Description

Technical Field

[0001] This utility model relates to the field of fertilizer applicator technology, and in particular to a fertilizer anti-corrosion cover for fertilizer applicators. Background Technology

[0002] Fertilizer applicators are key pieces of equipment widely used in modern agricultural production, delivering chemical fertilizers to fields via pipelines. However, chemical fertilizers are generally highly corrosive, and long-term use will cause continuous chemical corrosion to the metal discharge pipes of the fertilizer applicator. This not only shortens the service life of the pipes but also causes fertilizer leakage due to pipe rust and perforation, affecting the accuracy of fertilization and polluting the environment.

[0003] To address this issue, the industry typically employs a solution of installing a removable anti-corrosion cover or liner on the inner wall of the discharge pipe. This method effectively isolates the fertilizer from direct contact with the metal pipe wall, significantly slowing down the corrosion process. However, this also introduces new operational requirements: to ensure long-term protection, the internal cover needs to be periodically disassembled, cleaned, and even replaced.

[0004] When performing maintenance on the protective cover, the discharge pipe must first be securely fixed. Current technologies often use simple manual clamps or bolt-type fixtures for this purpose. These devices rely entirely on manual tightening and loosening, which is time-consuming and labor-intensive, especially in situations requiring frequent maintenance, significantly reducing work efficiency.

[0005] More importantly, the installation positions of these traditional fixing devices are usually fixed and lack adjustability. When the protective cover used exceeds the length of the discharge pipe due to different specifications or installation errors, the fixing clamps cannot be moved to a more suitable position to support and clamp the discharge pipe, resulting in poor fixing effect or even failure to fix effectively. This structural rigidity makes the existing devices have poor versatility and adaptability to different scenarios, and cannot flexibly cope with various situations that arise in actual operation.

[0006] Therefore, this utility model proposes a fertilizer anti-corrosion cover for fertilizer applicators to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a fertilizer anti-corrosion cover for fertilizer applicators, aiming to improve the problems of cumbersome operation, low efficiency, fixed position, and poor versatility of the fertilizer anti-corrosion cover for fertilizer applicators in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a fertilizer anti-corrosion cover for a fertilizer applicator, comprising a discharge pipe, a protective cover disposed on the inner wall of the discharge pipe, and a support plate for bearing load; it also includes a fixing component and a telescopic mechanism.

[0009] The fixing assembly is mounted on the receiving plate. The fixing assembly includes a motor, at least two grippers for clamping the discharge tube, and a transmission mechanism connecting the motor and the grippers.

[0010] The telescopic mechanism includes an electrically controlled drive unit and a displacement transmission mechanism connected between the electrically controlled drive unit and the fixed component. The displacement transmission mechanism is used to transmit the output displacement of the electrically controlled drive unit to the fixed component. Through the structural combination of the motor-driven transmission mechanism and the electrically controlled displacement transmission mechanism, the automation of the discharge tube clamping action and the precise adjustment of the clamping position are realized.

[0011] Preferably, the transmission mechanism includes a connector connected to the motor, a first gear and a second gear, two rotating plates fixedly connected to the first gear and the second gear respectively, and two first connecting rods; the connector meshes with the first gear and the second gear simultaneously, and one end of each first connecting rod is rotatably connected to the corresponding rotating plate, and the other end is rotatably connected to a corresponding gripper.

[0012] Preferably, the two grippers, the two rotating plates, and the two first connecting rods are arranged symmetrically with respect to the plane passing through the axis of the discharge pipe.

[0013] Preferably, the connecting member is a worm gear, and the first gear and the second gear are worm wheels arranged in parallel to each other.

[0014] Preferably, the electronically controlled drive unit includes an electric push rod and a controller for controlling the extension or retraction of the electric push rod, wherein the base end of the electric push rod is fixed to the receiving plate.

