Description

Technical Field

[0001] The present invention relates to the technical field of garden planting, and particularly relates to a planter. Background Art

[0002] When planting in a garden, it is necessary to first dig a planting hole, and then place the plant to be planted in the planting hole.

[0003] Currently, planting holes are mainly dug with a spade. For example, the "Garden Spade for Garden Engineering" disclosed in the Chinese utility model patent with the application number CN202120959911.2 (publication number CN215011384U) includes a spade body and a spade handle on the spade body. An installation seat is arranged on the back of the spade body, and a detachable rotating head is installed in the installation seat. The rotating head and the installation seat are fixedly connected by a fastener, and a spade handle is installed on the rotating head.

[0004] However, the soil dug out with the above-mentioned garden spade is not easily taken out upward with the garden spade and easily falls back to the original position. In this way, the garden spade needs to dig the soil multiple times, and the operation is not very convenient. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a planter that is convenient for digging planting holes in view of the current situation of the prior art.

[0006] The technical solution adopted by the present invention to solve the above technical problem is: a planter, characterized in that: it includes an annular cylinder, which is vertically through for the entry and exit of soil;

[0007] The annular cylinder includes a left half cylinder and a right half cylinder that are rotatably connected at the upper part, and the corresponding rotation axis of the rotation connection extends along the radial direction of the annular cylinder;

[0008] A left extension arm extends upward from the upper left side of the left half cylinder;

[0009] A right extension arm extends upward from the upper right side of the right half cylinder and is opposite to the left extension arm;

[0010] A limiting member is located between the left extension arm and the right extension arm, and its left end is vertically movably constrained on the left extension arm, and its right end is vertically movably constrained on the right extension arm;

[0011] Under the action of an external force, there are at least two states among the limiting member, the left half cylinder and the right half cylinder:

[0012] In the first state, the limiting member is in the initial position, and the left half cylinder and the right half cylinder are in the closed state;

[0013] In the second state, the limiting member is actuated upward by an external force. Its left end acts on the left extension arm to the right, causing the left half cylinder to rotate about the rotation axis. Its right end acts on the right extension arm to the left, causing the right half cylinder to rotate about the rotation axis. The lower parts of the left half cylinder and the right half cylinder move away from each other, bringing them into a disengaged state.

[0014] The specific structures of the left and right extension arms are as follows: the left extension arm has a left mounting hole penetrating through from left to right, and a left contact surface is provided adjacent to the left mounting hole. The left contact surface extends gradually to the left from bottom to top.

[0015] The left end of the limiting member passes through the left mounting hole to the left, and has a left limiting post extending in the front-back direction and abutting against the left contact surface.

[0016] The right extension arm has a right mounting hole penetrating through from left to right, and a right contact surface is provided adjacent to the right mounting hole. The right contact surface extends gradually to the right from bottom to top.

[0017] The right end of the limiting member passes through the right mounting hole to the right, and has a right limiting post extending in the front-back direction and abutting against the right contact surface.

[0018] When the limiting member is actuated by an upward external force, its left limiting post moves upward along the left contact surface and presses the left extension arm to the right, and its right limiting post moves upward along the right contact surface and presses the right extension arm to the left.

[0019] By providing the left contact surface and the right contact surface, while the limiting member moves upward, the left end of the limiting member acts on the left contact surface, and the right end of the limiting member acts on the right contact surface, so that both the left half cylinder and the right half cylinder rotate about the rotation axis, bringing their lower parts into a disengaged state.

[0020] The structure of the limiting member can be various. Preferably, the limiting member includes a handle, the left end and the right end.

[0021] The handle is located between the left extension arm and the right extension arm.

[0022] The right side of the left end is rotatably connected to the left side of the handle.

[0023] The left side of the right end is rotatably connected to the right side of the handle.

[0024] In this way, after the user acts on the handle upward, the left end and the right end rotate and approach each other, which is beneficial to further pressing the left and right extension arms, thus facilitating the rotation of the left half cylinder and the right half cylinder to the disengaged state.

[0025] The specific structure of the rotational connection between the left half cylinder and the right half cylinder is as follows: both the upper part of the left half cylinder and the upper part of the right half cylinder have pin holes extending along the radial direction of the annular cylinder. The planter further includes a pin shaft movably arranged in the pin holes to rotatably connect the left half cylinder and the right half cylinder.

