Description

Technical Field

[0001] This utility model belongs to the field of river emergency repair construction technology, and in particular relates to an automatic bagging device for sand and gravel materials in river emergency repair construction. Background Technology

[0002] River channel repair is an important construction project in water conservancy projects. Specifically, it involves repairing rivers after they have been damaged by natural disasters such as floods. Through this repair work, the dikes, slopes and other structures on the river channel are reinforced.

[0003] Large quantities of sand and gravel are needed during river repair work. These materials are used for purposes such as concrete pouring and blocking river channels. The sand and gravel need to be bagged and transported to the construction site.

[0004] The amount of sand and gravel used during construction is very large, resulting in a significant consumption of bagged materials. During the bagging process, the conveyor feeds the sand and gravel into the hopper, and the operator needs to align the opening of the burlap bag with the discharge port of the hopper. Therefore, the bag opening needs to be kept fully open during the discharge process to facilitate the entry of the stone.

[0005] In actual operation, operator errors often result in the bag opening not being wide enough, causing a large amount of stone to spill out, and even injuring the operator's foot.

[0006] As the stones are added to the bag, the weight of the bag gradually increases, resulting in a very heavy workload for the workers during the bagging process, which is quite strenuous.

[0007] Meanwhile, during the bagging process, operators need to open the bag opening with their hands, and if the operation is not done properly, falling stones can easily injure the operator's hands, such as if the bag opening is not properly aligned. Furthermore, this bagging method is very inefficient. Therefore, the current bagging method is not only unsafe and labor-intensive, but also extremely strenuous. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide an automatic bagging device for sand and gravel materials used in river emergency repair construction.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An automatic bagging device for sand and gravel used in river repair work includes a stone feeding hopper, the discharge end of which is connected to an expansion discharge cylinder, and a bag mouth clamping mechanism is installed on the expansion discharge cylinder.

[0011] The bag clamping mechanism includes arc-shaped bag holders symmetrically arranged on both sides of the expansion and discharge cylinder. During the stone bagging process, the bag opening is clamped to the outer wall of the expansion and discharge cylinder by the arc-shaped bag holders.

[0012] The bag clamping mechanism also includes a cylinder that pushes the arc-shaped bag holder against the expanding discharge cylinder. A cylinder mounting bracket is fixedly installed on the cylinder, and the cylinder mounting bracket is fixedly installed on the stone hopper.

[0013] The automatic bagging device for sand and gravel used in river repair construction also includes a bag guide mechanism located below the stone hopper. After bagging, the bag is guided downhill by the bag guide mechanism.

[0014] Preferably, the stone feeding hopper includes an inverted hopper section, the bottom of which is integrally formed with a conical hopper section, the bottom of which is integrally formed with a tubular discharge section, and the expanding discharge cylinder is connected to the tubular discharge section.

[0015] Preferably, a sliding guide structure is installed on the arc-shaped card holder;

[0016] The sliding guide structure includes a sliding guide rod fixedly connected to the tubular discharge section, and a protrusion slidably connected to the top of the arc-shaped bag holder.

[0017] Preferably, the piston rod of the cylinder is fixedly connected to a push rod that is slidably connected to the cylinder mounting bracket, and the push rod is fixedly connected to the arc-shaped bag seat.

[0018] Preferably, a spring is sleeved on the push rod, and the two ends of the spring are respectively fixedly connected to the arc-shaped bag seat and the cylinder mounting bracket.

[0019] Preferably, the upper end of the cylinder mounting bracket is fastened to the outer wall of the mouth-shaped bucket by fastening bolts;

[0020] The bottom of the cylinder mounting bracket has an integrally formed protruding bracket portion, and the cylinder barrel of the cylinder is fixedly mounted on the protruding bracket portion.

[0021] Preferably, the bag material downhill guiding mechanism includes downhill frames spaced apart on both sides, and a plurality of rotating rollers are rotatably connected between the downhill frames.

