Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically a feeding mechanism for water-soluble fertilizer production. Background Technology

[0002] Water-soluble fertilizer is a multi-element compound fertilizer that can be completely dissolved in water. It can dissolve quickly in water, making it easier for crops to absorb. Moreover, its absorption and utilization rate is relatively high. More importantly, it can be applied to facility agriculture such as sprinkler and drip irrigation to achieve integrated water and fertilizer management, thus saving water, fertilizer and labor.

[0003] In the production of water-soluble fertilizers, a dust-free feeding station is required for raw material feeding. The operating steps are as follows:

[0004] The operator places the material bag on the support and pushes it into the grid. Then, the operator manually cuts a vertical opening in the material bag and tilts and shakes the bag to empty it. The material falls into the hopper by gravity and can be connected to the conveying unit through the conveying pipe at the bottom to effectively output the material to the location. The built-in induced draft dust collector can collect the dust generated during the emptying process of the material bag.

[0005] In the above-mentioned operation, the action of cutting open the bag needs to be done manually by the operator. The operator needs to first place the bag on the support, then take the cutting tool, cut open the bag, and then put the tool away. This operation will take up a lot of the operator's energy. Therefore, in order to simplify this operation, a feeding mechanism for water-soluble fertilizer production is provided. Utility Model Content

[0006] The purpose of this utility model is to provide a feeding mechanism for water-soluble fertilizer production in order to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for water-soluble fertilizer production, comprising a dust-free feeding station consisting of a feeding station body and a feeding platform, wherein the feeding platform is fixed at the bottom end of the feeding station body at the feeding inlet, and an L-shaped inclined grid hopper is fixed at the bottom of the feeding inlet on the inner side of the feeding station body, wherein the L-shaped inclined grid hopper is used to provide inclined placement support for the feeding bag;

[0008] A bag-cutting component is provided in the area below the feeding platform and the L-shaped inclined grid hopper. The bag-cutting component is used to cut the bags placed on the top of the L-shaped inclined grid hopper.

[0009] The bag-cutting assembly includes a bag-flipping and bag-cutting unit, a bag-cutting blade, and a limiting unit;

[0010] The flipping and slicing unit operates to move and flip the slicing blade to make it contact the bag, and to cut the bag.

[0011] The limiting unit is used to limit the flipping angle of the bag-cutting blade.

[0012] As a further embodiment of this utility model: the flipping bag-splitting unit includes an electric push rod, a T-shaped seat, a crossbar, a gear, and a toothed plate;

[0013] The electric push rod is fixed to the front end of the main body of the feeding station and distributed below the feeding platform. The output end of the electric push rod passes through the inner side of the main body of the feeding station and is fixedly connected to the T-shaped seat.

[0014] The crossbar is rotatably connected to the T-shaped seat. Multiple bag-cutting blades are provided, and the multiple bag-cutting blades are evenly distributed and fixed on the outside of the crossbar along the long side. The gears are symmetrically fixed on both sides of the crossbar.

[0015] The toothed plate is fixed on both sides of the inner wall of the main body of the feeding station and close to the front end of the main body of the feeding station. When the crossbar moves to below the toothed plate, the crossbar meshes with the toothed plate, and at this time the bag-cutting blades are distributed downwards.

[0016] As a further embodiment of this utility model: the crossbars are distributed in the lower region of the L-shaped inclined grid bucket, and the horizontal height of the crossbars is lower than the horizontal height of the lowest point of the L-shaped inclined grid bucket;

[0017] When the bag-splitting blade is vertically upward, the top horizontal height of the bag-splitting blade is higher than the lowest horizontal height of the L-shaped inclined grid bucket, and the bag-splitting blade is staggered with the L-shaped railing of the L-shaped inclined grid bucket.

[0018] As a further embodiment of this utility model: the limiting unit includes a fixed limiting block, a flipping limiting block, and a torsion spring;

[0019] The T-shaped seat has a slot at one end that is larger than the outer diameter of the crossbar. The fixed limiting block is fixed to the top of the inner wall of the slot of the T-shaped seat, and the flipping limiting block is fixed to the bottom of the outer wall of the crossbar. When the crossbar rotates upward, it drives the flipping limiting block to rotate and fit against the fixed limiting block to lock the crossbar.