[0015] Preferably, the displacement transmission mechanism includes a fixed plate, a rotating shaft, and a second connecting rod; the fixed assembly is mounted on the fixed plate, the rotating shaft is disposed on the receiving plate, one end of the second connecting rod is connected to the push rod end of the electric push rod, the other end is hinged to the fixed plate, and the middle part of the second connecting rod is rotatably connected around the rotating shaft.

[0016] Preferably, a connecting ring is fixedly connected to the outer wall of the discharge pipe, and the protective cover is detachably connected to the connecting ring.

[0017] Preferably, the motor is sleeved on the outer wall of the connector.

[0018] This utility model has the following beneficial effects: 1. In this utility model, a fixing component is first set up by a motor-driven connecting member, which meshes with the first gear and the second gear. The gear then drives the gripper to open and close synchronously through the rotating plate and the first connecting rod. This solves the problem that the fixing of the discharge pipe in the prior art usually relies on manual operation, which is cumbersome, uneven clamping force, and low efficiency. It achieves the technical effect of automated clamping action, uniform and reliable clamping force, and convenient and fast operation.

[0019] 2. In this utility model, by setting up a telescopic mechanism in which the controller drives the electric push rod, and the electric push rod then drives the entire fixed assembly to move axially along the discharge pipe through the lever action of the second connecting rod and the rotating shaft, the problem of the fixed position of the clamping device in the prior art, which cannot adapt to the situation where the protective cover of different lengths extends out of the discharge pipe, resulting in poor versatility and weak adaptability, is solved. The present invention achieves the technical effect of being able to flexibly adjust the position of the clamping point and accurately adapt to the protective cover of different lengths, greatly improving the versatility and scene adaptability of the device.

Detailed Implementation

[0022] 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.

[0023] Reference Figures 1-4This utility model provides an embodiment of a fertilizer anti-corrosion cover for a fertilizer applicator, which aims to solve the problems in the prior art where the fertilizer applicator's discharge pipe has a short service life due to fertilizer corrosion, and the replacement and fixing of its internal protective structure is complicated and has poor adaptability.

[0024] The fertilizer anti-corrosion cover for the fertilizer applicator includes a support plate 4 for bearing, a discharge pipe 1 is set on the support plate 4, a replaceable protective cover 3 is provided on the inner wall of the discharge pipe 1, and a connecting ring 2 is fixedly connected to the outer wall of the discharge pipe 1. The protective cover 3 is detachably connected to the discharge pipe 1 through the connecting ring 2.

[0025] In order to achieve automated clamping and position adaptation of the discharge pipe 1, the fertilizer anti-corrosion cover for the fertilizer applicator also includes a fixing component 5 and a telescopic mechanism 6 installed on the receiving plate 4. The telescopic mechanism 6 is connected between the receiving plate 4 and the fixing component 5 and is used to drive the fixing component 5 to move as a whole. The fixing component 5 is used to selectively clamp or loosen the discharge pipe 1.

[0026] Specifically, the fixing component 5 includes a motor 501, at least two grippers 507, and a transmission mechanism connected between the motor 501 and the grippers 507. The motor 501 serves as a power source and drives the transmission mechanism to ultimately convert the rotational motion into the synchronous opening and closing action of the grippers 507, thereby achieving reliable clamping and release of the outer wall of the discharge pipe 1.

[0027] The telescopic mechanism 6 includes an electronically controlled drive unit and a displacement transmission mechanism. The electronically controlled drive unit is used to output precise linear displacement, while the displacement transmission mechanism is connected between the electronically controlled drive unit and the fixed assembly 5. It is used to transmit the displacement generated by the electronically controlled drive unit to the entire fixed assembly 5, so that the fixed assembly 5 can adjust its position along the axial direction of the discharge pipe 1 according to the different lengths of the protective cover 3 extending out of the discharge pipe 1, so as to achieve precise positioning and clamping.

