Description
Technical Field
[0001] This utility model relates to the field of hopper equipment technology, specifically to a hopper safety device with lifting and protection functions. Background Technology
[0002] In the current field of hopper equipment technology, hoppers are widely used in material handling and storage. However, existing hoppers have revealed many safety hazards in actual use. For example, when loading and unloading materials, workers may accidentally approach the edge of the hopper, which can easily lead to accidents where materials fall and injure them. For instance, the hopper rotating and lifting device disclosed in prior art document CN202021876583.1 mainly focuses on the rotation and lifting functions of the hopper, but does not pay sufficient attention to edge protection. At some construction sites, due to the lack of effective protection for the hopper, accidental material spillage poses a serious threat to the personal safety of nearby workers.
[0003] For example, during the hoisting of hoppers, if the hopper structure is unstable or the protective devices are missing, materials may fall during the hoisting process, causing not only material loss but also damage to equipment and personnel below. In some large construction sites, insufficient hopper protection during hoisting often leads to materials scattering, damaging construction equipment, delaying the construction schedule, and even causing injuries or fatalities.

[0005] To achieve the above objectives, this utility model provides a hopper safety device with lifting and protective functions, including a hopper body, a movable baffle body is provided on the top outer side of the hopper body, a large lifting ring is installed on the top side of the hopper body, a small lifting ring is installed on the top side of the movable baffle body, and the outer wall of the hopper body and the outer wall of the movable baffle body are connected by a lifting component, the lifting component includes a guide cylinder and a guide rod that slide and cooperate with each other, the guide cylinder is connected to the outer wall of the hopper body, and the upper end of the guide rod is connected to the outer wall of the movable baffle body.
[0006] This device features a movable baffle body located on the outer top of the hopper body. Large and small lifting rings are used for hoisting the hopper body and the movable baffle body, respectively. A lifting component consisting of a guide cylinder and a guide rod connects the two. The guide cylinder is fixed to the hopper body, and the guide rod is connected to the movable baffle body. The sliding cooperation between the two enables the movable baffle body to rise and fall relative to the hopper body.
[0007] Preferably, the movable baffle body is composed of a U-shaped structure made of three steel plates, located on two sides and one back.
[0008] The main body of this baffle is composed of three steel plates forming a U-shaped structure, which provides shielding from two sides and a back, forming a semi-enclosed protective area.
[0009] Preferably, the bottom of the hopper body is equipped with several pads.
[0010] This feature involves installing several pads at the bottom of the hopper body to create a certain gap between the bottom of the hopper and the ground.
[0011] Preferably, a handle is installed on the outer wall of the movable baffle body, a protrusion is formed in the middle of the handle, a support rod is horizontally arranged on the protrusion, one end of the support rod is welded and fixed to the outer wall of the movable baffle body, and both ends of the handle are welded and fixed to the outer wall of the movable baffle body.
[0012] This feature includes a handle installed on the side wall of the movable baffle body, providing a point of leverage for workers; the protrusion of the handle is the gripping part, and the support rod and both ends of the handle are welded to the movable baffle body to form a stable connection.
[0013] Preferably, a limiting baffle is installed at the bottom of the guide rod, and the top of the guide cylinder narrows to form a limiting ring, so that the limiting baffle always slides along the inner wall of the guide cylinder. When the movable baffle body moves to the highest height, the limiting ring sits on the limiting baffle and can never come out of the guide cylinder; when the movable baffle moves to the lowest height, the movable baffle body sits on the limiting ring, and the guide cylinder supports the movable baffle body.
[0014] This feature includes a limit baffle that slides against the inner wall of the guide cylinder, restricting the sliding stroke of the guide rod within the guide cylinder and thus controlling the displacement distance of the movable baffle.
[0015] Preferably, both the outer sides of the hopper body and the movable baffle body are fitted with edge-sealing channel steel.
[0016] This feature involves installing edge-wrapping channel steel on the outer sides of the hopper body and the movable baffle body. The channel steel wraps around the outer sides to enhance the structural connection strength.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In this hopper safety device with lifting and protection function, the main body of the movable baffle is composed of three steel plates forming a U-shaped structure, which can shield the two sides and the back. When the hopper is loading and unloading materials, it can effectively prevent materials from falling accidentally and avoid injuring nearby workers. It makes up for the shortcomings of devices such as CN202021876583.1 that only focus on the hopper's rotation and lifting function and neglect edge protection devices, and significantly improves operational safety.

