Description

Technical Field

[0001] The utility model relates to the technical field of material crushing vehicles, in particular to a crushing mechanism of a material crushing vehicle. Background Art

[0002] The material crushing vehicle is a special vehicle that integrates collection, crushing and transportation. It is specially designed for the current status of garden waste treatment in China. From the perspective of reducing garden waste and reducing transportation costs, it provides garden waste generating units with more maneuverable and more convenient mobile garden waste crushing equipment. It can be widely used in the collection, transportation and crushing of green garbage in various scenic spots, parks, schools, communities and on both sides of municipal roads.

[0003] The crushing mechanism of the existing material crushing truck has a maximum limit on the diameter of the crushed tree trunks. When the diameter exceeds a certain degree, direct crushing cannot be completed. It needs to be cut and reduced in diameter before it can be crushed by the crushing roller of the crushing mechanism. After market research, many crushing mechanisms have a trunk crushing diameter of 10CM and 15CM. Our company can currently achieve a trunk crushing diameter of 20CM, but in actual use, we still encounter trunks with a diameter of more than 20CM, which makes it impossible to handle them on site in time. They need to be transported to a place specializing in handling large-diameter trunks for pre-treatment before subsequent crushing. Not only does it require more transport vehicles and more staff, it also requires more transportation costs and labor costs, occupies a larger processing site, and affects the use effect. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a crushing mechanism of a material crushing vehicle, which is used to solve the problem that the crushing mechanism of the existing material crushing vehicle has limited requirements on the diameter of crushed tree trunks, which affects the actual use effect.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A crushing mechanism of a material crushing vehicle, comprising a crushing bucket, a crushing roller arranged in the crushing bucket, a pad arranged below the crushing roller, and a feed hopper hinged to the crushing bucket and supported by a longitudinal beam of the material crushing vehicle, wherein a through slot is arranged at a position of the crushing bucket corresponding to the pad, a bottom cover plate adapted to the through slot is hingedly connected to a side of the through slot away from the feed hopper, and the pad plate is fixedly mounted on the bottom cover plate;

[0007] A flip push rod is hingedly installed between the crushing bucket and the bottom cover plate, a support frame is fixedly connected to the lower part of the bottom cover plate close to the feed hopper, a locking push rod is fixedly installed on the inner side of the longitudinal beam, a locking plug rod movably inserted in the through hole of the longitudinal beam is provided below the locking push rod, the locking push rod is connected to the locking plug rod through a connecting plate, and a high-position plug hole and a low-position plug hole corresponding to the locking plug rod are provided on the support frame.

[0008] Preferably, a pad block matching the shape of the lower surface of the feed hopper is fixedly mounted on the longitudinal beam.

[0009] Preferably, there are no less than two groups of flip push rods, which are symmetrically arranged front and back below the bottom cover plate.

[0010] Preferably, there are no less than two groups of locking rods, which are symmetrically inserted into the support frame front and back.

[0011] Preferably, the angle between the high-position jack and the low-position jack is equal to the flip angle of the bottom cover.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model drives the bottom cover plate to flip downward by a flip push rod, and drives the locking plug rod to lock the bottom cover plate in position before and after the flipping by a locking push rod. Before the bottom cover plate is flipped, it can be used to crush tree trunks of conventional diameters. After the bottom cover plate is flipped downward, the distance between the pad and the crushing roller is increased, and tree trunks with larger diameters can be accommodated, thereby increasing the diameter range of the crushed tree trunks. There is no need to handle tree trunks with larger diameters separately, which saves use costs and improves practicality. It solves the problem that the crushing mechanism of the existing material crushing vehicle has limited requirements on the diameter of the crushed tree trunks, which affects the actual use effect.

DETAILED DESCRIPTION

[0019] 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.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a crushing mechanism of a material crushing vehicle, comprising a crushing bucket 1, a crushing roller 2 arranged in the crushing bucket 1, a pad 3 arranged below the crushing roller 2, and a feed hopper 5 hinged to the crushing bucket 1 and supported by a longitudinal beam 4 of the material crushing vehicle, and a pad 12 adapted to the shape of the lower surface of the feed hopper 5 is fixedly installed on the longitudinal beam 4;

[0021] A through slot 101 is provided at the position of the crushing bucket 1 corresponding to the backing plate 3, and a bottom cover plate 6 adapted to the through slot 101 is hingedly connected to the side of the through slot 101 away from the feed hopper 5, and the backing plate 3 is fixedly mounted on the bottom cover plate 6, and a flip push rod 7 is hingedly installed between the crushing bucket 1 and the bottom cover plate 6, and there are no less than two groups of flip push rods 7, which are symmetrically arranged front and back below the bottom cover plate 6;

[0022] A support frame 8 is fixedly connected to the lower part of the bottom cover plate 6 near the side of the feed hopper 5, a locking push rod 9 is fixedly installed on the inner side of the longitudinal beam 4, and a locking plug rod 10 movably inserted in the through hole of the longitudinal beam 4 is arranged below the locking push rod 9. There are no less than two groups of locking plug rods 10, which are symmetrically inserted on the support frame 8 front and back. The locking push rod 9 is connected to the locking plug rod 10 through a connecting plate 11, and a high-position plug hole 801 and a low-position plug hole 802 corresponding to the locking plug rod 10 are arranged on the support frame 8, and the angle between the high-position plug hole 801 and the low-position plug hole 802 is equal to the flipping angle of the bottom cover plate 6.

[0023] Working principle: The flip push rod 7 drives the bottom cover plate 6 to flip downward, and the locking push rod 9 drives the locking rod 10 to lock the bottom cover plate 6 before and after the flipping. Before the bottom cover plate 6 is flipped, it can be used to crush tree trunks of conventional diameter. After the bottom cover plate 6 is flipped downward, the distance between the pad 3 and the crushing roller 2 is increased, and it can accommodate tree trunks with larger diameters, thereby increasing the diameter range of the crushed tree trunks.
