Description

Technical Field

[0001] This utility model relates to the field of small micro-tillers, specifically a mud-blocking small micro-tiller. Background Technology

[0002] When small tillers are working, especially on wet or soft soil, soil is easily thrown up by the rotating blades or wheels. Mudguards can effectively block the splashed soil and prevent it from adhering to critical components such as the engine and transmission system. For operators, mudguards can reduce the amount of soil splashed onto them, which not only improves operating comfort but also avoids operational errors caused by mud obstructing their vision, thereby improving operational safety.

[0003] However, in the operation of traditional mud-blocking mini tillers, mud-blocking devices are usually installed on the mini tillers. These devices use baffles to block mud. As mud accumulates on the surface of the baffles over time, the surface of the baffles becomes uneven. The originally smooth mud-blocking surface is "covered". When mud splashes, it bypasses the baffle through the protrusions of the mud layer, causing mud to splash onto the mini tiller body, engine and other parts, and even onto the operator. Utility Model Content

[0004] The purpose of this utility model is to provide a small, mud-blocking micro-tiller to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A mud-blocking mini tiller includes a mudguard. A first side baffle and a second side baffle are fixedly installed at both ends of the mudguard. A reinforcing rib is fixedly connected to the center of one side of the upper end of the mudguard. A reinforcing crossbar is fixedly connected to one end of each of the reinforcing ribs. Both ends of the reinforcing crossbar are fixedly connected to both ends of the mudguard. A connecting block is fixedly connected to one end of the reinforcing crossbar. A connecting pin is fixedly installed at one end of the reinforcing crossbar. A mud-scraping component for scraping and cleaning the mudguard side is provided on the inner side of the mudguard.

[0007] Preferably, the cleaning and mud-scraping assembly includes a first guide plate, one side of which is fixedly installed on the lower outer side of the mudguard, and a sliding hole is provided through the lower end of the mudguard.

[0008] Preferably, a first sliding block is slidably connected inside the first guide plate, and a sliding connecting rod is fixedly connected to the lower end of the first sliding block. The sliding connecting rod is slidably sleeved inside the sliding hole of the mudguard, and a scraper is fixedly connected to one end of the sliding connecting rod, with the sliding connecting rod located on the lower side of the scraper.

[0009] Preferably, one side surface of the scraper blade is in close contact with the inner side surface of the mudguard, and a movable block is fixedly connected to one side of the upper end of the scraper blade, and a lead screw is rotatably connected inside the movable block.

[0022] Please refer to Figure 1 , Figure 3 As shown, a mud-blocking mini tiller includes a mudguard 1. A first side baffle 2 and a second side baffle 21 are fixedly installed at both ends of the mudguard 1. A reinforcing rib 42 is fixedly connected to the center of one side of the upper end of the mudguard 1. A reinforcing crossbar 41 is fixedly connected to one end of each of the reinforcing ribs 42. Both ends of the reinforcing crossbar 41 are fixedly connected to both ends of the mudguard 1. A connecting block 4 is fixedly connected to one end of the reinforcing crossbar 41. A connecting pin rod 3 is fixedly installed at one end of the reinforcing crossbar 41. A cleaning and mud-scraping assembly 5 for scraping and cleaning the mudguard side is provided on the inner side of the mudguard 1.

[0023] In a specific embodiment, the mudguard 1 serves as the core mudguard component. Its main body has an arc-shaped or inclined planar structure. When the mini-tiller is working, the soil generated by the rotating blades will splash in all directions. The mudguard 1 can directly block most of the upward and backward soil, preventing soil from splashing onto the operator or other parts of the machine. At the same time, the first side baffle 2 and the second side baffle 21 at both ends of the mudguard 1 form a "lateral barrier". However, a small amount of soil will also splash to the left and right sides when the mini-tiller is working.

[0024] Please refer to Figures 1 to 5As shown, as a technical optimization of this utility model, the cleaning and mud scraping assembly 5 includes a first guide plate 51. One side of the first guide plate 51 is fixedly installed on the lower side of the mudguard 1. A sliding hole 11 is opened through the lower end of the mudguard 1. A first sliding block 57 is slidably connected inside the first guide plate 51. A sliding connecting rod 54 is fixedly connected to the lower end of the first sliding block 57. The sliding connecting rod 54 is slidably sleeved inside the sliding hole 11 of the mudguard 1. One end of the sliding connecting rod 54 is fixedly connected to the mud scraper 53, and the sliding connecting rod 54 is located on the lower side of the mud scraper 53.

[0025] Furthermore, one side surface of the scraper 53 is in close contact with the inner surface of the baffle 1. A moving block 58 is fixedly connected to one side of the upper end of the scraper 53. A lead screw 510 is rotatably connected inside the moving block 58. A servo motor 52 is fixedly installed at one end of the lead screw 510. The output shaft of the servo motor 52 is connected to one end of the lead screw 510. One end of the servo motor 52 is fixedly installed at the upper side of the first side baffle 2. The other end of the lead screw 510 is rotatably sleeved inside the upper side of the second side baffle 21. A second guide plate 55 is fixedly installed at the upper side of the opposing sides of the first side baffle 2 and the second side baffle 21. A guide groove 56 is opened inside one side of the second guide plate 55. A second sliding block 59 is slidably connected inside the guide groove 56. One end of the second sliding block 59 is fixedly connected to one side of the moving block 58.

[0026] In a specific embodiment, the mud-scraping assembly 5 mainly consists of a first guide plate 51, a sliding connecting rod 54, a mud scraper 53, a moving block 58, a lead screw 510, a servo motor 52, and a second guide plate 55. When the micro-tiller is working, to prevent the mudguard 1 from being covered and accumulating a large amount of mud, the servo motor 52 is started to drive the lead screw 510 to rotate. The rotation of the lead screw 510 drives the moving block 58 to move along the direction of the lead screw 510. The moving block 58 moves in a straight line through the constraint of the second sliding block 59 and the guide groove 56, so that the mud scraper 53 is located on the inner surface of the mudguard 1, in close contact with the mudguard 1, and begins the mud scraping operation to scrape off the mud or impurities attached to the inner surface of the mudguard 1. The mud scraper 53 is connected to the first sliding block 57 through the sliding connecting rod 54. The sliding connecting rod 54 passes through the sliding hole 11 of the mudguard 1 to realize the linear sliding of the mud scraper 53.

[0027] When this utility model is in use, to prevent the mudguard 1 from accumulating a large amount of mud, the servo motor 52 is started to drive the lead screw 510 to rotate. The rotation of the lead screw 510 drives the moving block 58 to move along the direction of the lead screw 510. The moving block 58 moves in a straight line due to the constraint of the second sliding block 59 and the guide groove 56. As a result, the scraper 53 is located on the inner surface of the mudguard 1 and in close contact with the mudguard 1, and the scraping operation begins. The mud or impurities attached to the inner surface of the mudguard 1 are scraped off. The scraper 53 is connected to the first sliding block 57 through the sliding connecting rod 54. The sliding connecting rod 54 passes through the sliding hole 11 of the mudguard 1 to realize the linear sliding of the scraper 53.
