Description

Technical Field

[0001] The utility model relates to the technical field of water-soluble fertilizer production equipment, in particular to a water-soluble fertilizer bagging device. Background Art

[0002] Water-soluble fertilizers refer to compound fertilizers containing nitrogen, phosphorus, potassium, calcium, magnesium, trace elements, amino acids, humic acid, alginic acid, etc. that can be completely dissolved in water. They are divided into two forms: solid water-soluble fertilizers and liquid water-soluble fertilizers.

[0003] When solid water-soluble fertilizers are bagged, like other solid fertilizers, it is necessary for workers to open the bag mouth manually and place it under the discharge pipe to receive the materials. When multiple discharge pipes discharge materials simultaneously, a large amount of labor is required to hold the bag, which not only increases the labor cost but also improves the labor intensity of workers.

[0004] The Chinese utility model patent with the application number CN202320571103.8 discloses a water-soluble fertilizer bagging device. This device can fix the packaging bag under the discharge pipe, eliminating the need for manual bag holding and material receiving, saving labor and reducing the labor intensity of workers, and is suitable for use during bagging. However, when using this device, it is necessary for workers to fix the position of the fixed block by tightening two adjusting nuts manually. Although the structure is relatively simple, long-term operation will still cause worker fatigue, thereby reducing work efficiency. Content of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a water-soluble fertilizer bagging device to solve the technical problem that when using the water-soluble fertilizer bagging device in the above patent, it is necessary for workers to fix the position of the fixed block by tightening two adjusting nuts manually. Although the structure is relatively simple, long-term operation will still cause worker fatigue, thereby reducing work efficiency.

[0006] The utility model provides a water-soluble fertilizer bagging device, which includes a discharge pipe, at least two screws symmetrically distributed on the outer side of the discharge pipe and rotatably connected thereto, and two support components for fitting and tightly pressing the inner side of the packaging bag and respectively screwed onto the two screws. It also includes a fixed table arranged on the outer side of the discharge pipe, a toothed ring rotatably arranged on the outer side of the discharge pipe, a gear fixedly arranged on the two screws and meshing with the toothed ring, and a driving component. The driving component is used to drive the toothed ring to rotate, so as to drive the two screws to rotate through the gear, and further drive the support components on the two screws to approach or move away from each other along the screw axis direction.

[0007] Furthermore, the driving component includes a driving gear rotatably arranged on the fixed table and a driving part for driving the driving gear to rotate; a rotating table is arranged at the bottom of the toothed ring, and the rotating table is rotatably installed on the outer sides of the fixed table and the discharge pipe and is provided with a toothed ring meshing with the driving gear.

[0008] Further, the fixed table is provided with an annular groove, and the rotating table is provided with an annular slider adapted to the annular groove.

[0009] Further, the supporting member includes a supporting block screwed to the screw rod, a bushing and a baffle plate. The bushing is sleeved on the threaded section of the screw rod, and a rotation stopping block is arranged on the inner side along the axial direction of the screw rod. The baffle plate is fixedly connected to the bushing.

[0010] Further, a rotation stopping groove is axially formed in the position of the screw rod where the threaded section is provided, and the rotation stopping block is matched with the rotation stopping groove.

[0011] Further, the threads on the threaded sections of the two screw rods have opposite helix directions.

[0012] Further, a bearing seat is arranged on the fixed table, and the screw rod is rotatably installed in the bearing seat.

[0013] Further, an installation block is arranged between the screw rod and the discharge pipe. The installation block is fixedly arranged on the outer side surface of the discharge pipe, and one end of the screw rod is rotatably arranged on the installation block.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] When the water-soluble fertilizer bagging device of the utility model is used, first, the opening of the packaging bag is manually propped open and located outside the supporting member. Then, according to the size of the bag opening, the driving member drives the toothed ring to rotate, and the toothed ring drives the gear to rotate to synchronously drive the two supporting parts to approach each other along the axial directions of their respective corresponding screw rods, so that the supporting member props up the opening of the packaging bag, realizing the automatic tight pressing of the inner side surface of the packaging bag, reducing the need for manual intervention, improving the automation degree. At the same time, the bottom of the packaging bag contacts the ground, so that the packaging bag does not hang in the air during material receiving, avoiding detachment from the supporting member. Then, after the packaging bag is tightly pressed, the material flows out of the discharge pipe and enters the packaging bag. At this time, the packaging bag can stably maintain its shape, ensuring the smooth progress of the filling process. Then, when the filling is completed, the driving member works in the reverse direction to make the supporting members move away from each other and loosen the packaging bag, completing a filling cycle.

