Description

Technical Field

[0001] The utility model relates to the technical field of seedling tray stacking equipment, in particular to a seedling tray buffering and deceleration device. Background Art

[0002] The seedling tray stacking equipment is a device used to automatically stack seedling trays. After the seedling trays are transported to the stacking station by the conveying mechanism, they are stacked by the lifting mechanism. Since the seedling trays need to be ensured to stop at the correct position when they are transported to the stacking station, a seedling tray limiting mechanism is usually set at the tail of the conveying mechanism, forcing the seedling tray to stop moving when it reaches the correct position. However, this type of seedling tray stopping method is to stop the seedling tray by hitting the limiting mechanism, so it may cause damage to the seedling tray. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a rice seedling tray buffer deceleration device, the specific technical solution is as follows:

[0004] A seedling tray buffering and deceleration device is used to be installed at the tail end of a conveying mechanism of a seedling tray stacking device, comprising:

[0005] A mounting base, used for mounting on a seedling tray stacking device;

[0006] A buffer module is provided on the mounting seat and includes a telescopic component and a control component, wherein the control component is connected to the telescopic component and is used to control the telescopic component to extend and retract;

[0007] The receiving module is arranged at the end of the telescopic component and is used for receiving the seedling tray.

[0008] According to the seedling tray buffering and deceleration device according to claim, the telescopic assembly comprises:

[0009] a pressure sleeve connected to the mounting seat;

[0010] The telescopic rod has one end connected to the receiving module and the other end movably sleeved in the pressure sleeve.

[0011] According to the seedling tray buffer deceleration device according to the claim,

[0012] A piston is provided at one end of the telescopic rod away from the receiving module, and a pressure chamber is formed between the piston and the inner wall of the pressure sleeve;

[0013] The control component is a pneumatic control structure or a hydraulic control structure, and the pneumatic control structure or the hydraulic control structure is connected to the pressure chamber.

[0014] According to the rice seedling tray buffering and deceleration device according to claim, the control component includes a solenoid valve, and the solenoid valve is arranged on the pressure sleeve at a position relative to the pressure chamber.

[0015] According to the seedling tray buffering and deceleration device according to claim, the control component further includes a sensing element, and the sensing element is connected to the buffer module.

[0016] According to the seedling tray buffer deceleration device according to the claim,

[0017] The pressure chamber is located at an end of the pressure sleeve away from the receiving module;

[0018] The sensing element includes an air pressure cavity and an air pressure sensor. The air pressure cavity is located in the pressure sleeve at one end away from the pressure cavity, and the air pressure sensor is connected to the air pressure cavity.

[0019] According to the seedling tray buffering and deceleration device according to any one of claims 1 to 4, the mounting seat is a lifting structure, and the lifting structure includes:

[0020] base;

[0021] A lifting platform is provided on the base;

[0022] A connecting plate is connected between the lifting platform and the pressure sleeve.

[0023] According to the seedling tray buffering and deceleration device according to any one of claims 1 to 4, the receiving module includes a receiving plate, and the receiving plate is arranged perpendicular to the axis of the telescopic rod.

[0024] The rice seedling tray buffering and deceleration device provided by the utility model is realized by arranging a buffer module and a receiving module on a mounting seat, and detecting whether the rice seedling tray touches or approaches the receiving module through a control component in the buffer module, so that when the rice seedling tray touches or approaches the receiving module, the control component can control the telescopic component to extend or shorten the telescopic component, thereby driving the receiving module to move synchronously along the rice seedling tray movement direction at a speed lower than the rice seedling tray movement speed, and gradually reducing the movement speed until it stops. After stopping, the receiving module forces the rice seedling tray to stop accurately at the stacking station. Since the telescopic component and the receiving module start to perform deceleration movement from receiving the rice seedling tray, the moving rice seedling tray stops slowly, and is therefore not easy to cause damage to the rice seedling tray, thereby solving the problems in the background technology.

