Description

Technical Field

[0001] This utility model relates to the field of tobacco planting equipment, specifically a tobacco seedling tray delivery device with a seedling tray recovery structure. Background Technology

[0002] In tobacco cultivation, seedlings are usually nurtured in seedling trays. When the seedlings grow to a certain stage, the seedling trays need to be transported to the planting area for transplanting. Currently, there is a lack of seedling tray recycling facilities to collect the used seedling trays.

[0003] In related technologies, existing seedling trays usually need to be manually picked up and taken to a designated recycling location after use, which increases the intensity of manual labor. Some specialized seedling tray recycling devices use a tray delivery device with a single conveyor belt to transport the seedling trays. However, the single tray delivery structure is not equipped with a dedicated seedling tray recycling structure, and manual labor is still required to collect the seedling trays at the end of the delivery. This still requires additional manual collection and does not reduce labor costs. Utility Model Content

[0004] The purpose of this invention is to provide a tobacco seedling delivery device with a seedling tray recycling structure, so as to solve the technical problem mentioned in the background art that the seedling trays need to be collected manually, thereby increasing labor costs.

[0008] A recycling mechanism for recycling seedling trays is provided at the inclined bottom end of the guide frame. The recycling mechanism includes a collection component and a lifting component, wherein the lifting component is used to lift the seedling trays onto the collection component.

[0009] The collection component includes a collection frame with four vertical columns. Each column of the collection frame has a bearing block installed at equal intervals along the vertical direction via a hinge, allowing the bearing block to rotate around the hinge. Each column of the collection frame also has a limit block installed at equal intervals, with each limit block corresponding to a bearing block. The limit block is used to limit the rotation angle of the corresponding bearing block.

[0010] The lifting assembly includes a lifting plate located within the area enclosed by the four columns of the collection frame. Both sides of the outer wall of the lifting plate are vertically slidingly engaged with both sides of the inner wall of the collection frame, ensuring that the lifting plate does not deviate when moving vertically along the collection frame. The lifting plate located at the lower end of the lifting stroke is positioned below the inclined bottom end of the guide frame.

[0011] Furthermore, the delivery institutions include:

[0012] The main rotating rollers are rotatably mounted at both ends inside the support frame, and main rotating wheels are equidistantly fitted on the surface of both sets of main rotating rollers; the rotation of the main rotating rollers is driven by a drive motor.

[0013] The auxiliary roller is rotatably mounted on the inside of the support frame. The surface of the auxiliary roller is equidistantly fitted with auxiliary wheels. The surfaces of both the main wheel and the auxiliary wheel are surrounded by a conveyor belt.

[0014] Furthermore, a first gear is fixedly mounted on one end of the main roller, and the first gear is located on one side of the outer wall of the support frame;

The end of the connecting rod away from the eccentric wheel is hinged to one side of the outer wall of the lifting plate through a hinge.

[0020] Furthermore, it also includes a spraying mechanism for cleaning the seedling trays, which is located at the top of the recycling mechanism.

[0021] Furthermore, the spraying mechanism includes:

[0022] The mounting frame is fixedly installed at the bottom of the collection rack. Spray pipes are installed at equal intervals at the top of the mounting frame through the mounting sleeve. Spray nozzles are connected at equal intervals at the bottom of several sets of spray pipes through pipes. A connecting pipe is connected through one end of several sets of spray pipes.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0039] like Figure 1 As shown, in a preferred embodiment of the present invention, a tobacco seedling tray delivery device with a seedling tray recycling structure is provided. The tobacco seedling tray delivery device includes a support frame 1, one end of which is fixedly connected to a guide frame 101. The guide frame 101 is set with an inclined structure. One end of the support frame 1 is connected to the inclined top end of the guide frame 101, so that the seedling trays falling from the tail end of the support frame 1 onto the guide frame 101 can slide down along the inclined surface of the guide frame 101.

[0040] Furthermore, the inner side of the support frame 1 is rotatably equipped with a tray delivery mechanism 2 for conveying seedling trays, which delivers the seedling trays to the guide frame 101.

[0041] For details, please refer to Figure 1 and Figure 2 The tray feeding mechanism 2 provided in this embodiment includes a main rotating roller 201, an auxiliary rotating roller 203 and a drive motor 207. The main rotating roller 201 is rotatably mounted at both ends inside the support frame 1, and the surface of the main rotating roller 201 is equidistantly fitted with main rotating wheels 202.