[0026] For facilitating the installation of the upper part of the left extension arm and the upper part of the right extension arm, it further includes

[0027] a cross beam, extending in the left-right direction and located between the left extension arm and the right extension arm;

[0028] The upper part of the left extension arm is movably constrained to the left end of the cross beam in the left-right direction, and the upper part of the right extension arm is movably constrained to the right end of the cross beam in the left-right direction.

[0029] In this way, the upper part of the left extension arm and the upper part of the right extension arm are installed on the cross beam; meanwhile, it is beneficial to improve the strength of the entire planter.

[0030] For facilitating the user to operate with one hand, the cross beam is located directly above the limiting member. The user holds the cross beam with the palm of the hand and holds the limiting member with four fingers, so that the user can control the opening and closing of the left half cylinder and the right half cylinder with one hand, and the operation is convenient.

[0031] To enable the left half cylinder and the right half cylinder to automatically return to the closed state, it further includes

[0032] an elastic member, arranged between the cross beam and the corresponding extension arm, so that the upper parts of the left extension arm and the right extension arm have a tendency to move away from each other in the left-right direction, thereby enabling the left half cylinder and the right half cylinder to return to the closed state.

[0033] In this way, by arranging the elastic member, it is convenient for the left half cylinder and the right half cylinder to automatically return to the closed state.

[0034] To guide the movement of the upper part of the left extension arm and the upper part of the right extension arm, the cross beam is in a cylindrical shape and has a receiving cavity penetrating through in the left-right direction; it further includes

[0035] a left guiding portion, located between the upper part of the left extension arm and the left end portion of the cross beam, and fixed to the upper part of the left extension arm, and this left guiding portion is movably arranged on the left side of the receiving cavity in the left-right direction;

[0036] a right guiding portion, located between the upper part of the right extension arm and the right end portion of the cross beam, and fixed to the upper part of the right extension arm, and this right guiding portion is movably arranged on the right side of the receiving cavity in the left-right direction;

[0037] In the first state, the elastic member is in a natural state, there is a spacing between the upper part of the left extension arm and the left end face of the cross beam, and there is a spacing between the upper part of the right extension arm and the right end face of the cross beam;

[0038] In the second state, the elastic member is in an energy storage state, the upper part of the left extension arm abuts against the left end face of the cross beam, and the upper part of the right extension arm abuts against the right end face of the cross beam.

[0039] For the convenience of spring installation, an extension rod extending left and right is arranged in the accommodating cavity of the cross beam. The left guiding part and the left extension arm are sleeved around the outer periphery of the left end of the extension rod in a left-and-right movable manner. The right guiding part and the right extension arm are sleeved around the outer periphery of the right end of the extension rod in a left-and-right movable manner;

[0040] The elastic member is a spring, which is located in the accommodating cavity of the cross beam, sleeved around the outer periphery of the extension rod and abuts against the corresponding guiding part. The spring installation is facilitated by arranging the extension rod.

[0041] In order to facilitate the alignment of the left half cylinder and the right half cylinder and the insertion of the annular cylinder into the soil, in the left half cylinder and the right half cylinder, one has a limiting groove recessed along its circumferential direction, and the other has a limiting part extending into the limiting groove;

[0042] The outer peripheral dimension of the annular cylinder gradually decreases from top to bottom;

[0043] The outer peripheral wall of the annular cylinder is provided with scales;

[0044] A recessed part is formed by locally depressing the bottom of the annular cylinder upward. There are at least two such recessed parts, and teeth are formed between adjacent two recessed parts.

[0045] The alignment of the left half cylinder and the right half cylinder is facilitated by arranging the limiting part and the limiting groove. The insertion of the annular cylinder into the soil is facilitated by designing the outer peripheral dimension and the teeth. The depth of the annular cylinder inserted into the soil is facilitated to be viewed by arranging the scales.

[0046] Compared with the prior art, the advantages of the present invention are as follows: By arranging the left half cylinder, the right half cylinder, the left extension arm, the right extension arm, and the limiting member, when the left half cylinder and the right half cylinder are in an aligned state, the user acts downward to insert the planter into the soil, and then the user lifts the planter upward. At this time, the soil remains in the annular cylinder and is taken away, and the soil is not easy to fall off, thus obtaining a planting hole; Then, the planter is taken to a position far from the planting hole, and the user lifts the limiting member upward. The limiting member is stressed and acts on the left extension arm and the right extension arm to make them rotate around the rotation axis. The lower parts of the left half cylinder and the right half cylinder move away from each other and are in a separated state, and the soil falls downward out of the annular cylinder. In this way, when the user inserts the planter into the soil once, all the soil can be taken out, and the soil will not fall back into the planting hole again. The operation is convenient, and the efficiency of digging the planting hole is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0055] Referring to Figures 1 to 7 , which is a preferred embodiment of the present invention. The planter includes main components such as an annular cylinder 1, a left extension arm 3, a right extension arm 4, a limiting member 2, a cross beam 7, an elastic member 8, a left guiding portion 5, a right guiding portion 6, an extension rod 100, etc.

