Description

Technical Field

[0001] The utility model relates to a feeding device, belonging to the technical field of packaging material breaking. Background Art

[0002] Drilling fluid is a general term for various circulating fluids that meet the needs of drilling work with their multiple functions during the drilling process. Drilling fluid can be divided into clean water, mud, clay-free phase flushing fluid, emulsion, foam and compressed air according to its composition. Clean water is the earliest drilling fluid used. It does not require treatment and is easy to use. It is suitable for intact rock formations and areas with sufficient water sources. Mud is a widely used drilling fluid, mainly suitable for unstable rock formations such as loose, fractured, prone to collapse and falling blocks, and swelling and peeling when exposed to water. When preparing drilling fluid, its additives are mostly packaged in plastic bags, woven bags and ton bags. Therefore, when preparing drilling fluid, a bag breaking device will be used for rapid feeding.

[0003] Numerous devices are currently available for breaking packaging bags. For example, Chinese utility model patent No. CN218086433U discloses a ton bag cutting device. The device comprises a platform with a feed port fixedly connected to its upper end. A bag-breaking mechanism is located within the platform for cutting the bags. The bag-breaking mechanism includes a cutter and a conical head. The cutter reciprocates to cut the bags. The conical head has a conical upper end for puncturing the bags. The cutter is provided in three sets and arranged in a circular pattern around the axis of the conical head. This ton bag cutting device uses the bag-breaking mechanism to drive the cutter to reciprocate, thereby automatically cutting the ton bags. However, drilling fluids are complex in composition and typically require the use of a variety of additives. While the aforementioned bag-breaking mechanism works well for additives packaged in large ton bags, it may not be able to effectively reach smaller bags of additives that require small additions. Consequently, the bag-breaking mechanism fails to break the bag, causing the material to enter the mixing device directly, creating safety hazards and affecting feeding efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a feeding device which can effectively break packaging bags of different sizes when feeding drilling fluid additives, thereby improving the safety and efficiency of feeding.

[0005] In order to achieve the above objectives, the technical solution adopted by the present utility model is:

[0006] A feeding device includes a feed hopper and a central bag breaking mechanism installed in the feed hopper. The feed hopper is provided with a feeding port. A side bag breaking knife is provided in the feed hopper near the feeding port. The side bag breaking knife is provided at the edge of the feeding port and has an upward cutting edge so that it can be used for manually holding the bag to break the bag.

[0007] This feeding device features a side bag-breaking cutter located near the feeding port of the hopper. This allows workers to directly pierce or cut the small bags of material into the hopper. The central bag-breaking mechanism and the side bag-breaking cutter work together to break bags of varying sizes, enabling fast and safe feeding. This feeding device can be used for rapid feeding of drilling fluid additives.

[0008] Furthermore, the side bag breaking cutters are provided with more than two, for example, the side bag breaking cutters are evenly distributed near the feeding port, so that it is convenient for manual feeding at different positions of the feeding device.

[0009] Furthermore, the side bag breaking knife includes a side bag breaking blade support and a side bag breaking blade with an upward-facing blade disposed on the side bag breaking blade support. The blade support is connected to a portion of the feed hopper near the feeding port. For example, the side bag breaking blade extends horizontally.

[0010] To prevent material from splashing out of the hopper after bag breaking, which could cause material waste, the feed hopper inlet is further equipped with an inwardly extending annular baffle plate located above the side bag-breaking cutter. Small bags of material require manual opening with the side bag-breaking cutter, which requires manual operation close to the feed hopper inlet. The annular baffle plate prevents material from splashing out of the hopper after bag breaking and reduces potential harm to humans.

[0011] Furthermore, the annular baffle is horizontally arranged. The horizontally arranged annular baffle can temporarily place the small bag materials, share part of the gravity of the small bag materials for manual labor, and reduce manual physical labor consumption.

[0012] Furthermore, the central bag breaking mechanism includes a support frame, which includes multiple legs; one end of each leg is connected to the side wall of the feed hopper, and the other end extends toward the feeding port of the feed hopper, and the other ends of all the legs are gathered together; each leg is upwardly provided with a bag breaking blade with the blade facing upward, and the extension direction of each bag breaking blade is consistent with the extension direction of the leg where it is located, and one end of each bag breaking blade is gathered together to form a bag breaking tip.

[0013] Furthermore, the bottom of the feed hopper is provided with a feeding port; the feeding device also includes a feed hopper support base; the support base is provided with a barrier assembly for adjusting the size of the feed port at the bottom of the feed hopper. The barrier assembly can be used to control the amount of material released from the feed port.

[0014] Furthermore, the barrier assembly includes a barrier plate and a barrier plate movable guide rail. The barrier plate movable guide rail is fixedly connected to the feed hopper support base. When in use, the barrier plate moves along the barrier plate movable guide rail to adjust the size of the feed opening at the bottom of the feed hopper. To ensure the barrier assembly has higher stability, the barrier plate movable guide rail is further provided on both sides of the barrier plate.

[0015] In order to improve the convenience of moving the feeding device, the feed hopper is further provided with a suspension assembly for connecting with the suspension device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with specific implementation methods.

[0023] Example 1

[0024] The feeding device of this embodiment, such as Figures 1 to 5 As shown, it includes a feed hopper 5, a central bag breaking mechanism 4 and a feed hopper support base 1. The feed hopper 5 is installed on the feed hopper support base 1. The feed hopper 5 includes a cylindrical upper feeding part and a conical funnel-shaped lower discharge part connected to the upper feeding part. The top opening of the upper feeding part forms a feeding port, and the bottom opening of the lower discharge part forms a feeding port 7.

