The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
Figures 1 and 2 show a mechanical material transfer dump truck comprising: a vehicle body 100 and a striker assembly 200. The upper portion of the vehicle body 100 has a diagonal sliding member 110, the material is slidably disposed on the diagonal sliding member 110, and the lower portion of the vehicle body 100 has wheels 120. The striker assembly 200 is connected to the vehicle body 100 and located at the front end of the oblique sliding assembly 110, and the front end of the oblique sliding assembly 110 is the lowest end of the oblique sliding assembly 110. During loading and transportation, the material blocking assembly 200 is arranged above the oblique sliding assembly 110 and blocks materials; when discharging, the material blocking assembly 200 is arranged below the oblique sliding assembly 110, and the material slides down along the oblique sliding assembly 110.
In this scheme, when utilizing this device loading transportation material, keep off material subassembly 200 and arrange slant slip subassembly 110 top in, at first arrange the material in slant slip subassembly 110's working face through mechanical equipment or manpower on, the material slides downwards along slant working face under the effect of gravity, keeps off material subassembly 200 and keeps off until being kept off. After the transportation is completed, when the materials need to be unloaded, the material blocking assembly 200 is moved to the position below the oblique sliding assembly 110, the materials continue to slide along the inclined working face at the moment, the materials slide out of the trolley, the purpose of automatic unloading is achieved, and the material transferring and unloading efficiency is improved.
In this embodiment, the oblique sliding assembly 110 includes a plurality of support shafts 111 and a plurality of rollers 112, two ends of the support shafts 111 are fixed to the vehicle body 100, the plurality of support shafts 111 are uniformly arranged along the oblique sliding direction of the material, a plurality of rollers 112 uniformly arranged along the axial direction are sleeved on each support shaft 111, the rollers 112 are rotatably connected to the support shafts 111, and the material can be placed on the rollers 112. The rolling friction force of the roller 112 is small, so that the material can move along the inclined plane direction conveniently.
In order to prevent the material from sliding down from the two sides and the rear end of the diagonal sliding member 110 during the loading, transporting and discharging processes, the two sides and the rear end of the diagonal sliding member 110 are provided with the balustrade 130.
Since there is a gap between the front end of the slant sliding member 110 and the front end of the cart, in order to prevent the material from sliding off the gap, a support plate 140 is provided below the slant sliding member 110, a through hole 141 is provided on the support plate 140, and the upper portion of the material blocking member 200 can pass through the through hole 141 and be placed at the front end of the slant sliding member 110. The supporting plate 140 mainly plays a role in supporting and transiting when the material is unloaded.

When the materials move to a designated station, the trolley is pushed forwards, the guide shaft 262 abuts against a matching position on the station, the guide shaft 262 is pressed to move inwards along the guide sleeve 261, the steel wire rope 291 is horizontally pulled, the steel wire rope 291 pulls the adjusting rod 280 downwards after passing through the guide pulley 292, the T-shaped rod 230 rotates around the cross rod 240, the long rod 231 moves downwards from the long round hole and finally completely enters the position below the supporting plate 140, and at the moment, the materials can move along the rolling direction of the roller 112 under the action of gravity and are discharged to the designated station. When the unloading of the material is completed, the cart is pulled backwards, and the T-shaped rod 230 reversely rotates around the cross rod 240 under the force of the spring 210, and returns to the initial position. By utilizing the structure, the working state of the material blocking assembly 200 can be controlled very conveniently.
In this embodiment, the bottom of the vehicle body 100 has four legs 150, the legs 150 are mounted with wheels 120, and the wheels 120 include universal wheels and guide wheels.
To facilitate the operation of the cart, a handle 160 is fixed to the cart body 100, and the handle 160 is located at the rear end of the diagonal slide assembly 110.
