[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] like Figure 1-Figure 2 As shown, this embodiment provides a supporting roller mechanism, including a column 1, an axle seat 2 and an adjusting pin 6, the column 1 is vertically arranged and has a plurality of horizontally penetrating through holes, the plurality of through holes are parallel to each other and spaced apart up and down, the axle seat 2 is fixedly arranged and slidably sleeved outside the column 1, the axle seat 2 has a socket, one end of the adjusting pin 6 passes through the socket and extends into any one of the through holes.

[0029] The utility model realizes multi-level adjustable height of the lawn mower through reasonable structural design, has a simple structure and is easy to adjust, so that the height of the lawn mower can adapt to various working environments and working requirements, thereby improving the mowing efficiency.

[0030] The supporting roller mechanism plays a role in supporting the entire lawn mower. The shaft seat 2 is fixedly connected to the lawn mower frame. The column 1 passes through the shaft seat 2 to play a supporting role. A row of through holes is opened on the column 1. When the adjustment pin 6 is pulled out of the through hole on the column 1 (such as Figure 2 As shown), the column 1 can move up and down to adjust the height of the lawn mower. When the adjustment pin 6 is inserted into one of the through holes (as shown in FIG. Figure 1 As shown), the upright post 1 is fixed, the height of the lawn mower is determined, and normal mowing operations can be performed.

[0031] The number of through holes can be designed according to actual usage, and the spacing distance also depends on the situation.

[0032] On the basis of the above technical solution, the shaft seat 2 includes a vertically arranged sleeve and a horizontally arranged connecting cylinder, one end of the connecting cylinder is fixedly connected to the sleeve, the adjusting pin 6 is located in the connecting cylinder, and the jack is provided at a position of the sleeve corresponding to the connection with the connecting cylinder. The vertical sleeve is passed through by the column 1, and the horizontal connecting cylinder is used to set the adjusting pin 6. At least one of the sleeve and the connecting cylinder is fixedly connected to the frame of the mower. Such a structure is stable and firm, and the operation of inserting and removing the adjusting pin 6 is easier to achieve.

[0033] Specifically, a baffle is provided at the other end of the connecting tube, and the other end of the adjusting pin 6 passes through the baffle. The sleeve can be designed as a cylindrical tube, the connecting tube can be designed as a cylindrical tube or a truncated cone tube, and a hole corresponding to the adjusting pin 6 and passing through the adjusting pin 6 can be provided on the baffle at the other end of the connecting tube, so that the adjusting pin 6 can be limited so that it can be accurately inserted into the connecting tube and the through hole.

[0034] More specifically, the supporting roller mechanism further includes a spring 3, the spring 3 is sleeved outside the adjusting pin 6, and the two ends of the spring 3 are respectively connected to the baffle plate and the other end of the adjusting pin 6. One end of the spring 3 needs to be fixedly connected to the other end of the adjusting pin 6, and the other end abuts or is fixedly connected to the baffle plate, and the spring 3 is in a natural state or a stretched state, generating an elastic force to push the adjusting pin 6 horizontally toward the column. When there is no external force, the spring pushes the adjusting pin into the through hole to fix the column, such as Figure 1 As shown. When a reverse external force is applied to the adjustment pin 6 (the adjustment pin 6 can be directly pulled by manpower), the spring 3 is further stretched, the adjustment pin 6 withdraws from the through hole, and the column 1 can move up and down to adjust the height of the lawn mower. When the adjustment is in place, the reverse external force applied to the adjustment pin 6 is cancelled (the adjustment pin 6 is released), the spring 3 is reset, and the adjustment pin 6 is pushed into the through hole again to fix the column 1. The use of the spring 3 can realize the automatic reset of the adjustment pin 6, the locking and release of the column 1 are clearer, the overall structure is stable, and the reliability is better.

[0035] Preferably, the supporting roller mechanism further comprises an adjustment handle 4, and the adjustment handle 4 is connected to the other end of the adjustment pin 6. The adjustment handle 4 is convenient for applying a force to the adjustment pin.

