Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural machinery, in particular to a mower. BACKGROUND

[0002] The mower plays a very key role in many fields such as garden maintenance and lawn trimming, and its grass discharging system is directly related to the efficiency and quality of the mowing operation.

[0003] The traditional mower has obvious defects in the design of the grass discharging port. Due to the lack of fine optimization of the structure of the grass discharging port, the inner wall corner is usually in a right angle shape or a rough form without special treatment. When the mowing operation continues, a large amount of cut grass needs to be discharged from the body through the grass discharging port. However, the sharp corners and the not smooth inner wall surface cause the grass to encounter a large frictional resistance during the process of passing through the grass discharging port. This friction not only slows down the discharge speed of the grass, but also easily causes the grass to accumulate at the grass discharging port. As the mowing operation progresses, the amount of accumulated grass increases, gradually forming a clogging condition. Once the grass discharging port is clogged, the subsequent cut grass cannot be smoothly discharged, and the grass accumulation in the mower becomes more and more serious, thereby greatly reducing the mowing efficiency of the mower. The operator has to frequently stop and clean the grass discharging port, which not only consumes a lot of time and manpower, increases the complexity and cost of equipment maintenance, but also seriously interferes with the continuity and smoothness of the mowing operation, cannot meet the modern lawn maintenance requirements of high efficiency and convenience, and greatly limits the working efficiency and user experience of the mower in actual application scenarios.

[0033] In a preferred embodiment, referring to Figures 1 to 3The application provides a mower 1, comprising: a mower body 10, the mower body 10 is provided with a mowing chassis 20 and a grass discharge port 30, the grass discharge port 30 is communicated with the mowing chassis 20, and the inner wall corner of the grass discharge port 30 is chamfered 31.

[0034] The chamfering 31 of the grass discharge port 30 position makes the grass discharge port 30 position more rounded, the smooth chamfered 31 surface of the grass discharge port 30 is easier to clean, can effectively reduce the frictional resistance, reduces the accumulation of grass after the grass passes through the grass discharge port 30, so that the grass is more smooth when passing through the grass discharge port 30, reduces the difficulty of cleaning the grass at the grass discharge port 30 position, and effectively improves the weeding efficiency of the mower 1, preferably, the inner diameter of the chamfer 31 is arranged in the range of 10 to 50 mm, so as to ensure the grass discharge efficiency of the grass at the grass discharge port 30.

[0035] Meanwhile, the transition piece 40 can further optimize the grass conveying channel between the mowing chassis 20 and the grass discharge port 30, and the grass in the mowing chassis 20 can more easily reach the grass discharge port 30 through the guidance of the transition piece 40.

[0036] As a preferred, at one end of the transition piece 40 close to the grass discharge port 30, the edges of the flow guide surface of the transition piece 40 are arc-shaped 44, so that the transition piece 40 is smoothly connected with the chamfer 31 of the grass discharge port 30, which can effectively prevent the grass from being blocked when passing through the transition piece 40, so as to further improve the weeding efficiency of the mower 1.

[0037] As another preferred, referring to Figures 4 to 5 From one end of the transition piece 40 close to the mowing chassis 20 to one end close to the grass discharge port 30, the flow guide surface is gradually inclined and rises, which further guides the grass and improves the smoothness of the grass at the grass discharge port 30. Preferably, the inclination angle of the flow guide surface of the transition piece 40 is preferably in the range of 10 to 40 degrees, so as to reduce the climbing difficulty of the grass on the flow guide surface on the premise that the flow guide surface of the transition piece 40 plays a certain flow guiding role.

[0038] Further preferably, the transition piece 40 is provided with an end connecting assembly 41 and a side connecting assembly 42, and the transition piece 40 is detachably connected with the mower main body 10 through the end connecting assembly 41 cooperating with the side connecting assembly 42; wherein the end connecting assembly 41 is connected with the grass discharging port 30, and the grass discharging port 30 is provided with a recess 32 connected with the end connecting assembly 41, which is a containing groove structure capable of containing the upper fixing block 411, so that the upper surface of the upper fixing block 411 is flush with the surface of the grass discharging port 30, reducing the grass blockage. The detachable connection of the transition piece 40 with the mower main body 10 facilitates the maintenance and cleaning of the transition piece 40, and facilitates the separate adjustment of the transition piece 40 during the mold casting process, thereby reducing the trial and error cost.

[0039] Preferably, the end connecting assembly 41 comprises an upper fixing block 411 and a lower fixing block 412, which are fixedly clamped to the edge of the grass discharging port 30 through the cooperation of the upper fixing block 411 and the lower fixing block 412, thereby improving the connection stability and strength, and limiting the movement of the transition piece 40 in the vertical direction. The side connecting assembly 42 comprises a bending portion 421 and a fixing hole 422, the bending portion 421 is buckled to the mower main body 10 to improve the connection stability, and the fixing hole 422 is sleeved with the mower main body 10 to fix the position of the transition piece 40, thereby limiting the movement of the transition piece 40 in the horizontal direction, and improving the stability of the transition piece 40 after being assembled to the mower main body 10, thereby avoiding the shaking of the transition piece 40.