[0025] The central bag-breaking mechanism 4 includes a tripod support frame, a bag-breaking blade 42, and a connecting block 43. The bottoms of the three legs 41 of the tripod support frame are connected to the side walls of the lower feeding section via the connecting block 43. The upper portions of the three legs converge at the middle of the upper feeding section to form the top of the tripod support frame. The upward-facing side of each leg 41 is provided with the aforementioned bag-breaking blade 42, with the cutting edge of the bag-breaking blade 42 facing upward. The bag-breaking blade 42 extends along the length of the leg and the bag-breaking blades 42 on the three legs converge at the top of the tripod support frame to form a bag-breaking tip 44. The tripod support frame, connecting block, bag-breaking blade, and feed hopper are all made of metal and are connected by welding, making them more secure during use and less likely to loosen.

[0026] The inner wall surface of the upper feeding part of the feed hopper 5 is symmetrically provided with bag breaking knives 3 on both sides near the upper edge. The side bag breaking knives 3 include side bag breaking blades and a side bag breaking blade support frame. The side bag breaking blade support frame includes a horizontal leg and an oblique leg. One end of the horizontal leg and one end of the oblique leg are welded to the side wall of the upper feeding part of the feed hopper, and the other end of the horizontal leg and the other end of the oblique leg are welded together. The side bag breaking blades are welded to the upward side of the horizontal support leg, and the side bag breaking blades extend horizontally with the blades facing upward. When it is necessary to put in a bag of material with smaller loading materials, the bag can be broken manually by using the side bag breaking knife 3 set on the inner side of the feed hopper 5.

[0027] The upper edge of the feed hopper 5 is provided with an annular baffle 8 extending inwardly and parallel to a horizontal plane of a certain width. The annular baffle 8 is annular in shape, and its outer edge is fixed to the upper edge of the upper feeding portion. The annular baffle 8 not only prevents material from splashing out of the feed hopper and causing material waste, but also prevents material splashing and dust generation when manually opening bags with the side bag breaker, which could cause harm to people.

[0028] The outer wall surface of the upper feeding part of the feed hopper 5 near the upper edge is symmetrically provided with a suspension assembly 6. The suspension assembly 6 is connected to the feed hopper 5 by welding. The suspension assembly 6 includes a U-shaped connecting plate 61 and a lug plate 63 connected to the U-shaped connecting plate 61. The lug plate 63 is provided with a hanging hole 62. The feed hopper and the suspension assembly are both made of metal. When installing the suspension assembly 6, the U-shaped connecting plate 61 is first attached to the outer wall surface near the upper edge of the upper feeding part and then welded. The connection and installation by welding makes it more secure during use. When the feeding device needs to be moved, the hook of the external suspension equipment can be hung in the hanging hole 62 on the lug plate 63, that is, the entire device is suspended for transportation. When the feed hopper 5 is transported to a designated place, the feed hopper support base 1 can fix the feed hopper 5 in the designated position.

[0029] The feed hopper support base 1 includes three columns supported on the side of the lower discharge part and three crossbeams connecting the three columns in pairs. A rectangular hole is opened in the middle of one of the crossbeams in the horizontal direction and passes through the crossbeam. A barrier assembly 2 is inserted into the rectangular hole. The barrier assembly includes a partition plate 23 and a partition plate moving guide rail 24. Two channel steels with parallel notches facing each other pass through the rectangular hole and are fixed to the crossbeam to form a partition plate moving guide rail 24. When the partition plate 23 slides in the guide rail, it can completely block the feed port. A sliding stop plate 22 is set at the end of the partition plate 23 away from the feed port to prevent the partition plate from sliding forward after the partition plate 23 completely blocks the feed port 7. A pull-out groove 21 is set on the sliding stop plate 22. When the feed amount needs to be adjusted, the gap between the partition plate 23 and the feed port 7 is adjusted by pulling out the pull-out groove 21, thereby controlling the feed flow rate of the feed hopper 5.

[0030] When the feeding device of this embodiment is used to feed drilling fluid additives, the operator throws the additive material packaging bag into the feed hopper 5, and the bag-breaking tip 44 punctures the packaging bag. The same bag-breaking blade 42 can further cut the packaging bag, achieving rapid bag-breaking, allowing the additive material inside to fall into the feed hopper 5 for rapid feeding. When encountering smaller packaging bags, the side bag-breaking blades 3 on both sides of the feed hopper 5 are used to facilitate puncturing. This method is not only convenient to operate, but also can quickly and safely puncture the additive material packaging bag. During use, the feed flow rate of the feed hopper 5 can be controlled by adjusting the barrier spacing of the barrier assembly 2.

[0031] Example 2

[0032] The feeding device of this embodiment differs from the drilling fluid feeding device of Example 1 only in that this embodiment does not include an annular baffle plate on the inner side of the upper edge of the feed hopper inlet, and the number of side bag breaking cutters is set to one. This requires manual operation to break the small packages of material while standing in a fixed position. However, the material is prone to splashing out of the feed hopper during the feeding process, and the operator needs to move away from the feeding device as soon as possible after breaking the bag.

[0033] Example 3

[0034] The feeding device of this embodiment differs from the drilling fluid feeding device of Example 1 only in that the annular baffle plate of this embodiment is not parallel to the horizontal plane and is slightly inclined from the periphery to the center. In this case, the baffle plate can still provide good protection for the human body.

[0035] Example 4

[0036] The feeding device of this embodiment is different from the drilling fluid feeding device of Example 1 only in that: in this embodiment, no baffle assembly is provided on the feed hopper support base, and the feeding device controls the feed amount by controlling the amount of input material when in use.
