Description

Technical Field

[0001] This utility model relates to the field of seeding device technology, and in particular to a seeding device for agricultural planting. Background Technology

[0002] Agriculture is a fundamental industry that supports national economic construction and development. Crop farming is one of the main components of agriculture. With the continuous advancement of science and technology, planting techniques are also constantly developing. In order to improve planting efficiency, various seeding devices have begun to appear on the market.

[0003] However, existing seeding devices, especially push-type devices with furrowing functions, usually have fixed or limited furrowing components. When not in operation, they are difficult to completely detach from the ground, resulting in high movement resistance, laborious operation, and easy wear of components. Moreover, the furrowing depth adjustment mechanism is often inconvenient to operate, has poor precision, and lacks a reliable locking function, which can easily lead to uneven sowing depth and affect the uniformity of seedling emergence and crop growth. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a seeding device for agricultural planting to solve the problems mentioned in the background art.

[0005] An agricultural planting seeding device, comprising:

[0006] trolley;

[0007] A storage and discharge mechanism, which is fixedly installed on the upper end of the trolley;

[0008] A trenching mechanism is located in front of the storage and discharge mechanism and fixed to the trolley. The trenching mechanism includes a U-shaped seat, a lifting seat, a gear and rack assembly, a rotating assembly, and a trenching block. The U-shaped seat is fixed to the trolley. The lifting seat is slidably connected to the inner side of the U-shaped seat. A T-slot is opened at the front end of the lifting seat. The gear and rack assembly is installed inside the T-slot. The rotating assembly is installed at the front end of the U-shaped seat and is connected to the gear and rack assembly. The trenching block is V-shaped and fixed to the lower end of the lifting seat.

[0009] Preferably, the trolley has a front wheel assembly at the front and a rear wheel assembly at the rear.

[0010] Preferably, the storage and discharge mechanism includes a storage hopper, a cylinder, a discharge pipe, a rotating shaft, and material plates. The storage hopper is fixed to the upper end of the trolley, and the cylinder is fixed to the lower end of the storage hopper. The upper end of the cylinder has an inlet that communicates with the storage hopper. The lower end of the cylinder has a discharge outlet. The discharge pipe is fixed to the lower end of the cylinder and communicates with the discharge outlet. The rotating shaft is rotatably connected to the center of the cylinder. The right side of the rotating shaft moves through the cylinder. Multiple material plates are uniformly fixed in a ring shape on the outer wall of the rotating shaft. The material plates are located inside the cylinder. A chain drive mechanism is connected between the right side of the rotating shaft and the right side of the front wheel assembly.

[0011] Preferably, the inner wall of the T-slot has side grooves at both ends. The gear and rack assembly includes a rack and a gear. The rack is fixed to the bottom of one of the side grooves. The gear is set in the T-slot. The left and right ends of the gear extend into the two side grooves respectively. The gear meshes with the rack.

[0012] Preferably, the rotating assembly includes a worm gear box, a worm, a knob, a shaft, and a worm gear. The worm gear box is fixed to the front end of the U-shaped seat, the worm is rotatably connected to the upper part of the worm gear box, and the right side of the worm moves through the worm gear box and is fixed to the knob.

[0013] Preferably, the shaft is located below the worm and is connected to the inside of the worm gear box by a bearing. The rear part of the shaft extends movably into the T-slot and is fixed to the gear. The worm gear is fixed outside the shaft, and the worm and the worm gear are connected by a transmission.

[0014] The beneficial effects of this utility model are as follows: When the seeding device is moved on a normal road surface, the knob is turned to drive the worm gear to rotate. Then, through the worm gear and worm wheel transmission, the shaft is driven to rotate. This shaft drives the gear to rotate, and the gear meshes with the rack to move the lifting seat upward. The lifting seat then moves the furrowing block upward. Therefore, the furrowing block does not increase the resistance of the seeding device when moving on a normal road surface. When it is necessary to sow after furrowing, the knob is reversed to move the furrowing block downward and insert it into the soil. By moving the entire seeding device, furrows can be opened before sowing, thus improving practicality. Attached Figure Description

[0022] like Figures 1-6 As shown, an agricultural planting seeding device includes:

[0023] The trolley 1 has a front wheel assembly at the front and a rear wheel assembly at the rear. By pushing the trolley 1, the trolley 1 can move using the front wheel assembly and the rear wheel assembly.

