Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree planting, in particular to a fixed-point pit digging device for fruit trees. Background Art

[0002] Fruit trees are woody plants used to produce fruit. There are many types of fruit trees, including apples, pears, peaches, etc. The growth process of fruit trees usually includes stages such as sowing or grafting propagation, planting, growth, flowering and fruiting, fruit ripening and harvesting. Fruit trees need sufficient sunlight, suitable temperature, appropriate amount of water and fertile soil to grow, and produce seeds (fruits) through the process of pollination and fertilization. Fruit trees not only provide humans with abundant fruits, but are also an important part of the agricultural economy, and have an important impact on human diet and economic life.

[0003] When planting smaller fruit tree seedlings, you need to dig several holes in the ground first, place the roots of the fruit tree seedlings in the holes, and finally fill the holes and compact them to complete the initial planting of the fruit trees. However, when digging holes, you need to choose the spacing between holes according to different fruit trees, that is, according to the tree species and tree growth habits (canopy size, competition between trees, etc.), soil and water resources (soil fertility, drainage conditions, water supply, etc.), and planting design requirements (aesthetics and fruit tree maintenance).

[0004] However, in the existing fruit tree planting, the spacing between the holes is mostly determined by visual observation, step measurement or tape measure. However, the determined spacing between the holes often has deviations, and the positions of adjacent holes need to be confirmed each time a hole is dug. Therefore, accurately determining the position of the holes through a positioning mechanism and arranging the multiple holes in a rectangular array is a design consideration for the present application.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] See also Figure 1-4 This embodiment provides a device for digging holes at fixed points in fruit trees, comprising a positioning rod 1. There are two positioning rods 1, and the two positioning rods 1 are used to locate two adjacent holes respectively.

[0025] like Figure 1 As shown, the outer wall of the positioning rod 1 is fixedly sleeved with a mounting plate 4, and the mounting plate 4 is slidably inserted with a plurality of sliding racks 41, and the plurality of sliding racks 41 are evenly distributed in a circular array with the central axis of the positioning rod 1 as the center. The lower end of the sliding rack 41 is fixedly connected with a scraper 42, and the sliding rack 41 is moved downward, and the plurality of scrapers 42 can be combined into a multi-faceted pyramid structure. For example, three sliding racks 41 are provided, such as Figure 2 As shown, three blades 42 can be combined into a triangular pyramid structure.

[0026] When in use, the lower end of the positioning rod 1 is erected on the ground, the positioning rod 1 is fixed by hand, and the sliding frame 41 is stepped on obliquely downward with the foot to insert the shovel blades 42 into the ground. After all the shovel blades 42 are inserted, the positioning rod 1 is pulled upward to pull out the shovel blades 42. The shoveled soil is retained in the polygonal cone formed by the shovel blades 42, and a polygonal cone-shaped pit is formed on the ground.

[0027] The lower end of the positioning rod 1 is relatively sharp. After the positioning rod 1 is erected on the ground, the lower end of the positioning rod 1 will be inserted into the ground. In order to prevent the lower end of the positioning rod 1 from being inserted into the ground, a contact plate 11 is fixedly connected to the lower end of the positioning rod 1. Figure 1 As shown, the contact plate 11 increases the contact area between the lower end of the positioning rod 1 and the ground, thereby preventing the positioning rod 1 from being inserted into the ground.

[0028] When planting the same fruit trees, it is necessary to ensure that the spacing between adjacent holes is the same when digging holes to meet the fruit tree production needs and aesthetics. Therefore, in order to ensure that the spacing between adjacent holes is the same, a positioning mechanism 2 is provided between the two positioning rods 1.

[0029] like Figure 1 and Figure 3 As shown, the positioning mechanism 2 includes a cylindrical rod 21, a sliding rod 22 and a sleeve 23. Among them, one end of the cylindrical rod 21 is provided with a plug hole, one end of the sliding rod 22 is slidably inserted in the plug hole, and two sleeves 23 are provided, one sleeve 23 is fixedly connected to the end of the cylindrical rod 21 away from the plug hole, and the other sleeve 23 is fixedly connected to the end of the sliding rod 22 away from the cylindrical rod 21. The upper end of the positioning rod 1 is fixedly connected to the plug rod, and the sleeve 23 is sleeved on the plug rod.

[0030] When in use, the distance between the two positioning rods 1 can be adjusted by pulling the sliding rod 22 from the insertion hole of the barrel rod 21 , and the outer wall of the sliding rod 22 and the inner wall of the insertion hole of the barrel rod 21 form an interaction force, thereby forming a damping force to fix the sliding rod 22 .

[0031] Fixing the sliding rod 22 only by damping force has poor stability. When the sliding rod 22 or the cylindrical rod 21 is subjected to external force, the sliding rod 22 will shrink into the cylindrical rod 21, and the extended length of the sliding rod 22 cannot be guaranteed. Therefore, in order to further fix the extended sliding rod 22, a knob 211 is threadedly connected at the edge of the upper end of the cylindrical rod 21 near the jack hole. Figure 3 As shown, by rotating the knob 211, the lower end of the knob 211 contacts the upper end surface of the sliding rod 22, and by tightening the knob 211, the knob 211 squeezes the sliding rod 22, and then the sliding rod 22 can be further fixed by increasing the damping force between the sliding rod 22 and the knob 211, and between the sliding rod 22 and the bottom of the insertion hole of the barrel rod 21.

