Description

Technical Field

[0001] The invention relates to the technical field of fruit tree planting, in particular to a soil loosening device for fruit tree planting. Background Art

[0002] Soil loosening devices in fruit tree planting are designed to improve soil structure, promote root respiration and water penetration, and increase the growth and yield of fruit trees;

[0003] However, the existing soil loosening devices in fruit tree planting have the following problems in the process of loosening dry hard soil:

[0004] Problem 1: Existing loosening blades have insufficient penetration, which can easily cause high friction and excessive wear during the loosening process, and may even damage the blade. At the same time, due to insufficient penetration, existing loosening blades cannot evenly loosen the soil, which may cause the depth of the soil layer to be uneven, affecting the uniformity and effectiveness of agricultural operations.

[0005] On the basis of question one, question two is proposed: after the dry hard soil is loosened and crushed evenly, the soil will gradually form sandy soil. The sandy soil has a loose structure, good air permeability, large particle size, and rapid water loss. After the hard soil forms sandy soil, even if the soil can be easily loosened by a loosening shovel, it is easy to cause the surface sand to be lost after the soil surface is loosened, causing soil degradation. At the same time, dust is easily generated in the process of loosening the sandy soil, affecting the surrounding environment. Therefore, the loosening device needs to be additionally designed with a structure to control sand loss. In response to the above problems, the inventor proposes a soil loosening device for fruit tree planting to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Embodiment 1

[0053] like Figure 1 - Fig.13 As shown, the present invention provides a soil loosening device for fruit tree planting, comprising a frame 1, a sliding frame 2, a second crushing assembly 8 and a water pump assembly 10, the top of the frame 1 is slidably connected to the sliding frame 2, and a lifting drive assembly 3 is arranged between the frame 1 and the sliding frame 2;

[0054] A second motor 4 is installed on the top of the sliding frame 2, and a crank wheel assembly 9 is arranged on the inner side of the sliding frame 2;

[0055] During the operation of the crank wheel assembly 9, the second crushing assembly 8 and the water pump assembly 10 are operated in sequence;

[0056] A first crushing assembly 5 is disposed at one end of the sliding frame 2, a second crushing assembly 8 is disposed in the middle of the frame 1 and the sliding frame 2, and a water pump assembly 10 is disposed at the rear ends of the sliding frame 2 and the frame 1;

[0057] The first crushing assembly 5 crushes the soil first, the second crushing assembly 8 further crushes the crushed soil and turns it upside down at the same time, and the water pump assembly 10 moistens and reduces dust on the turned soil;

[0058] A U-shaped frame 15 is installed on the inner wall of the sliding frame 2, and the U-shaped frame 15 supports the crank wheel assembly 9. A water tank 6 is installed on the upper surface of the U-shaped frame 15, and the water tank 6 is connected to the water pump assembly 10. The U-shaped frame 15 is used to support the water tank 6 and the water pump assembly 10;

[0059] The outer surface of the second crushing component 8 is coated with a Teflon coating, and the output end of the water pump component 10 extends to the second crushing component 8. When the second crushing component 8 turns the soil, the soil deep is moistened, and the Teflon coating prevents the soil from sticking to the second crushing component 8;

[0060] By adopting the above technical solution, the lifting drive assembly 3 between the frame 1 and the sliding frame 2 can control the lifting movement of the sliding frame 2 relative to the frame 1. This structure provides a different height and position adjustment basis for the subsequent work of each component. The second motor 4 installed on the top of the sliding frame 2 provides power for part of the operation of the entire device. The first crushing assembly 5 first crushes the soil, which is the first step of the entire soil processing process, and preliminarily crushes large pieces of soil into smaller pieces;

[0061] The crank wheel assembly 9 plays a key role in controlling the sequence during operation. It enables the second crushing assembly 8 and the water pump assembly 10 to operate in sequence. After the first crushing assembly 5 works, the second crushing assembly 8 further crushes the crushed soil that has been preliminarily crushed, and turns it up and down at the same time. During the turning process, since the output end of the water pump assembly 10 extends to the second crushing assembly 8, it can moisten the deep soil. In addition, the Teflon coating on the outer surface of the second crushing assembly 8 prevents soil from sticking to it, ensuring its normal turning and crushing functions. When the second crushing assembly 8 turns the soil, the turned soil is moistened and dust-reduced. The water tank 6 is installed on the upper surface of the U-shaped frame 15 and is connected to the water pump assembly 10 to provide a water source for the water pump assembly 10.

[0062] Embodiment 2

[0063] A sleeve 101 is fixedly connected to the frame 1, a buffer spring 102 is installed inside the sleeve 101, a connecting rod 201 is fixedly connected to the lower surface of the sliding frame 2, and the connecting rod 201 is slidably connected to the inner wall of the sleeve 101;

[0064] The lifting drive assembly 3 includes a fixed frame 301, which is fixedly connected to the outer wall of the sliding frame 2. A first motor 302 is installed on the upper surface of the fixed frame 301. A worm 303 is installed on the output shaft of the first motor 302. The worm 303 is rotatably connected to the fixed frame 301. A rotating shaft is rotatably connected between the two ends of the fixed frame 301. A worm wheel 304 is fixedly connected to the outer wall of the rotating shaft. The worm 303 drives the worm wheel 304. The worm 303 and the worm wheel 304 form a self-locking relationship. A rack 305 is fixedly connected to the outer wall of the sliding frame 2. The worm wheel 304 and the rack 305 are meshed with each other.