Whether for delicate loading and unloading operations at low heights or for material storage protection at high heights, it provides targeted protection, greatly enhancing the applicability of hopper protection. Simultaneously, the limiting baffle at the lower end of the guide rod slides against the inner wall of the guide cylinder, ensuring the movable baffle body remains stable during lifting and lowering, effectively preventing protection failure due to swaying and guaranteeing the reliability of hopper protection under various working conditions.
[0020] The handle on the side wall of the movable baffle body makes it easy for staff to push and pull the movable baffle body to achieve lifting and lowering operations, reducing the difficulty of manual operation and improving work efficiency.
[0021] In addition, the edging channel steel installed on the outer side of the hopper body and the movable baffle body enhances the overall structural strength of the hopper. During hoisting, it can better resist material impact and external collisions, preventing materials from falling due to structural damage. This not only ensures the safety of material transportation but also reduces equipment maintenance costs, providing a safer, more reliable, and more efficient solution for material handling and storage.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] This utility model provides a hopper safety device with lifting and protection functions, such as Figure 1 , Figure 5 As shown, the device includes a hopper body 4, a movable baffle body 3 is provided on the outer side of the top of the hopper body 4, a large lifting ring 1 is installed on the top side of the hopper body 4, a small lifting ring 2 is installed on the top side of the movable baffle body 3, and the outer wall of the hopper body 4 and the outer wall of the movable baffle body 3 are connected by a lifting component 6. The lifting component 6 includes a guide cylinder 61 and a guide rod 62 that slide and cooperate with each other. The guide cylinder 61 is connected to the outer wall of the hopper body 4, and the upper end of the guide rod 62 is connected to the outer wall of the movable baffle body 3.
[0031] A movable baffle body 3 is installed on the outer side of the top of the hopper body 4. A large lifting ring 1 and a small lifting ring 2 installed on the top side of the movable baffle body 3 are used for lifting both. A lifting component 6, consisting of a guide cylinder 61 and a guide rod 62, connects the hopper body 4 and the movable baffle body 3. The guide cylinder 61 is fixed to the outer wall of the hopper body 4, and the upper end of the guide rod 62 is connected to the outer wall of the movable baffle body 3. The sliding cooperation between the guide cylinder 61 and the guide rod 62 enables the movable baffle body 3 to rise and fall relative to the hopper body 4. The movable baffle body 3 can be raised during material loading and unloading to form a protective barrier, preventing materials from falling and injuring people; it can be lowered during lifting to reduce its overall volume, facilitating transportation and storage. The large lifting ring 1 and the small lifting ring 2 make the lifting of the hopper body 4 and the movable baffle body 3 more flexible, allowing for separate or overall lifting as needed. The lifting component 6 provides a stable lifting structure, ensuring that the movable baffle body 3 can be adjusted in position as needed, improving the safety and convenience of using the hopper.
[0032] like Figure 2As shown, the movable baffle body 3 consists of a U-shaped structure made of three steel plates, located on two sides and one back of the movable baffle body 3, forming a semi-enclosed protective area. The U-shaped baffle body 3 can effectively prevent materials from sliding or splashing from the sides and back of the hopper. Compared with open or simple protective structures, it greatly improves the protection range and effect for personnel and equipment around the hopper, especially during material loading and unloading, and can more comprehensively ensure safety and reduce safety hazards.
[0033] like Figure 1 , Figure 5 As shown, several feet 5 are installed at the bottom of the hopper body 4. These feet 5 create a gap between the bottom of the hopper body 4 and the ground. The feet 5 prevent the bottom of the hopper body 4 from directly contacting the ground, reducing wear caused by friction and collisions, and extending the hopper's service life. Simultaneously, when placed on uneven ground, the feet 5 provide support and adjustment, keeping the hopper body 4 stable, preventing tilting, improving the stability of the hopper, and ensuring safety during material storage and loading / unloading.
[0034] like Figure 4 As shown, a handle 7 is installed on the side wall of the movable baffle body 3. A protrusion is formed in the middle of the handle, which is a U-shaped section 71. A support rod 72 is horizontally installed on the inner side of the U-shaped section 71. One end of the support rod 72 is welded and fixed to the outer wall of the movable baffle body 3. Both ends of the U-shaped section 71 are welded and fixed to the outer wall of the movable baffle body 3 through welding rods 73.
[0035] A handle 7 is installed on the side wall of the movable baffle body 3 to provide a point of leverage for the operator. The handle 7 facilitates manual pushing and pulling of the movable baffle body 3 by the operator to achieve its lifting and lowering operation. Compared with a handleless design, this greatly reduces the difficulty of manual operation, improves the convenience and efficiency of operation, and allows the operator to adjust the position of the movable baffle body 3 more easily and quickly to adapt to different work needs.
