Description

Technical Field

[0001] The present invention relates to the field of standing self-propelled equipment, in particular to a standing crawler self-propelled equipment. Background Art

[0002] A snowplow is a self-propelled device that is essential for winter snow removal. It primarily consists of a prime mover, transmission, snow collection and throwing mechanism, a travel system, and an operating system. It uses a snowplow blade or spiral auger to break up and collect ice and snow on the road. The snow throwing mechanism is used to throw the collected snow to the side of the road or collect it in a centralized location.

[0003] On February 22, 2022, the applicant applied for a Chinese utility model patent with application number "CN202220358576.5" and name "A standing zero-turn snowplow", which discloses a standing zero-turn snowplow, specifically including a snowplow body, on which a snowplow mechanism, a control mechanism, a standing mechanism and a driving mechanism are provided. The drive mechanism is connected to the snowplow's tire assembly via a transmission assembly, and the control mechanism controls the transmission assembly and the snowplow mechanism via a power unit. The snowplow's travel mode is tire-driven, which can cause the tires to slip under extremely harsh road conditions. Furthermore, the snowplow lacks height adjustment. The applicant has also simultaneously applied for a Chinese utility model patent, application number CN202220674192.4, entitled "An Operating Panel Structure for a Stand-Up Snowplow," for the control mechanism of this utility model. The patent specifically comprises a panel housing and a control lever assembly, which is disposed on both sides of the upper end of the panel housing to control the rotation of the snowplow's wheels. The control lever assembly includes a left control lever and a right control lever, the left control lever connected to control the snowplow's left tire, and the right control lever connected to control the snowplow's right tire. The left control lever of the control lever assembly can only control the movement of the snowplow and cannot control the rotation of the snowplow auger. Summary of the Invention

[0041] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0042] See Figures 1 to 20 The present invention provides a standing crawler self-propelled device, specifically comprising a device body 1, a control console 4 and a crawler mechanism 9. The rear end of the device body 1 is reversibly mounted with a pedal 2, on which the operator stands when the machine is working; output shafts 3 are symmetrically mounted on both sides of the device body 1; the control console 4 is mounted on the device body 1, on which a travel control lever 6 and a function control lever 7 are movably mounted, with a linkage mechanism 8 provided between the travel control lever 6 and the function control lever 7; one end of the crawler mechanism 9 is connected to the output shaft 3, and the other end is movably hinged to the device body 1 through a height adjustment mechanism 10. Figure 1 and Figure 2 The self-propelled equipment in this embodiment is a snowplow. The travel control lever 6 is used to control the movement of the snowplow. During operation, the travel control lever 6 needs to be kept in a depressed state at all times. The function control lever 7 is used to control the rotation of the snowplow auger at the front end of the snowplow. Pushing the function control lever 7 forward can control the rotation of the snowplow auger.

[0043] See Figure 5 、 Figures 9-11 The height adjustment mechanism 10 includes a height adjustment motor 11 and a swing arm group 12 hinged in the device body 1. The motor seat 13 of the height adjustment motor 11 is hinged in the device body 1. The motor seat 13 is swingably mounted on the corresponding hinge bracket in the device body 1 through a hinge hole; Figure 10 The height-adjusting motor 11 is connected to a push rod 14 through a screw mechanism, and the height-adjusting motor 11 is connected to a screw of a motor seat 13 through a gear reduction mechanism, and a screw seat is installed on the screw rod; the swing arm group 12 includes a first swing arm 15 and a second swing arm 16 fixed to each other; the first swing arm 15 is hinged to the push rod 14, and the second swing arm 16 is hinged to the track mechanism 9; the first swing arm 15 and the second swing arm 16 are welded and fixed by a hinge shaft 17; a travel limit switch 18 is installed on the height-adjusting motor 11, which corresponds to the upper limit position and the lower limit position of the push rod 14, that is, it limits the highest adjustable height and the lowest adjustable height of the snow-clearing cover 46 at the front end of the equipment body 1; a tension spring 5 is connected between the swing arm group 12 and the equipment body 1. By raising the motor 11, the screw seat of the screw mechanism is driven to move, thereby driving the push rod 14 to move, and correspondingly driving the first swing arm 15 and the second swing arm 16 to swing, so that the relative angular position of the crawler mechanism 9 and the device body 1 changes, and the crawler mechanism 9 can swing relative to the device body 1 with the output shaft 3 as the fulcrum, and the crawler 35 of the crawler mechanism 9 is always in contact with the ground, so that the device body 1 can move upward or downward relative to the crawler mechanism through relative movement; the snow-clearing auger is installed in the snow-clearing cover 46 at the front end of the device body 1. When the device body 1 swings upward with the output shaft 3 as the fulcrum, the snow-clearing auger at the far end will be adjusted in height. Figure 9 At this time, the push rod 14 is in the upper limit position, and the snow-clearing cover 46 and the snow-clearing auger are in the highest position relative to the crawler mechanism 9.

