckbill planter 1207 is fixed in the middle of the seedling cup fixing ring 1206, and the motor 1202 is used to tilt the duckbill planter 1207 by the required angle.

[0025] The vertical seedling feeding box 4 includes a box body 401 fixed to the box body fixing rod 10. Inside the box body, a tension wheel 404 is installed in the vertical direction perpendicular to the conveying direction. The vertical conveyor belt 402 is installed closely against the tension wheel 404. Partition plates 403 are installed on the vertical conveyor belt 402 at equal intervals, with a spacing of approximately 160 mm, suitable for vegetable plug seedlings 14 during the transplanting period. An ejection and pressing device is installed below the partition plate 403. An arc-shaped convex block 405 is fixed at a position in the left side (the descending direction of the vertical conveyor belt 402) of the box body 401 and less than one partition plate 403 away from the seedling outlet to activate the ejection and pressing device 15. An arc-shaped convex block 405 is also fixed at a symmetric position on the right side (the ascending direction of the vertical conveyor belt 402) of the box body 401 to restore the ejection and pressing device 15 to the pre-tightened state.

[0026] The ejection and pressing device 15 includes a sleeve 1501 fixed below the partition plate 403, with a telescopic rod 1503 installed inside. A spring 1502 is installed between the telescopic rod 1503 and the bottom end of the sleeve 1501. The lower end of the telescopic rod 1503 is connected to the end of a connecting rod two 1506. A connecting rod one 1504 is used to connect the connecting rod two 1505 and the sleeve 1501. A set of rubber plates 1507 are placed horizontally and symmetrically, and are connected to the lower end of the partition plate 403 through a spring 1506. Two pull ropes 1508 are fixed to the lower end of the telescopic rod 1503, and the pull ropes 1508 are connected to the convex ends of the rubber plates 1507.

[0027] Further, a rectangular hole is provided at the middle position of the sleeve 1501, and a wedge-shaped buckle is provided on the telescopic rod 15 - 3. When the telescopic rod 1503 rises, the buckle will enter the rectangular hole to reach a locked state. When an external force is applied again, the wedge-shaped buckle will disengage from the rectangular hole, and under the action of the spring 1502, the telescopic rod 1503 will move downward in the vertical direction.

[0028] The working process of the present invention is as follows:

[0029] The catapult-type high-speed planting test device makes the soil trough 1 move along the conveying direction through the soil trough conveying device 2. The first synchronous belt linear module 6, the second synchronous belt linear module 7 drive the third synchronous belt linear module 8, the fourth synchronous belt linear module 9, the duckbill tilting device 12, and the vertical seedling feeding box 4 to move in the direction opposite to the conveying direction. The tilting angle of the duckbill planter 1207 is preset in advance, and the pot seedlings 14 are placed in the vertical seedling feeding box 4. The third synchronous belt linear module 8, the fourth synchronous belt linear module 9, the duckbill tilting device 12, and the vertical seedling feeding box 4 are pre-moved to one end of the first synchronous belt linear module 6 and the second synchronous belt linear module 7 opposite to the conveying direction. When the soil trough 1 moves into the range of the frame 3, the vertical seedling feeding box 4 starts to feed the seedlings downward. The fourth synchronous belt linear module 9 drives the entire duckbill tilting device 12 to move downward to simulate the "zero-speed seedling dropping" planting process. The catapult pressing device 15 is initially in a pre-tightened state. During the movement along the vertical conveyor belt 402, the second connecting rod 1505 contacts the convex block 405, causing the telescopic rod 1503 to drop. The rubber plate 1507 is driven through the pull rope 1508 to slap the substrate of the pot seedling 14, so that it drops quickly. Subsequently, during the upward movement of the second connecting rod 1505 along the vertical conveyor belt 402, it contacts the convex block 405 on the other side, causing the telescopic rod 1503 to return to the pre-tightened state; during the planting process, the high-speed camera 5 continuously collects picture information, which is uploaded to the computer for analysis after the end. When there is no overlapping part between the soil trough 1 and the duckbill planter 1207, the test device stops and then resets, and the computer analyzes the seedling planting quality.

[0030] The above shows and describes the main features, usage methods, basic principles, and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments.
