Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer device technology, specifically a transfer device for a fertilizer palletizer. Background Technology
[0002] Transfer trolleys are lightweight transport equipment used for short-distance handling of goods, materials, or tools. They are widely used in scenarios such as fertilizer palletizing, and their core function is to improve the efficiency of short-distance handling and reduce the burden on manual labor. Their basic structure includes a metal or plastic frame, a load-bearing panel, casters, and a handle. Some models are equipped with railings, tiered partitions, or folding designs to adapt to different items. Based on load capacity, they are classified as light, medium, and heavy-duty. Heavy-duty trolleys often use thickened steel and solid tires to meet the demands of heavy industrial loads. Some models have shock absorption functions to prevent damage to fragile items during transport. This equipment requires no power drive, is easy to operate, and effectively reduces handling time and labor costs, making it a fundamental tool for achieving efficient material flow in various locations.
[0003] For example, in the utility model patent with announcement number CN222136817U, a transfer trolley includes a transfer platform. A roller conveyor belt is fixedly connected to the top of the transfer platform, and a blocking mechanism is fixedly connected to the top of the transfer platform. The roller conveyor belt is disposed inside the blocking mechanism. The blocking mechanism includes a U-shaped frame, an anti-detachment mechanism, and a positioning mechanism. Workers can lock the goods on the transfer platform by limiting the four sides of the goods. At this time, no matter which direction the goods move, the blocking mechanism can block the goods, which effectively reduces the probability of the goods slipping off the transfer trolley, thereby improving the overall safety factor of the transfer trolley.
[0004] However, when dealing with large quantities of goods, these transfer carts need to be increased in number and manpower is required to ensure that empty transfers are reduced. Thus, when there are no transfer tasks, a large number of transfer carts take up a lot of space. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a transfer device for a fertilizer palletizer, which solves the technical problem that existing devices require additional personnel and manpower to ensure reduced empty transfers when dealing with large quantities of goods, resulting in a large number of transfer trolleys taking up a lot of space when there are no transfer tasks.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a transfer device for a fertilizer palletizing machine, comprising a first transfer frame, with two slide rails inside the first transfer frame. Two guide sleeves and two positioning sleeves, communicating with the two slide rails, are fixedly installed on the front and rear walls of the outer side of the first transfer frame, respectively. Limiting screws can be screwed into the two guide sleeves and two positioning sleeves. Handrails are slidably connected to the outer walls of the two guide sleeves and two positioning sleeves. A guide groove and a set of handrail limiting holes are respectively opened on both sides of the handrail. The spacing between the set of handrail limiting holes matches the spacing between the guide sleeves and the positioning sleeves. A first transfer plate is fixedly installed on the upper wall of the first transfer frame. A second transfer plate is hinged to the first transfer plate, and an extension structure for fixing the second transfer plate is slidably connected within the two slide rails. The extension structure includes a second transfer frame and two sliders. The two sliders are respectively fixedly installed on the two sides of the second transfer frame and are slidably connected to the two slide rails. An auxiliary limiting groove for fixing the position of the second transfer plate is opened on the upper wall of the second transfer frame, and two sets of transfer limiting holes are opened on the two sides of the second transfer frame. When the second transfer frame is completely retracted into the first transfer frame, the two sets of transfer limiting holes are respectively matched with two guide screw sleeves and two positioning screw sleeves. When the limiting screw passes through the handrail limiting hole and the transfer limiting hole, the second transfer frame is restricted to the first transfer frame.
[0007] Preferably, two sets of first guardrails are fixedly installed on the upper wall of the first transfer frame, and two support rods are fixedly installed on the upper wall of the second transfer plate. Second guardrails that are slidably connected to the two sets of first guardrails are fixedly installed on the two support rods. The two sets of first guardrails protect the fertilizer on the first transfer plate. The second guardrails unfold or retract with the second transfer plate and slide in cooperation with the first guardrails to ensure that the fertilizer on the second transfer plate can also be effectively protected during the transfer process and prevent it from falling off.