[0036] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0037] It should be noted that similar reference numerals denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in the subsequent drawings.

[0038] It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate and simplify the description of the utility model and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation.

For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0040] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components.

[0041] See Figures 1 to 5 This embodiment provides a seedling tray buffering and deceleration device, which is used to be installed at the tail end of the conveying mechanism 110 of the seedling tray stacking equipment 100, including a mounting seat 1, a buffer module 2 and a receiving module 3.

[0042] The mounting base 1 is used for being mounted on the seedling tray stacking device 100 .

[0043] The buffer module 2 is arranged on the mounting seat 1 and includes a telescopic component 21 and a control component 22 . The control component 22 is connected to the telescopic component 21 and is used to control the telescopic component 21 to extend and retract.

[0044] The receiving module 3 is provided at the end of the telescopic assembly 21 and is used to receive the seedling tray 200 .

[0045] The telescopic assembly 21 can be driven by hydraulic pressure or pneumatic pressure, and the control assembly 22 can detect whether the seedling tray 200 touches or approaches the receiving module 3. When the seedling tray 200 touches or approaches the receiving module 3, the telescopic assembly 21 is activated, causing the telescopic assembly 21 to extend or shorten, thereby driving the receiving module 3 to move synchronously along the movement direction of the seedling tray 200 at a speed lower than the movement speed of the seedling tray 200, and gradually reducing the movement speed until it stops. After stopping, the receiving module 3 forces the seedling tray 200 to stop accurately at the stacking station. Since the telescopic assembly 21 and the receiving module 3 start to decelerate from receiving the seedling tray 200, the moving seedling tray 200 slowly stops, thereby not easily damaging the seedling tray 200. It should be noted that in order to ensure that the control assembly 22 can accurately detect the positional relationship between the seedling tray 200 and the receiving module 3, the control assembly 22 can include detection elements such as position sensors.

[0046] The seedling tray buffering and deceleration device provided in this embodiment is configured by arranging a buffer module 2 and a receiving module 3 on the mounting seat 1, and detecting whether the seedling tray 200 touches or approaches the receiving module 3 through the control component 22 in the buffer module 2, so that when the seedling tray 200 touches or approaches the receiving module 3, the control component 22 can control the telescopic component 21 to extend or shorten the telescopic component 21, thereby driving the receiving module 3 to move synchronously along the movement direction of the seedling tray 200 at a speed lower than the movement speed of the seedling tray 200, and gradually reducing the movement speed until it stops. After stopping, the receiving module 3 forces the seedling tray 200 to stop accurately at the stacking station. Since the telescopic component 21 and the receiving module 3 start to perform deceleration movement from receiving the seedling tray 200, the moving seedling tray 200 slowly stops, so it is not easy to cause damage to the seedling tray 200, thereby solving the problems in the background technology.

[0047] Further, see Figure 3 The telescopic assembly 21 includes a pressure sleeve 211 and a telescopic rod 212 .

[0048] The pressure sleeve 211 is connected to the mounting seat 1 .

[0049] One end of the telescopic rod 212 is connected to the receiving module 3 , and the other end is movably sleeved in the pressure sleeve 211 .

[0050] Among them, the control component 22 can be connected to the pressure sleeve 211 or the telescopic rod 212. When the control component 22 is connected to the pressure sleeve 211, the control component 22 can control the extension and retraction of the telescopic rod 212 through hydraulic or pneumatic pressure; when the control component 22 is connected to the telescopic rod 212, the control component 22 can control the extension and retraction of the telescopic rod 212 through a motor.

[0051] For further information, please see Figure 3 , in the examples provided in this embodiment:

[0052] A piston 213 is provided at one end of the telescopic rod 212 away from the receiving module 3 , and a pressure chamber 214 is formed between the piston 213 and the inner wall of the pressure sleeve 211 .

