Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural planting, in particular to a soil loosening device for agricultural planting. Background Art

[0002] Before planting in cultivated land, it is usually necessary to loosen the soil with a loosening device because the soil becomes hard and compacted. For example, the utility model patent with application number CN202420132154.5 discloses a loosening device for improving saline-alkali soil, which consists of a plow and a loosening frame. The plow is installed on a mounting frame. When loosening the soil, the plow is inserted into the soil, and then the loosening frame can be pulled by a tractor to loosen the soil. However, the mounting frame of the device has a fixed length. Because the shape of cultivated land in some areas is irregular, if the mounting frame is long, it is impossible to enter the narrower area of ​​the cultivated land for loosening. If the mounting frame is short, it will affect the loosening efficiency in the wider cultivated land area, so further improvement is needed. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] The present application embodiment provides a soil loosening device for agricultural planting, such as Figure 1-Figure 4 As shown, it includes a first mounting frame 1, a second mounting frame 2, a plow 3, etc.

[0023] Specifically, a pair of first connecting plates 101 are provided at one end of the top of the first mounting frame 1, the second mounting frame 2 is provided at one end of the first mounting frame 1, and a pair of second connecting plates 202 are provided at one end of the top of the second mounting frame 2 close to the first mounting frame 1, the second connecting plates 202 are located between the pair of first connecting plates 101, and the pair of second connecting plates 202 are rotatably connected to the pair of first connecting plates 101 through two connecting shafts 203, respectively, so that the second mounting frame 2 can be rotated to the top of the first mounting frame 1, and the plow blades 3 are divided into two groups, which are respectively arranged in the first mounting frame 1 and the second mounting frame 2. Specifically, each group of plow blades 3 can be arranged in a rectangular array.

[0024] In actual use, the device is connected to a tractor. When the cultivated land is wide, the second mounting frame 2 is lowered so that the plow blades 3 in the first mounting frame 1 and the second mounting frame 2 are inserted into the cultivated land. Then, the device is pulled by the tractor to loosen the soil, thereby improving the loosening efficiency. When the cultivated land to be loosened is narrow, the first mounting frame 1 or the second mounting frame 2 is rotated upward so that the two are folded, thereby reducing the overall length of the device for loosening the soil, thereby improving the practicality of the loosening device.

[0025] Preferably, see Figure 1 , Figure 3A first slide rail 4 is provided on one side of the first mounting frame 1 along its length direction, and a second slide rail 5 is provided on one side of the first mounting frame 1 along its length direction. A connecting buckle 6 is slidably connected to the first slide rail 4 for connecting with the tractor. When the second mounting frame 2 is rotated downward to be parallel to the first mounting frame 1, the first slide rail 4 is connected with the second slide rail 5. Specifically, the first slide rail 4 can be arranged to extend from the middle of the first mounting frame 1 to the outside of one end of the first mounting frame 1 close to the second mounting frame 2, and the second slide rail 5 can be arranged to extend inward from the outside of one end of the second mounting frame 2 close to the first mounting frame 1. When the first mounting frame 1 and the second mounting frame 2 are folded, the connecting buckle 6 can be slid to the inward end of the first slide rail 4, so that the mounting buckle is in the middle of one side of the first mounting frame 1. After the tractor is connected with the mounting buckle, the device as a whole can be pulled from the middle of one side of the first mounting frame 1. When the first mounting frame 1 and the second mounting frame 2 are opened, the connecting buckle 6 can be slid to the intersection of the first slide rail 4 and the second slide rail 5, so that the first mounting frame 1 and the second mounting frame 2 cannot rotate. When the tractor is connected to the mounting buckle, the device can be pulled from the middle of the entire device to improve the stability of the first mounting frame 1 and the second mounting frame 2 during movement when loosening the soil.

[0026] For more details, see Figure 4 , two first connection holes 401 and one second connection hole 402 are provided on the first slide rail 4, a third connection hole 501 is provided on the second slide rail 5, and a pair of fourth connection holes 601 matching the two first connection holes 401 are provided on the connection buckle 6. When the connection buckle 6 slides to the middle of one side of the first mounting frame 1, the two first connection holes 401 and the pair of fourth connection holes 601 are connected. When the first mounting frame 1 and the second mounting frame 2 are folded, the mounting buckle can be fixed to the two first connection holes 401 by pins or screws. When the connection buckle 6 slides to the bottom of the connecting shaft 203, the pair of fourth connection holes 601 are connected to the second connection hole 402 and the third connection hole 501 respectively. When the first mounting frame 1 and the second mounting frame 2 are opened, the mounting buckle can be fixed to the two second connection holes 402 and the third connection hole 501 by pins or screws.

[0027] For details, see Figure 1 A third pin hole 102 is provided at one end of the first mounting frame 1 facing the second mounting frame 2, and a fourth pin hole 103 matching the third pin hole 102 is provided at one end of the second mounting frame 2 facing the first mounting frame 1. When the second mounting frame 2 is rotated downward to be parallel to the first mounting frame 1, the third pin hole 102 and the fourth pin hole 103 have the same axial direction. When the first mounting frame 1 and the second mounting frame 2 are opened, a fixing pin can be inserted into the third pin hole 102 and the fourth pin hole 103 to further prevent the first mounting frame 1 and the second mounting frame 2 from rotating, thereby improving the stability of the device when loosening the soil.

[0028] For details, see Figure 3A pair of first support sheets 7 is provided at the other end of the top of the first mounting frame 1, and a pair of second support sheets 8 is provided at the other end of the second mounting frame 2. The first support sheets 7 are each provided with a first pin hole 701, and the second support sheets 8 are each provided with a second pin hole 801 matching the first pin hole 701. When the second mounting frame 2 is rotated upward to be parallel to the first mounting frame 1, that is, when the first mounting frame 1 and the second mounting frame 2 are folded, the second support sheet 8 is located between the pair of first support sheets 7, the first pin hole 701 is communicated with the second pin hole 801, and the first support sheet 7 abuts against the second mounting frame 2, and the second support sheet 8 is grounded to the first mounting frame 1. At this time, the first mounting frame 1 and the second mounting frame 2 can be fixed by pins or screws to prevent them from rotating.
