[0019] like Figures 1 to 10 As shown, an embodiment of the present invention provides a pressing device for a seed tray seeding machine, including a bracket 1, a housing 2, pressing heads 16, a protective cover 8 fixed on the housing 2, and a rotating cylinder 15 rotatably disposed inside the protective cover 8.

A motor 7 is connected to the input end of the gearbox 6. The adjusting part is rotatably disposed inside the rotating cylinder 15 and threadedly connected to the pressure head 16. It includes a rotary pusher consisting of a rotating disk 21 rotatably disposed inside the rotating cylinder 15 and a plurality of sliders 23 evenly threadedly connected to the rotating disk 21, and also includes a pusher connected to the rotary pusher to adjust the position of the pressure head 16. The adjusting push part is provided through one of the shafts 26. It includes an adjusting plug consisting of a rubber rod 27 that passes through one of the shafts 26, a support rod 28 that passes through one end of the rubber rod 27, and a crosshead 29 fixed to one end of the support rod 28. The adjusting plug can be inserted into the rotating push part. It also includes an adjusting drive part consisting of a T-plate 40 provided at the other end of the rubber rod 27 and an inclined rubber wheel 50 fixed to the outside of the rubber rod 27. The T-plate 40 is elastically connected to the support rod 28. The cleaning section is provided with a movable through-rotating cylinder 15, which includes a push-pull member consisting of a lead screw 44 that can be slidably disposed in the cylinder 15 and a connecting plate 46 that is threadedly connected to the lead screw 44 and slidably passes through the cylinder. It also includes a wiping member disposed on the outside of the cylinder 15, and the wiping member is connected to the push-pull member to clean the pressure head 16.

[0020] Specifically, the main gear 5 meshes with the secondary gear 14 and the side gear 10. A fixed plate 3 is welded to the outer side of the bracket 1. A fixing hole 13 is formed through the inside of the fixed plate 3, providing a through channel 33 for the fixed components. This allows the fixed plate 3 to provide support for the bracket 1. The bracket 1 can stably support the outer shell 2, which in turn supports the protective cover 8. The protective cover 8 and the outer shell 2 provide protection for their inner components. The outer shell 2 also provides rotational support for the rotating rod 4 and stable support for the transmission 6. The transmission 6 can provide... The motor 7 provides support and can drive the gearbox 6 to run via the drive end. The gearbox 6 drives the rotating rod 4 to rotate at a set speed. The rotating rod 4 can provide support for the main gear 5. The cover 8 can provide rotational support for the rotating rod 9 and the shaft 26. The rotating rod 9 can provide support for the side gear 10. The shaft 26 can provide support for the auxiliary gear 14 and can cooperate with the rubber rod 27 and the insert plate 53 to drive the rotating cylinder 15 to rotate. The rotating cylinder 15 can drive the pressure head 16 to rotate together. The pressure head 16 can squeeze the soil in the pit during rotation to achieve the pitting effect.

[0021] In practical application, the operator can place the pressing device at the work site as needed and fix the fixing plate 3 at the work site through the fixing hole 13 using the fixing component. This allows the fixing plate 3 to stably support the bracket 1. There is a through space between the outer shell 2, the brush, and the pressing head 16, providing a through-moving channel 33 for the seedling trays. The operator can feed the seedling trays from the side of the pressing device near the roller 11 into the through-moving channel 33, allowing the seedling trays to be output from the other side of the pressing device. During the feeding process, the motor 7 needs to be started, causing the motor 7 to drive the rotating rod 4 to rotate counterclockwise through the gearbox 6. The rotating rod 4 will then use the rotational power to drive the main gear 5 and the rotating rod 4 to rotate counterclockwise together under the support of the outer shell 2. The main gear 5 will use the meshing action to drive the side gear 10 to rotate clockwise, causing the side gear 10 to rotate clockwise. The rotating rod 9, supported by the protective cover 8, can be driven to rotate clockwise using rotational power. The rotating rod 9 will then drive the roller 11 to rotate together, which in turn will drive the soft brush 12 to rotate clockwise. The soft brush 12 can use rotational power to smooth and evenly distribute the soil on the pit during rotation. At the same time, the main gear 5 will drive the secondary gear 14 to rotate clockwise using meshing action. The secondary gear 14 will then drive one of the shafts 26 to rotate under the support of the protective cover 8 using rotational power. The shaft 26 will then drive the rubber rod 27 and the insert plate 53 to rotate together. When the insert plate 53 is in the slot 52, it will push the rotating cylinder 15 to rotate clockwise. The rotating cylinder 15 will then drive the pressure head 16 to rotate together using rotational power through the connecting rod 17. The pressure head 16 will alternately press down on the soil in the pit during rotation, performing pit pressing work. This integrates soil equalization and pit pressing structure, reduces space occupation, and improves pit pressing efficiency.

