Description

Technical Field

[0001] The present invention relates to the technical field of cement bag opening, and particularly to a cement bag opening device for engineering construction. Background Art

[0002] In actual bridge pile foundation construction work, there are often environments where concrete mixer trucks cannot enter the site. It is necessary to manually prepare the concrete mixture, which requires cement, stones, and water to be stirred and mixed. After opening the cement bags, the cement is poured into the feeding hopper of the concrete mixer. The transportation work is usually carried out manually with the help of lifting tools for transporting the cement bags. However, manual bag opening is still required. There are also some cement bag openers that can automatically open the cement bags, but their structures are large, and the installation, debugging, and commissioning outdoors are cumbersome. Manual handling is still required, and their flexibility for outdoor use is poor. Currently, the cement bag opening device for engineering construction has a large amount of dust generated during manual bag opening, which is highly harmful. Manual handling is also time-consuming and laborious, and there are easily potential safety hazards. It is not convenient to be directly installed on the bucket of a stone transport loader for cement handling and bag opening work. At the same time, the manual bag opening method is prone to incomplete cutting and residual cement, which is not convenient for back suction to reduce residues. At the same time, the cement stored outdoors is prone to caking due to moisture, which is not convenient to check for caking during cement bag opening, and it is likely to cause potential hazards such as reduced concrete strength.

By controlling the bucket to move downward and backward, the cement bag insertion tube 104 can be inserted into the cement bag. At this time, the cement bag insertion tube 104 can hook the cement bag. After the cement bag is opened and the cement is discharged, the suction fan 204 can be started. With the filtration of the filter element on the isolation cover 203, a small amount of residual cement in the cement bag can be isolated. There is no need for manual handling of cement, which is labor-saving and does not damage the respiratory system of workers, and also improves the functionality of the existing loader bucket.

[0040] In the embodiment of the present disclosure, the swing bag opening member 3 includes: a swing arm 301, a connecting arm shaft 3011, a torsion spring 302, a swing control column 303 and an end cover 304. The swing arm 301 is provided with two, and the two swing arms 301 are respectively rotatably mounted on the two swing shafts 1011; the connecting arm shaft 3011 is fixedly mounted on the two swing arms 301; the two swing shafts 1011 are respectively sleeved with torsion springs 302, and one end of the two torsion springs 302 is respectively connected to the two swing arms 301; the other ends of the two torsion springs 302 are respectively The two swing arms 301 are connected to the ends of the two swing shafts 1011; the lower ends of the two swing arms 301 are respectively plugged with swing control columns 303, and the ends of the two swing control columns 303 are respectively threadedly connected with end caps 304; the swing control columns 303 are used to toggle the swing arms 301 to rotate; the bag opening and cutting member 5 includes: a bottom bag opening knife 501 and a side bag opening knife 502, the bottom bag opening knife 501 is fixedly installed on the connecting arm shaft 3011, and the bottom of the bottom bag opening knife 501 is provided with a serrated blade; the bottom bag opening knife 501 is used to cut the bottom of the cement bag The connecting arm shaft 3011 is fixedly provided with a row of side bag opening knives 502, and the blade surface of the row of side bag opening knives 502 is a sawtooth structure; the row of side bag opening knives 502 is used for vertically cutting cement bags; the bag opening and cutting member 5 is used in conjunction with the swinging bag opening member 3, so that the bag opening and cutting work of the cement bag can be automatically performed, without manual operation, which is safer, and can open multiple bags of cement at the same time. The method of cutting cement bags in both horizontal and vertical directions can ensure the cement discharge efficiency, reduce cement residue, and is simple to control and easy to operate. The bag opening is realized by mechanical automation and has strong durability for outdoor use. When the cement bag is lifted by the cement bag insertion tube 104 and transported to the mixer hopper, the bucket height is lowered, driving the swing control column 303 to move downward. The swing control column 303 is squeezed by the edge of the mixer hopper, which can drive the swing arm 301 to rotate, driving the bottom bag opening knife 501 and the side bag opening knife 502 to swing, the side bag opening knife 502 cuts the cement bag vertically, and the bottom bag opening knife 501 cuts the bottom of the cement bag, thereby realizing bag opening by cutting in two directions of the side and bottom of the cement bag.

