Description

TECHNICAL FIELD

[0001] The utility model relates to fruit planting equipment technical field, concretely is a soil loosening device for fruit planting. BACKGROUND

[0002] Compared with the traditional mechanical soil loosening tool, the gas soil loosening is less damaged to the root system of the fruit tree. Because the gas penetrates into the soil through the pore, while loosening the soil, it will not cut or extrude the root system directly like the mechanical tool. For example, in the orchard of rare varieties of fruit trees or the planting area of the root system fragile fruit trees (such as blueberry), the gas soil loosening is a relatively ideal choice.

[0003] The layout mode of the injection point will directly affect the effective range of the pneumatic soil loosening. The common layouts are triangular layout and square layout. Before the gas soil loosening work is carried out, the staff will predict the distance between the injection points according to the type of the soil and other factors, so as to achieve the purpose of arranging the distribution of the injection points in advance. This way of arranging the injection points in advance lacks practical basis, and if the distance between the injection points obtained by prediction is too large or too small, the staff needs to adjust the positions of all the injection points arranged in advance. This way of arranging the distribution lacks work efficiency.

[0004] Therefore, there is an urgent need for a soil loosening device for fruit planting to solve the above problems. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0021] Please refer to Figs. 1 to 4 The utility model provides an embodiment: a soil loosening device for fruit planting, including air injector 1, air injector 1 is installed with air injection needle 2, the periphery of air injection needle 2 is installed with support foot 3, and layout mechanism 4 is installed on support foot 3;

[0022] Air injector 1 provides high pressure gas for the soil loosening device, and the high pressure gas provided by air injector 1 is sprayed from the air injection needle 2 installed on air injector 1. Air injection needle 2 is inserted into the soil to work. When the high pressure gas is injected into the soil pore, the force between the soil particles will change. Thus, the purpose of loosening the soil is achieved.

[0023] Layout mechanism 4 includes first connecting shaft 41, second connecting shaft 42, two telescopic rods 43, two connecting rods 44, two fixed feet 45 and two fixed screws 46, first connecting shaft 41 is installed on support foot 3, second connecting shaft 42 is installed in the inside of first connecting shaft 41, two telescopic rods 43 are respectively installed on first connecting shaft 41 and second connecting shaft 42, connecting rod 44 is installed on one end of telescopic rod 43 away from support foot 3, fixed foot 45 is installed on one end of connecting rod 44 away from support foot 3, and fixed screw 46 is installed on one end of telescopic rod 43 away from support foot 3.

[0024] First connecting shaft 41 and second connecting shaft 42 are connected with a telescopic rod 43 respectively. The function of first connecting shaft 41 and second connecting shaft 42 is to drive telescopic rod 43 to rotate around support foot 3, so as to adjust the included angle between the two telescopic rods 43. Changing the included angle between the telescopic rods 43 can help the staff to layout the air injection points.

[0025] Connecting rod 44 is slidingly connected in the inside of telescopic rod 43, so as to adjust the common length of connecting rod 44 and telescopic rod 43. The staff can adjust the common length of connecting rod 44 and telescopic rod 43 according to the estimated air injection point spacing. When it is found that the estimated air injection point spacing is too large or too small during the layout process, the staff can adjust the connecting rod 44, and re-adjust the distance between the connecting rod 44 and the telescopic rod 43 to a suitable distance.

[0026] When the worker finishes adjusting the telescopic rod 43 and the connecting rod 44, the fixed screw 46 is adjusted. Each fixed screw 46 is inserted into the inside of one end of the telescopic rod 43 away from the support foot 3, and each fixed screw 46 penetrates the surface of one end of the inside of the telescopic rod 43 and is in contact with the surface of the connecting rod 44. When the fixed screw 46 penetrates the inner wall of the telescopic rod 43, one end of the fixed screw 46 is in contact with the surface of the connecting rod 44. As the fixed screw 46 continues to screw in, the pressure of the contact surface between the fixed screw 46 and the connecting rod 44 also gradually increases, thereby locking the position of the connecting rod 44 inside the telescopic rod 43, so that the telescopic rod 43 and the connecting rod 44 stably maintain the current positional relationship, preventing the connecting rod 44 from moving freely with the telescopic rod 43 and affecting the actual application effect.

[0027] The fixed foot 45 plays the role of an anchor point for the soil loosening device. When the worker uses the soil loosening device to punch an injection point on the ground, the worker can place the fixed foot 45 into the punched injection point, take the fixed foot 45 as the center, and take the telescopic rod 43 and the connecting rod 44 as the rotating radius to layout the next injection point. The length of the telescopic rod 43 and the connecting rod 44 is the worker's estimated injection point interval. If there are two or more injection points on the construction site, the worker can insert two fixed feet 45 into the corresponding injection points, adjust the length of the telescopic rod 43 and the connecting rod 44 to the preset injection point interval, and determine the position of the third injection point through the positions of the two injection points and the distance between the injection points, so as to achieve the purpose of loosening the soil while laying out the injection points.

