Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1: Please refer to Figures 1 to 4 A fertilizer spreader with adjustable handrail height comprises: a chassis 1, a fertilizer spreader body 12 is installed on the upper end of the chassis 1, a handrail 11 is installed on the right side of the upper end of the chassis 1, a pair of driving wheels are rotatably installed on the left side of the lower end of the chassis 1, and a pair of driven wheels 4 are installed on the left side of the lower end of the chassis 1 through an adjusting mechanism 2; the adjusting mechanism 2 comprises a crossbeam assembly installed on the lower end of the chassis 1, a liftable adjusting assembly is installed in the crossbeam assembly, a wheel frame 3 is installed at the lower end of the adjusting assembly, and a driven wheel 4 is rotatably installed in the wheel frame 3.

[0030] The working principle of the utility model is as follows: by adjusting the height of the adjusting assembly in the crossbeam assembly, the support height of the driven wheel 4 can be adjusted, and then the tilting height adjustment of the free end of the armrest 11 can be achieved. The free end of the armrest 11 can be adjusted to a suitable height according to the height of the operator, thereby making it convenient for the operator to use the fertilizer spreader and better meeting the use requirements.

[0031] As a further solution, the beam assembly includes an adjusting beam 21 installed at the right side of the lower end of the chassis 1, and adjusting sleeves 22 are fixed on the front and rear sides of the adjusting beam 21, and the adjusting sleeve 22 is a threaded sleeve; the adjusting assembly includes an adjusting rod 23 threadedly screwed in the adjusting sleeve 22, an auxiliary rod 24 extends from the upper end of the adjusting rod 23, and a horizontally arranged auxiliary jack 241 is provided on the auxiliary rod 24, and the adjusting rod 23 is a threaded rod, and the external thread of the adjusting rod 23 is adapted to the internal thread of the adjusting sleeve 22.

[0032] The working principle of the adjustment mechanism is: when the height of the handrail 12 needs to be adjusted, the auxiliary rod 24 is rotated to drive the adjustment rod 23 threadedly mounted in the adjustment sleeve 22 to rotate, and by driving the adjustment rod 23 to rotate forward, the adjustment rod 23 can be driven to move upward, thereby causing the driven wheel 4 to move up, thereby reducing the distance between the handrail 12 and the ground; by driving the adjustment rod 23 to rotate reversely, the adjustment rod 23 can be driven to move downward, thereby causing the driven wheel 4 to move downward, thereby increasing the distance between the handrail 12 and the ground, making it convenient for people of different heights to use the fertilizer spreader.

[0033] Specifically, the present embodiment also includes a crank assembly, which includes a crank portion 51 and a swing arm 5, one end of the swing arm 5 is rotatably connected to the crank portion 51, the other end of the swing arm 5 is sleeved on the auxiliary rod 24, and the other end of the swing arm 5 has a swing arm socket 52 that cooperates with the auxiliary socket 241, and the auxiliary socket 241 and the swing arm socket 52 are fixed by an inserted pin shaft.

[0034] By shaking the crank assembly, it is easier to drive the auxiliary rod 24 and the adjusting rod 23 to rotate, thereby adjusting the supporting height of the driven wheel 4.

[0035] As a further solution, the wheel frame 3 includes a top plate 31, and side plates 32 are installed on both sides of the lower end of the top plate 31. The driven wheel 4 is rotatably installed between the side plates 32 through a rotating shaft. A connecting seat 33 is fixedly installed at the lower end of the adjusting rod 23, and the top plate 31 is rotatably installed on the connecting seat 33; the side plates 32 are arc-shaped. By setting the arc-shaped side plates 32, the carrying capacity of the fertilizer spreader can be effectively improved, and the stability of the movement of the fertilizer spreader can be improved. At the same time, it is also beneficial to the universal rotation of the top plate 31 relative to the adjusting rod 23, which can improve the maneuverability of the fertilizer spreader and facilitate the control of the direction of the driven wheel.

[0036] Example 2: Please refer to Figures 5 to 9 A fertilizer spreader with adjustable handrail height comprises: a chassis 1, a fertilizer spreader body 12 is installed on the upper end of the chassis 1, a handrail 11 is installed on the right side of the upper end of the chassis 1, a pair of driving wheels are rotatably installed on the left side of the lower end of the chassis 1, and a pair of driven wheels 4 are installed on the left side of the lower end of the chassis 1 through an adjusting mechanism 2; the adjusting mechanism 2 comprises a crossbeam assembly installed on the lower end of the chassis 1, a liftable adjusting assembly is installed in the crossbeam assembly, a wheel frame 3 is installed at the lower end of the adjusting assembly, and a driven wheel 4 is rotatably installed in the wheel frame 3.

[0037] The crossbeam assembly includes an adjusting crossbeam 21 installed at the right side of the lower end of the chassis 1 , and adjusting sleeves 22 are fixed to both the front and rear sides of the adjusting crossbeam 21 .

[0038] The difference from the first embodiment is that the adjustment assembly comprises a threaded rod 25, an auxiliary rod 24 extends from the upper end of the threaded rod 25, a horizontal auxiliary plug hole 241 is provided on the auxiliary rod 24, and a step portion 26 is formed at the connection between the auxiliary rod 24 and the threaded rod 25;

[0039] The adjusting sleeve 22 is a hollow sleeve, and the upper end of the adjusting sleeve 22 has a small plug hole 27 that is movably inserted into the auxiliary rod 24;

[0040] The wheel frame 3 includes a top plate 31, and side plates 32 are installed on both the front and rear sides of the lower end of the top plate 31. A driven wheel 4 is rotatably installed between the side plates 32 via a rotating shaft. A threaded sleeve 311 is also fixedly installed on the top plate 31. The upper end of the threaded sleeve 311 is movably inserted into the adjusting sleeve 22, and the threaded rod 25 is screwed into the threaded sleeve through threads.

[0041] In this embodiment, the support height of the driven wheel 4 is adjusted by the threaded cooperation between the threaded rod 25 and the threaded sleeve 311. After the assembly is completed, the adjusting sleeve 22 guides the threaded sleeve 311, and the step portion 26 abuts against the lower end surface of the small socket 27 at the upper end of the adjusting sleeve 22. The universal rotation of the lower driven wheel 4 is achieved through the cooperation between the auxiliary rod 24 and the small socket 27. Compared with the embodiment 1, the assembly is more convenient.