[0036] One implementation is that the adjustment handle 4 is fixedly connected to the other end of the adjustment pin 6, and the reverse external force is applied to or removed from the adjustment pin 6 by a person directly pulling the adjustment handle 4 outward or releasing the adjustment handle 4. In this solution, the adjustment handle 4 can be a structure that is easy for a person to hold, such as a round handle, an L-shaped pull rod, etc.

[0037] In addition, another implementation scheme is that the adjustment handle 4 is rotatably connected to the other end of the adjustment pin 6, and it can be rotated until one end abuts against the baffle. The other end of the adjustment pin 6 is fixedly connected to a rotating shaft, and the adjustment handle 4 is rotatably connected to the rotating shaft. When a reverse external force is applied to the adjustment pin 6, one end of the adjustment handle 4 can be rotated to abut against the baffle by rotating. Through structural design, the spring 3 can be kept in a further stretched state, and the adjustment pin 6 can be kept in a state of exiting the through hole. In this way, when adjusting the height of the column 1, it is not necessary to apply a reverse external force for a long time, which can free up manpower and can easily adjust the height of the column 1. While saving labor, it is more convenient to adjust the height of the column 1. In this solution, the adjustment handle 4 can be a two-section structure, one section is a U-shaped structure, which is rotatably connected to the rotating shaft inside, and can be rotated without affecting the installation and function realization of the spring 3, and the other section is a structure that is easy for people to hold. When the lock state is in a locked state, the adjustment handle 4 is set vertically. When it is necessary to adjust the height of the column 1, the person holds the other section of the adjustment handle 4, flips it 90°, and rotates the adjustment handle 4 to a horizontal state. The end face of one section corresponds to the baffle. After the person releases the adjustment handle 4, under the action of the elastic force of the spring 3, the end face of one section of the adjustment handle 4 is against the baffle.

[0038] Preferably, one end of the adjustment handle 4 is arranged to have an arc transition near the shaft seat 2. One end of the adjustment handle 4 is a plane that can abut against the baffle plate, and in the process of rotating the adjustment handle 4, in order to avoid collision and damage between the adjustment handle 4 and the baffle plate and the shaft seat 2, the position that is prone to collision can be designed as an arc surface structure for smooth transition.

[0039] On the basis of the above technical solution, the supporting roller mechanism also includes a fixing pin 5, and the fixing pin 5 is inserted into one of the through holes above the shaft seat 2. A roller will be installed below the column 1, so the column 1 will not usually fall out of the shaft seat 2 upwards, but there is usually no other structure above the column 1. When adjusting the height of the column 1, if you are not careful, the column 1 may fall out of the shaft seat downwards, and there is a risk of damage to the lawn mower. Based on this, a fixing pin 5 can be added above the shaft seat 2 to fix and prevent the column 1 from falling off the shaft seat 2. Of course, it is also possible to set another fixing pin 5 in one of the through holes below the shaft seat 2, so that the column 1 and the shaft seat 2 can be limited together from top to bottom, which is more secure.

[0040] Specifically, the fixing pin 5 can be composed of a middle pin body and fixed structures at both ends. The pin body is inserted into the through hole, and the fixed structures at both ends fix the pin body. The fixed structures at both ends are preferably a long strip structure with one end fixedly connected to one end of the pin body and the other end detachably connected to the other end of the pin body. The detachable connection method is plug-in, hooking, telescopic ring, etc.

[0041] This embodiment also provides a lawn mower, comprising a frame and a plurality of the supporting roller mechanisms, wherein the shaft seat 2 of each supporting roller mechanism is fixedly connected to the frame, and a roller is installed at the lower end of the column 1 of each supporting roller mechanism. The roller is rotatably installed at the lower end of the column 1 through the mounting frame, so that the lawn mower can be moved by a tractor.

[0042] Optionally, the lawn mower of this embodiment can be any kind of lawn mower that can be mounted on a tractor, and can be front-mounted, rear-mounted or mid-mounted, and is particularly suitable for a mid-mounted lawn mower for a tractor.

[0043] Optionally, there are four supporting roller mechanisms and four corresponding rollers.
