[0002] Vegetable seeds are seeds used to produce vegetables. Seed packaging machines generally assemble them in a quantitative manner during the assembly process, but sometimes they also adjust the amount of packaged seeds to form products of various specifications. Therefore, the feed amount of the seed packaging needs to be adjusted.

[0003] For example, the Chinese patent with the publication number CN218144477U discloses a device for adjusting the feeding amount of vegetable seed packaging, including a base, a rectangular frame fixedly mounted on the left side of the bottom end of the inner wall of the base, a packaging bag tray slidably connected to the inner wall of the rectangular frame, a screw rod sleeved on the rear end of the packaging bag tray, a suction cup moving device fixedly mounted on the middle part of the bottom end of the inner wall of the base, an extraction tray slidably connected to the left side of the middle part of the suction cup moving device, and a placement tray on the sliding connection side of the middle part of the suction cup moving device. Through the coordinated use of the feed pipe, the second capillary, the first solenoid valve, the cylindrical meter, the second solenoid valve, the first capillary, and the discharge pipe, the second capillary and the second solenoid valve are lowered to the lowest point, the cylindrical meter can be taken out and replaced with a cylindrical meter of different capacity, thereby solving the problem of being unable to adjust the seed feeding amount.

[0004] However, this patent requires replacement of the cylindrical meter when adjusting the seed feed amount. The disassembly and installation process of the cylindrical meter is time-consuming, inconvenient for operators to use, and multiple cylindrical meters need to be prepared, each of which needs to be equipped with a sensing convex head, thereby increasing the cost of vegetable seed packaging.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Example: Refer to Figures 1 to 3 The utility model discloses a device for adjusting the feeding amount of vegetable seeds packaging, comprising a packaging machine body 1, a silo 2 is provided on the top of the packaging machine body 1, a discharge pipe 3 is fixedly penetrated on the lower half of one side of the silo 2, a metering pipe 4 and an output pipe 5 are provided on one side of the packaging machine body 1, the discharge pipe 3, the metering pipe 4 and the output pipe 5 are connected in series in sequence to form a discharge channel, the metering pipe 4 comprises an upper pipe 41, a metering cylinder 42 and a lower pipe 43 from top to bottom, the outer circumferences of the upper pipe 41 and the lower pipe 43 are respectively fixedly sleeved with a first solenoid valve 6 and a second solenoid valve 7, a control part 8 is provided on one side of the packaging machine body 1, and an adjusting part 9 is provided in the metering cylinder 42.

[0023] In this embodiment, the seeds are stored in the silo 2, and the discharge pipe 3 is connected to the silo 2, so the seeds will enter the discharge pipe 3. During the feeding process, the first solenoid valve 6 is opened and the second solenoid valve 7 is closed, so the seeds in the silo 2 will enter the metering pipe 4 through the discharge pipe 3 until the metering pipe 4 is filled. When the second solenoid valve 7 is opened, the seeds in the metering pipe 4 will completely pass through the output pipe 5 and enter the packaging bag, so the seed feeding amount can be adjusted by adjusting the containing volume of the metering pipe 4.

[0024] The upper tube 41 and the lower tube 43 are both connected to the metering cylinder 42. The packaging bag is placed directly below the output tube 5.

[0025] In a further preferred embodiment of the present invention, Figure 3As shown, the adjusting part 9 includes a plurality of annular grooves 91 opened on the inner bottom wall of the metering cylinder 42, the plurality of annular grooves 91 are concentrically arranged, an annular baffle 92 is slidably connected in the annular groove 91, a plurality of electric push rods 93 are fixedly connected to the inner bottom wall of the annular groove 91, and the output ends of the corresponding plurality of electric push rods 93 are commonly fixedly connected to the bottom surface of the corresponding annular baffle 92.

[0026] In this embodiment, the electric push rod 93 drives the annular baffles 92 to move vertically, so that each annular baffle 92 contacts the inner top wall of the metering cylinder 42 or is completely retracted into the corresponding annular groove 91, thereby adjusting the size of the space between the metering cylinder 42 and the upper tube 41 and the lower tube 43, and then adjusting the amount of seeds that can enter the metering cylinder 42.

[0027] In a further preferred embodiment of the present invention, Figure 3 As shown, the inner bottom wall of the metering cylinder 42 is arranged to be inclined downward on the side close to the lower tube 43 .

[0028] In this embodiment, the inner bottom wall of the metering cylinder 42 is inclined downward on the side close to the lower tube 43 to ensure that the seeds in the metering cylinder 42 can be completely discharged from the metering cylinder 42 when the second solenoid valve 7 is opened, and when the annular baffle 92 is retracted into the annular groove 91, the top surface of the annular baffle 92 is coplanar with the inner bottom wall of the metering cylinder 42 to prevent the seeds from being stuck in the annular groove 91.

[0029] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the control unit 8 includes an infrared sensor 81 fixedly mounted on one side of the packaging machine body 1, and a sensing boss 82 is fixedly installed on the outer peripheral side of the upper tube 41 near the infrared sensor 81, and the sensing boss 82, the first solenoid valve 6 and the second solenoid valve 7 are all electrically connected to the infrared sensor 81.

[0030] In this embodiment, when the seeds fill the metering tube 4, the infrared sensor 81 senses that the seeds touch the sensor protrusion 82, and drives the first electromagnetic valve 6 to close and the second electromagnetic valve 7 to open, and the seeds enter the packaging bag through the lower tube 43 and the output tube 5. This control method is the same as the control method in the cited patent document, and will not be repeated here.

[0031] In a further preferred embodiment of the present invention, Figure 2 As shown, a vibration motor 10 is fixedly connected to the outer wall of the metering cylinder 42 , and the discharge pipe 3 and the output pipe 5 are both fixedly connected to the metering pipe 4 through a pipe flexible joint 11 .

[0032] In this embodiment, the vibration motor 10 drives the metering tube 4 to vibrate, so that the seeds in the metering cylinder 42 are shaken to fill the metering cylinder 42, thereby avoiding gaps in the metering cylinder 42 and ensuring the quantitative effect of seed feeding.

[0033] In a further preferred embodiment of the present invention, Figure 1 As shown, a fixing plate 12 is fixedly connected to one side of the packaging machine body 1 , and the output pipe 5 is fixedly passed through the fixing plate 12 .

[0034] In this embodiment, the fixing plate 12 can keep the output pipe 5 fixed, thereby reducing the swing amplitude of the metering cylinder 42 during vibration, and preventing the metering cylinder 42 from swinging excessively and causing the pipeline flexible joint 11 to age quickly.

[0035] The implementation principle of the above embodiment is:

[0036] The packaging bag is placed directly below the output tube 5. In the initial state, the first solenoid valve 6 is closed and the second solenoid valve 7 is opened. The seeds enter the metering tube 4 through the discharge tube 3 until the metering tube 4 is filled. The infrared sensor 81 senses that the seeds contact the sensing protrusion 82 and drives the first solenoid valve 6 to close and the second solenoid valve 7 to open. The seeds enter the packaging bag through the lower tube 43 and the output tube 5.

[0037] When the seed feed rate needs to be adjusted, the corresponding electric push rod 93 is driven to work, driving the annular baffle 92 to move vertically, so that each annular baffle 92 contacts the inner top wall of the metering cylinder 42 or is completely retracted into the corresponding annular groove 91, thereby adjusting the size of the space between the metering cylinder 42 and the upper tube 41 and the lower tube 43, and then adjusting the amount of seeds that can enter the metering cylinder 42.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