[0016] Due to the adoption of the linkage mechanism of the screw rod and the gear in the water-soluble fertilizer bagging device of the utility model, the operator only needs to start the driving member to automatically complete the processes of tightening and loosening the packaging bag, simplifying the operation process.

[0030] The realization of the purpose, functional features and advantages of the present utility model will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0031] In order to make the purpose, technical solutions and beneficial effects of the present utility model more clear and understandable, the technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0032] In the description of the present utility model, it should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present utility model. Therefore, they do not have technical essential significance. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are only for the convenience of clear narration and are not used to limit the scope for the implementation of the present utility model. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope for the implementation of the present utility model.

[0033] As Figure 1-2 shown, an embodiment of the present utility model provides a water-soluble fertilizer bagging device, which includes a discharge pipe 10, at least two screws 20 symmetrically distributed on the outer side of the discharge pipe 10 and rotatably connected thereto, and two support members 30 for fitting and pressing against the inner side of the packaging bag and respectively screwed to the two screws 20. The distance between the discharge pipe 10 and the ground is less than the length of the packaging bag, so that the packaging bag can rely on its own weight and the support of the ground to maintain stability during the process of filling materials, preventing the packaging bag from shaking or toppling during the filling process, thereby ensuring the smooth progress of the packaging process. At the same time, four screws 20 can also be provided, which are respectively symmetrically arranged in pairs on the outer side of the discharge pipe 10. The symmetrical distribution of the four screws 20 can provide a more uniform supporting force for the packaging bag, making the packaging bag more stable when filling materials, not prone to tilting or overturning, and improving the pressing effect. Specifically, the four screws 20 can provide pressing forces in four directions, making the fitting of the inner side of the packaging bag closer to ensure that the materials will not leak during the filling process, and a spring clip can also be used to clamp the outer side of the bag mouth to further fix the packaging bag.

[0034] Based on the above solution, as Figure 1-3 shown, in the embodiment of the present utility model, the water-soluble fertilizer bagging device further includes a fixed platform 40 arranged on the outer side of the discharge pipe 10, a gear ring 50 rotatably arranged on the outer side of the discharge pipe 10, a gear 60 fixedly arranged on the two screws 20 and meshing with the gear ring 50, and a driving member 70. The driving member 70 is used to drive the gear ring 50 to rotate, so as to drive the two screws 20 to rotate through the gear 60, and further drive the support members 30 on the two screws 20 to approach or move away from each other along the axis direction of the screws 20.

[0035] In the embodiment of the present utility model, during use, first manually open the mouth of the packaging bag and place it outside the supporting member 30. Then, according to the size of the bag mouth, drive the toothed ring 50 to rotate through the driving member 70. The toothed ring 50 then drives the gear 60 to rotate to synchronously drive the two supporting parts to approach each other along the axial direction of their respective corresponding screw rods 20, so that the supporting member 30 props up the mouth of the packaging bag, realizing the automatic tight pressing of the inner side of the packaging bag, reducing the need for manual intervention, improving the degree of automation. At the same time, the bottom of the packaging bag contacts the ground, so that the packaging bag does not hang in the air during material receiving, avoiding detachment from the supporting member 30. Then, after the packaging bag is tightly pressed, the material flows out from the discharge pipe 10 and enters the packaging bag. At this time, the packaging bag can stably maintain its shape, ensuring the smooth progress of the filling process. Then, when the filling is completed, the driving member 70 works in the reverse direction to make the supporting member 30 move away from each other and relax the packaging bag, completing a filling cycle.

[0036] Specifically, as Figure 1-2 shown, in the embodiment of the present utility model, the helix directions of the threads on the threaded sections 21 of the two screw rods 20 are opposite. During the synchronous rotation of the two screw rods 20, the supporting members 30 on each of them will move away from or towards each other, that is, by rotating the screw rod 20 clockwise or counterclockwise, the distance between the two supporting members 30 can be adjusted to meet packaging bags of different calibers.

[0037] Specifically, as Figure 2 shown, in the embodiment of the present utility model, the driving member 70 includes a driving tooth 71 rotatably arranged on the fixed table 40 and a driving member 72 for driving the driving tooth 71 to rotate; a rotating table 73 is arranged at the bottom of the toothed ring 50. The rotating table 73 is rotatably installed on the outer sides of the fixed table 40 and the discharge pipe 10 and is provided with a toothed ring 731 meshing with the driving tooth 71. Among them, the driving member 72 can adopt a motor purchased from the market and can be used after corresponding installation.