[0041] In the embodiments of the present disclosure, the particle separator 4 includes: a rear baffle 401 and a sieve plate 402. The rear baffle 401 is fixedly installed on the connecting arm shaft 3011; the sieve plate 402 is fixedly installed on the connecting arm shaft 3011, and a row of slots is provided on the sieve plate 402; the sieve plate 402 is used to isolate cement lumps; by using the particle separator 4, the sieve plate 402 can be used to screen and isolate the lumps in the cement, preventing the problem that the lumps in the cement stack are not found due to factors such as moisture, which affects the strength of the concrete. This structure uses the sieve plate 402, which has a simple structure and can be directly observed by the staff, with stronger practicability. The sieve plate 402 adopted corresponds to the opening of the cement bag on the side of the bag opening knife 502, and full screening is carried out to improve the quality of cement bag opening and feeding. As the cement bag is cut, the discharged cement first passes through the sieve plate 402 for screening, and the larger lumps can be isolated. The rear baffle 401 can block at the rear side to facilitate the full screening of the cement by the sieve plate 402 at the front side.

[0042] In the embodiments of the present disclosure, the dust-proof spraying member 6 includes: a pump head seat 601, an elastic steel sheet 602, a raised head 6021, and a spraying pump head 603. The pump head seat 601 is fixedly installed on the swing arm 301 on the same side of the water tank 102; an elastic steel sheet 602 is fixedly installed on the swing arm 301 on the same side of the water tank 102, and a raised head 6021 is fixedly installed on the elastic steel sheet 602; the end of the raised head 6021 is an arc-shaped structure; the spraying pump head 603 is fixedly installed on the pump head seat 601; the raised head 6021 is aligned with the spraying pump head 603; the spraying pump head 603 is connected to the water tank 102 through a hose; the dust-proof spraying member 6 further includes: a spray strip 604, the spray strip 604 is fixedly installed on the connecting arm shaft 3011, and the spray strip 604 is connected to the spraying pump head 603 through a hose; a row of nozzles is provided on the spray strip 604; the spray strip 604 is used for dust suppression when the cement bag is opened; the spraying control member 7 includes: a swing connecting plate 701 and a wave pressing plate 702, the swing connecting plate 701 is fixedly installed on the swing rotating shaft 1011 on the same side of the water tank 102; a wave pressing plate 702 is fixedly installed on the swing connecting plate 701; the wave pressing plate 702 is a wave-shaped structure; the wave pressing plate 702 is used for fitting and pressing the end of the raised head 6021; the dust-proof spraying member 6 can automatically perform dust reduction work during the process of opening and discharging the cement bag in this structure, improving the construction environment quality. Especially when the bottom opening knife 501 and the side opening knife 502 pierce the cement bag during opening, under the action of the air pressure in the cement bag, the extruded cement dust can be reduced by this structure. At the same time, it is also convenient to apply moisture to the cement bag after it is emptied, further improving the dust-free effect when the staff recycles the cement bag waste and improving the environmental protection quality of the construction site. This structure can automatically control atomization during the rotation of the swing arm 301, which is more practical. The loader driver can complete the work of opening the cement bag alone. During the rotation of the swing arm 301, driving the raised head 6021 can be squeezed and moved by the wave pressing plate 702, and then the spraying pump head 603 can be pressed to realize spraying and dust removal through the spray strip 604. Using the elasticity of the elastic steel sheet 602 can ensure that the raised head 6021 elastically fits outside the wave pressing plate 702 for extrusion control.

[0043] Embodiment 2. On the basis of Embodiment 1, the extended adapter 8 includes: an extension rod 801 and a counterweight ball 802. The extension rod 801 is rotatably sleeved on the swing control column 303; a counterweight ball 802 is fixedly installed at the bottom of the extension rod 801; the counterweight ball 802 is used to abut against the ground; the end cap 304 is used to limit the extension rod 801. By using the extended adapter 8, the versatility of this structure can be increased. It can be determined whether to use the extended adapter 8 according to actual needs. When there is no mixer hopper and it is necessary to mix cement and stones on the ground, the extended adapter 8 can facilitate the control of the swing arm 301 to swing for bag opening work, improving the versatility of this structure in different scenarios and no longer relying on the extrusion of the edge of the mixer hopper. The structure of the extended adapter 8 is simple, and the disassembly and installation are convenient. At the same time, the extension rod 801 that naturally hangs down by gravity does not affect the normal excavation of stones by the bucket either.