[0024] A storage and discharge mechanism 3 is fixedly installed on the upper end of a trolley 1. The storage and discharge mechanism 3 includes a storage hopper 31, a cylinder 32, a discharge pipe 33, a rotating shaft 34, and material plates 37. The storage hopper 31 is fixed to the upper end of the trolley 1, and the cylinder 32 is fixed to the lower end of the storage hopper 31. The upper end of the cylinder 32 has an inlet 35 communicating with the storage hopper 31. The lower end of the cylinder 32 has a discharge outlet 36, and the discharge pipe 33 is fixed to the lower end of the cylinder 32 and communicates with the discharge outlet 36. The rotating shaft 34 is rotatably connected to the center of the cylinder 32, and its right side movably penetrates the cylinder 32. Multiple material plates 37 are uniformly fixed in a ring shape on the outer wall of the rotating shaft 34. The material plates 37 are located within the cylinder 32. Inside 2, a chain drive mechanism 2 is connected between the right side of the rotating shaft 34 and the right side of the front wheel assembly. When the front wheel assembly moves, the chain drive mechanism 2 can drive the rotating shaft 34 to rotate synchronously. A protective cover can also be set outside the chain drive mechanism 2. The protective cover is connected to the shaft of the rotating shaft 34 and the shaft of the front wheel assembly through bearings. In this way, the protective cover can prevent soil from sticking to the outside of the chain drive mechanism 2. When the rotating shaft 34 rotates, it can drive the material plate 37 to move in a circular motion. In this way, the agricultural seeds stored in the storage hopper 31 can fall into the cylinder 32 along the inlet 35 and then fall between two adjacent material plates 37. As the agricultural seeds move to the outlet 36, they can fall into the soil from the discharge pipe 33 along the outlet 36.

[0025] A trenching mechanism 4 is located in front of the storage and discharge mechanism 3 and fixed to the trolley 1. The trenching mechanism 4 includes a U-shaped base 41, a lifting base 42, a gear and rack assembly, a rotating assembly, and a trenching block 48. The U-shaped base 41 is fixed to the trolley 1. The lifting base 42 is slidably connected to the inner side of the U-shaped base 41. A T-shaped groove 43 is opened at the front end of the lifting base 42. The gear and rack assembly is installed inside the T-shaped groove 43. The rotating assembly is installed at the front end of the U-shaped base 41 and is connected to the gear and rack assembly. The trenching block 48 is V-shaped and fixed. At the lower end of the lifting seat 42, the rotating component can be rotated to drive the gear and rack assembly, which in turn drives the lifting seat 42 to move up and down along the U-shaped seat 41. This, in turn, drives the furrowing block 48 to move up and down. When the seeding device is moved on a normal road surface, the lifting seat 42 drives the furrowing block 48 to move upward. Therefore, the furrowing block 48 will not increase the resistance of the seeding device on a normal road surface. When it is necessary to sow after furrowing, the furrowing block 48 is moved downward to insert into the soil. By moving the entire seeding device, furrows can be opened before sowing, thus improving practicality.

[0026] The T-slot 43 has side slots 44 at both ends of its inner wall. The gear and rack assembly includes a rack 45 and a gear 46. The rack 45 is fixed to the bottom of one of the side slots 44. The gear 46 is disposed in the T-slot 43, with its left and right ends extending into the two side slots 44 respectively. The gear 46 meshes with the rack 45. The rotating assembly includes a worm gear box 47, a worm 471, a knob 472, a shaft 473, and a worm gear 474. The worm gear box 47 is fixed to the front end of the U-shaped seat 41. The worm 471 is rotatably connected to the upper part of the worm gear box 47. The right side of the worm 471 moves through the worm gear box 47 and is fixed to the knob 472. The shaft 473 is located below the worm 471 and is connected to the worm gear box 47 by a bearing. The rear part of the shaft 473 moves through the T-slot 43 and is fixed to the gear 46. The worm gear 474 is fixed to the outside of the shaft 473. The worm 471 and the worm gear 474 are connected by a transmission. By rotating the knob 472 counterclockwise, the worm 471 is driven to rotate. The worm gear 471 and worm wheel 474 drive the shaft 473 to rotate. This shaft 473 then drives the gear 46 to rotate clockwise within the T-slot 43, causing the gear 46 to mesh with the rack 45 and move the rack 45 on the left upwards. The rack 45 then moves the lifting seat 42 upwards along the U-shaped seat 41, causing the lifting seat 42 to move the furrowing block 48 upwards. Therefore, the furrowing block 48 does not increase the resistance of the seeding device on normal road surfaces. When sowing is needed after furrowing, the knob 472 is turned clockwise to drive the worm gear. Rotating 471, the worm gear 471 and worm wheel 474 drive the shaft 473 to rotate. This shaft 473 then drives the gear 46 to rotate counterclockwise within the T-slot 43, causing the gear 46 to mesh with the rack 45 and move the rack 45 on the left side downwards. The rack 45 then drives the lifting seat 42 to move downwards along the U-shaped seat 41, causing the lifting seat 42 to move the furrowing block 48 downwards, allowing the furrowing block 48 to insert into the soil. By moving the entire sowing device, furrows can be created by the furrowing block 48 before sowing.