[0028] Specifically, the layout mechanism 4 is installed with an angle fixing mechanism 5, and the angle fixing mechanism 5 includes positioning holes 51 and positioning needles 52. The positioning holes 51 are uniformly distributed on the first connecting shaft 41 and the second connecting shaft 42, and the positioning needles 52 are installed in the inside of the first connecting rod 44 and the second connecting shaft 42 through the positioning holes 51.

[0029] The positioning holes 51 are uniformly distributed on the first connecting shaft 41 and the second connecting shaft 42, and the angles between them can be special angles, such as 15 degrees, 30 degrees, etc. In this way, the worker can determine the included angle between the first connecting shaft 41 and the second connecting shaft 42 according to how many positioning holes 51 are spaced between them.

[0030] When the worker wants to set a special angle between the first connecting shaft 41 and the second connecting shaft 42 to help himself arrange the injection points, such as the angle between the first connecting shaft 41 and the second connecting shaft 42 is 60 degrees, the worker uses the positioning needle 52 to fix the first connecting shaft 41 and the second connecting shaft 42. With the first injection point as the origin, the worker adjusts the telescopic rod 43 and the connecting rod 44 installed on the first connecting shaft 41 to the estimated injection point interval, and obtains the second injection point with the injection point interval as the radius. At this time, the worker adjusts the telescopic rod 43 and the connecting rod 44 on the second connecting shaft 42 to the estimated injection point interval, because the triangle formed by the two fixing feet 45 and the injection needle 2 has two equal sides and the angle between the two equal sides is 60 degrees. At this time, the triangle formed by the two fixing feet 45 and the injection needle 2 is an equilateral triangle, and at this time the dead angle area without loosening the soil is smaller, and the effective range can more fully cover the entire test area.

[0031] The worker can also fix the angle between the first connecting shaft 41 and the second connecting shaft 42 to 90 degrees according to the specific situation of the loosening site, and arrange the injection points in a square layout.

[0032] Specifically, the injection machine 1 is provided with a handle 6. The handle 6 can help the worker stabilize the injection direction of the injection machine 1, prevent the injection needle 2 from tilting, and affect the loosening effect.

[0033] Specifically, the positioning hole 51 penetrates the first connecting shaft 41 and the second connecting shaft 42, ensuring that the positioning needle 52 can connect and fix the first connecting shaft 41 and the second connecting shaft 42.

[0034] Specifically, the positioning holes 51 on the first connecting shaft 41 and the second connecting shaft 42 correspond to each other, preventing the problem that the positioning needle 52 cannot enter the second positioning hole 51 after penetrating the first connecting shaft 41 because the positioning holes 51 do not correspond to each other.

[0035] Working principle:

[0036] Suppose the worker uses a triangular injection layout to loosen the soil.

[0037] Before using the loosening device, the worker first estimates the injection hole interval according to the soil type of the loosening construction site and the type of the fruit trees planted.

[0038] The worker first selects an injection point at the edge of the loosening construction site and inserts the injection needle 2 into the deep soil at this injection point. After inserting the injection needle 2, the worker turns on the injection machine 1 and holds the handle 6 tightly, and blows the high-pressure gas generated by the injection machine 1 into the soil through the injection needle 2, thereby completing the loosening.

[0039] When the worker finishes the loosening task of the first injection point, the injection layout is started.

[0040] The worker pulls out the connecting rod 44 from the inside of the telescopic rod 43 until the length of the telescopic rod 43 and the connecting rod 44 is the same as the estimated injection hole spacing of the worker, and the worker tightens the fixing screw 46 to fix the connecting rod 44 in the inside of the telescopic rod 43 and cannot slide.

[0041] After the worker adjusts the length of the telescopic rod 43 and the connecting rod 44, the fixing foot 45 on the connecting rod 44 is placed into the injection hole left by the loosening work of the injection needle 2, and the fixing foot 45 is used as a dot, and the next injection point is laid out with the telescopic rod 43 and the connecting rod 44 as the rotating radius. When the worker finds the next injection point, the loosening work is carried out using the injection machine 1.

[0042] After the worker finishes the loosening work of the second injection hole, the soil loosening effect between the two injection holes is observed. When the worker finds that the estimated injection point spacing is too large or too small, the worker adjusts the distance between the connecting rod 44 and the telescopic rod 43 to obtain a suitable injection hole spacing.

[0043] When the worker obtains a suitable injection hole spacing, the worker starts to adjust the angle of the first connecting shaft 41 and the second connecting shaft 42. After the worker adjusts the included angle of the first connecting shaft 41 and the second connecting shaft 42 to a suitable angle, the positioning needle 52 is inserted into the positioning hole 51 to lock the angle of the first connecting shaft 41 and the second connecting shaft 42.

[0044] After adjusting the angle, the worker adjusts the connecting rod 44 on the other telescopic rod 43 to obtain a suitable injection hole spacing obtained by the worker.

[0045] After adjusting the loosening device, the worker can carry out the loosening work while laying out the injection hole, which improves the work efficiency.

[0046] It is apparent for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but rather can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Accordingly, the embodiments should be considered as exemplary only, and are not limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