[0042] The main rotating wheel 202 is configured in several groups, and the auxiliary rotating rollers 203 are rotatably installed on the inner side of the support frame 1. The surfaces of the auxiliary rotating rollers 203 are all equidistantly fitted with auxiliary rotating wheels 204. The surfaces of the main rotating wheels 202 and the auxiliary rotating wheels 204 are all surrounded by a conveyor belt 205. One end of one group of main rotating rollers 201 is fixedly fitted with a first gear 206, which is located on one side of the outer wall of the support frame 1.

[0043] Furthermore, the bottom mounting base of the drive motor 207 is installed on one side of the outer wall of the support frame 1. The drive motor 207 is used to drive the main rotating roller 201 to rotate. The output shaft of the drive motor 207 is fixedly fitted with a second gear 208, and the surface of the second gear 208 meshes with the surface of the first gear 206.

[0044] In a specific implementation, the tray feeding mechanism 2 provided in this embodiment connects the drive motor 207 to the power supply and starts it. The output shaft of the drive motor 207 drives the first gear 206 to rotate. Since the first gear 206 meshes with the second gear 208, it drives the second gear 208 to rotate. The second gear 208 drives one set of main rollers 201 to rotate at one end inside the support frame 1. Several sets of main rollers 202 mounted on the surface of one set of main rollers 201 can drive several sets of conveyor belts 205 to rotate, realizing the process of conveying the seedling trays to the guide frame 101.

[0045] This utility model achieves continuous operation of the tray feeding mechanism 2 through the above steps, placing the seedling trays on several sets of conveyor belts 205, which facilitate the transmission of the rotating sets of conveyor belts 205 to transport the seedling trays, so that the transported seedling trays are guided to the lifting plate 501 through the guide frame 101.

[0046] Preferably, the seedling tray structure to be recycled is a square seedling tray structure, which has multiple placement slots for placing tobacco seedlings.

[0047] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown in this embodiment of the utility model, a recycling mechanism 3 for recycling seedling trays is provided at one end of the support frame 1.

[0048] The recycling mechanism 3 provided by this utility model includes a collection component 4 and a lifting component 5; the recycling mechanism 3 for recycling seedling trays is set at the inclined bottom end of the guide frame 101, and the lifting component 5 is used to lift the seedling trays onto the collection component 4.

[0049] Specifically, in one implementation of the collection component 4 provided by this utility model, the collection component 4 includes a collection frame 401, the bottom of which stands on the ground, and the collection frame 401 has four vertical columns; the collection frame 401 is located at one end of the support frame 1 near the guide frame 101, and each column of the collection frame 401 is equidistantly mounted with bearing blocks 402 along the vertical direction via hinges, so that the bearing blocks 402 can rotate around the hinges, and each column of the collection frame 401 has... Limiting blocks 403 are also installed at equal intervals. Each limiting block 403 corresponds to a bearing block 402. The limiting block 403 is used to limit the rotation angle of the corresponding bearing block 402. When the bearing block 402 supports the seedling tray, the weight of the seedling tray itself presses down on the force-bearing end of the bearing block 402, causing the bearing block 402 to have a tendency to rotate around its hinge. The limiting block 403 provides limiting support for the bearing block 402, so that the bearing block 402 supports the seedling tray in a horizontal state.

[0050] Furthermore, in one implementation of the lifting component 5 provided by this utility model, the lifting component 5 includes a lifting plate 501, which can also adopt a grid plate structure to facilitate the passage and fall of broken soil.

[0051] The lifting plate 501 is located in the area enclosed by the four uprights of the collection rack 401, allowing the lifting plate 501 to move vertically in the area in front of the four uprights.

[0052] Optional, such as Figure 1As shown, a baffle 404 is provided between the two columns opposite to the guide frame 101 to block the seedling trays that slide off the guide frame 101, so that the seedling trays fall stably onto the lifting plate 501.

[0053] In its initial state, the lifting plate 501 is at the bottom of the collection rack 401;

[0054] The lifting assembly 5 also includes a connecting frame 502, which is fixedly installed on the column of the collection rack 401. A servo motor 503 is mounted on the connecting frame 502 via a mounting base.