[0036] like Figure 1 , Figure 3 , Figure 5 As shown, a limiting baffle 621 is installed at the bottom of the guide rod 62, and the top of the guide cylinder 61 narrows to form a limiting ring 611, so that the limiting baffle 621 always slides along the inner wall of the guide cylinder 61. When the movable baffle body 3 moves to the highest height, the limiting ring 611 sits on the limiting baffle 621 and can never come out of the guide cylinder; when the movable baffle body 3 moves to the lowest height, the movable baffle body 3 sits on the limiting ring 611, and the guide cylinder 61 supports the movable baffle body 3.
[0037] A limiting baffle 621 is installed at the lower end of the guide rod 62. The limiting baffle 621 slides against the inner wall of the guide cylinder 61, limiting the sliding stroke of the guide rod 62 within the guide cylinder 61. The limiting baffle 621 prevents the guide rod 62 from detaching from the guide cylinder 61, ensuring the integrity and stability of the lifting component 6 structure. This prevents the movable baffle body 3 from losing control during lifting due to the guide rod 62 detaching, ensuring the safety and reliability of the lifting operation of the movable baffle body 3 and avoiding safety accidents caused by structural failure.
[0038] Both the hopper body 4 and the movable baffle body 3 have edge-wrapping channel steel installed on their outer edges. These channel steels wrap around the outer edges, enhancing the structural connection strength. The edge-wrapping channel steel significantly improves the overall structural strength of the hopper, effectively resisting material impact and external collisions during hoisting, reducing the risk of deformation or damage to the hopper body 4 and the movable baffle body 3 due to stress. Simultaneously, the enhanced structural stability helps ensure smooth lifting and lowering operation of the movable baffle body 3, extending the hopper's service life, reducing equipment maintenance costs, and further improving the safety and reliability of the hopper.
[0039] In use, the hopper safety device with lifting and protection function of this utility model first uses the large lifting ring 1 and the small lifting ring 2 to lift the hopper to the designated working position using hoisting equipment. During the lifting process, the large lifting ring 1 and the small lifting ring 2 can ensure the stable lifting of the hopper body 4 and the movable baffle body 3. After being lifted into place, the pads 5 at the bottom of the hopper body 4 contact the ground. The pads 5 provide support and adjustment, ensuring that the hopper body 4 remains stable even on uneven ground, while avoiding direct contact between the bottom of the hopper body 4 and the ground, thus reducing wear.
[0040] Before loading and unloading materials, the operator can adjust the position of the movable baffle body 3 using the handle 7 on the side wall of the movable baffle body 3. The operator holds the U-shaped section 71 and pushes the movable baffle body 3 upwards. At this time, the guide rod 62, connected to the outer wall of the movable baffle body 3, slides upwards within the guide cylinder 61, which is connected to the outer wall of the hopper body 4. Based on the sliding cooperation between the guide cylinder 61 and the guide rod 62, the movable baffle body 3 gradually rises. When the movable baffle body 3 rises to the appropriate height, the limiting baffle 621 at the lower part of the guide rod 62 engages with the inner wall of the guide cylinder 61 to prevent the guide rod 62 from dislodging from the guide cylinder 61.
[0041] The raised movable baffle body 3 consists of a U-shaped structure made of three steel plates, forming a protective barrier from two sides and a back. This effectively prevents materials from slipping or splashing during loading and unloading, avoiding injury to surrounding personnel and equipment and ensuring the safety of loading and unloading operations. After the material loading and unloading operation is completed, the operator can push the movable baffle body 3 downwards using the handle 7. The guide rod 62 slides downwards within the guide cylinder 61, lowering the movable baffle body 3 and reducing the overall height of the hopper for easier subsequent operations.
[0042] When it is necessary to lift a hopper containing materials, if the movable baffle body 3 is in the raised position, it can be lowered first using the handle 7 to reduce the overall center of gravity and volume of the hopper, facilitating lifting and reducing the risk of collision. Then, the large lifting ring 1 and small lifting ring 2 are used to lift the hopper using lifting equipment. During the lifting process, the edge-sealing channel steel installed on the outer sides of the hopper body 4 and the movable baffle body 3 can enhance the overall structural strength, resist material impact and external collisions, ensure the structural integrity of the hopper during lifting, prevent materials from falling, and ensure lifting safety.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