[0022] Preferably, the downhill frame includes a horizontal frame section, and both ends of the horizontal frame section are integrally formed with inclined frame sections that are inclined downwards;

[0023] The top of the horizontal frame is fixedly connected to a support frame installed on the outer wall of the mouth-shaped bucket.

[0024] Preferably, the support frame includes a fixed seat fixedly installed on the mouth-shaped bucket part, a vertical frame fixedly connected to the bottom of the fixed seat, the vertical frame being welded to the horizontal frame part, and inclined brackets being welded to both sides of the vertical frame, the inclined brackets being welded to the horizontal frame part.

[0025] This utility model has the following beneficial effects:

[0026] 1. This system frees up the operator's hands during the bagging process, eliminating the need for the operator to open the bag. A bag-mouth clamping mechanism is installed on the expanding and discharging cylinder. This mechanism clamps the bag tightly as it is placed inside the cylinder. Firstly, it eliminates the need for the operator to open the bag. Secondly, it avoids the problem of stones spilling from the bag opening during bagging, and prevents stones from hitting the hands when the bag is opened. Furthermore, the clamping force helps support the weight of the bag after the stones enter, further reducing labor intensity during bagging.

[0027] 2. During the operation, under the push of the cylinder, the push rod first clamps the two arc-shaped bag holders on both sides onto the expanding discharge cylinder. At this time, the bag opening is already on the expanding discharge cylinder. Under the clamping of the two arc-shaped bag holders, the bag opening is clamped and locked. At this time, the stone falls freely from the expanding discharge cylinder into the bag. Due to the clamping, the weight of the entire bag is supported.

[0028] Once bagging is complete, the cylinder closes, and with the restoring force of the spring, the arc-shaped bag holders on both sides quickly detach from the bag opening. Under the force of gravity, the bag opening falls from the discharge cylinder and is then secured.

[0029] The above method not only saves labor, but also prevents material spillage during bagging, and the stones will not hit the operators. In addition, the method enables rapid bagging and greatly increases the safety of bagging.

[0030] 3. During the operation, after the bag is filled and the opening is tied, the bag is laid down and, under the action of gravity, the bag slides down the rotating rollers connected between the inclined frame parts. Attached Figure Description

[0040] Example 1

[0041] like Figure 1-4 As shown, an automatic bagging device for sand and gravel used in river repair construction includes a stone feeding hopper 1 (during operation, as in existing methods, a conveyor such as a belt conveyor feeds the stone into the stone feeding hopper 1).

[0042] The specific shape of the stone feeding hopper 1 is as follows: The stone feeding hopper 1 includes an open-mouthed hopper section 11, the bottom of which is integrally formed with a conical hopper section 12, and the bottom of which is integrally formed with a tubular discharge section 13, which is connected to an expanding discharge cylinder 14. The diameter of the expanding discharge cylinder 14 corresponds to the diameter of the bagged material bag.

[0043] Meanwhile, to free up the operator's hands during the bagging process and eliminate the need for the operator to open the bag opening, a bag opening clamping mechanism 2 is installed on the aforementioned expanding and discharging cylinder 14. The bag opening clamping mechanism 2 clamps the woven bag as it is placed into the expanding and discharging cylinder 14.

[0044] This method eliminates the need for operators to open the bag. It also avoids the problem of stones spilling out of the bag during the filling process and the risk of stones hitting hands when the bag is opened. Furthermore, because the bag is clamped, the clamping force helps support the weight of the bag after the stones enter it, thus saving effort during the filling process.

[0045] Specifically, the bag clamping mechanism 2 includes arc-shaped bag holders 23 symmetrically arranged on both sides of the expansion and discharge cylinder 14, the arc of which corresponds to half the arc of the expansion and discharge cylinder 14.

[0046] Meanwhile, the bag clamping mechanism 2 also includes a cylinder 22 that pushes the arc-shaped bag holder 23 against the expanding discharge cylinder 14. A cylinder mounting bracket 21 is fixedly installed on the cylinder 22, and the cylinder mounting bracket 21 is fixedly installed on the stone hopper 1.