[0022] In a preferred embodiment of the present invention, the rotary pusher further includes: Fixed rod 18 is fixed to the inner wall of the rotating cylinder 15; Sleeve 19 is fixed to the end of fixed rod 18 away from the inner wall of cylinder 15; Rotating shaft 20, rotating through sleeve 19 is provided; The screw-driven component is located on one side of the turntable 21.

[0023] Specifically, the rotating cylinder 15 can provide stable support for the fixed rod 18, the fixed rod 18 can provide stable support for the rotating sleeve 19, and the rotating sleeve 19 can provide rotational support for the rotating shaft 20.

[0024] The screw pusher components include: Turntable 21 is connected to the outside of rotating shaft 20; A flat thread 22 is provided on the side of the turntable 21 near the gearbox 6; The slider 23 is threadedly connected to the flat thread 22.

[0025] Specifically, the rotating shaft 20 can provide support for the turntable 21 and drive the turntable 21 to rotate together. The turntable 21 can provide support for the planar thread 22. The planar thread 22 can use rotational power, rotational direction and thread action to push the slider 23 to move away from or close to the center of the turntable 21.

[0026] The push link includes: Multiple connecting rods 17 are provided, passing through the rotary cylinder 15, and are respectively connected to the pressure head 16; The number of sliders 23 and connecting rods 17 is the same as the number of rows of pressure heads 16; The number of connecting rods 17 is the same as the number of pressure heads 16, and their positions correspond to the positions of pressure heads 16; The support plate 24 has multiple plates, one end of which is fixed to the outside of the slider 23, and the other end is connected to the connecting rod 17 and corresponds to the position of each row of pressure heads 16.

[0027] Specifically, the rotating cylinder 15 provides a through channel 33 for the connecting rod 17 and serves as a guide and limit for movement, and also provides support for the pressure head 16. The slider 23 and the connecting rod 17 provide support for the support plate 24, and the slider 23 can push the connecting rod 17 to move together through the support plate 24 under the action of external force, so that the connecting rod 17 can drive the pressure head 16 to move. The side of the T plate 40 away from the spring 39 is fixed with a handle 41.

[0028] In practical application, before pressing the seedlings into holes, the operator can control the extension of the electric actuator 43 and the retraction of the electric rod 32 according to the different depth requirements of the holes to be pressed in the seedling trays. This allows the electric actuator 43 to use its telescopic end to drive the lead screw 44, connecting plate 46, ring sleeve 47, and slanted wheel 45 to move away from the secondary gear 14, preventing the slanted wheel 45 from contacting the slanted rubber wheel 50. Meanwhile, the electric rod 32, supported by the protective cover 8, uses its telescopic end to drive the push plate 31 towards the turntable 21. The push plate 31, through the bushing 30 and bearing 34, drives the rubber rod 27 to overcome the friction with the shaft 26 and move towards the turntable 21. Simultaneously, the rubber rod 27... This will cause the push plate 51, support rod 28, crosshead 29, and inclined rubber wheel 50 to move together, allowing the crosshead 29 to insert into the cross groove 25 and engage with the rotating shaft 20. Simultaneously, the rubber rod 27 will drive the insert plate 53 to move together, causing the insert plate 53 to move out of the slot 52 and separate from the rotating cylinder 15. Then, the motor 7 will be started, causing the motor 7 to drive the shaft 26 to rotate via the gearbox 6. The shaft 26 will then use friction and rotational power to drive the rubber rod 27 to rotate together. The rubber rod 27, using the bolt 36 and friction pad 37 to fix the support rod 28, will then drive the support rod 28 to rotate together. The support rod 28 will then drive the crosshead 29 to rotate, allowing the crosshead 29 to engage with the cross groove 25 using rotational power. The rotating shaft 20 rotates together with the rotating sleeve 19 and the fixed rod 18. Simultaneously, the rotating shaft 20 drives the planar thread 22 to rotate via the turntable 21. The planar thread 22, utilizing rotational power and thread action, pushes the slider 23, guided by the rotating cylinder 15 and connecting rod 17, to move away from or towards the center of the turntable 21. This allows the slider 23 to move along with the connecting rod 17 via the support plate 24, which in turn pushes the pressure head 16. This adjusts the distance between the pressure head 16 and the rotating cylinder 15, thereby changing the depth of the pressure head 16 in the soil within the pit (the further away the pressure head 16 is from the rotating cylinder 15, the deeper the pressure). Afterwards, electrical control is required. When the moving rod 32 and electric push rod 43 are reset, and the crosshead 29 is observed to be pulled out of the cross groove 25 from the transparent ring 49, the electric rod 32 needs to be stopped from resetting, and the motor 7 is controlled to rotate. The motor 7 uses the main gear 5 and the secondary gear 14 to drive the shaft 26 to rotate, so that the shaft 26 can drive the rubber rod 27, the crosshead 29 and the insert plate 53 to rotate together. After the insert plate 53 is rotated to align with the slot 52, the motor 7 is stopped immediately to maintain the position of the insert plate 53 and the rubber rod 27. Then, the electric rod 32 is controlled to extend and reset, so that the rubber rod 27 overcomes the friction with the shaft 26 and drives the insert plate 53 to move together, so that the insert plate 53 is inserted into the slot 52 to reset. Then the motor 7 can be restarted to perform the cavitation work.