[0040] Preferably, a plurality of first reinforcing ribs 43 are further provided on the transition piece 40 in a spaced manner, and the first reinforcing ribs are arranged on the back of the flow guide surface, which can improve the support strength of the flow guide surface to a certain extent, and the reinforcing ribs arranged in a spaced manner can have a relatively optimal structural strength while ensuring the lightweight of the transition piece 40.

[0041] Further, referring to Figure 2 and Figure 3 , the distance from the bottom surface of the grass discharging port 30 to the bottom surface of the mower main body 10 is recorded as the first length X1, and the value of the first length X1 is preferably between 20 to 70 mm, so as to avoid the grass discharging port 30 being arranged too low or too high to affect the grass discharging efficiency. Correspondingly, the front end of the transition piece 40 close to the mower chassis 20 has a certain guide protrusion, and the height of the guide protrusion is recorded as the second length X2, and the value of the second length X2 is preferably between 10 to 70 mm, and the guide protrusion with a certain height can stop the grass from separating from the mower chassis 20 at the bottom position of the transition piece 40, while it is necessary to avoid the second length X2 being too large, and the guide protrusion with a too large second length X2 will affect the grass guiding effect of the transition piece 40.

[0042] Preferably, referring to Figure 3 , Figures 6 to 7The cutting blade 21 is provided in the cutting chassis 20 and includes a blade body 211 and blade ears 212 extending from both sides of the blade body 211.

[0043] It should be noted that, referring to Figure 6 The extension end of the blade ear 212 is parallel to the side end of the blade body 211, and the front end is curved upward. The cutting edge 214 is located on the opposite side of the blade ear 212. The blade ear 212 in the present application does not exceed the edge of the blade body 211, and thus the blade ear 212 in the present application can effectively assist the cutting edge 214 in cutting work. When facing thicker or harder grass stems, the blade ear 212 can serve as an extension of the cutting edge 214, greatly expanding the cutting range and making the cutting work more smoothly, thereby significantly improving the cutting efficiency. At the same time, in the design of the cutting blade 21 involved in the present application, the blade ear 212 also has the advantage of facilitating the removal of grass. During the cutting process, the blade ear 212 can guide the grass in a certain direction, avoiding the accumulation of grass around the blade body 211, further ensuring the smoothness and efficiency of the cutting work, reducing the problem of jamming caused by grass accumulation, and improving the overall performance and practicality of the cutting blade 21.

[0044] Preferably, the surface of the blade body 211 is provided with a second reinforcing rib 213. Specifically, the second reinforcing rib 213 is a hexagonal structure and is arranged in a ring shape on the blade body 211 to effectively improve the strength of the cutting blade 21 and prevent the cutting blade 21 from cracking due to insufficient strength at a certain point during high-speed rotation.

[0045] Preferably, referring to Figure 8 The cutting machine 1 further comprises a grass combing block 50 connected to the cutting machine body 10 in a detachable manner for easy replacement of the grass combing block 50. The front end of the grass combing block 50 is provided with a tooth-like structure 51 arranged at a first interval 52.

[0046] The grass combing block 50 can comb the fallen grass stems to stand up, help the mower 1 pass through the lawn more smoothly when mowing, so as to better complete the cutting work and make the lawn more neat and beautiful. If the grass combing block 50 is not provided, the fallen grass will make the lawn look messy and affect the overall landscape effect. At the same time, for the lawn with more lush growth, the grass combing block 50 can help separate the intertwined grass leaves, so that each grass can fully receive sunlight and air, promoting the healthy growth of the lawn. With the passage of time, a layer of dead grass will accumulate on the lawn, and the grass combing block 50 can effectively remove this layer of dead grass to prevent the dead grass layer from being too thick to affect the growth of new grass. The dead grass layer that is too thick will hinder the penetration of water and nutrients, and is also prone to breeding diseases and pests.

[0047] At the same time, the toothed structure 51 of the grass combing block 50 can be inserted deeper into the lawn to better lift and comb the fallen grass stems and dead grass. Compared with a smooth structure, the toothed structure 51 has a larger contact area and can interact with the grass more effectively, and the toothed structure 51 is also not easy to deform or damage, prolonging the service life of the mower 1.

[0048] Further preferably, the bottom of the grass combing block 50 has an air inlet 53 communicating with the mowing deck 20, and the size of the air inlet 53 is matched with the size of the first interval 52. The air inlet 53 is provided to improve the air intake amount when the mower 1 works at a low gear, and is matched with the structure of the grass discharge port 30 in the present application to improve the grass collection rate. At the same time, the first interval 52 is preferably between 5 to 20 mm. Under the premise that the toothed structure 51 with this setting interval has the effect of combing the fallen grass stems to stand up, the size of the first interval 52 is matched with the air intake amount of the air inlet 53 to meet the air intake requirement of the mower 1 when working at a low gear.

[0049] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application.
