Description

Technical Field

[0001] This utility model relates to the field of rice planting technology, and in particular to a device for uniformly spreading fertilizer in rice planting. Background Technology

[0002] Rice fertilizer uniform spreading equipment is a specialized device used in rice cultivation to evenly spread fertilizer in farmland. It typically features a fertilizer storage structure and is equipped with a flow regulation component to precisely control the fertilizer output. Through rotating discs, distribution plates, and other components, the fertilizer is evenly dispersed and spread across the field, ensuring a balanced supply of nutrients for rice growth and improving planting efficiency and rice yield.

[0003] However, existing fertilizer application equipment for rice cultivation still has significant shortcomings: Regarding fertilizer replenishment, manual refilling is required after each application, a process that is not only cumbersome but also prone to disrupting normal operations. In large-scale rice cultivation, frequent shutdowns for refilling waste considerable time, leading to low overall equipment efficiency and failing to meet the timeliness requirements of agricultural production. In terms of flow rate regulation, existing equipment largely relies on manual adjustment of flow restrictors based on operator experience. However, differences in experience and operating habits among operators, coupled with a lack of a unified and standardized adjustment mechanism, make it difficult to accurately control the fertilizer application flow rate. This results in uneven fertilizer distribution in the field; excessive fertilizer in some areas may cause seedling burn, while insufficient fertilizer in others negatively impacts rice growth, ultimately reducing rice yield and quality and affecting planting profits.

[0004] In response to this technical problem, this application proposes a fertilizer uniform spreading device for rice cultivation. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as cumbersome and easily interrupted feeding, low efficiency, and insufficient uniformity of fertilizer application due to reliance on experience and lack of standards for flow regulation. This invention proposes a uniform fertilizer application device for rice cultivation. This device enables rapid replacement of the storage bin and immediate application, shortening downtime for feeding. Furthermore, by utilizing the flow-limiting plate positioning groove and positioning block in conjunction, it forms standardized flow levels and uniformly dispersed application, improving efficiency and uniformity.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A uniform fertilizer spreading device for rice cultivation includes a mounting base, a back plate fixedly connected to the rear side of the mounting base, an installation groove on the front side of the back plate, a storage box detachably connected to the inner wall of the installation groove, a fixing seat fixedly connected to the bottom front side of the outer wall of the storage box, clamping plates slidably connected to the left and right sides of the inner wall of the fixing seat, the front ends of the clamping plates on adjacent sides being connected by a tension spring, a push plate slidably connected to the middle of the inner wall of the fixing seat, the clamping plates being connected to the mounting base via a connecting assembly, a discharge port at the bottom of the storage box, a baffle slidably connected to the bottom left side of the outer wall of the storage box, a material inlet at the top of the mounting base, a flow limiting plate slidably connected to the right side of the outer wall of the mounting base, and a turntable provided on the inner wall of the mounting base.

[0008] Furthermore, the top of the flow limiting plate is provided with multiple positioning slots, and the bottom of the right side of the outer wall of the mounting base is fixedly connected to a limiting seat, which is connected to the positioning slots through a positioning component.

[0009] Furthermore, the connecting component includes a locking block and a connecting block. The locking block is fixedly connected to the bottom end of the clamping plate on the side adjacent to it, and the connecting block is fixedly connected to the top end of the front side of the outer wall of the mounting base. The connecting block and the locking block are detachably connected.

[0010] Furthermore, the positioning component includes a spring, which is disposed on the bottom side of the inner wall of the limiting seat, and a positioning block is fixedly connected to the top of the spring. The positioning block is detachably connected to the positioning groove.

[0011] Furthermore, the push plate is in the shape of an inverted pentagon, and the top of the clamping plate is in the shape of a trapezoid.

[0012] Furthermore, the clamps are installed in a relatively opposite direction.

[0013] Furthermore, a top cover is rotatably connected to the top of the storage box, and a shoulder strap is provided on the rear side of the back plate.

[0014] Furthermore, a diverter plate is fixedly connected to the top of the turntable.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the detachable design of the mounting groove and the storage box, combined with the linkage structure of clamping plate and tension spring, allows the storage box to be quickly slid into the pre-stored fertilizer storage box when the fertilizer in the storage box is used up. The pressing plate causes the clamping plate to slide open relative to each other. After aligning with the connecting block, the tension spring automatically engages and fixes the box, eliminating the need for manual material pouring and achieving "immediate replacement and sowing". This greatly shortens the downtime for material replenishment and improves work efficiency.

[0017] 2. In this utility model, the flow limiting plate can be precisely pulled to the corresponding fixed position by multiple positioning grooves on the top of the flow limiting plate and the spring and positioning block in the limiting seat. The positioning block is then inserted into the positioning groove under the action of the spring, forming a standardized flow level and avoiding the error of manual experience adjustment. Combined with the micro motor drive at the bottom of the turntable and the rotation and dispersion of the flow dividing plate, it ensures that the fertilizer is evenly spread after falling through the feed inlet, which significantly improves the uniformity of spreading.

[0025] 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.