[0065] By adopting the above technical solution, when the height of the sliding frame 2 needs to be adjusted, the buffer spring 102 plays a buffering role. When the first motor 302 is started, the worm 303 starts to rotate. Due to the transmission relationship between the worm 303 and the worm wheel 304, the rotation of the worm 303 drives the worm wheel 304 to rotate. Here, the self-locking between the worm 303 and the worm wheel 304 is an important feature. When the worm 303 stops rotating, the worm wheel 304 can maintain the current position without rotating automatically due to external forces (such as gravity, etc.), which ensures the stability of the sliding frame 2 after it is lifted to a certain position.

[0066] Embodiment 3

[0067] The crank wheel assembly 9 includes two round handles 901, two crank rods 902 and two connecting blocks 903. The round handles 901 are rotatably connected to the inner wall of the sliding frame 2 through connecting shafts, and one of the round handles 901 is connected to the output shaft of the second motor 4 through the connecting shaft.

[0068] The connecting shafts of the two round handles 901 are connected by a transmission belt, the two curved rods 902 are respectively rotatably connected to the outer wall of the round handle 901, and the two connecting blocks 903 are respectively rotatably connected to the bottom of the curved rod 902;

[0069] By adopting the above technical solution, when the second motor 4 is started, the round handle 901 connected thereto starts to rotate, and the connecting shafts of the two round handles 901 are connected by a transmission belt. In this way, when one round handle 901 rotates under the drive of the second motor 4, the other round handle 901 will also rotate synchronously through the transmission effect of the transmission belt. This transmission method can ensure that the two round handles 901 rotate at the same speed and direction. As the round handle 901 rotates, the crank 902 will rotate with its connection point with the round handle 901 as the axis, as shown in FIG. Fig.10 As shown, in the initial state, one of the curved rods 902 is rotatably connected to the top end of the round handle 901, and the other curved rod 902 is rotatably connected to the bottom end of the round handle 901. During operation, the second crushing component 8 and the water pumping component 10 are controlled to run in sequence.

[0070] Embodiment 4

[0071] The second crushing assembly 8 includes a first connecting pipe 801, which is fixedly connected to the outer wall of the connecting block 903, a guide rail 802 is installed on the lower surface of the first connecting pipe 801, and a cone 803 is connected to the first connecting pipe 801. The cone 803 is set as a hollow structure, and a drainage hole 804 is set at the bottom of the cone 803.

[0072] By adopting the above technical solution, when the connecting block 903 in the crank wheel assembly 9 moves, the first connecting pipe 801 will move accordingly, and the cone thorns of the cone 803 can puncture and crush the soil. At the same time, the arc-shaped inclined plate 805 will also squeeze and flip the soil during the movement, further crushing the soil. When penetrating into the soil, the soil pushes the arc-shaped inclined plate 805 and enters from the bottom to the inner side of the arc-shaped inclined plate 805. The cone 803 and the arc-shaped inclined plate 805 approach each other to squeeze the soil. When the second crushing assembly 8 moves upward, under the action of gravity, the arc-shaped inclined plate 805 opens and the soil is discharged. When the soil needs to be moistened, water can flow out from the drainage hole 804 through the hollow structure of the cone 803. Due to the rotation or movement of the arc-shaped inclined plate 805, they can change the direction and range of water outflow, so that the water can be more evenly distributed in the soil, thereby achieving the purpose of moistening the soil, and at the same time, it can also play a role in dust reduction to a certain extent.

The extended end of the piston rod 1002 is connected to the connecting block 903. The top of the piston rod 1002 is connected to a one-way valve 1003. One end of the one-way valve 1003 is connected to the water tank 6. The bottom outer wall of the piston rod 1002 is connected to a watering plate 1004.

[0075] By adopting the above-mentioned technical solution, when the crank wheel assembly 9 moves, the movement of the connecting block 903 drives the piston rod 1002 to move. The function of the one-way valve 1003 is to ensure that water can only flow from the water tank 6 to the direction of the piston rod 1002 to prevent water backflow. When the piston rod 1002 moves downward, the inhaled water will be squeezed and then sprayed out through the sprinkler plate 1004 connected to the outer wall at the bottom of the piston rod 1002.

[0076] Furthermore, the outer wall of the first connecting tube 801 is connected with a second connecting tube 11, and the second connecting tube 11 is configured as a retractable structure;

The two ends of the transmission rod 1202 are rotatably connected to the rotating disk 1201 and the movable frame 1203 respectively.

[0083] By adopting the above-mentioned technical solution, during the rotation of the rotating disk 1201, the movable frame 1203 is pushed back and forth by the transmission rod 1202. During the back and forth movement, the steel ball 14 collides and cooperates with the elastic strip 1502, and the spring 13 gives the steel ball 14 elasticity.