[0047] Specifically, the piston rod of cylinder 22 is fixedly connected to a push rod that is slidably connected to the cylinder mounting bracket 21, and the push rod is fixedly connected to the arc-shaped pocket seat 23. A spring 25 is sleeved on the push rod, and the two ends of the spring 25 are respectively fixedly connected to the arc-shaped pocket seat 23 and the cylinder mounting bracket 21.

[0048] The upper end of the cylinder mounting bracket 21 is fastened to the outer wall of the mouth-shaped bucket 11 by fastening bolts; the bottom of the cylinder mounting bracket 21 is integrally formed with a protruding bracket part, and the cylinder of the cylinder 22 is fixedly mounted on the protruding bracket part.

[0049] During operation, driven by cylinder 22, the push rod first clamps the two arc-shaped bag holders 23 onto the expanding discharge cylinder 14. At this time, the bag opening is already on the expanding discharge cylinder 14. Under the clamping of the two arc-shaped bag holders 23, the bag opening is clamped and locked. At this time, the stone falls freely from the expanding discharge cylinder 14 into the bag. Due to the clamping, the weight of the entire bag is supported (the operator only needs to lift it gently to keep the bag from falling off).

[0050] When the bagging is complete, the cylinder 22 closes. With the restoring force of the spring, the arc-shaped bag holders 23 on both sides quickly detach from the bag opening. With the help of gravity, the bag opening falls from the discharge cylinder 14 and is tied.

[0051] The above method not only saves labor, but also prevents material spillage during bagging, and the stones will not hit the operators. In addition, the method enables rapid bagging and greatly increases the safety of bagging.

[0052] In order to improve the accuracy of the movement of the arc-shaped bag holder 23 during operation, a sliding guide structure is installed on the arc-shaped bag holder 23. The sliding guide structure includes a sliding guide rod 24 fixedly connected to the tubular discharge section, and a protrusion 241 that is slidably connected to the sliding guide rod 24 is fixedly connected to the top of the arc-shaped bag holder 23.

[0053] Example 2

[0054] like Figure 1-4 As shown, based on the structure of Embodiment 1, in order to facilitate the unloading of the bag after bagging, the above-mentioned automatic bagging device for sand and gravel in river emergency repair construction also includes a bag material downhill guide mechanism 4 located below the stone unloading hopper 1. After bagging, the bag is guided downhill by the bag material downhill guide mechanism 4.

[0055] The bag material sloping guide mechanism 4 includes sloping frames spaced apart on both sides, with a plurality of rotating rollers 43 rotatably connected between the sloping frames. The sloping frame includes a horizontal frame section 41, and inclined frame sections 42 are integrally formed at both ends of the horizontal frame section 41. At the same time, a support frame 3 installed on the outer wall of the mouth-shaped hopper section 11 is fixedly connected to the top of the horizontal frame section 41.

[0056] The support frame 3 includes a fixed base 33 fixedly mounted on the hopper section 11. A vertical bracket 31 is fixedly connected to the bottom of the fixed base 33. The vertical bracket 31 is welded to the horizontal frame section 41. Inclined brackets 32 are welded to both sides of the vertical bracket 31 and are also welded to the horizontal frame section 41. The support frame structure is used to increase the stability of the hopper.

[0057] After the bag is filled and the opening is tied tightly during operation, the bag is laid down and, under the action of gravity, it slides down the rotating roller 43 connected between the inclined frame parts 42.

[0058] In actual operation, according to the existing method of installing the hopper on the belt conveyor frame, the bottom of the inclined frame 42 is welded with mounting bases (mounting screw holes are opened on the mounting bases) to install the entire device onto the frame of the belt conveyor. Specifically, the mounting bases are fastened to the frame with bolts, so that after the material bag slides down from the inclined frame 42, it falls directly onto the belt conveyor and is directly sent to the stacking area for stacking by the belt conveyor.

[0059] This method greatly improves production efficiency and reduces labor workload. When faced with heavy stone bags, this method not only saves labor and ensures high operational safety, but also significantly improves production efficiency.

[0060] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
