[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figure 1-8 As shown, a rear-flip hydraulic flap unloading machine includes a rear-flip hydraulic flap unloading machine 1, wherein a fixed seat 2 is arranged on the top of the flap of the rear-flip hydraulic flap unloading machine 1, and two fixed seats 2 are arranged in parallel along both sides of the rear end of the flap; a blocking member 3 that can slide back and forth is arranged between the two fixed seats 2, and a fixing mechanism for limiting the blocking member 3 is arranged between the two ends of the blocking member 3 and the corresponding fixed seats 2.
[0028] As a specific embodiment, the fixing mechanism is a fixing pin 4, and the fixing seat 2 is provided with a plurality of first pin holes 21 arranged along the front-to-back direction. The two ends of the blocking member 3 are respectively provided with second pin holes 35 horizontally corresponding to the corresponding first pin holes 21, and the fixing pin 4 is inserted into the corresponding overlapping first pin holes 21 and the second pin holes 35 to realize the fixed connection between the blocking member 3 and the fixing seat 2.
[0029] Specifically, the fixing pin 4 includes a pin body 41 and a pin head 42. The pin body 41 is used to be inserted into the corresponding first pin hole 21 and the second pin hole 35 for fixing, and the pin head 42 is used to prevent the pin body 41 from completely entering the pin hole, so as to facilitate pulling out the fixing pin through the pin head 42.
[0030] When the front and rear position of the blocking member 3 needs to be adjusted, the fixing pin 4 is pulled out from the corresponding first pin hole 21 and second pin hole 35, and then the blocking member 3 is moved and adjusted to a suitable front and rear position, and the second pin hole 35 is made to coincide with one of the first pin holes 21, and then the fixing pin 4 is reinserted to complete the front and rear position adjustment of the blocking member 3. The front and rear position adjustment of the blocking member 3 is determined according to the length from the tail of the truck to the rear wheel that actually needs to be unloaded. When the rear wheel of the truck is lower than the front side of the blocking member 3, the unloading port of the truck is vertically flush with the tail of the rear-flip hydraulic plate unloader 1.
[0031] Furthermore, if Figure 7 As shown, the first pin holes 21 are arranged in two rows, and the first pin holes 21 in the upper and lower rows are arranged horizontally and staggered. In this way, firstly, the total number of the first pin holes 21 is increased, the continuity of the position adjustment of the blocking member 3 is improved, and it can be applied to more different types of trucks for unloading; secondly, the spacing between the first pin holes 21 in the same horizontal plane is larger, and the support between two adjacent first pin holes 21 is thicker, so as to ensure the force strength of the fixing seat 2.
[0032] Furthermore, if Figure 4-6 As shown, the blocking member 3 includes two blocking parts 31, which are in direct contact with the rear tire of the truck to be unloaded, and the two blocking parts 31 are transitionally connected through a second connecting part 34. The outer sides of the two blocking parts 31 (the side opposite to the two blocking parts 31 is the outer side) are respectively provided with joint parts 32, and the joint parts 32 are transitionally connected with the blocking parts 31 through a first connecting part 33, and the second pin hole 35 is provided on the joint parts 32. Specifically, the blocking part 31 is arranged in a rearward convex structure to increase the contact area with the flap of the rear-flip hydraulic flap unloading machine 1, improve the friction between the blocking member 3 and the flap, and increase the force strength of the blocking member 3.
[0033] Working principle: Before unloading, first measure the actual length from the unloading port of the unloading truck to the rear wheel, then pull out the fixing pin 4 from the corresponding first pin hole 21 and second pin hole 35, then move the blocking member 3 and adjust it to a suitable front and rear position, and at the same time make the second pin hole 35 coincide with one of the first pin holes 21, and then reinsert the fixing pin 4 to complete the front and rear position adjustment of the blocking member 3. When the rear wheels of the truck are lowered to the front side of the blocking member 3, the unloading port of the truck is vertically flush with the tail of the rear-flip hydraulic flap unloader 1. In this way, when the truck unloads bulk materials, the materials flow out from the tail end of the rear-flip hydraulic flap unloader 1, preventing the materials from accumulating on the flap of the rear-flip hydraulic flap unloader 1.
[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