[0044] See Figure 12-14 The linkage mechanism 8 includes a slide bar 19, a slide bar seat 20 and a linkage block 21. The slide bar 19 is slidably mounted on the slide bar seat 20. One side of the slide bar 19 is in contact with the travel control rod 6. The linkage block 21 is hingedly mounted on the hinge bracket 22 in the control console 4. The linkage block 21 is provided with a linkage slot 23 that can engage with the function control rod 7. When the travel control rod 6 and the function control rod 7 work together, the function control rod 7 is manually pushed to push it into the linkage slot 23. The slide bar seat 20 is mounted on the hinge bracket 22. A reset spring 24 is installed between the linkage block 21 and the hinge bracket 22. The operator can control the two control rods to work in conjunction with each other, or to reset the two control rods. By simply releasing the external force applied to the travel control rod 6, the linkage block 21 is reset to disengage the function control rod 7 from the linkage slot 23. The reset of the function control rod 7 stops the snow auger at the front end of the snowplow. The function control rod 7 can also be manually pushed to disengage the linkage slot 23 for reset. Figure 14 The slide bar 19 is slidably matched with the slide bar seat 20 through the double-rod structure, and the guiding effect is good.

[0045] See Figure 14 and Figure 17 , a downwardly extending sliding shaft 25 is formed at one end of the slide rod 19, and the sliding shaft 25 cooperates with the first waist-shaped groove 26 of the linkage block 21, and the linkage block 21 is pushed to rotate by the sliding shaft 25; the hinged bracket 22 is provided with a gear slot 27 for placing the function control lever 7. When the linkage is in the working state, a "7"-shaped groove is formed between the linkage block 21 and the gear slot 27; refer to Figure 17 (The figure shows two gear positions of the function control lever 7, which is indicated by a two-dot chain line in the figure). One side of the linkage block 21 protrudes outward to form a guide flange (triangular in shape), and the upper end of the guide flange forms a linkage slot 23. When the function control lever 7 is manually released from the linkage working state, it needs to pass over the guide flange to reset itself.

[0046] See Figure 15 and Figure 16, the lower end of the function control lever 7 is provided with a driving plate 28, and a bracket piece 29 is slidably mounted on one side of the driving plate 28. The bracket piece 29 is fixed to the first gear rotating shaft 30 in the control console 4, and the bracket piece 29 is arranged perpendicular to the axis of the first gear rotating shaft 30; the driving plate 28 is slidably mounted on the first gear rotating shaft 30, and a compression spring 31 is installed between the shaft ends of the driving plate 28 and the first gear rotating shaft 30. The compression spring 31 is used to always press the driving plate 28 so that the pressing driving plate 28 remains perpendicular to the first gear rotating shaft 30; when it is necessary to manually release the joint work, the function control lever 7 is pushed along the axial direction of the first gear rotating shaft 30, so that the driving plate 28 is deflected with the upper end edge 32 of the bracket piece 29 as the fulcrum, so that the function control lever 7 is disengaged from the linkage slot 23. The lower end of the travel drive rod 6 is hinged to a gear seat 55, which is fixed to a second gear rotation shaft 56 within the control console 4 (the travel drive rod 6 can move relative to the gear seat 55 along the axial direction of the second gear rotation shaft 56). A spring-loaded safety switch is mounted on the gear seat 55. During operation, the travel drive rod 6 is always in a depressed position, ensuring that the travel drive rod 6 and the safety switch are always in contact (in this embodiment, releasing the travel drive rod 6 causes the device to shut down; however, releasing the travel drive rod 6 can also be configured to stop the device as needed). The drive plate 28 is mounted on the guide pin 33 of the bracket plate 29 and is attached to the first gear rotation shaft 30 via the second kidney-shaped groove 34. This structure allows the function control lever 7 to swing laterally (in the axial direction of the first gear rotation shaft 30). This swinging of the function control lever 7 can be used to disengage the linkage slot 23, thereby releasing the linkage with the travel control lever 6. That is, when the function control lever 7 and the travel control lever 6 are working in conjunction, the function control lever 7 can be pushed along the axial direction of the first gear rotation axis 30 to disengage it from the linkage slot 23, and the linkage state is manually released (at this time, the travel drive lever 6 is still in the pressed down state and is always in contact with the safety switch), the function control lever 7 is reset, and the snow auger stops rotating.