[0008] Preferably, when the handrail is fixed to the guide sleeve and the positioning sleeve by the limiting screw, the rotational freedom of the handrail is restricted, forming a transfer mode; two handrail limiting rods are fixedly installed on the outer wall of the two support rods. When the handrail limiting hole on the handrail is only connected to the guide sleeve and not connected to the positioning sleeve, the handrail can rotate around the guide sleeve. The limiting screw is inserted through the handrail limiting hole into the guide sleeve and the corresponding transfer limiting hole to form a storage mode until the handrail is supported by the two handrail limiting rods.
[0009] Preferably, the lower walls of the first and second transfer frames are fixedly equipped with transfer casters, and the lower wall of the first transfer frame is also fixedly equipped with auxiliary casters. The transfer casters facilitate the overall movement of the device, and the auxiliary casters enhance the support stability of the first transfer frame. Especially when the device is extended, it can avoid deformation caused by excessive weight at the center, and ensure a smooth transfer process.
[0010] Preferably, when the two sliders slide to their maximum stroke in the two slides, the second transfer plate can be locked in the auxiliary limiting groove, at which point the two sliders cannot be reset along the two slides; this design ensures that when the second transfer frame is extended to its maximum length, the second transfer plate can be stably fixed in the auxiliary limiting groove, avoiding accidental retraction of the second transfer frame when transferring fertilizer, and ensuring the reliability of the extended structure.
[0011] Preferably, the connecting end of the guide groove is provided with an assembly chamfer; the assembly chamfer can reduce the frictional resistance when the handrail is assembled with the guide screw sleeve and the positioning screw sleeve, making it easier for the handrail to slide in smoothly or adjust its position, while avoiding damage to the connecting end due to bumps and extending the service life of the components.
[0012] Preferably, the two guide screw sleeves and the two positioning screw sleeves are respectively threaded to the two limiting screws; the threaded connection ensures that the limiting screws can be firmly inserted into the screw sleeves and the corresponding limiting holes, reliably limiting the position of the handrail and the second transfer frame, preventing loosening during transfer or storage, and improving the structural stability of the device.
[0013] Beneficial effects
[0014] This utility model provides a transfer device for a fertilizer palletizer, which has the following beneficial effects:
[0015] By sliding the second transfer frame along the first transfer frame and mutually restricting each other with the second transfer plate, the transfer capacity can be adjusted. The working mode can be adjusted according to different needs, thereby reducing the quantity of transfer carts and increasing efficiency. This solves the problem that existing transfer carts need to be increased in number and manpower to ensure that empty transfers are reduced when dealing with large quantities of goods.
[0016] By inserting the limiting screw, guide sleeve, and two positioning sleeves, and with the limiting of two sets of transfer limiting holes, the second transfer frame and handrail can be unfolded and stored. When not in use, it saves space and solves the problem that existing transfer carts take up a lot of space when there is no transfer task. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Please see Figures 1-6A transfer device for a fertilizer palletizing machine includes a first transfer frame 1. Two slide rails 2 are provided inside the first transfer frame 1. Two guide sleeves 3 and two positioning sleeves 4, which communicate with the two slide rails 2, are fixedly installed on the front and rear walls of the first transfer frame 1, respectively. Limiting screws 5 can be screwed into the two guide sleeves 3 and two positioning sleeves 4. Handrails 6 are slidably connected to the outer walls of the two guide sleeves 3 and two positioning sleeves 4. A guide groove 7 and a set of handrail limiting holes 8 are respectively provided on both sides of the handrail 6. The spacing between the set of handrail limiting holes 8 matches the spacing between the guide sleeves 3 and the positioning sleeves 4. A first transfer plate 9 is fixedly installed on the upper wall of the first transfer frame 1, and a second transfer plate 10 is hinged to the first transfer plate 9. An extension structure for fixing the second transfer plate 10 is slidably connected within the two slide rails 2. The extension structure includes a second transfer frame 11 and two sliders 12. The two sliders 12 are respectively fixedly installed on the two sides of the second transfer frame 11 and are slidably connected to the two slide rails 2. An auxiliary limiting groove 13 for fixing the position of the second transfer plate 10 is provided on the upper wall of the second transfer frame 11. Two sets of transfer limiting holes 14 are provided on the two sides of the second transfer frame 11. When the second transfer frame 11 is completely retracted into the first transfer frame 1, the two sets of transfer limiting holes 14 are matched with two guide screw sleeves 3 and two positioning screw sleeves 4 respectively. When the limiting screw 5 passes through the handrail limiting hole 8 and the transfer limiting hole 14, the second transfer frame 11 is restricted to the first transfer frame 1.