[0029] In another preferred embodiment of the present invention, the adjustment plug-in further includes: Bearing 34 is located on the outside of rubber rod 27; The bushing 30 is fixed to the outside of the bearing 34; Push plate 31 is fixed on bushing 30; The electric rod 32 is fixed to the outer wall of the protective cover 8, and its telescopic end is fixedly connected to the push plate 31. Channel 33 is opened through the axis of the rubber rod 27 and is located on the outside of the support rod 28.

[0030] Specifically, the rubber rod 27 can provide support for the bearing 34, the bearing 34 can provide support for the bushing 30, the bearing 34 can provide rotational support for the rubber rod 27 under the support of the bushing 30, and the electric rod 32 can support the push plate 31 with its telescopic end under the support of the cover 8, so that the push plate 31 can provide support for the bushing 30.

[0031] The adjustment drive also includes: The groove 35 is formed inside the rubber rod 27 and communicates with the channel 33; Bolt 36, threaded through rubber rod 27, extends into groove 35; Friction pad 37 is fixed to the end of bolt 36 and located inside groove 35; Friction pad 37 is in frictional contact with support rod 28; A cross groove 25 is provided at one end of the rotating shaft 20 near the crosshead 29; An inclined rubber wheel 50 is fixed to the outside of the rubber rod 27, and the inclined rubber wheel 50 is located inside the rotating cylinder 15; Transparent ring 49 is fixedly installed through the rotating cylinder 15; Slot 52 is symmetrically opened on the inner wall of one end of the rotating cylinder 15 near the auxiliary gear 14; Insert plate 53 is symmetrically fixed on the outside of rubber rod 27 and located inside slot 52.

[0032] Specifically, the rubber rod 27 provides space for the groove 35, the groove 35 provides space for the friction pad 37 to be stored and moved, the rubber rod 27 provides support for the bolt 36 using its thread, the bolt 36 provides support for the friction pad 37, the friction pad 37 is made of rubber and can use external force and friction to press and fix the support rod 28, the rotating shaft 20 provides space for the cross groove 25, the cross groove 25 provides space for the cross head 29 to be fitted, the rubber rod 27 can drive the inclined rubber wheel 50 to rotate and move together, the transparent ring 49 is made of transparent material, which allows the staff to easily observe the position of the cross head 29, the rubber rod 27, the cross groove 25, the slot 52, the insert plate 53 and the inclined caster through the rotating cylinder 15, the slot 52 provides space for the insert plate 53 to be inserted, and the insert plate 53 can push the rotating cylinder 15 to rotate under the action of external force (when it is in the slot 52).

[0033] Resilient connections include: The telescopic rod 38 is fixed at one end to the end of the support rod 28 and connected to the T-plate 40 at the other end. Spring 39 is sleeved on the outside of telescopic rod 38, with one end fixedly connected to support rod 28 and the other end fixedly connected to T plate 40; The push plate 51 is fixed to the end of the rubber rod 27 and is located outside the T plate 40.