[0038] Start the driving member 72, the driving member 72 drives the driving tooth 71 to start rotating. The rotation of the driving tooth 71 is transmitted to the toothed ring 50 through the meshing toothed ring 731. The toothed ring 50 starts to rotate. The rotation of the toothed ring 50 is transmitted to the screw rod 20 through the gear 60, so that the screw rod 20 starts to rotate. The rotation of the screw rod 20 drives the supporting member 30 to move along the axial direction of the screw rod 20, thereby tightly pressing the inner side of the packaging bag. After the packaging bag is tightly pressed, the material flows out from the discharge pipe 10 and enters the packaging bag. During this process, the packaging bag remains in a stable state. When the packaging bag is filled, the driving member 72 works in the reverse direction, driving the screw rod 20 to rotate in the reverse direction, so that the supporting member 30 relaxes the tight pressing on the packaging bag. After the packaging bag is relaxed, it can be removed from below the discharge pipe 10 to prepare for the filling work of the next packaging bag.

[0039] Specifically, as Figure 3-4As shown, in the embodiment of the present utility model, the fixed table 40 is provided with an annular groove 41, and the rotating table 73 is provided with an annular slider 732 adapted to the annular groove 41, making the rotation of the rotating table 73 more stable. At the same time, the friction of the direct contact surface is reduced, thereby reducing the wear rate and extending the service life.

[0040] When the driving member 72 is started, the driving gear 71 transmits power to the gear ring 50 through the toothed ring 731, and the gear ring 50 drives the rotating table 73 to rotate. During the rotation of the rotating table 73, the annular slider 732 slides in the annular groove 41 to ensure the stable rotation of the rotating table 73. The rotation of the rotating table 73 is transmitted to the screw rod 20 through the gear 60, driving the supporting member 30 on the screw rod 20 to act, realizing the tightening or loosening of the packaging bag.

[0041] Specifically, as Figure 1 and 5 shown, in the embodiment of the present utility model, the supporting member 30 includes a support block 31 screwed to the screw rod 20, a bushing 32 and a baffle 33. The bushing 32 is sleeved on the threaded section 21 of the screw rod 20, and a rotation-preventing block is arranged on the inner side along the axial direction of the screw rod 20. The baffle 33 is fixedly connected to the bushing 32. By the support block 31, the bushing 32 and the baffle 33 screwed to the screw rod 20, the inner side surface of the packaging bag can be tightened or loosened.

[0042] When it is necessary to tighten the packaging bag, the driving member 70 drives the screw rod 20 to rotate, and the rotation of the screw rod 20 causes the supporting member 30 to move along the axial direction of the screw rod 20. Since the rotation-preventing block is arranged on the inner side of the bushing 32, the bushing 32 is prevented from rotating relative to the screw rod 20, ensuring the stability during the tightening process.

[0043] Specifically, as Figure 1 and 5 shown, in the embodiment of the present utility model, a rotation-preventing groove 211 is axially formed at the position of the screw rod 20 where the threaded section 21 is provided. The rotation-preventing block and the rotation-preventing groove 211 cooperate with each other to prevent the bushing 32 from rotating with the screw rod 20 when the screw rod 20 rotates, ensuring the stability during the process of tightening the packaging bag.

[0044] Based on the above scheme, as Figure 1 shown, in the embodiment of the present utility model, a bearing seat 80 is arranged on the fixed table 40, and the screw rod 20 is rotatably installed in the bearing seat 80. The design of the bearing seat 80 makes the rotation of the screw rod 20 more stable. At the same time, the direct contact between the screw rod 20 and the fixed table 40 can be reduced, thereby reducing wear and extending the service life.

[0045] When the packaging bag needs to be tightened, the screw rod 20 is driven to rotate by the driving component 70. Since the screw rod 20 is installed in the bearing seat 80, the screw rod 20 rotates more smoothly without shaking. As the screw rod 20 rotates, the supporting component 30 gradually approaches the inner side of the packaging bag until the packaging bag is tightened and fixed. In this process, the bearing seat 80 ensures the stable rotation of the screw rod 20 and prevents any unnecessary swinging.

[0046] Specifically, Figure 1-2 As shown, in the embodiment of the utility model, a mounting block 90 is arranged between the screw 20 and the discharge pipe 10, and the mounting block 90 is fixedly arranged on the outer surface of the discharge pipe 10, and one end of the screw 20 is rotatably arranged on the mounting block 90. The mounting block 90 is fixedly arranged on the outer surface of the discharge pipe 10, and one end of the screw 20 is installed on the mounting block 90 through a bearing or other rotating connecting piece to ensure that the screw 20 can rotate freely.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
