Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically to a lightweight, integrated lawnmower. Background Technology

[0002] As a core piece of garden machinery, the structural design of lawnmowers directly affects operating efficiency, maintenance costs, and user experience. Traditional lawnmowers typically employ a C-shaped opening design for their suspension unit. The main body is a single-sided, arc-shaped metal frame (the opening usually faces outwards, resembling a "C"). The closed end is bolted to the top of the hood, while the open end is secured to the operating handle. Furthermore, traditional lawnmowers often use a separate mounting structure for the sliding plates and rollers. This modular design physically separates the functional modules, with the two sliding plates providing support and guidance, and the rollers performing the cutting operation, typically installed independently. While this design facilitates installation, it has the following inherent drawbacks:

[0003] Structural redundancy and excessive weight: The C-shaped opening design requires additional materials, which increases the weight of the entire suspension unit and adds to the cost. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lightweight integrated lawnmower to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lightweight integrated lawnmower includes a hood, a transmission unit, and a mowing unit. A suspension unit is located on the top of the hood and is connected to the hood via a detachable component. The suspension unit includes a left suspension plate, a right suspension plate, an upper left suspension plate, an upper right suspension plate, a lower right suspension plate, an upper left suspension plate, and a lower left suspension plate. The left and right suspension plates are fixed to the ends away from the hood surface via connecting plates. The left and right suspension plates are symmetrically designed; this symmetrical design increases the effective contact area and reduces the average stress area. The upper left suspension plate is connected above the left suspension plate, and the upper right suspension plate is connected to... The upper right and upper left suspension plates are fixed together by horizontally penetrating upper suspension pins. The left suspension plate has a left extension plate at its bottom, and the right suspension plate has a right extension plate at its bottom. The left extension plate is fixed to the lower left suspension plate with bolts, and the right extension plate is fixed to the lower right suspension plate with bolts. Bolting facilitates disassembly and reduces maintenance costs. The stamped plate on the left suspension plate is integrally stamped and fixed to the left suspension plate. The presence of the stamped plate reduces the weight of the suspension unit, and the stamping technology can create reinforcing ribs, giving the suspension system better resistance to deformation. This suspension unit design constitutes a closed structure. This structure is not only stable but also reduces the weight of the suspension unit and the machine body, maintaining good operational performance even under severe vibrations.

[0007] Preferably, a lower suspension pin passes through between the left extension plate and the left lower suspension plate, and a lower suspension pin also passes through between the right extension plate and the right lower suspension plate. A spacer is fitted on the lower suspension pin. The presence of the lower suspension pin can fix the lower suspension plate and reduce the problem of falling off due to bumps. The presence of the spacer can also reduce the wear of parts.

[0008] Preferably, the gearbox is made of aluminum alloy, with a gearbox mounting plate covering the bottom of the gearbox, and the gearbox mounting bracket is also fixed to the side of the gearbox with bolts. The use of aluminum alloy not only has an environmentally friendly effect, but also reduces the weight of the machine body compared to using other metals.

[0009] Preferably, the mowing unit includes a blade roller and several blades, which are fixed to the blade roller by bolts. The use of bolts allows individual blades to be replaced independently without replacing all of them, and can prevent all blades from falling off when they fail.

[0010] Preferably, the bottom of the hood has a scraping assembly, including a scraper blade and a rotatable roller. The scraper blade is connected to the bottom of the hood by a detachable component. The presence of the scraper blade prevents grass clippings from entering the lawnmower and causing possible blockage.

[0011] Preferably, the scraper blade has a left sliding plate and a right sliding plate on both sides, which are connected to the sides of the scraper blade by mounting plates. The two ends of the roller are rotatably fixed to the ends of the left and right sliding plates by left and right seat bearings. The connection between the two sliding plates and the roller forms an integrated roller-sliding plate structure. This structure not only allows for the simultaneous disassembly of the sliding plates and the roller, but also allows for simultaneous adjustment of the mowing height, eliminating the need for individual adjustments that could lead to inconsistent heights between the roller and the sliding plates. This integrated structure also reduces the use of numerous mounting parts, making the entire lawnmower lighter.

[0012] Preferably, the transmission unit is connected to the transmission shaft via a gearbox, and the end of the transmission shaft is connected to a large pulley. The large pulley and the small pulley are driven by a belt on the same horizontal plane. The connection between the transmission shaft and the large and small pulleys optimizes the power transmission path and effectively increases the service life of each component.

[0013] Preferably, a tensioning plate is designed on the upper part of the left side panel of the hood, and this plate has a right-angle turn.

[0014] The design is simple and is used for belt tension adjustment.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The suspension unit has changed from the traditional C-shaped opening structure to a suspension unit that can be easily disassembled and connected. By stamping the plate on the suspension plate and fixing it with bolts, the weight of the machine body is greatly reduced and material costs are saved.