[0026] Please see Figures 1-4 Two sets of first guardrails 15 are fixedly installed on the upper wall of the first transfer frame 1, and two support rods 16 are fixedly installed on the upper wall of the second transfer plate 10. Second guardrails 17, which are slidably connected to the two sets of first guardrails 15, are fixedly installed on the two support rods 16.
[0027] Please see Figures 1-2 When the handrail 6 is fixed to the guide sleeve 3 and the positioning sleeve 4 by the limiting screw 5, the rotational freedom of the handrail 6 is restricted, forming a transfer mode; two handrail limiting rods 18 are fixedly installed on the outer wall of the two support rods 16. When the handrail limiting hole 8 on the handrail 6 is only connected to the guide sleeve 3 and not connected to the positioning sleeve 4, the handrail 6 can rotate around the guide sleeve 3. The limiting screw 5 is inserted through the handrail limiting hole 8 into the guide sleeve 3 and the corresponding transfer limiting hole 14 to form a storage mode until the handrail 6 is supported by the two handrail limiting rods 18.
[0028] Please see Figure 2 The lower walls of the first transfer frame 1 and the second transfer frame 11 are fixedly equipped with transfer casters 19, and the lower walls of the first transfer frame 1 are also fixedly equipped with auxiliary casters 20.
[0029] Please see Figure 2When the two sliders 12 slide to their maximum stroke in the two slides 2, the second transfer plate 10 can be stuck in the auxiliary limiting groove 13. At this time, the two sliders 12 cannot be reset along the two slides 2.
[0030] Please see Figure 6 The connecting end of the guide groove 7 is provided with an assembly chamfer 21. During use, the assembly chamfer 21 at the connecting end of the guide groove 7 can prevent the handrail and the screw sleeve from being bumped and damaged during storage, thus extending the life of the component.
[0031] Please see Figure 3 The two guide screw sleeves 3 and the two positioning screw sleeves 4 are respectively connected to the two limit screws 5 by threads.
[0032] Example 1, please refer to Figures 1-4 In this embodiment, the second transfer frame 11 slides along the first transfer frame 1 and mutually restricts the second transfer plate 10 to realize the transfer capacity adjustment. The working mode is adjusted according to different needs to realize the reduction of transfer vehicle and increase efficiency.