[0020] The torsion spring is sleeved on the outside of the crossbar, and the two ends of the torsion spring are respectively connected and fixed to the flipping limit block and the fixed limit block. When the crossbar rotates downward, it is used to twist and contract the torsion spring. The torsion spring is used to provide the flipping limit block with a thrust toward the fixed limit block.

[0021] As a further improvement of this utility model: the bottom of the crossbar does not contact the outer wall of the crossbar, so as to provide space for the installation of the torsion spring;

[0022] The torsion spring is always in a deformed and contracted state.

[0023] As a further improvement of this utility model, the electric push rod, T-shaped seat, fixed limit block, and toothed plate are arranged symmetrically in two sets with the center line of the main body of the feeding station as the center.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation

[0032] 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.

[0033] Please see Figures 1-5In this embodiment of the utility model, a feeding mechanism for water-soluble fertilizer production includes a dust-free feeding station 1 consisting of a feeding station body 101 and a feeding platform 102. The feeding platform 102 is fixed at the bottom of the feeding port of the feeding station body 101. An L-shaped inclined grid hopper 103 is fixed at the bottom of the feeding port on the inner side of the feeding station body 101. The L-shaped inclined grid hopper 103 is used to provide inclined placement support for the feeding bag.

[0034] A bag-cutting assembly 2 is provided in the area below the feeding platform 102 and the L-shaped inclined grid hopper 103. The bag-cutting assembly 2 is used to cut the bag placed on top of the L-shaped inclined grid hopper 103.

[0035] The bag-cutting assembly 2 includes a flipping bag-cutting unit, a bag-cutting blade 205, and a limiting unit;

[0036] The bag-slicing unit operates to move and flip the bag-slicing blade 205 to make it contact the bag and perform the slicing operation on the bag.

[0037] The limiting unit is used to limit the flipping angle of the bag-cutting blade 205;

[0038] The flip-over bag-splitting unit includes an electric push rod 201, a T-shaped seat 202, a crossbar 204, a gear 206, and a toothed plate 209;

[0039] The electric push rod 201 is fixed to the front end of the feeding station body 101 and distributed below the feeding platform 102. The output end of the electric push rod 201 passes through the inside of the feeding station body 101 and is fixedly connected to the T-shaped seat 202.

[0040] The crossbar 204 is rotatably connected to the T-shaped seat 202. Multiple bag-cutting blades 205 are provided. The multiple bag-cutting blades 205 are evenly distributed and fixed on the outside of the crossbar 204 along the long side of the crossbar 204. The gears 206 are symmetrically fixed on both sides of the crossbar 204.

[0041] The toothed plate 209 is fixed on both sides of the inner wall of the feeding station body 101 and close to the front end of the feeding station body 101. When the crossbar 204 moves to below the toothed plate 209, the crossbar 204 meshes with the toothed plate 209. At this time, the bag-cutting blades 205 are distributed downwards.

[0042] The limiting unit includes a fixed limiting block 203, a flipping limiting block 207, and a torsion spring 208;

[0043] One end of the T-shaped seat 202 is formed with a slot larger than the outer diameter of the crossbar 204. The fixed limiting block 203 is fixed to the top of the inner wall of the slot of the T-shaped seat 202, and the flipping limiting block 207 is fixed to the bottom of the outer wall of the crossbar 204. When the crossbar 204 rotates upward, it drives the flipping limiting block 207 to rotate and fit against the fixed limiting block 203 to realize the rotation locking of the crossbar 204.

[0044] The torsion spring 208 is sleeved on the outside of the crossbar 204, and the two ends of the torsion spring 208 are respectively connected and fixed to the flipping limit block 207 and the fixed limit block 203. When the crossbar 204 rotates downward, it is used to twist and contract the torsion spring 208. The torsion spring 208 is used to provide the flipping limit block 207 with a thrust toward the fixed limit block 203.

[0045] The bottom of the crossbar 204 does not contact the outer wall of the crossbar 204, so as to provide space for the installation of the torsion spring 208;

[0046] The torsion spring 208 is always in a deformed and contracted state.

[0047] In this embodiment: during the production of water-soluble fertilizer, the operation method for feeding materials through this dust-free feeding station 1 is as follows:

[0048] The operator moves the bag onto the loading platform 102 and pushes the bag down onto the L-shaped inclined grid hopper 103. During this process, the bag-cutting blade 205 is in its initial position and faces downwards, and will not contact the bag above the L-shaped inclined grid hopper 103. This structure can improve the safety of equipment operation.