[0026] Reference Figures 2-4An embodiment of this utility model provides a uniform fertilizer spreading device for rice planting, including a mounting base 1, a back plate 6 fixedly connected to the rear side of the mounting base 1, a mounting groove 7 opened on the front side of the back plate 6, a storage box 8 detachably connected to the inner wall of the mounting groove 7, a fixing seat 9 fixedly connected to the bottom front side of the outer wall of the storage box 8, a clamping plate 10 slidably connected to the left and right sides of the inner wall of the fixing seat 9, the front ends of the clamping plates 10 on the adjacent side are connected by a tension spring 11, a push plate 16 slidably connected to the middle of the inner wall of the fixing seat 9, the clamping plate 10 is connected to the mounting base 1 through a connecting component 12, a discharge port 15 is opened at the bottom of the storage box 8, a baffle 17 is slidably connected to the bottom left side of the outer wall of the storage box 8, a material passage port 4 is opened at the top of the mounting base 1, a flow limiting plate 5 is slidably connected to the right side of the outer wall of the mounting base 1, and a turntable 2 is provided on the inner wall of the mounting base 1.

[0027] Specifically, the back plate 6 fixed to the rear of the mounting base 1 has an installation groove 7 on the front, which enables the detachable connection of the storage box 8. It works in conjunction with the clamping plate 10, which is set opposite to the fixed base 9 and has a trapezoidal top. Through the connection of the tension spring 11 and the detachable engagement of the locking block 1201 and the connecting block 1202 in the connecting assembly 12, the storage box 8 with pre-stored fertilizer can be quickly slid into the installation groove 7 after the fertilizer in the current storage box 8 has been spread. The clamping plate 10 is slid relative to each other by pressing down the inverted pentagonal push plate 16. After the locking block 1201 is aligned with the connecting block 1202, the contraction force of the tension spring 11 makes the locking block 1201 lock into the connecting block 1202 to achieve fixation. There is no need for frequent manual dumping, which greatly improves the feeding efficiency.

[0028] Reference Figure 1 , Figure 4 and Figure 5 The flow-limiting plate 5 has multiple positioning slots 19 on its top. A limiting seat 18 is fixedly connected to the bottom right side of the outer wall of the mounting base 1. The limiting seat 18 is connected to the positioning slots 19 via a positioning assembly 20. The connecting assembly 12 includes a locking block 1201 and a connecting block 1202. The locking block 1201 is fixedly connected to the bottom end of the clamping plate 10 on the side closest to it. The connecting block 1202 is fixedly connected to the top end of the front side of the outer wall of the mounting base 1. The connecting block 1202 and the locking block 1201 are detachably connected. Component 20 includes a spring 2001, which is disposed on the bottom side of the inner wall of the limiting seat 18. A positioning block 2002 is fixedly connected to the top of the spring 2001, and the positioning block 2002 is detachably connected to the positioning groove 19. The push plate 16 is in the shape of an inverted pentagon, and the top of the clamping plate 10 is in the shape of a trapezoid. The clamping plates 10 are installed in opposite directions. A top cover 13 is rotatably connected to the top of the storage box 8, and a shoulder strap 14 is provided on the rear side of the back plate 6. A diverter plate 3 is fixedly connected to the top of the turntable 2.

[0029] Specifically, the shoulder strap 14 on the back of the back plate 6 facilitates carrying the equipment, and the top cover 13 is rotatably connected to the storage box 8 for easy pre-filling of fertilizer. The flow limiting plate 5 on the right side of the outer wall of the mounting base 1 has multiple positioning slots 19. With the positioning block 2002 connected to the spring 2001 in the limiting seat 18, the flow limiting plate 5 can be pulled to the corresponding fixed position according to the required spreading flow. The positioning block 2002 is then inserted into the positioning slot 19 under the action of the spring 2001, realizing standardized flow adjustment and avoiding the problem of insufficient uniformity caused by relying on manual experience. The top of the turntable 2 on the inner wall of the mounting base 1 is fixed with a diverter plate 3. The bottom of the turntable 2 is equipped with a micro motor to drive the rotation. The fertilizer falling from the outlet 15 of the storage box 8 can be transported to the turntable 2 through the feed inlet 4. The fertilizer is evenly dispersed and spread by the rotating diverter plate 3, ensuring the uniformity of fertilizer spreading.

[0030] Working principle: During use, the equipment is carried by shoulder strap 14. Fertilizer is pre-filled into storage bin 8 and the top cover 13 is closed. According to the target sowing flow rate, the flow limiting plate 5 is pulled out, so that the positioning block 2002 is locked into the corresponding positioning groove 19 under the action of spring 2001 to fix the position of the flow limiting plate 5. The micro motor is started to drive the turntable 2 and the diverter plate 3 to rotate. The fertilizer in storage bin 8 falls through the outlet 15 and enters the mounting base 1 through the feed inlet 4 under the control of baffle 17. It falls on the rotating diverter plate 3 and is evenly dispersed by the diverter plate 3 to be sown to the rice planting area. When the current fertilizer in storage bin 8 is... When the material is used up, there is no need to stop the machine. Simply remove the empty storage box 8 from the mounting slot 7, slide the storage box 8 pre-filled with fertilizer into the mounting slot 7, press down the push plate 16 to make the clamping plate 10 at the top of the trapezoidal slide open relative to each other, and after the locking block 1201 is aligned with the connecting block 1202 at the top front side of the mounting base 1, release the push plate 16. The tension spring 11 contracts and drives the clamping plate 10 to reset, so that the locking block 1201 is locked into the connecting block 1202 to fix the storage box 8. At the same time, the push plate 16 pushes the fertilizer in the storage box 8 to move towards the discharge port 15 to continuously supply fertilizer and achieve uninterrupted, efficient and uniform spreading operation.