[0033] Specifically, when large-volume transfers are required, the operator first pushes the device in its storage state to the palletizer, then holds the handle 6 with both hands and rotates it clockwise around the two guide screw sleeves 3 to disengage the handle 6 from the two handrail limit bars 18, initially releasing the second transfer frame 11 from its limit. The handle 6 is then placed on the ground, and the limit locks on the transfer casters 19 of the first transfer frame 1 are opened. Next, the limit screws 5 inside the guide screw sleeves 3 are unscrewed to completely release the second transfer frame 11 from its limit. The operator then holds the second transfer frame 11 with both hands to move the two sliders. Slider 12 moves outward along the two slides 2 respectively until it slides to its maximum stroke within the slides 2. At this point, the second transfer frame 11 is fully extended, and the second transfer plate 10, which is hinged to the first transfer plate 9, is flipped upward, so that the edge of the second transfer plate 10 is engaged in the auxiliary limiting groove 13 on the upper wall of the second transfer frame 11, thus fixing the second transfer plate 10 (at this point, slider 12 cannot return to its original position along the slides 2, ensuring the stability of the extension structure). During the extension process, the support rod 16 on the second transfer plate 10 simultaneously drives the second guardrail 17 to move. The second guardrail 17 slides with the first guardrail 15 on the first transfer frame 1 to form a continuous protective barrier, preventing subsequent piled fertilizer from falling off. The handrail 6 is slid along the guide screw sleeve 3 to the positioning screw sleeve 4. At this time, the rotational freedom of the handrail 6 is restricted. The handrail limiting hole 8 corresponding to the positioning screw sleeve 4 is selected, and the limiting screw 5 is passed through the handrail limiting hole 8 and screwed into the positioning screw sleeve 4. The handrail 6 is fixed by the threaded connection to form the transfer mode (at this time, since the second transfer frame 11 is unfolded and has been limited, it is not necessary to limit the transfer). (Fixed by hole 14); release the limit lock of the transfer caster 19 on the first transfer frame 1, then the operator holds the handrail 6 with both hands and pushes the device to the palletizer working area. The transfer casters 19 on the lower wall of the first transfer frame 1 and the second transfer frame 11 roll, and the auxiliary casters 20 on the lower wall of the first transfer frame 1 enhance the support stability. The palletizer places the fertilizer on the first transfer plate 9 and the second transfer plate 10. Two sets of first guardrails 15 and second guardrails 17 surround the fertilizer to ensure that the fertilizer will not slip off the side during the transfer process.
[0034] For small-batch transportation, simply screw the limit screw 5 into the positioning screw sleeve 4 to restrict the second transfer frame 11 and the handrail 6.
[0035] Example 2: In this example, the second transfer frame 11 and the handrail 6 are unfolded and stored by inserting the limiting screw 5 with the guide screw sleeve 3 and the two positioning screw sleeves 4, and by limiting the two sets of transfer limiting holes 14, thus saving space when not in use.
[0036] Specifically, after the transfer is completed, the second transfer plate 10 is flipped and reset from the auxiliary limiting groove 13, and attached to the top of the first transfer plate 9. Then, the limiting screw 5 in the positioning sleeve 4 is unscrewed, and the second transfer frame 11 is pushed to slide along the slide rail 2 through the slider 12 until the second transfer frame 11 is completely stored in the first transfer frame 1. At this time, the transfer limiting holes 14 on both sides of the second transfer plate 10 are aligned with the guide sleeve 3 and the positioning sleeve 4, respectively. During the storage process, the second guardrail 17 is reset with the second transfer plate 10 and overlaps with the first guardrail 15 to reduce the space occupied by the protective components. The handrail 6 is slid along the guide sleeve 3 to the initial position, and the handrail limiting hole 8 and the transfer limiting hole 14 corresponding to the guide sleeve 3 are selected. The limiting screw 5 is then inserted. Screw the guide screw sleeve 3 into the corresponding transfer limit hole 14 through the handrail limiting hole 8 to fix the second transfer frame 11; rotate the handrail 6 around the guide screw sleeve 3 until the bottom of the handrail 6 contacts the handrail limiting rod 18 on the support rod 16. At this time, the handrail limiting rod 18 provides support for the handrail 6, keeping the handrail 6 in an inclined storage state to avoid shaking. At this time, the second transfer frame 11 is also further restricted by the handrail 6; after storage, the overall length of the device is greatly shortened, and the handrail 6 does not occupy extra lateral space after folding. The device can be pushed into a corner or stacked for storage, greatly saving storage space; at the same time, the assembly chamfer 21 at the connecting end of the guide groove 7 can avoid collision damage between the handrail and the screw sleeve during storage, extending the service life of the components.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