[0056] Among them, the annular cylinder 1 is vertically penetrated for the entry and exit of soil. Specifically, the annular cylinder 1 includes a left half cylinder 11 and a right half cylinder 12 that are rotatably connected at the upper part, and the corresponding rotation axes of the rotational connection extend along the radial direction of the annular cylinder 1. One of the left half cylinder 11 and the right half cylinder 12 has a limiting groove 14 that is recessed along its own circumferential direction, and the other has a limiting portion 15 that extends into the limiting groove 14. Specifically, the upper parts of both the left half cylinder 11 and the right half cylinder 12 have pin holes 13 that extend along the radial direction of the annular cylinder 1, and the planter further includes a pin shaft 9 that is movably arranged in the pin holes 13 to rotatably connect the left half cylinder 11 and the right half cylinder 12. The outer peripheral dimension of the annular cylinder 1 gradually decreases from top to bottom; the outer peripheral wall of the annular cylinder 1 has graduations 16; a local position at the bottom of the annular cylinder 1 is recessed upward to form a recessed portion 17, and there are multiple such recessed portions 17, and the number can be adjusted according to needs, and teeth 18 are formed between adjacent two recessed portions 17.

[0057] The left extension arm 3 extends upward from the upper left side of the left half cylinder 11. The left extension arm 3 has a left mounting hole 31 that penetrates from left to right, and a left contact surface 32 is provided at a position adjacent to the left mounting hole 31. The left contact surface 32 gradually extends to the left from bottom to top. The left contact surface 32 is an arc surface in this embodiment, and can also be an inclined plane.

[0058] The right extension arm 4 extends upward from the upper right side of the right half cylinder 12 and is opposite to the left extension arm 3. The right extension arm 4 has a right mounting hole 41 penetrating from left to right, and a right contact surface 42 is provided at a position adjacent to the right mounting hole 41. The right contact surface 42 gradually extends to the right from bottom to top. The right contact surface 42 is an arc surface in this embodiment, and it can also be an inclined plane.

[0059] The limiting member 2 includes a handle 21, a left end portion 22, and a right end portion 23. The handle 21 is located between the left extension arm 3 and the right extension arm 4; the left end portion 22 is rotatably connected to the left side of the handle 21. The left end portion 22 passes through the left mounting hole 31 to the left, and has a left limiting column 221 extending in the front-rear direction and abutting against the left contact surface 32; the right end portion 23 is rotatably connected to the right side of the handle 21. The right end portion 23 passes through the right mounting hole 41 to the right, and has a right limiting column 231 extending in the front-rear direction and abutting against the right contact surface 42. The limiting member 2 is located between the left extension arm 3 and the right extension arm 4. Its left end portion 22 is vertically movably constrained at the left mounting hole 31, and its right end portion 23 is vertically movably constrained at the right mounting hole 41; under the action of an external force, there are two states among the limiting member 2, the left half cylinder 11 and the right half cylinder 12: in the first state, the limiting member 2 is in the initial position, and the left half cylinder 11 and the right half cylinder 12 are in the butted state; in the second state, the limiting member 2 is acted on by an external force and moves upward. Its left end portion 22 acts on the left extension arm 3 to the right to make the left half cylinder 11 rotate around the rotation axis, and its right end portion 23 acts on the right extension arm 4 to the left to make the right half cylinder 12 rotate around the rotation axis. The lower parts of the left half cylinder 11 and the right half cylinder 12 move away from each other to make the two in the separated state. Specifically, when the limiting member 2 is acted on by an upward external force, its left limiting column 221 moves upward along the left contact surface 32 and squeezes the left extension arm 3 to the right, and its right limiting column 231 moves upward along the right contact surface 42 and squeezes the right extension arm 4 to the left.