[0017] (2) The integrated design of the slide and roller is different from the traditional separate design. It can adjust the mowing height consistently, and also reduces the use of a large number of installation parts, thus reducing the weight of the machine. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments:

[0030] Example 1:

[0031] like Figure 1 , Figure 2 , Figure 4, Figure 5 and Figure 8 As shown, a lightweight integrated lawnmower includes a hood 1, a transmission unit 9, and a mowing unit 7. A suspension unit 2 is provided on the upper surface of the hood 1, and the suspension unit 2 is connected to the hood 1 by bolts. The suspension unit 2 includes a left suspension plate 201 and a right suspension plate 202, which are symmetrically designed. An upper left suspension plate 203 and an upper right suspension plate 204 extend from the left and right suspension plates 201 and 202, respectively. A left extension plate 214 is located below the left suspension plate 201, and a right extension plate 204 is located below the right suspension plate 202. The right extension plate 215 is fixed to the lower left suspension plate 208 and the lower right suspension plate 209 respectively by bolts. The upper left suspension plate 203 and the upper right suspension plate 204 are fixed by a transversely penetrating upper suspension pin 211. The upper surface of the left suspension plate 201 is provided with a stamping plate 212, a connecting plate mounting hole 213, a hook mounting hole 216, and an upper suspension pin hole 222. The stamping plate 212 is fixed to the left suspension plate 201 by integral stamping. There is a plug welding hole 217 between the upper suspension pin holes 222. The hook 2 is connected to the hook mounting hole 216. 18. The left and right ends of the connecting plate 207 are respectively bolted to the left suspension plate 201 and the right suspension plate 202. When the lawnmower is operating, when the lawnmower travels to uneven ground, the impact force of the ground is transmitted through the mowing unit 7 to the lower left suspension plate 208 and the lower right suspension plate 209. The lower left suspension plate 208 and the lower right suspension plate 209 then transmit the force to the upper left suspension plate 203 and the upper right suspension plate 204. At this time, the presence of the upper left suspension plate 203 and the upper right suspension plate 204 restricts the transition upward movement of the suspension unit 2, while the lower left suspension plate 207... The lower right suspension plate 209 and the lower left suspension plate 201 allow for slight cushioning of the suspension unit 2. The left and right suspension plates 201 and 202, fixed by the connecting plate 207, resist lateral forces. The stamped plates 212 on the left and right suspension plates 201 and 202 enhance their strength, preventing the suspension unit 2 from tilting due to lateral forces, thus avoiding instability in the mowing path. The presence of the plug weld hole 217 also provides strength and stability to the entire suspension unit 2. The lower suspension pin 210 passes through the left extension plate 214 and the lower left suspension plate 208, and also passes through the right extension plate 215 and the lower right suspension plate 209. The lower suspension pin 210 is fitted with a spacer 221, which reduces wear on components. The entire suspension unit 2 not only reduces the weight of the machine body, but the stamped plates 212 and the bolt connections also reduce material costs.

[0032] like Figure 4 and Figure 6As shown, a gearbox 3 is installed on top of the hood 1, and a gearbox mounting plate 301 is located below the gearbox 3. The gearbox mounting plate 301 is fixed to the gearbox 3 with bolts. The gearbox 3 is made of aluminum alloy. A gearbox mounting base 302 is installed on the right side of the gearbox mounting plate 301 and is connected to the gearbox 3 with bolts. There is a grease pipe installation area 4 on the upper left side of the gearbox 3. The grease pipe installation area 4 is equipped with a grease cup 404, a grease pipe 403, and a pipe clamp 402 from top to bottom. When the lawnmower is not started, the gearbox 3 is not rotating. When the lawnmower is started, the grease cup 404 begins to transmit lubricating grease to the gearbox 3 through the grease pipe 403 and the pipe clamp 402. The gearbox 3 then outputs power to the transmission unit 9 according to the needs of the lawnmower. The fact that the gearbox 3 is made of aluminum alloy makes the lawnmower lighter and has a green and environmentally friendly function.

[0033] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the machine cover 1 includes a transmission unit 9 inside. A transmission shaft 907 is connected to the left side of the gearbox 3. The transmission shaft 907 is connected to a vertical expansion sleeve 15. The expansion sleeve 15 is horizontally connected to a large pulley 901. A belt 903 is connected to the lower side of the large pulley 901. The large pulley 901 is connected to a small pulley 902 through the belt 903. A pulley cover 905 is provided outside the large pulley 901. A baffle 12 is fixed to the inner side of the lower part of the machine cover 1 connected to the suspension unit 2. The baffle 12 is vertically connected to the machine cover 1. The lower part of the machine cover 1 also includes a cutter roller 701. The cutter roller 701 includes several blades 702. The bottom of the machine cover 1 The machine has a soil scraping assembly 5, including a scraper blade 501 and a roller 502. The scraper blade 501 is connected to the bottom of the machine cover 1 by a detachable part. The left and right sides of the scraper blade 501 are equipped with a left sliding plate 205 and a right sliding plate 206 by mounting plates 14. The left sliding plate 205 and the right sliding plate 206 fix the roller 502 in the middle by a left belt bearing 219 and a right belt bearing 220. A tensioning plate 13 is also designed on the upper part of the left side plate of the machine cover 1. The plate is a right-angle turn and has a simple design. The tensioning plate 13 maintains appropriate tension by adjusting the length of the belt 903 or the path to ensure transmission efficiency. When the lawnmower starts, the tractor's rear power input shaft transmits power to the gearbox 3 to drive its rotation. The gearbox 3 first outputs power to the small pulley 902, which then transmits the power to the large pulley 901 through friction. The large pulley 901 then transmits the power to the mowing unit 7, causing the cutter roller 701 of the mowing unit 7 to rotate, which in turn drives the blades 702 to cut the weeds. The roller 502, which is fixed to the left sliding plate 205 and the right sliding plate 206, forms an integrated structure that can be raised or lowered simultaneously to adjust the mowing height.