[0044] The working principle of this embodiment: First, when it is necessary to discharge cement into the mixer hopper, the bucket connecting frame 101 is welded to the bottom of the loader bucket, or the bucket connecting frame 101 can be drilled and installed on the bottom of the loader bucket through bolts, as shown in the appendix Figure 2, at this time, the driver drives the loader to move to the stack of cement pallets, and can control the movement of the bucket. If the cement bags to be transported are skewed, the push plate 103 can be adjusted to simply push them flat, which is convenient for subsequent bag opening. By controlling the bucket to move down and backward, the cement bag insertion pipe 104 can be inserted into the cement bag. The driver can control the bucket to make the end of the cement bag insertion pipe 104 tilt upward to prevent the cement bag from falling off. At this time, the cement bag insertion pipe 104 can hook the cement bag. Then, the driver can drive the loader to move to the hopper of the mixer, control the cement bag to align with the hopper of the mixer, and align any one of the swing control columns 303 with the edge of the hopper of the mixer. At this time, lower the height of the bucket to drive the swing control column 303 to move down. The swing control column 303 is squeezed by the edge of the hopper of the mixer, and then the swing arm 301 can be driven to rotate. At this time, the swing arm 301 can drive the bottom bag-opening knife 501 and the side bag-opening knife 502 on the connecting arm shaft 3011 to rotate. The side bag-opening knife 502 cuts the cement bag vertically, and the bottom bag-opening knife 501 cuts the bottom of the cement bag, realizing bag opening by cutting in two directions, namely the side and the bottom of the cement bag. Then the cement can be smoothly discharged into the hopper of the mixer. As the cement discharge is completed, lift the bucket. Under the elastic control of the torsion spring 302, the swing arm 301 can rotate in the reverse direction and reset, which is convenient for subsequent continuous bag opening of cement bags. When the swing arm 301 is controlled to rotate, the rear baffle 401 and the leakage plate 402 can be driven to swing to the bottom of the cement bag at the same time. At this time, as the cement bag is cut, the discharged cement first passes through the screening of the leakage plate 402, and larger lumps can be isolated. The driver or staff can observe whether there are granular lumps. After the cement bag is opened and the cement is discharged, before the next cement transportation, the suction fan 204 can be started. With the filtration of the filter element on the isolation cover 203, a small amount of cement remaining in the cement bag can be isolated. Then rotate and disassemble the isolation cover 203 to remove the cement cleaning and collecting pipe 202. The emptied cement bag can be manually removed or the cement bag insertion pipe 104 can be lowered to fit the ground. Using the friction of the ground on the cement bag, move the bucket forward to drive the cement bag insertion pipe 104 to move forward to realize the extraction from the cement bag. During the rotation of the swing arm 301, the spraying pump head 603 is driven to rotate at the same time. At this time, the raised head 6021 is also driven to rotate. The swing connecting plate 701 is fixed on the side of the swing rotating shaft 1011. With the extrusion of the wave-shaped extrusion plate 702, the raised head 6021 can be extruded and moved, and then the spraying pump head 603 can be pressed. At this time, the spraying pump head 603 can suck pure water from the water tank 102 and spray it for dust removal through the spray strip 604;

[0045] When it is necessary to directly open the cement bag and discharge it to the ground, insert the extension rod 801 into the swing control column 303, and tighten the end cap 304 at the end of the swing control column 303. The end cap 304 does not squeeze or contact the extension rod 801 and does not affect the rotation of the extension rod 801. Under the gravitational traction of the counterweight ball 802, the extension rod 801 remains vertical, and the counterweight ball 802 fits against the ground. At this time, when the falling bucket is lowered, under the limit extrusion of the extension rod 801, the swing arm 301 will also be controlled to rotate, driving the bag-opening cutting member 5 to perform the bag-opening operation.
