Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural machinery technology, and in particular relates to a fertilization and ditching operation device. Background Technology
[0002] The function of a fertilizer furrow opener is to create furrows, guide fertilizer into them, and cover the fertilizer with soil. The quality of furrow opening has a significant impact on the effectiveness of fertilization and crop yield. When fertilizing crops, different fertilizer furrow openers should be selected based on the agronomic requirements of the crop, the surface mulch, and soil conditions. Furrow openers can be divided into two main categories according to their entry angle: acute-angle furrow openers and obtuse-angle furrow openers. Acute-angle furrow openers have better entry ability but poorer passing ability; obtuse-angle furrow openers have poorer entry ability but better passing ability. Especially when soil moisture is poor and soil compaction is high, the entry effect of obtuse-angle furrow openers is less than ideal. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] Example 1: As Figures 1-5 As shown, this utility model discloses a fertilization and trenching device, including a shovel handle 1, a connecting plate 2, a fertilization trenching shovel 3, and a fertilizer discharge pipe 5. The shovel handle 1 is connected to the frame through an installation adjustment hole 5. The lower end of the shovel handle 1 is provided with a connecting plate 2, which is connected to the top of the fertilization trenching shovel 3 through a safety pin 6 and a hinge pin 7. The rear end face 18 of the fertilization trenching shovel 3 is connected to the fertilizer discharge pipe 5 through a fertilizer discharge pipe connecting bolt 4. The working side of the shovel body of the fertilization trenching shovel 3 has a main cutting edge 14 and a secondary cutting edge 15. The main cutting edge 14 has a concave arc structure, and the secondary cutting edge 15 is located below the end of the main cutting edge 14 and is perpendicular to the horizontal plane, which facilitates the fertilization trenching shovel entering the soil and reduces the entanglement of straw and weeds, thereby improving the soil entry performance of the fertilization trenching shovel.
[0023] The shovel handle 1 has a rectangular cross-section and is provided with multiple equally spaced installation adjustment holes 8 to facilitate adjustment of the installation height.
[0024] like Figure 2 , Figure 3 As shown, the connecting plate 2 includes a horizontal plate 9, a left plate 10, and a right plate 11. One end of the left plate 10 and the right plate 11 are connected by the horizontal plate 9, and the other end has a fork-shaped structure. The lower ends of the left plate 10 and the right plate 11 are provided with connecting plate safety pin holes 12 and connecting plate hinge pin holes 13. The angle α between the center line of the connecting plate safety pin holes 12 and connecting plate hinge pin holes 13 of the left plate 10 or the right plate 11 and the horizontal plane is 10°.

The upper pipe 23 has a circular cross-section structure and is used to connect the fertilizer box. The lower pipe 24 has a rectangular cross-section structure. The bottom of the lower pipe 24 is a sloping fertilizer discharge port. On the longer side of the lower pipe 24, there is a fertilizer discharge pipe connecting plate 25 that is connected to the fertilizer discharge pipe mounting rectangular groove 17 on both sides of the shovel body 22.
[0028] After installation, the two sides of the fertilizer discharge pipe 5 are flush with the two sides of the shovel body 22.
[0029] When the fertilizer trenching shovel 3 encounters significant resistance or obstacles during operation, the safety pin 6 of the fertilizer trenching shovel is sheared, and the fertilizer trenching shovel 3 rotates backward around the hinge pin 7 to prevent damage to the fertilizer trenching shovel.
