[0016] In the figure: a discharge pipe 1, a waste collection box 2, a hydraulic cylinder 3, a box cover 4, a collar 5, a shaft rod 6, a side plate 7, a through hole 8, a connecting pipe 9, a sealing cloth 10, a counterweight 11, and a laser lamp 12. Specific implementation method:

[0017] 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 of 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.

[0018] like Figure 1 , Figure 2 , Figure 3As shown, a cover device for a waste collection box comprises a discharge pipe 1 and a waste collection box 2 placed below the discharge pipe 1, and also comprises a hydraulic cylinder 3 arranged on both sides of the discharge pipe 1, a box cover 4 is arranged between the discharge pipe 1 and the waste collection box 2, the cylinder body of the hydraulic cylinder 3 is fixed to the outer wall of the discharge pipe 1, the telescopic end of the hydraulic cylinder 3 is fixed to the sleeve 5, the sleeve 5 is sleeved on the shaft rod 6, the inner ring of the sleeve 5 is elliptical, the shaft rod 6 has a movable gap in the inner ring of the sleeve 5 for slight movement up and down and slight tilt left and right, and the two ends of the shaft rod 6 are connected to the top of the box cover 4 through the side plates 7 The box cover 4 is fixed at the top of the waste collection box 2, and the telescopic end of the hydraulic cylinder 3 lifts the shaft rod 6 through the collar 5 to drive the box cover 4 to rise and fall. The box cover 4 can be lowered to cover the top of the waste collection box 2. The deadweight of the box cover 4 and the movable gap make it possible to have a slight gap for the box cover 4 to adjust up and down and left and right, so as to avoid the box cover 4 being not tightly covered because the waste collection box 2 is not placed flat when the hydraulic cylinder 3 drives the box cover 4 to cover the top of the waste collection box 2. The self-adjustment of the box cover 4 can match the top of the waste collection box 2 and buckle tightly.

[0019] A through hole 8 is provided at the top of the box cover 4 corresponding to the outlet of the discharge pipe 1. The tar residue discharged from the discharge pipe 1 falls into the waste collection box 2 through the through hole 8. A connecting pipe 9 is provided on the through hole 8 and is sleeved on the outside of the discharge pipe 1. The bottom end of the connecting pipe 9 is fixed to the box cover 4, and a sealing cloth 10 is fixed between the top of the connecting pipe 9 and the outer wall of the discharge pipe 1. The connecting pipe 9 and the sealing cloth 10 seal the outlet of the waste collection box 2 and the discharge pipe 1 to prevent dust from leaking out. The sealing cloth 10 is made of high-temperature varnished cloth, which is widely used in industry. It has the characteristics of high temperature resistance and softness, and can adapt to the bending of the box cover 4 when rising and falling. The inner diameter of the connecting pipe 9 is larger than the outer diameter of the discharge pipe 1, so that the connecting pipe 9 can be sleeved on the outside of the discharge pipe 1.

[0020] A plurality of counterweights 11 are fixed to the top of the box cover 4 to increase the weight of the box cover 4 so that the box cover 4 can cover the waste collection box 2 more tightly.

[0021] A laser lamp 12 is fixed to the bottom edge of the box cover 4. When the box cover 4 is raised or lowered, the laser lamp 12 emits a laser line downward along the edge of the box cover 4 to indicate that the middle position is the position of the waste collection box 2, so that the waste collection box 2 can be aligned when it is placed back to the bottom of the box cover 4, so that the box cover 4 can be smoothly covered on the top of the waste collection box 2.

[0022] Working principle: When the tar residue is discharged normally, the telescopic end of the hydraulic cylinder 3 descends, so that the box cover 4 covers the top of the waste collection box 2, and the tar residue is discharged from the outlet of the discharge pipe 1 and enters the waste collection box 2 through the connecting pipe 9 and the through hole 8 of the box cover 4. In this process, the top of the waste collection box 2 is closed to prevent dust and volatile substances from leaking out, thereby reducing environmental pollution.

[0023] When replacing or moving the waste collection box 2, first the telescopic end of the hydraulic cylinder 3 is raised, and the shaft rod 6 is suspended by the collar 5 to drive the box cover 4 to rise. After moving the waste collection box 2, it is moved back to the bottom of the box cover 4. At this time, the laser lamp 12 emits a laser line to guide the position of the original waste collection box 2. After the waste collection box 2 is put back, the telescopic end of the hydraulic cylinder 3 is then lowered, and the box cover 4 is covered back on the top of the waste collection box 2. Since the box cover 4 has a slight gap for up and down and left and right adjustment, it is prevented that when the hydraulic cylinder 3 drives the box cover 4 to cover the top of the waste collection box 2, the cover is not tightly closed due to the uneven placement of the waste collection box 2.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
