Description

Technical Field

[0001] The utility model relates to the field of lawn mowers, in particular to a central lawn mower housing and a lawn mower. Background Art

[0002] Currently, the lawn mower of a tractor is usually mounted on the front or rear end of the tractor. There is no mid-mounted lawn mower. A mid-mounted lawn mower is a lawn mower mounted under the tractor between the two wheels.

[0003] When the mid-mounted lawn mower is coupled to the tractor, the lawn mower is placed flat on the ground, and the front wheels of the tractor pass over the housing of the lawn mower and continue to move forward for a distance. This coupling method requires high structural strength of the housing of the mid-mounted lawn mower. How to improve the structural strength of the housing of the mid-mounted lawn mower without increasing the weight of the lawn mower too much is a problem that technicians in this field need to solve urgently. Utility Model Content

[0004] The technical problem to be solved by the utility model is how to improve the structural strength of the housing of a center-mounted lawn mower.

[0005] The utility model solves the above-mentioned technical problem through the following technical solution: a mid-mounted lawn mower housing, comprising a cover body and an upper support plate, wherein the upper support plates are two and fixed to the top surface of the cover body at intervals, and each upper support plate has an upwardly protruding support section in the middle.

[0006] The utility model has the beneficial effects that two upper support plates are installed on the top surface of the housing body to support the two front wheels of the tractor, protect the housing body when the tractor passes over the housing body, and increase the support strength of the housing body. The upper support plates have a simple structure and will not increase the weight of the lawn mower too much.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the boarding support plate is a strip-shaped plate, the boarding support plate is arranged along the front-to-back direction, and the front and rear ends of the boarding support plate are fixedly connected to the cover shell body.

[0009] The beneficial effect of adopting the above further solution is that the vehicle support plate has a simple structure and light weight.

[0010] Furthermore, it also includes a get-off plate, wherein there are two get-off plates, and the two get-off plates are fixed to the front end wall of the cover shell body at intervals, and the two get-off plates correspond to the two boarding support plates one by one in front and back.

[0011] The beneficial effect of adopting the above further solution is that when the front wheels of the tractor drive the lawn mower down, the lower plate provides a step for the tractor to play a buffering role.

[0012] Furthermore, the included angle a between the lower plate and the front end wall of the cover shell body is greater than 90°, and the lower plate is tilted upward relative to the front end wall of the cover shell body.

[0013] The beneficial effect of adopting the above further solution is that the lower plate is slightly tilted upwards, and when the front wheel of the tractor passes over, even if the lower plate is pressed slightly downwards, it can still have an effective buffering effect.

[0014] Furthermore, the getting off board includes a getting off board main body and a getting off board connecting section, the rear end of the getting off board main body is fixedly connected to the getting off board connecting section, the getting off board connecting section is fixedly connected to the front end wall of the cover shell main body, and the angle a between the getting off board main body and the front end wall of the cover shell main body is greater than 90°.

[0015] The beneficial effect of adopting the above further solution is that the rear end of the lower plate body is connected to the lower plate connecting section, and is fixed to the cover body through the lower plate connecting section. The lower plate body and the lower plate connecting section form an approximately L-shaped plate with high structural strength.

[0016] Furthermore, the rear side of the top surface of the housing body is recessed downward to form a recessed portion.

[0017] The beneficial effect of adopting the above further scheme is that the top of the housing body of this scheme is high in front and low in the back, forming a step shape, the transmission structure can be installed in the concave part, and the thickness of the rear side of the housing body is reduced as a whole. When the mower is raised to the highest position (when cutting higher grass or the unit is transferred), the rear part of the housing body can effectively avoid the tractor transmission shaft, so that the mower can be raised higher and adapted to cutting higher grass. And because the bottom of the mower is higher from the ground, the unit has better passability.

[0018] Furthermore, it also includes a transmission shield, which is fixedly connected to the top surface of the housing body.

[0019] The beneficial effect of adopting the above further scheme is that the transmission shield is connected to the cover body and covers the outside of the transmission structure, which can protect the transmission structure installed on the cover body and has the functions and advantages of safety and noise elimination.

[0020] Furthermore, it also includes a mower blade guard, which is fixedly connected to the bottom surface of the cover shell body. The mower blade guard is cylindrical, and its diameter gradually decreases from top to bottom.

[0021] The beneficial effect of adopting the above further scheme is: the mower blade guard is used to protect the rotating shaft of the mower blade. The mower blade guard is wide at the top and narrow at the bottom, and has smooth sides. It can effectively block grass clippings from moving upward and thus moving toward the grass discharge port of the mower, making it convenient for the mower to discharge grass after mowing without squeezing the grass.

[0022] Furthermore, the side wall of the lawn mower blade guard is a concave arc surface.

[0023] The beneficial effect of adopting the above further solution is that the side wall of the mower blade guard is an inwardly concave arc surface, which guides the grass smoothly and discharges the grass smoothly.

[0024] The utility model also provides a lawn mower, comprising the central lawn mower housing.

[0025] The beneficial effects are: the cover body has high supporting strength and simple structure, and the load on the tractor will not be increased too much while the structural strength is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] It should be noted that Figure 4The dot-dash line is used to briefly represent the cover body, which is only used to illustrate the installation angle of the lower plate. The size relationship between the lower plate and the cover body in the figure does not represent the actual size relationship between the two.

[0036] like Figure 1-Figure 6 As shown, this embodiment provides a mid-mounted lawn mower housing, including a cover body 1 and an upper support plate 2, wherein the upper support plates 2 are two, and the two upper support plates 2 are fixed at intervals on the top surface of the cover body 1, and each of the upper support plates 2 has an upwardly protruding support section 21 in the middle.

[0037] Two upper support plates 2 are mounted on the top surface of the housing body 1 to support the two front wheels of the tractor, protect the housing body 1 when the tractor passes over the housing body 1, and increase the support strength of the housing body 1. The upper support plates 2 have a simple structure and will not increase the weight of the lawn mower too much.

[0038] Specifically, Figure 2 As shown, the support section 21 in the middle of the boarding support plate 2 is flat, and the two ends of the boarding support plate 2 and the support section 21 are transitioned through an inclined plane, and the boarding support plate 2 and the side of the housing body 1 are approximately trapezoidal in shape. Alternatively, the support section 21 is an arc-shaped plate.

[0039] Specifically, the support section 21 is parallel to the top surface of the housing body 1 .

[0040] Specifically, the distance between the two upper vehicle support plates 2 is equal to the left and right wheel tracks of a common type of tractor.

[0041] On the basis of any of the above schemes, the boarding support plate 2 is a strip-shaped plate, the boarding support plate 2 is arranged along the front-to-back direction, and the front and rear ends of the boarding support plate 2 are fixedly connected to the cover body 1.

[0042] The vehicle boarding support plate 2 has a simple structure and is light in weight.

[0043] Based on any of the above schemes, the mid-mounted lawn mower shell also includes a lower plate 3, and the lower plates 3 are two. The two lower plates 3 are fixed at intervals on the front end wall of the cover body 1, and the two lower plates 3 correspond to the two upper support plates 2 one by one front to back.

[0044] The lower plate 3 provides a step for the tractor when the front wheels of the tractor drive the lawn mower down, thus playing a buffering role.

[0045] Specifically, the width of the lower vehicle plate 3 is greater than the width of the upper vehicle support plate 2 .

[0046] like Figure 1 As shown, the left and right sides of the front end surface of the cover body 1 are inclined backward, and the front end surface of the lower plate 3 is arranged along the left and right directions.
