[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0027] like Figure 1 As shown, the present invention provides a bulk material bag feeding device, including a guide rail 1, a bracket 2, a lifting device 4 and a discharge device 5.

[0028] The guide rails are laid on the ground, wherein the guide rails 1 are generally steel rails, and their upper end surfaces are not higher than the ground, which can effectively ensure that the guide rails 1 will not affect the operation of other vehicles or transportation vehicles. In other embodiments, the guide rails 1 can also be roads directly laid on the ground.

[0029] like Figure 1 As shown, the bracket 2 includes a base frame 21 and a support 22, the base frame 21 can be slidably installed on the guide rail 1, and the support 22 is vertically arranged on the base frame 21; the base frame 21 includes a frame body 211 and a displacement mechanism 212, the frame body 211 includes a front support 2111, a rear support 2112 and a support platform 2113, the front end of the support platform 2113 is connected to the front support 2111, the rear end of the support platform 2113 is connected to the rear support 2112, the support platform 2113 is horizontally arranged above the guide rail 1 and close to the guide rail 1, and the displacement mechanism 212 is installed on the front support 2111 and the rear support 2112 to drive the frame body 211 to move along the guide rail 1.

[0030] In some embodiments of the present application, the displacement mechanism 212 includes a front drive wheel installed on the front support 211, a front drive motor that drives the front drive wheel to rotate, a rear drive wheel installed on the rear support, and a rear drive motor that drives the rear drive wheel to rotate, and the front drive wheel and the rear drive wheel are both placed on the guide rail 1.

[0031] like Figure 1 As shown, the material lifting device 4 includes a lifting mechanism 41 and at least one material tray 42, see Figure 3 The lifting mechanism 41 includes a chain 411, a first driving motor 412 and two sprockets 413. The two sprockets 413 are respectively installed at the upper and lower ends of the pillar 22. The chain 411 is sleeved on the outside of the two sprockets 413 and is connected to the sprockets 413. The first driving motor 412 is used to drive the sprockets 413 to rotate.

[0032] See also Figure 5 and Figure 6 Each material tray 42 includes a base 421, a support plate 422, an elastic support member 423 and a plurality of rollers 424. The base 421 corresponding to the material tray 42 is installed on the outer side of the chain 411. The upper end surface of the base 421 has an inclined end surface. The plurality of rollers 424 are distributed in at least one row on the inclined end surface for guiding materials downward along the inclined end surface. The support plate 422 is rotatably installed on the top of the inclined end surface. A plurality of avoidance grooves 422a are formed on the support plate 422. Each avoidance groove 422a is arranged corresponding to each column of rollers 424. The elastic support member 423 is installed between the support plate 422 and the base 421 for elastically supporting the support plate 422.

[0033] Specifically, a plurality of pillars 4241 are installed on the inclined end surface of the base 421, and the plurality of pillars 4241 are distributed in at least one row on the inclined end surface. A roller 424 is rotatably installed on the upper end of the pillar 4241, and the rotation axis of the roller 424 is parallel to the inclined end surface and is perpendicular to the rotation axis of the support plate 422.

[0034] Furthermore, the elastic support member 423 is two compression springs installed between the inclined end surface and the support plate 422 , and one end of each compression spring is installed on one side of the base 421 , and the other end is installed on the corresponding side of the support plate 422 .

[0035] In order to enable the lifting device 4 to lift materials continuously, there are multiple material trays 42, and the chain 411 is provided with a plurality of mounting positions evenly spaced along its circumference. A locking ear 425 is installed on one side of each base 421 close to the chain 411, and a material tray 42 is installed at each mounting position through the locking ear 425.

[0036] In the above-mentioned embodiment, moving the material bag to the material tray 42 requires manual lifting. In order to further free up manpower and reduce the workload of the loading and unloading workers, in some embodiments of the present application, the bulk material bag feeding equipment also includes a feeding device 3, see Figure 2The feeding device 3 is used for feeding the lifting device 4, that is, conveying the material bag to the lifting device 4. Specifically, the feeding device 3 includes a first conveyor belt 31, a second conveyor belt assembly 32 and a third conveyor belt 33. The first conveyor belt 31 is horizontally installed on the support platform 2113. The second conveyor belt assembly 32 includes a support rod 321, a second conveyor belt 322, a connecting piece 323 and a moving wheel 324. The support rod 321 is tilted in front of the frame 211 and the upper end of the support rod 321 is hinged to the front support 2111. The connecting piece 323 is installed at the lower end of the support rod 321. The moving wheel 324 is installed at the end of the connecting piece 323 away from the support rod 321. The moving wheel 324 is placed on the support platform 2113. The third conveyor belt 33 is horizontally arranged at the rear end of the support rod 321. The third conveyor belt 33 and the second conveyor belt 322 are connected end to end, and the rear end of the third conveyor belt 33 is arranged toward the chain 411.

[0037] The moving wheel 324 is placed on the support platform 2113. When the frame 211 moves along the guide rail 1, the setting of the moving wheel 324 can effectively prevent the support rod 321 from being directly dragged on the support platform 2113, and can also facilitate the installation of the second conveyor belt 322.

[0038] Among them, the feeding device 3 also includes a telescopic adjustment component 34, the telescopic adjustment component 34 includes a crossbeam 341 and a telescopic mechanism 342, the crossbeam 341 is horizontally installed at the front end of the front support 2111, the horizontal height of the crossbeam 341 is not less than the front end height of the support rod 321, one end of the telescopic mechanism 342 is installed on the crossbeam 341, and the other end is installed on the support rod 321, the telescopic mechanism 342 is telescopic to drive the support rod 321 to swing.

