Description

Technical Field

[0001] The utility model specifically relates to a charge auxiliary device with blasthole protection. Background Art

[0002] During the mining process, after the construction of the downward blasthole is completed, dust, gravel and surface water at the hole mouth are easy to enter the blasthole, causing damage to the blasthole. The activities of personnel during the charging process will increase the probability of these factors damaging the blasthole, which will have an adverse impact on mining production. Therefore, protective measures must be set for the hole mouth during the process from the completion of the mine drilling to the completion of the charging.

[0003] In the actual production process of the mine, after the construction of the downward blasthole is completed, the area around the blasthole mouth is generally soft sand, and the hole mouth is funnel-shaped. The traditional sandbag hole protection method is relatively cumbersome and inefficient, and the sandbags need to be removed during the charging process, which can easily cause debris such as gravel to enter the blasthole during the charging process, causing damage to the blasthole. For this reason, we propose a charging auxiliary device with blasthole protection. Utility Model Content

[0004] The utility model aims to provide a charging auxiliary device with blasthole protection to solve the problem that the traditional sandbag hole protection proposed in the above background technology is relatively cumbersome and inefficient, and debris may enter the blasthole during charging.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a charging auxiliary device with blasthole protection, comprising:

[0006] Cylinder;

[0007] A barrel cover is arranged on the barrel body, and a conical groove is arranged on the lower surface of the barrel cover, and an inlet communicating with the conical groove is opened on the barrel cover;

[0008] The paddle is arranged in the middle of the inner side of the cylinder, and the inner side of the paddle is provided with a rotating shaft which is rotatably matched with the cylinder, and one end of the rotating shaft extends outward from the cylinder to form a rocker.

[0009] It is convenient to place the barrel at the mouth of the bore, place the barrel cover on top of the barrel, put heavy objects such as sand into the conical groove, and press the barrel to fit tightly against the mouth of the bore to complete the work of protecting the bore. When loading powder, first remove the barrel cover, then put the powder roll into the barrel, and at the same time turn the rocker to make the paddle move the powder roll to speed up the falling of the powder roll into the bore.

[0010] Preferably, the cylinder comprises a rubber layer and a stainless steel layer, and the rubber layer is fixed to the outer surface of the stainless steel layer.

[0011] It is convenient to make close contact with the blast hole opening through the rubber layer, so that the outer surface of the cylinder and the blast hole opening form a seal.

[0012] Preferably, the cylinder is conical, and both the upper and lower surfaces of the cylinder are open.

[0013] It is convenient to put the powder roll into the inner side of the hole with smaller diameter through the cylinder.

[0014] Preferably, a handle is fixed on the barrel cover.

[0015] It is convenient to pull the barrel cover to quickly detach or install it from the barrel body.

[0016] Preferably, the cross section of the handle is in the shape of a Chinese character "凵", and a reflective sheet is fixed on the handle.

[0017] It is convenient to attract the operator's attention in a dimly lit environment so as to quickly find the blasthole position for loading.

[0018] Preferably, the barrel cover is made of stainless steel

[0019] It facilitates better corrosion resistance, increases the service life of the device, and increases the practicability of the device.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] This patent avoids the cumbersome traditional sandbag hole protection by providing a barrel cover, a conical groove, a barrel body and a paddle, which requires the removal of the sandbags for charging. The device is easy to operate. By placing the barrel body at the mouth of the blast hole, placing the barrel cover on the top of the barrel body, and putting heavy objects such as sand into the conical groove of the barrel cover, the outer surface of the barrel is pressed to fit closely with the hole mouth, thereby completing the work of protecting the blast hole and preventing debris from entering the inside of the blast hole. When charging, the position of the blast hole can be quickly found according to the reflective sheet. When loading, first use the handle to remove the barrel cover, then put the medicine roll into the barrel body, and at the same time turn the rocker to make the paddle paddle to poke the medicine roll, thereby accelerating the medicine roll to fall into the blast hole, thereby protecting the blast hole and simply and effectively improving the charging efficiency.