[0049] Then, the electric push rod 201 is activated by the control button located outside the main body 101 of the feeding station. The electric push rod 201 pushes the T-shaped seat 202, the crossbar 204, the bag-cutting blade 205, and the gear 206 to move horizontally as a whole. At this time, the gear 206 rotates under the limiting action of the toothed plate 209. The gear 206 drives the crossbar 204 and the bag-cutting blade 205 to rotate upward. When the gear 206 separates from the toothed plate 209, the bag-cutting blade 205 flips upward exactly 180 degrees, so that the bag-cutting blade 205 flips from vertical downward to vertical upward (it should be noted that at this time, the blade edge of the bag-cutting blade 205 faces the front of the movement, and the back of the blade faces the rear of the movement. At this time, the top of the bag-cutting blade 205 has not yet fully protruded into the inner area of ​​the L-shaped inclined grid hopper 103, that is, it has not yet contacted the bag). At this time, the flipping limiting block 207 is attached to the fixed limiting block 203 under the torsion of the torsion spring 208.

[0050] Afterwards, the electric push rod 201 continues to operate, and its vertically upward-facing bag-cutting blade 205 moves horizontally. Since the inclined grid hopper 103 is tilted as a whole, the top of the bag-cutting blade 205 can slowly protrude into the inner area of ​​the L-shaped inclined grid hopper 103. During this process, the bag-cutting blade 205 contacts the bag to cut it. It should also be noted that during this process, the fixed limit block 203 limits the flipping limit block 207, which can keep the bag-cutting blade 205 in a stable working state.

[0051] When the bag-cutting blade 205 has completely moved past the rear end of the inclined grid bucket 103, the electric push rod 201 reverses and drives the bag-cutting blade 205 to reset. During this process, if the bag-cutting blade 205 comes into contact with the bag or material again, the bag-cutting blade 205 will flip downward under the action of resistance, so it will not cause too much tearing of the bag and generate debris. At the same time, it can reduce the resistance encountered during reset.

[0052] When the bag-cutting blade 205 moves close to the area of ​​the toothed plate 209, since the bag in this part is not cut, and the top height of the bag-cutting blade 205 is lower than the inner lower surface of the L-shaped inclined grid hopper 103, the bag-cutting blade 205 is not subjected to external thrust. The bag-cutting blade 205 will be reset to the vertical upward state under the torque of the torsion spring 208, thus ensuring the smooth meshing of the gear 206 and the toothed plate 209.

[0053] When gear 206 engages with toothed plate 209, gear 206 rotates downwards, causing crossbar 204 and bag-cutting blade 205 to rotate downwards, and causing torsion spring 208 to further twist and deform, ultimately making bag-cutting blade 205 vertically downwards.

[0054] By repeating the above operations, the automatic bag-cutting operation can be achieved, thereby effectively reducing the workload of operators (it should be noted that the dust removal structure and bottom conveying structure of the dust-free feeding station 1 are the same as the operating principle of the existing dust-free feeding stations on the market, and will not be described in detail here).

[0055] Please refer to this carefully. Figures 1-2 The crossbars 204 are distributed in the lower area of ​​the L-shaped inclined grid hopper 103, and the horizontal height of the crossbars 204 is lower than the horizontal height of the lowest point of the L-shaped inclined grid hopper 103.

[0056] When the bag-cutting blade 205 is vertically upward, the top horizontal height of the bag-cutting blade 205 is higher than the lowest horizontal height of the L-shaped inclined grid hopper 103, and the bag-cutting blade 205 and the L-shaped railing of the L-shaped inclined grid hopper 103 are staggered.

[0057] In this embodiment, this structure ensures that the movement and rotation of the crossbar 204 and the bag-cutting blade 205 will not interfere with the L-shaped inclined grid bucket 103.

[0058] Please refer to this carefully. Figures 1-3 Two sets of electric push rods 201, T-shaped seats 202, fixed limit blocks 203, and toothed plates 209 are symmetrically arranged around the center line of the main body 101 of the feeding station.

[0059] In this embodiment, this structure can make the forces on both sides of the crossbar 204 balanced, thereby ensuring the stability of the movement and rotation of the crossbar 204.

[0060] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