[0055] Both sides of the outer wall of the lifting plate 501 are vertically slidably engaged with both sides of the inner wall of the collection rack 401 (e.g., a slider and a groove structure is used, a slider is fixedly installed on the outer wall of the lifting plate 501, and a vertical groove is opened on the side wall of each column of the collection rack 401, so that the slider can move vertically in the groove), so that the movement path of the lifting plate 501 does not deviate when it moves vertically along the collection rack 401. The lifting plate 501 located at the lower end of the lifting stroke is located below the inclined bottom end of the guide frame 101, which makes it easy to send the seedling tray to the lifting plate 501.

[0056] The output shaft of the servo motor 503 is fixedly fitted with an eccentric wheel 504. The end of the eccentric wheel 504 away from the servo motor 503 is hinged to a connecting rod 505. The end of the connecting rod 505 away from the eccentric wheel 504 is hinged to one side of the outer wall of the lifting plate 501 through a hinge.

[0057] When the seedling tray is guided onto the lifting plate 501, the servo motor 503 is started. The output shaft of the servo motor 503 drives the eccentric wheel 504 to rotate. The rotating eccentric wheel 504 drives the connecting rod 505 to move up and down. The moving connecting rod 505 drives the lifting plate 501 to move up and down.

[0058] Optionally, the lifting component 5 of this embodiment can be configured as two sets as needed, which can simultaneously lift both ends of the lifting plate 501, so that the lifting plate 501 is subjected to balanced forces when it moves in the vertical direction.

[0059] As the lifting plate 501 moves upward, the seedling tray on the lifting plate 501 moves upward. At this time, the upward force of the seedling tray resists the bottom of several sets of bearing blocks 402 and flips upward. As the seedling tray continues to rise, the seedling tray releases its resistance to the several sets of bearing blocks 402.

[0060] At this time, several sets of support blocks 402 are reset. Since several sets of limiting blocks 403 are set above one end of several sets of support blocks 402, the several sets of limiting blocks 403 limit the downward flipping of several sets of support blocks 402, so that when several sets of support blocks 402 are removed from the contact of the seedling tray, several sets of support blocks 402 are reset to a horizontal state. At this time, the top of the other end of the horizontal support block 402 supports the bottom of the seedling tray.

[0061] Once the seedling tray is supported by the horizontal support block 402, the servo motor 503 continues to work, driving the eccentric wheel 504 to rotate in the opposite direction, causing the connecting rod 505 and the lifting plate 501 to slowly descend until the seedling tray is placed stably in the preset position. Subsequent seedling trays can be collected one by one on the corresponding support block 402 following the above steps, realizing the recycling of multiple seedling trays. Multiple seedling trays are placed on the collection rack 401.

[0062] It is understood that each of the four uprights of the collection rack 401 in this embodiment of the present disclosure is provided with a support block 402, which can effectively support the four corners of the seedling tray.

[0063] In addition, such as Figure 1 and Figure 5 As shown, in a preferred embodiment of this utility model, a spraying mechanism 6 for cleaning seedling trays can be provided at the top of the recycling mechanism 3. The spraying mechanism 6 is used to spray clean water. According to the requirements of the cleanliness of the seedling trays, the spraying mechanism 6 can be used to spray clean water on the multiple seedling trays collected on the collection rack 401 to achieve the cleaning of the seedling trays.

[0064] Specifically, in this embodiment of the utility model, the spraying mechanism 6 includes:

[0065] Mounting bracket 601 is fixedly installed on the top of collection rack 401. Spray pipes 602 are equidistantly installed on the top of mounting bracket 601 through mounting sleeve. Spray nozzles 603 are equidistantly connected to the bottom ends of several sets of spray pipes 602 through pipes. A connecting pipe 604 is connected to one end of each set of spray pipes 602.

[0066] The bottom end of the suction pump 605 is mounted on one side of the outer wall of the collection rack 401 via a mounting base. The output end of the suction pump 605 is connected to the input end of the connecting pipe 604 via a pipeline. The input end of the suction pump 605 is connected to a control valve 606 via a pipeline. The pipeline containing the control valve 606 is connected to an external water supply system.

[0067] A water supply system is connected to the outside of the pipeline to provide water. Then, the control valve 606 is opened, and the suction pump 605 is started. The suction pump 605 generates suction to draw water. The drawn water is delivered to the inside of the connecting pipe 604 through the output end of the suction pump 605. The connecting pipe 604 then distributes the water to the inside of several sets of spray pipes 602. The water is then sprayed out through several sets of nozzles 603. The sprayed water cleans the recycled seedling trays to prevent soil residue from affecting the next use.

[0068] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