[0047] See Figure 5-Figure 8 The crawler mechanism 9 includes a crawler 35, a transmission gear 36, and a support frame 37. The output shaft 3 is connected to the transmission gear 36 via a bearing seat 38. The transmission gear 36 cooperates with the through-groove 39 of the crawler 35. The output shaft 3 of the equipment body 1 drives the transmission gear 36 to rotate. The transmission gear 36 drives the crawler 35 to run through the engagement of its teeth with the through-groove 39. Multiple pairs of guide teeth 40 are evenly distributed on the inner side of the crawler 35. A guide cavity 41 corresponding to the transmission gear 36 is formed between each pair of guide teeth 40. The transmission gear 36 also plays the role of guiding the crawler 35. By applying the crawler mechanism 9 to the snowplow and using the crawler to transmit the movement, the application range of the snowplow is improved. Figure 5 , the crawler mechanism 9 is symmetrically installed on both sides of the equipment body 1, and the two crawler mechanisms 9 are fixedly connected by a supporting link. Figure 5 One end of the crawler mechanism 9 is connected to the output shaft 3, and the other end is movably hinged to the second rocker arm 16 of the rocker arm group 12.

[0048] See Figure 5 and Figure 6 , load-bearing wheels 42 are installed on both sides of the lower end of the support frame 37, and a V-shaped frame 43 and a floating guide wheel 44 installed on the V-shaped frame 43 are movably hinged at the lower end of the support frame 37. The floating guide wheel 44 can play a load-bearing role. When the track 35 encounters an obstacle during its movement, the V-shaped frame 43 can be swung at any time so that one of the floating guide wheels 44 of the V-shaped frame 43 can still play a load-bearing role, thereby improving the grip of the track 35; the load-bearing wheels 42 and the floating guide wheels 44 are placed on the outside of the guide teeth 40, which can play a role in guiding the track 35. A tensioning wheel 45 that can be used to adjust the tightness of the track 35 is installed on the support frame 37. The tensioning wheel 45 falls into the guide cavity 41 accordingly, which can also play a role in guiding the track 35.

[0049] See Figure 18 and Figure 19 A snow cover 47 is rotatably mounted on the snow removal cover 46 at the front end of the device body 1. A gear ring 48 is provided at the lower end of the snow removal cover 47. A steering motor 49 and a steering gear 50 meshing with the gear ring 48 are provided on the snow removal cover 46. The steering motor 49 drives the steering gear 50 and the gear ring 48 to rotate, thereby driving the entire snow removal cover 47 to rotate circumferentially. Figure 20 , the upper end of the snow cover 47 is hingedly installed with a first snow-clearing cap 57 and a second snow-clearing cap 58, a flip connecting rod 59 is hinged between the second snow-clearing cap 58 and the snow-clearing cap 47, and a snow-clearing cap spring 60 is installed between the second snow-clearing cap 58 and the snow-clearing cap 47; an angle adjustment mechanism 61 is installed on the snow-clearing cover shell 46, and the angle adjustment mechanism 61 includes an adjusting motor 62, an adjusting gear 63 and a sector gear 64 meshing with the adjusting gear 63, a wire wheel 65 is fixedly installed on the sector gear 64, and a pull rope 66 connected to the first snow-clearing cap 57 is wound on the wire wheel 65, and the snow throwing angle of the two snow-clearing caps is adjusted by pulling / moving the pull rope 66; Figure 21 That is, it is a three-dimensional picture when the snow throwing angle of the two snowplow caps is adjusted to face downward.

[0050] See Figure 2-Figure 4 The device body 1 is provided with a pedal fixing plate 51, to which a locking plate 52 is hingedly connected. The pedal fixing plate 51 is provided with a locking groove 53. The locking plate 52 is used to rotate the locking pin 54 of the pedal 2 and lock it into the locking groove 53. To unlock the pedal 2, simply push the locking plate 52 upward to disengage it from the locking pin 54. At this time, the pedal 2 is flipped downward under the influence of its own gravity.

[0051] This embodiment can be applied to the field of snow sweepers. Through the crawler-type travel transmission, the snow sweeping cover and the snow sweeping auger on the equipment body can be lifted relative to the crawler mechanism to avoid damage by external forces when the snow sweeping auger is not working; it can simultaneously control the travel control lever and the function control lever through the linkage mechanism, and the function control lever can also be manually toggled to disengage the linkage state. Figure 22 This is a prototype of the present invention applied to a snowplow. Its various functions are effective and easy to promote and use. It can be applied not only to snowplows, but also to sweepers, snow pushers, lawn mowers, and other equipment.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