[0034] Specifically, the support rod 28 provides support for the telescopic rod 38 and one end of the spring 39. The telescopic rod 38 provides space for the spring 39 to be fitted and supports the T-plate 40, allowing the T-plate 40 to support the handle 41. The push plate 51 provides storage and positioning for the T-plate 40. The spring 39 and the telescopic rod 38 can extend under external force, and the telescopic rod 38 can be pushed and retracted by the T-plate 40 under the rebound force of the spring 39. The push plate 51 provides positioning for the T-plate 40 and provides redundancy to prevent the support rod 28 from rotating.

[0035] In practical application, before performing acupressure, the operator can pull the T-plate 40 away from the spring 39 using the handle 41. This causes the T-plate 40 to stretch the spring 39 and move it out of the push plate 51. Simultaneously, the operator needs to rotate the bolt 36, using the thread action between the bolt 36 and the rubber rod 27 to move it away from the support rod 28. This causes the bolt 36 to move the friction pad 37 within the groove 35, separating it from the support rod 28 and thus releasing the fixing effect on the support rod 28. Then, the operator can push the telescopic rod 38 and the spring 39 to rotate using the handle and the T-plate 40. This causes the telescopic rod 38 to rotate the support rod 28 within the channel 33, causing the support rod 28 to rotate along with the crosshead 29. The crosshead 29 can then rotate to the angle corresponding to the cross groove 25. After that, the bolt 36 is tightened, allowing the bolt 36 to press and fix the support rod 28 using the friction pad 37. Then, the crosshead 29 and the cross groove 25 can be used to drive the rotating shaft 20 to rotate.

[0036] In a preferred embodiment of the present invention, the push-pull component further includes: The through slot 42 is opened through the rotating cylinder 15 and is located between the two rows of connecting rods 17; The electric actuator 43 is fixed inside the rotary cylinder 15, and its telescopic end is rotatably connected to the lead screw 44; The inclined wheel 45 is fixed to the outside of the lead screw 44 and can be matched with the inclined rubber wheel 50; The connecting plate 46 passes through the slot 42.

[0037] Specifically, the rotary cylinder 15 provides space for the through slot 42, the through slot 42 provides a moving guide for the connecting plate 46, the rotary cylinder 15 provides support for the electric actuator 43, so that the electric actuator 43 can provide support for the lead screw 44, the lead screw 44 can provide threaded support for the connecting plate 46, and can stably support the inclined wheel 45. The inclined wheel 45 can push the lead screw 44 to rotate under the support of the electric actuator 43 under the action of external force, so that the lead screw 44 can use the rotational power and the guiding effect of the through slot 42 to push the connecting plate 46 to translate.

[0038] Wiping components include: The ring 47 is located on the outside of the rotating cylinder 15; The cotton brush 48 is fixed inside the ring 47 and contacts the outer wall of the rotating cylinder 15; The end of the connecting plate 46 is fixedly connected to the inner wall of the ring 47.

[0039] Specifically, the connecting plate 46 can provide support for the ring sleeve 47 under the support of the lead screw 44, and the ring sleeve 47 can provide support for the cotton brush 48. The cotton brush 48 is relatively soft and can be deformed under the action of external force, and will rebound when the external force disappears.

[0040] In practical application, after the acupressure work is completed, the operator can control the electric rod 32 to retract as needed. This causes the electric rod 32 to move the bearing 34 closer to the rotating cylinder 15 via the push plate 31 and bushing 30. Under external force, the bearing 34 then moves the rubber rod 27 closer to the rotating shaft 20. Simultaneously, the rubber rod 27 moves the inclined rubber wheel 50 and the insert plate 53 together, causing the insert plate 53 to be pulled out of the slot 52. At the same time, the inclined rubber wheel 50 contacts the inclined wheel 45. The operator can then start the motor 7, which drives the shaft 26 to rotate via the main gear 5 and the secondary gear 14, allowing the shaft 26 to push against friction. The rotating rubber rod 27 drives the inclined rubber wheel 50 to rotate. The inclined rubber wheel 50, in turn, uses rotational power and friction to drive the inclined wheel 45 to rotate. The inclined wheel 45, in turn, uses rotational power to drive the lead screw 44 to rotate under the support of the electric actuator 43. The lead screw 44, using rotational power and thread action, pushes the connecting plate 46 along the through groove 42 towards the pressure head 16. The connecting plate 46 then drives the ring sleeve 47 to move together. The ring sleeve 47, in turn, drives the cotton brush 48 to move together. During the movement, the cotton brush 48 cleans the soil adhering to the outside of the pressure head 16, preventing the soil adhering to the outside of the pressure head 16 from affecting the pressure pit work in the next construction period.