[0032] However, different fruit trees have different spacing limits. In order to determine the spacing between two adjacent holes, a length scale is engraved on the upper end of the sliding rod 22. By pulling out the sliding rod 22 and aligning the end of the tube rod 21 with the plug hole with the scale, the scale can be read to determine the spacing between the two positioning rods 1.

[0033] When planting multiple fruit trees of the same variety, the dug holes need to be arranged in a rectangular array to ensure that the spacing between the holes and all surrounding holes is the same. Therefore, it is necessary to determine the horizontal angles of the barrel rod 21 and the sliding rod 22 on the positioning rod 1. In order to fix the positions of the barrel rod 21 and the sliding rod 22 on the positioning rod 1, a positioning mechanism 2 is provided above the outer wall of the positioning rod 1.

[0034] There are four fixing mechanisms 3, and the four fixing mechanisms 3 are evenly distributed in a circular array with the central axis of the positioning rod 1 as the center. Figure 4As shown, the fixing mechanism 3 includes a card block 31, an elastic member 32 and a shift block 33. A sliding groove is provided at the upper end of the positioning rod 1, and a sliding cavity is provided on the outer side wall of the positioning rod 1, and the sliding groove and the sliding cavity are connected to each other. There are two notches at the upper end of the sliding groove. The card block 31 is slidably installed in the sliding groove, and the elastic member 32 is fixedly installed in the sliding groove, that is, the lower end of the elastic member 32 is fixedly connected to the bottom of the sliding groove, and the upper end of the elastic member 32 is fixedly connected to the lower end of the card block 31. The elastic member 32 is set as a spring, and an upward elastic force is applied to the card block 31 through the elastic member 32, so that the upper two ends of the card block 31 extend from the two notches of the sliding groove respectively.

[0035] like Figure 4 As shown, both ends of the block 31 extending from the slot of the slide groove are provided with inclined surfaces, and the outer wall of the sleeve 23 is fixedly connected with a fixed block 231. When the barrel rod 21 or the sliding rod 22 rotates, the sleeve 23 rotates at the upper end of the positioning rod 1, thereby driving the fixed block 231 to rotate synchronously. During the rotation of the fixed block 231, the lower edge of the fixed block 231 contacts the inclined surface of the block 31, exerting an inclined downward pressure on the block 31, thereby driving the block 31 to shrink into the slide groove, and at this time, the elastic member 32 shrinks. When the fixed block 231 rotates to the groove at the upper end of the block 31, the upper end of the block 31 extends from the slot of the slide groove due to the elasticity of the elastic member 32, so that the fixed block 231 is engaged in the groove of the block 31. Then the fixed block 231 is limited to fix the angle of the sleeve 23.

[0036] like Figure 4 As shown, the shift block 33 is slidably installed in the sliding cavity, and the shift block 33 is fixedly connected to the end surface of the clamping block 31. By shifting the shift block 33 downward, the clamping block 31 can be driven to move downward and shrink into the slide groove of the positioning rod 1. At this time, the sleeve 23 can be rotated again. Since the four clamping blocks 31 are arranged in a cross shape, after the sleeve 23 is rotated, when the adjacent clamping blocks 31 fix the sleeve 23 again, the cylinder rod 21 and the sliding rod 22 rotate 90 degrees.

[0037] When in use, first determine the positions of two adjacent pits through the two positioning rods 1, then respectively sleeve the two sleeves 231 of the positioning mechanism 2 on the upper ends of the two positioning rods 1, tighten the knob 211 to fix the sliding rod 22, rotate the positioning rod 1 so that the fixing block 231 is engaged in the groove of the clamping block 31, and fix the position of the shovel blade 42. Move the shovel blade 42 downward by stepping on it to dig out the pit, and the shovel blade 42 installed on the two positioning rods 1 can dig two adjacent pits. At this time, pull the positioning rod 1 upward to bring out the soil in the polygonal cone formed by the shovel blade 42, and pull the sliding frame 41 upward to move the shovel blade 42 to discharge the shoveled soil.

[0038] After determining and digging two adjacent pits, move the blade 42 of a positioning rod 1 downward, insert the blade 42 forming the polygonal pyramid back into the original pit, so that this positioning rod 1 forms a fixed positioning rod 1. At this time, the other positioning rod 1 is located directly above the other pit. Move the block 33 of the fixed positioning rod 1 to drive the sleeve 23 above the fixed positioning rod 1 to rotate. After the fixed block 231 is engaged in the groove of the adjacent block 31, the other positioning rod 1 rotates 90 degrees with the fixed positioning rod 1 as the center. At this time, move the blade 42 downward to dig a third pit around the fixed positioning rod 1. Similarly, four pits can be dug around the fixed positioning rod 1. The spacing between the four pits and the pit below the fixed positioning rod 1 is the same. Repeat the above operation many times to dig a rectangular array of pits.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
