Description

Technical Field

[0001] This utility model relates to the field of snow removal technology, and in particular to an emergency snow removal device. Background Technology

[0002] During winter snowfall, roads, airport runways, squares and other public areas are easily covered by snow. If not cleared in time, it will lead to slippery roads, reduced visibility, seriously affecting traffic efficiency, and even causing traffic accidents, threatening public travel safety and the normal operation of the city. Therefore, emergency snow removal operations have become one of the key tasks to ensure public safety in winter. Traditional emergency snow removal devices mostly rely on snow throwers and centrifugal fans to remove snow. The core principle is to suck up the snow on the road and throw it to the side of the road through the snow thrower.

[0003] However, in actual snow removal scenarios, snow is often mixed with various impurities such as tree branches, gravel, and food bags. Traditional devices lack effective impurity pretreatment and separation mechanisms, which makes it easy for these impurities to enter the snow-throwing tube along with the snow. Hard or large impurities such as tree branches and gravel can directly impact and wear down the centrifugal fan blades, while light impurities such as food bags can easily adhere to the snow-throwing channel or centrifugal fan components. This can not only block the snow-throwing path and reduce snow removal efficiency, but may also cause the equipment to stop due to impurities entangled in the fan shaft.

[0004] Therefore, this application provides an emergency snow removal device to meet the needs. Utility Model Content

[0035] like Figures 1 to 6As shown, an embodiment of this utility model provides an emergency snow removal device, including a snow removal device 1. A filter box 2 is arranged behind the snow removal device 1. The filter box 2 contains a filter assembly 3 and a protective assembly 4. A through groove 204 is opened on the top of the filter box 2, and a snow throwing tube is connected above the through groove 204. A mounting frame is fixedly connected to the snow removal device 1. The filter assembly 3 is inclined and is used to separate branches and gravel. The protective assembly 4 is installed in the through groove 204 and is used to protect the centrifugal fan inside the snow throwing tube. The snow removal device 1 includes an arc plate 101 and... The auger 102 has a through groove 103 on the arc plate 101, which connects the arc plate 101 and the filter box 2. The snow removal equipment 1 is mounted on the carrier via a mounting frame. The snow removal equipment 1 is controlled by a hydraulic pump on the carrier. By setting the filter box 2 behind the snow removal equipment 1, impurities such as branches and gravel mixed in the snow are separated in advance, preventing impurities from entering the snow throwing tube with the snow. This reduces the wear and jamming risk of the centrifugal fan from the source, extends the service life of the core components of the snow throwing tube, reduces the probability of equipment failure, and ensures the stable operation of emergency snow removal.

[0036] like Figures 2 to 4 As shown, the filter box 2 includes a box body 201, inside which are a collection box 1 202 and a collection box 203. Collection box 1 202 is used to collect small debris such as gravel, and collection box 203 is used to collect larger debris such as branches. The upper part of collection box 203 corresponds to the through groove 1 204. The filter assembly 3 includes a connecting plate 301 and a motor 1 303. An elastic screen 302 is fixedly connected inside the connecting plate 301. The drive end of motor 1 303 is driven by a drive shaft 1 304. Multiple eccentric wheels 305 are sleeved on the drive shaft 1 304. The connecting plate 301 is located at the collection box 202. Above the first collection box 202, the first motor 303 is installed below the elastic screen 302. Through the inclined elastic screen 302, combined with the vibration structure of the eccentric wheel 305 driven by the first motor 303, gravity assists in the separation of branches and gravel. Small particles of gravel enter the first collection box 202 through the filter holes, while large branches remain on the plate and move to the end, eventually entering the second collection box 203. The vibration of the eccentric wheel 305 reduces the residue of impurities on the elastic screen 302 and prevents impurities from clogging the filter holes, ensuring unobstructed filtration channels and significantly improving the separation efficiency and thoroughness of branches and gravel.

[0037] like Figure 5 and Figure 6As shown, the protective component 4 includes a second motor 401 and a strip filter plate 408. The drive end of the second motor 401 is driven by a second drive shaft 402. An incomplete gear 403 is sleeved on the second drive shaft 402. The strip filter plate 408 is installed in the through groove 204. A cleaning plate 407 is provided in the filter through hole of the strip filter plate 408. The cleaning plate 407 can rotate in the filter through hole. The bottom of the cleaning plate 407 passes through the filter through hole and is fixedly connected to a connecting block 405. A fixing rod 404 is provided inside the filter box 2. The connecting block 405 and the fixing rod 404 are connected together. The connecting block 405 is slidably connected to the drive shaft 402. A rack 406 is provided on the side of the connecting block 405 near the drive shaft 402. The rack 406 is meshed with the incomplete gear 403. Through the transmission structure of the motor 401, drive shaft 402, incomplete gear 403 and rack 406, the connecting block 405 is driven to slide back and forth along the fixed rod 404, thereby driving the cleaning plate 407 to rotate in the through hole of the strip filter plate 408, removing light impurities such as food bags blocked by the strip filter plate 408, preventing them from being sucked into the snow throwing tube, and protecting the centrifugal fan inside the snow throwing tube.

[0038] The working principle of the technical solution provided by this utility model is as follows:

[0039] Centrifugal fan and auger 102 draw snow and impurities from the road surface into filter box 2 through channel 2 103. Snow passes through strip filter plate 408 into snow throwing tube and eventually flies to the roadside. Debris such as branches and gravel enter filter box 2 and fall onto elastic screen 302 under gravity. Smaller impurities such as gravel pass through the filter holes of elastic screen 302 into collection box 202 below. Due to the inclined setting of elastic screen 302, larger impurities such as branches move along elastic screen 302 to the end and finally fall into collection box 203. During this process, motor 303 drives the eccentric wheel 305 on drive shaft 304 to rotate, thereby causing the upper elastic screen 302 to vibrate up and down continuously, accelerating the movement speed of larger impurities such as branches and preventing them from staying on elastic screen 302. On the other hand, it prevents smaller impurities such as gravel from clogging the filter holes, improving the separation efficiency of branches and gravel.

[0040] For impurities such as food bags that are easily blown away, they reach the strip filter plate 408 along with the snow. The large size of the food bags is blocked by the strip filter plate 408, but due to the suction of the centrifugal fan above, they will be adsorbed below the strip filter plate 408, affecting the snow removal effect. The motor 401 drives the incomplete gear 403 on the drive shaft 402 to rotate. Since the rack 406 is meshed with the incomplete gear 403, it drives the connecting block 405 to slide back and forth around the fixed rod 404. This causes the cleaning plate 407 on the connecting block 405 to rotate back and forth in the filter holes of the strip filter plate 408, moving the food bags adsorbed below the strip filter plate 408 to an area away from the influence of the centrifugal fan. The food bags finally fall into the collection box 203 under the action of gravity, protecting the centrifugal fan inside the snow throwing tube.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