[0039] When there are obstacles on the support platform 2113, such as spilled bulk materials or other foreign objects falling, it may be difficult for the moving wheel 324 to roll over directly or cause damage to the foreign objects. At this time, the telescopic mechanism 342 can be retracted to lift the support rod 321 together with the second conveyor belt 322 upward to achieve avoidance.

[0040] Since the first conveyor belt 31 and the second conveyor belt 322 are not on the same horizontal plane, there will be an obvious height difference at the place where the second conveyor belt 322 and the first conveyor belt 31 are connected, which will cause the material bag to be unable to smoothly reach the second conveyor belt 322 from the first conveyor belt 31. Therefore, a plurality of guide rollers 325 with successively increasing diameters are arranged at the front end of the second conveyor belt 322. Under the guidance of the guide rollers 325, the material bag reduces the height difference at the connection, thereby achieving a smooth transition between the two conveyor belts.

[0041] The unloading device 5 includes a blocking member 51, a material dropping platform 52 and a material guide plate 53. The material dropping platform 52 is installed above the base frame 21 in a liftable manner. The blocking member 51 is installed on the material dropping platform 52. The blocking member 51 is installed on one side of the chain 411 and is used to push the support plate 422 to rotate toward the side close to the base 421. The material guide plate 53 is installed obliquely between the blocking member 51 and the material dropping platform 52 and is used to guide the material bags unloaded from the material tray 42 to fall to the material dropping platform 52.

[0042] The blanking platform 52 is installed on the bottom frame 21 in a liftable manner. Specifically, a lifting motor 54 is installed on the top of the support 22, and the lifting motor 54 is connected to the blanking platform 52 through a pull rope.

[0043] In some embodiments of the present application, the mutual cooperation and promotion between the blocking member 51 and the support plate 422 is specifically that the two ends of the side of the support plate 422 away from the top of the inclined end surface are respectively rotatably installed with limit wheels 426, and the blocking member 51 includes two baffles correspondingly installed on both sides of the support plate 422 and vertically arranged, and the spacing between the two baffles is greater than the width of the base 421 and smaller than the width of the support plate 422. The baffles include an extrusion section 511, a maintaining section 512 and a release section 513 from bottom to top, and the distance the baffle extends to the side close to the material tray 42 is its thickness. The baffles satisfy that the thickness of the extrusion section 511 gradually increases from bottom to top, the thickness of the maintaining section 512 remains unchanged, and the thickness of the release section 513 gradually decreases from bottom to top, and the projection of the maintaining section 512 in the vertical direction partially overlaps with the limit wheel 426, but does not intersect with the base 421.

[0044] The limiting wheel 426 first abuts against the extrusion section 511. Since the thickness of the extrusion section 511 gradually increases from bottom to top, if the support plate 422 needs to move upward, it will inevitably press down the limiting wheel 426, thereby causing the support plate 422 to rotate toward the side close to the base 421. When the avoidance groove 422a on the support plate 422 cooperates with the roller 424, the roller 424 contacts the material bag, and the material bag slides down. At this time, the limiting wheel 426 abuts against the maintaining section 512 of the baffle bar. When the material tray 42 is unloaded, the limiting wheel 426 continues to move upward and passes through the release section 513. Since the thickness of the release section 513 gradually decreases from bottom to top, the support plate 422 is reset under the elastic force of the spring.

[0045] The bulk material bag feeding equipment provided by the present invention first moves the bracket 2 to the corresponding area according to the position of the material bag to be loaded and unloaded, and then starts the lifting motor 54 according to the height of the material to be unloaded, so that the material drop platform 52 is lifted and lowered to a suitable height, and then starts the three conveyor belts and the first drive motor 412. Then the staff sequentially places the material bag containing bulk material on the front end of the first conveyor belt 31. Driven by the first conveyor belt 31, the material bag moves to the rear end and reaches the second conveyor belt 322 through the guide roller 325. After the material bag moves to the top along the second conveyor belt 322, it reaches the third conveyor belt 33. Since the rear end of the third conveyor belt 33 is arranged toward the chain 411, the first drive motor 412 drives the sprocket 413 to rotate, and the material tray 42 performs a cyclic reciprocating motion with the chain. The material bag transported to the third conveyor belt 33 falls on the support plate 422 of the material tray 42. During the upward movement of the material tray 42, the blocking member 51 cooperates with the blocking member 51 to produce the unloading action of the above-mentioned contact process, and the material bags on the material tray 42 smoothly reach the drop platform 52. In actual production, an opening that can be opened and closed can be formed at the bottom of the drop platform 52. When the opening is closed, the material bags are piled up on the drop platform, and when the opening is opened, the material bags fall from the opening. The opening of the drop platform can be set above the cargo hold deck of the truck or above the bottom of a high-rise warehouse according to actual usage, or it can be set above the material bags to be stacked; since the bulk material bag feeding equipment in the present application does not require manual participation during the unloading process, and workers do not need to stand at a height to pick up materials, there is no safety risk of people falling from a height, and the work of placing the material bags directly on the first conveyor belt 31 set close to the ground is relatively simple and efficient, which greatly saves the manpower of workers in carrying material bags.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
