[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the collection box is used to collect the chopped weeds. The collection box moves with the front through the rear wheels, which improves the movement force of the lawnmower. When the weeds fall into the collection box from the opening, they will first fall into the inclined guide table. The inclined angle further guides the weeds to the collection point of the collection box, avoiding the accumulation of weeds at the opening. Subsequently, the discharge flap can be opened by rotating to take out the weeds inside. In the collection state, the discharge flap is in the closed state and is fixed by the pin on the top to prevent it from opening during the cutting process, thus improving stability. The above structure enables the lawnmower to have a collection function, which makes it convenient for users to collect the cut weeds.

[0015] (2) In this utility model, when the lawn mower moves, the weeds are shredded by the cutting component. The upper arc-shaped limiting plate is located at the top and is used to limit the top of the cutting component. The lower arc-shaped guide plate restricts the space below the cutting component. Its arc structure allows the cutting component to rotate and drive the shredded weeds to the opening, so that the shredded weeds can only move through the opening and fall into the collection component behind, thereby achieving the guiding effect and making it convenient for users to collect the shredded weeds.

[0016] (3) In this utility model, when the user pushes the lawnmower to move, the wheels on both sides rotate under the influence of the thrust. The internal gear ring and the gear mesh with each other, causing the rotating internal gear ring to drive the gear to rotate, thereby causing the rotating rod to rotate. The arc-shaped cutting blade installed on the rotating frame cuts the weeds through the rotational force. The arc-shaped cutting blade adopts an arc structure, which has a better cutting effect. It is also arranged in a ring-shaped interval to make its cutting area larger and improve the cutting effect. The above structure can realize the displacement of the lawnmower and the rotation of the cutting components by pushing, which reduces energy consumption and cost and improves practicality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4An embodiment of this utility model provides a push assembly for a hand-push lawnmower, comprising: an assembly frame 1, wheels 2 mounted on both sides of the assembly frame 1, a cutting assembly 3 mounted between the two assembly frames 1, guide assemblies 4 mounted at both ends of the cutting assembly 3, a material collection assembly 5 mounted behind the guide assemblies 4, and a gripping assembly 6 mounted above the material collection assembly 5. An internal gear ring 201 is mounted on the inner wall of the wheels 2. The cutting assembly 3 includes a rotating rod 301, gears 304 mounted on the outer walls at both ends of the rotating rod 301, the gears 304 meshing with the internal gear ring 201, two sets of rotating frames 302 symmetrically mounted on the outer wall of the rotating rod 301, and multiple arc-shaped cutting blades 303 mounted between the two sets of rotating frames 302, the multiple arc-shaped cutting blades 303 being distributed in a ring-like interval.

[0024] When the user pushes the lawnmower to move, the wheels 2 on both sides rotate under the influence of the thrust. The internal gear ring 201 meshes with the gear 304, causing the rotating internal gear ring 201 to drive the gear 304 to rotate, thereby causing the rotating rod 301 to rotate. The arc-shaped cutting blade 303 installed on the rotating frame 302 cuts the weeds through the rotational force. The arc-shaped cutting blade 303 adopts an arc-shaped structure, which has a better cutting effect. It is also arranged in a ring-shaped interval to make its cutting area larger and improve the cutting effect. The above structure can realize the displacement of the lawnmower and the rotation of the cutting component 3 by pushing, which reduces energy consumption and improves practicality.

[0025] Please see Figure 2 The guide assembly 4 includes a lower arc-shaped guide plate 401 and an upper arc-shaped limiting plate 402. The upper arc-shaped limiting plate 402 and the lower arc-shaped guide plate 401 are respectively installed above and below the cutting assembly 3. An opening 403 for the grass to be discharged is reserved between the upper arc-shaped limiting plate 402 and the lower arc-shaped guide plate 401.

[0026] As the lawnmower moves, the weeds are shredded by the cutting component 3. The upper arc-shaped limiting plate 402 is located at the top and is used to limit the top of the cutting component 3. The lower arc-shaped guide plate 401 restricts the space below the cutting component 3. Its arc-shaped structure allows the cutting component 3 to carry the shredded weeds to the opening 403 during rotation, so that the shredded weeds can only move through the opening 403 and fall into the collection component 5 behind, thereby achieving a guiding effect and making it convenient for users to collect the shredded weeds.

[0027] Please see Figure 2 The material collection assembly 5 includes a material collection box 501. Rear wheels 502 are installed on both sides of the material collection box 501. An inclined guide platform 503 is installed at the front of the material collection box 501 near the guide assembly 4. A discharge flap 504 is movably installed on the rear end face of the material collection box 501 via a hinge. A pin 505 is installed on the top of the discharge flap 504.

[0028] The collection box 501 is used to collect chopped weeds. The collection box 501 moves with the front via the rear wheels 502, improving the movement of the lawnmower. When the weeds fall into the collection box 501 from the opening 403, they first fall onto the inclined guide table 503. The inclined angle further guides the weeds to the collection point of the collection box 501, preventing the weeds from accumulating at the opening 403. Subsequently, the discharge flap 504 can be opened by rotating it to remove the weeds inside. In the collection state, the discharge flap 504 is in a closed state and is fixed at the top by a pin 505 to prevent it from opening during the mowing process, thus improving stability. The above structure enables the lawnmower to have a collection function, making it convenient for users to collect the cut weeds.

[0029] Please see Figure 2 The gripping assembly 6 includes fittings 603 mounted on the outer walls of both sides of the assembly frame 1. Each fitting 603 has a bracket 601 mounted on its outer wall. A handle 602 is mounted on one end of the bracket 601. A connecting rod 604 is mounted between the fittings 603.

[0030] The bracket 601 is installed on the assembly frame 1 via the fitting 603. The two fittings 603 are connected by the connecting rod 604 to improve stability. The user grips the handle 602 at the end of the bracket 601, which makes it easy for the user to apply force and push the lawnmower to move and mow the grass.