[0060] The cross beam 7 extends in the left-right direction and is located between the left extension arm 3 and the right extension arm 4; the cross beam 7 is in a cylindrical shape and has a receiving cavity 71 penetrating from left to right. The cross beam 7 is located directly above the limiting member 2. The upper part of the left extension arm 3 is vertically movably constrained at the left end of the cross beam 7, and the upper part of the right extension arm 4 is vertically movably constrained at the right end of the cross beam 7.

[0061] The elastic member 8 is disposed between the cross beam 7 and the corresponding extension arm, so that the upper portions of the left extension arm 3 and the right extension arm 4 have a tendency to move away from each other in the left-right direction, thereby causing the left half cylinder 11 and the right half cylinder 12 to return to the mating state. The elastic member 8 is a spring, and the spring is located in the accommodation cavity 71 of the cross beam 7, and is sleeved on the outer periphery of the extension rod 100 and abuts against the corresponding guiding portion. Specifically, in this embodiment, there are two left and right springs, and a limiting portion is provided in the middle of the accommodation cavity 71 of the cross beam 1. The two ends of the left spring respectively abut against the left guiding portion 5 and the limiting portion, and the two ends of the right spring respectively abut against the right guiding portion 6 and the limiting portion. The elastic member 8 can also be an elastic strip.

[0062] The left guiding portion 5 is located between the upper portion of the left extension arm 3 and the left end portion of the cross beam 7, and is fixed to the upper portion of the left extension arm 3. The left guiding portion 5 is movably disposed in the left side of the accommodation cavity 71 in the left-right direction.

[0063] The right guiding portion 6 is located between the upper portion of the right extension arm 4 and the right end portion of the cross beam 7, and is fixed to the upper portion of the right extension arm 4. The right guiding portion 6 is movably disposed in the right side of the accommodation cavity 71 in the left-right direction.

[0064] See Figures 1 to 3 , in the first state, the elastic member 8 is in the natural state, there is a gap between the upper portion of the left extension arm 3 and the left end face of the cross beam 7, and there is a gap between the upper portion of the right extension arm 4 and the right end face of the cross beam 7.

[0065] See Figures 5 to 7 , in the second state, the elastic member 8 is in the energy storage state, the upper portion of the left extension arm 3 abuts against the left end face of the cross beam 7, and the upper portion of the right extension arm 4 abuts against the right end face of the cross beam 7.

[0066] The extension rod 100 is disposed in the accommodation cavity 71 of the cross beam 7 and extends left and right. The left guiding portion 5 and the left extension arm 3 are sleeved on the outer periphery of the left end portion of the extension rod 100 in a left-right movable manner, and the right guiding portion 6 and the right extension arm 4 are sleeved on the outer periphery of the right end portion of the extension rod 100 in a left-right movable manner.

[0067] The working principle and usage method of the embodiment of the present invention are as follows.

[0068] Figures 1 to 3 For the initial state of the planter, the user holds the cross beam 7 and applies a downward force, and the annular cylinder 1 is inserted downward into the soil. The insertion depth of the annular cylinder 1 can be read from the scale 16;

[0069] Then the user lifts the planter upward. At this time, the soil remains in the annular cylinder 1 and is dug away, thereby obtaining a planting hole;

[0070] Then, move the planter to a position away from the planting hole. The user lifts the limiting member 2 upward. After the limiting member 2 is stressed, the left limiting column 221 moves upward along the left contact surface 32 and simultaneously squeezes the left extension arm 3 to the right. The right limiting column 231 moves upward along the right contact surface 42 and simultaneously squeezes the right extension arm 4 to the left. According to the lever principle, the left extension arm 3 drives the left half cylinder 11 to rotate, and the right extension arm 4 drives the right half cylinder 12 to rotate. In this way, the lower parts of the left half cylinder 11 and the right half cylinder 12 move away from each other (see Figures 5 to 7 ), and the soil drops downward. The user can operate it with one hand. Specifically, hold the cross beam 7 with the palm and hold the limiting member 2 with the four fingers, which is convenient to operate.

[0071] After the user releases the limiting member 2, the limiting member 2 returns downward to the initial position, and the left half cylinder 11 and the right half cylinder 12 return to the closed state.

[0072] When digging the next planting hole, repeat the above steps.

[0073] This planter can also be used for transplanting. For example, the plant to be transplanted is dug up by the planter along with the soil. Then, at a suitable position, after the user releases the limiting member 2, the soil and the plant fall down together. In this way, the plant is moved to a suitable position along with the soil through the planter.