[0028] The transmission mechanism of the fixed component 5 includes a connector 502, a first gear 503, a second gear 504, two rotating plates 505, and two first connecting rods 506. The motor 501 is sleeved on the outer wall of the connector 502 and is used to drive the connector 502 to rotate, serving as the power input for the entire transmission mechanism.

[0029] In this embodiment, the connector 502 is a worm gear, while the first gear 503 and the second gear 504 are worm wheels arranged in parallel to each other. The connector 502 meshes with the external teeth of the first gear 503 and the second gear 504 at the same time. This transmission and engagement method enables the first gear 503 and the second gear 504 to rotate synchronously in opposite directions when the motor 501 drives the connector 502 to rotate, and has a self-locking function, which improves the reliability of clamping.

[0030] The two grippers 507, two rotating plates 505, and two first connecting rods 506 of the fixed assembly 5 are arranged symmetrically with respect to the plane passing through the axis of the discharge pipe 1. The two rotating plates 505 are fixedly connected to the output ends of the first gear 503 and the second gear 504, respectively. One end of each first connecting rod 506 is rotatably connected to the corresponding rotating plate 505, and the other end is rotatably connected to the corresponding gripper 507.

[0031] During operation, the connecting piece 502 driven by the motor 501 drives the first gear 503 and the second gear 504 to rotate synchronously in opposite directions. This, in turn, drives the two rotating plates 505 to rotate synchronously in opposite directions through a fixed connection. Finally, through the lever structure of the first connecting rod 506, the rotational motion of the rotating plate 505 is precisely converted into the linear reciprocating motion of the two grippers 507 synchronously retracting inward or opening outward, thereby achieving stable and uniform clamping and releasing action on the discharge pipe 1.

[0032] The electric drive unit of the telescopic mechanism 6 includes an electric push rod 601 and a controller 602 for issuing telescopic commands to the electric push rod 601. The base end of the electric push rod 601 is fixed on the receiving plate 4 to ensure stable support during operation.

[0033] Its displacement transmission mechanism includes a fixed plate 603, a rotating shaft 604, and a second connecting rod 605. The entire fixed assembly 5 is mounted on the fixed plate 603 and moves synchronously with the fixed plate 603. The rotating shaft 604 is set on the receiving plate 4 as a lever fulcrum. One end of the second connecting rod 605 is connected to the push rod end of the electric push rod 601, and the other end is hinged to the fixed plate 603. The middle part of the second connecting rod 605 is rotatably connected around the rotating shaft 604. This lever-type connection structure can effectively convert the linear motion output by the electric push rod 601 into a smooth translational motion of the fixed plate 603.

[0034] Working principle: When it is necessary to clamp and fix the discharge pipe 1, start the motor 501. The motor 501 drives the connecting piece 502 sleeved on the outside to rotate. The connecting piece 502 drives the first gear 503 and the second gear 504 to rotate in opposite directions through meshing transmission. Since the two rotating plates 505 are fixedly connected to the first gear 503 and the second gear 504 respectively, the rotation of the rotating plates 505 drives the two grippers 507 through the rotating first connecting rod 506 to achieve synchronous closing action, thereby firmly clamping the discharge pipe 1. When the motor 501 is driven in the opposite direction, the grippers 507 open synchronously, releasing the discharge pipe 1, which facilitates the cleaning or replacement of the protective cover 3.

[0035] When the length of the protective cover 3 does not match the discharge pipe 1 and the clamping position of the fixing component 5 needs to be adjusted, the controller 602 drives the electric push rod 601 to extend or retract. The push rod end of the electric push rod 601 pushes one end of the second connecting rod 605 connected thereto. The second connecting rod 605 rotates around the rotating shaft 604 set on the receiving plate 4, and its other end drives the hinged fixing plate 603 to translate. Since the entire fixing component 5 is installed on the fixing plate 603, the linear adjustment of the overall position of the fixing component 5 is realized to adapt to different working conditions and ensure effective fixing of the discharge pipe 1.