[0053] The control assembly 22 is a pneumatic control structure or a hydraulic control structure, which is connected to the pressure chamber 214 and can extend or shorten the telescopic rod 212 by injecting or discharging gas or liquid in the pressure chamber 214.

[0054] For further information, please see Figure 3 The control component 22 includes a solenoid valve 221 , which is disposed on the pressure sleeve 211 relative to the pressure chamber 214 .

[0055] The solenoid valve 221 can be connected to an external pressure pumping source, and the solenoid valve 221 can accurately control the pressurization or pressure relief in the pressure chamber 214 to achieve precise control of the telescopic rod 212.

[0056] Furthermore, the control component 22 further includes a sensing element 222 , and the sensing element 222 is connected to the buffer module 2 .

[0057] The sensing element 222 can be used to accurately detect whether the seedling tray 200 touches or approaches the receiving module 3 .

[0058] Further, see Figure 3 , in the examples provided in this embodiment:

[0059] The pressure chamber 214 is located at an end of the pressure sleeve 211 away from the receiving module 3 .

[0060] The sensing element 222 includes an air pressure chamber 222a and an air pressure sensor 222b. The air pressure chamber 222a is located in the pressure sleeve 211 at one end away from the pressure chamber 214, and the air pressure sensor 222b is connected to the air pressure chamber 222a.

[0061] Among them, the air pressure chamber 222a can be connected to an external air pressure extraction source and can be precisely controlled through a program so that the pressure inside the air pressure chamber 222a is consistent with the pressure inside the pressure chamber (214). The air pressure chamber 222a can be much smaller than the pressure chamber 214, so that the pressure change inside the air pressure chamber 222a is more sensitive to the change of external pressure. After the seedling tray 200 touches the receiving module 3, the air pressure sensor 222b can quickly capture the pressure change, thereby controlling the telescopic component 21.

[0062] Further, see Figure 1 The mounting seat 1 is a lifting structure, which includes a base 11, a lifting platform 12 and a connecting plate 13.

[0063] The lifting platform 12 is disposed on the base 11 .

[0064] The connecting plate 13 is connected between the lifting platform 12 and the pressure sleeve 211 .

[0065] Among them, the lifting platform 12 can be connected to the base 11 through a hydraulic rod or a pneumatic rod, the connecting plate 13 can be an "L"-shaped metal sheet, and the pressure sleeve 211 is installed on the lifting platform 12 through the "L"-shaped metal sheet, so that the receiving module 3 can rise and fall synchronously when the lifting platform 12 is raised or lowered, so that when the seedling tray 200 is lifted by the lifting mechanism on the stacking station, the receiving module 3 can support the seedling tray 200.

[0066] Furthermore, the receiving module 3 includes a receiving plate 31 , which is arranged perpendicular to the axis of the telescopic rod 212 to receive the transported seedling tray 200 .

[0067] Working principle:

[0068] The telescopic assembly 21 can be driven by hydraulic pressure or pneumatic pressure. The control assembly 22 can detect whether the seedling tray 200 touches or approaches the receiving module 3. When the seedling tray 200 touches or approaches the receiving module 3, the telescopic assembly 21 is activated, causing the telescopic assembly 21 to extend or shorten, thereby driving the receiving module 3 to move synchronously along the movement direction of the seedling tray 200 at a speed slower than the movement speed of the seedling tray 200, and gradually reducing the movement speed until it stops. After stopping, the receiving module 3 forces the seedling tray 200 to stop accurately at the stacking station. Since the telescopic assembly 21 and the receiving module 3 start to decelerate from receiving the seedling tray 200, the moving seedling tray 200 slowly stops, thereby reducing the risk of damage to the seedling tray 200. It should be noted that in order to ensure that the control assembly 22 can accurately detect the positional relationship between the seedling tray 200 and the receiving module 3, the control assembly 22 may include detection elements such as position sensors.

The above is only a preferred implementation method of the present invention.
