Description

Technical Field

[0001] This utility model relates to the field of skid steer loader accessories, specifically a roller cutter. Background Technology

[0002] A skid steer loader is a wheeled, specialized chassis-based machine that uses the difference in linear speed between the wheels on both sides to achieve vehicle steering. It employs a wheeled running gear, all-wheel drive, and skid steering, allowing for rapid and random changes or attachment of various work attachments on-site to adapt to different working environments and tasks.

[0003] In large open areas, lawnmowers are often mounted on skid steer loaders to improve lawn mowing efficiency. Currently, commonly used lawnmowers for skid steer loaders typically include a mounting bracket for connection to the skid steer loader, a support frame fixed to the mounting bracket, a rotating shaft mounted on the support frame, a blade plate fixed to the shaft, and a power mechanism driving the shaft's rotation. The blade plate is usually a long strip shape and is welded to the outer periphery of the shaft along its axial direction. The power mechanism drives the blade plate to rotate via the shaft to perform the mowing operation. However, since the blade plate is a single piece and welded to the shaft, damage to any part of the blade plate requires replacement of the entire blade plate. This replacement process often involves gas cutting and welding, which is cumbersome and increases operating costs. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary blade lawnmower to solve the problems of current lawnmowers having difficult blade repair and replacement and high operating costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary blade mower, comprising a mounting frame for assembly and connection with a skid steer loader and a support frame fixed to the front of the mounting frame; the rotating shaft includes a crossbeam with both ends rotatably mounted on the bottom two side walls of the support frame and a pair of support plates fixedly mounted on the crossbeams; a plurality of blades are evenly arranged circumferentially around the periphery of the pair of support plates, and both ends of the blades are detachably fixedly connected to the outer edge of the corresponding support plate; a driving assembly is located on one side of the support frame and is used to drive the crossbeams to rotate; and the skid shoes are detachably fixed to the bottom ends of the two side walls of the support frame.

[0006] Preferably, the support plate has a pentagonal structure, and each corner of the support plate is provided with a bent portion. The bent portion is provided with a fixing screw hole. Both ends of the blade are respectively provided with countersunk holes corresponding to the fixing screw holes. A fixing screw with its inner end threadedly matched to the fixing screw hole is fitted into the countersunk hole.

[0007] Preferably, the corners of two adjacent support plates are staggered.

[0008] Preferably, the support frame includes a top plate fixed to the front top of the mounting bracket, side plates fixed to both ends of the top plate, and a bearing fixed to the lower middle of the side plates. Short shafts that are rotatably fitted and matched with the bearings are respectively fixed to the middle of both ends of the crossbeam.

[0028] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a rotary mower, including a mounting frame 1 for assembly and connection with a skid steer loader and a support frame 2 fixed to the front of the mounting frame 1.

[0030] The support frame 2 includes a top plate 2.1 fixed to the top front of the mounting bracket 1, side plates 2.2 fixed to both ends of the top plate 2.1, and a bearing 2.4 fixed to the lower middle part of the side plate 2.2. To improve the connection strength between the support frame 2 and the mounting bracket 1 and to increase the overall rigidity, multiple stiffening plates 2.3 are horizontally fixedly connected between the front wall of the mounting bracket 1 and the top surface of the top plate 2.1. Multiple positioning through holes 2.2.1 are vertically provided on the front and rear sides of the middle part of the side plate 2.2.

[0031] The rotating shaft component 3 includes a crossbeam 3.1 and a pair of support plates 3.3 fixedly fitted onto the crossbeam 3.1. Short shafts 3.2, which rotatably engage with the bearing seat 2.4, are fixed to the middle portions of both ends of the crossbeam 3.1. The support plates 3.3 have a pentagonal structure, and each corner of the support plate 3.3 has a bent portion 3.3.1, with a fixing screw hole 3.3.2 on the bent portion 3.3.1. The corners of adjacent support plates 3.3 are staggered.

[0032] Multiple blades 4 are evenly distributed circumferentially around two pairs of support plates 3.3, and both ends of the blades 4 are detachably and fixedly connected to the outer edge of the corresponding support plate 3.3. Each end of the blade 4 has a countersunk hole 4.1 corresponding to a fixing screw hole 3.3.2, and a fixing screw 5 is fitted into the countersunk hole 4.1, the inner end of which is threaded and matched with the fixing screw hole 3.3.2. Thus, the installation and removal of a single blade 4 from the support plate 3.3 can be completed by removing and installing the fixing screw 5.

[0033] The drive assembly 6 is located on one side of the support frame 2 and is used to drive the crossbeam 3.1 to rotate. The drive assembly 6 includes a bracket 6.1 vertically fixed to the outer wall of the side plate 2.2 on one side; a motor 6.2 with its housing fixed to the inner wall of the top of the bracket 6.1; a drive sprocket 6.3 located on the outer side of the top of the bracket 6.1 and fixedly mounted on the power output shaft of the motor 6.2; a driven sprocket 6.4 fixedly mounted on the outer end of the corresponding short shaft 3.2; and a chain 6.5 for the transmission connection between the drive sprocket 6.3 and the driven sprocket 6.4. The motor 6.2 is a hydraulic motor, powered by high-pressure hydraulic fluid supplied by the oil pump on the skid steer loader. The motor 6.2 drives the rotating shaft 3 to rotate as a whole through a chain drive mechanism, so that the blade 4 completes the mowing operation by rolling.

[0034] The ski boot 7 is detachably fixed to the bottom of both side walls of the support frame 2. The ski boot 7 includes a sliding plate 7.1 with its front and rear ends bent upwards, and a vertical plate 7.2 with its bottom fixed to the top surface of the sliding plate 7.1 near the outer side. The vertical plate 7.2 has multiple adjusting screw holes 7.2.1 evenly distributed vertically at its front and rear ends. Positioning bolts 8 are fitted into the corresponding positioning through holes 2.2.1 and adjusting screw holes 7.2.1. By aligning the adjusting screw holes 7.2.1 with the positioning through holes 2.2.1 at different heights and fitting the positioning bolts 8, the overall support height of the ski boot 7 can be adjusted, thus facilitating the adjustment of the mowing depth.

[0035] In summary, by assembling and connecting the mounting bracket 1 to the skid steer loader, the skid steer loader can support and move the entire mowing mechanism. During mowing, the bottom of the skid shoe 7's sliding plate 7.1 is supported on the grass and slides, while the motor 6.2 drives the rotating shaft 3 to rotate at high speed through the chain drive mechanism, thereby achieving grass mowing while the blade 4 rolls.

[0036] When one of the blade plates 4 is damaged, the corresponding fixing screws 5 can be removed to facilitate the disassembly and assembly of the blade plate 4, so as to facilitate the replacement or repair of the blade plate 4.
