[0037] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0038] like Figures 1 to 7As shown, an embodiment of the present invention provides a pear seedling breeding device that is easy to transplant, including a box body 1, a placement slot plate 2 horizontally arranged in the box body 1, the top and front side of the box body 1 have openings, the top has a box cover, the bottom has supporting feet, and the inner walls on both sides of the box body 1 are provided with mounting grooves that match the placement slot plate 2, and the placement slot plate 2 is clamped in the mounting groove of the box body 1; an electric telescopic rod 3 is arranged on the inner bottom wall of the box body 1, and a push plate 4 is horizontally arranged on the telescopic end of the electric telescopic rod 3 and located below the placement slot plate 2, the push plate 4 is parallel to the placement slot plate 2, and the push plate 4 can be pushed up and down in the box body 1 by the electric telescopic rod 3; a plurality of vertical push plates 4 are evenly spaced and arranged on the top of the push plate 4 Rod 5, in this embodiment, all vertical rods 5 are arranged in a row, in other embodiments of the present invention, all vertical rods 5 are arranged and can be arranged in two or three rows, etc.; a chassis 6 is arranged at the top of the vertical rod 5, a rotating block 7 is arranged at the bottom of the chassis 6 and located on the outside of the vertical rod 5, a mounting through hole is opened at the center of the rotating block 7 for the vertical rod 5 to pass through, and a retracting and unfolding mechanism 8 is respectively arranged on the four side walls of the rotating block 7 and is used to enclose the chassis 6; wherein, a through hole corresponding to the chassis 6 is opened on the placement slot plate 2, and when the top outer wall of the retracting and unfolding mechanism 8 contacts the inner wall of the through hole on the placement slot plate 2, the retracting and unfolding mechanism 8 is retracted and contacts the outer edge of the corresponding chassis 6, and the side edges of the adjacent retracting and unfolding mechanisms 8 are in contact. When the retracting and unfolding mechanism 8 on the same rotating block 7 is retracted, it can enclose a seedling raising cavity for seedling raising between it and the chassis 6, which is convenient for breeding pear seedlings; and the aperture of the through hole on the placement slot plate 2 matches the outer diameter of the corresponding four retracting and unfolding mechanisms 8 after enclosing.

[0039] like Figures 3 to 5As shown, the retracting and unfolding mechanism 8 includes a track plate 81 arranged on the side wall of the rotating block 7, a sliding groove is provided on the track plate 81, and the layout direction of the sliding groove is perpendicular to the side wall of the rotating block 7; a slider 82 horizontally slidably arranged in the track plate 81, and the size of the slider 82 matches the size of the sliding groove on the track plate 81; a spring 83 arranged between the side wall of the rotating block 7 and the slider 82, a T-shaped push rod 84 arranged at the end of the slider 82 away from the spring 83, and an arc plate 85 arranged at the end of the T-shaped push rod 84 away from the slider 82 and located at the outer edge of the chassis 6, and the central axes of all the arc plates 85 on the same rotating block 7 coincide with each other; wherein, The arc plate 85 includes an arc segment 851 and a conical segment 852 which are arranged in sequence from top to bottom and whose central axes overlap each other. The small diameter end of the conical segment 852 is located along the side away from the arc segment 851; the connecting rod 841 of the T-shaped push rod 84 extends into the track plate 81 and is connected to the slider 82. The length of the push rod 842 of the T-shaped push rod 84 is greater than the width of the track plate 81. Such an arrangement can limit the position of the T-shaped push rod 84. When the outer wall of the arc segment 851 contacts the inner wall of the through hole on the placement slot plate 2, the connecting rod 841 pushes the slider 82 to compress the spring 83. At this time, the side of the push rod 842 contacts the side of the track plate 81 away from the rotating block 7. In this embodiment, the chassis 6 corresponds to the connection position of the arc segment 851 and the conical segment 852. When the top outer wall of the arc plate 85 contacts the inner wall of the through hole on the placement slot plate 2, the T-shaped push rod 84 pushes the slider 82 to compress the spring 83, and the inner wall of the arc plate 85 contacts the outer edge of the corresponding chassis 6, and the side edges of adjacent arc plates 85 contact each other.

[0040] During use, when it is necessary to take out the pear seedlings, the electric telescopic rod 3 is started, and the telescopic end of the electric telescopic rod 3 will push the push plate 4 to move upward, thereby driving the vertical rod 5, the chassis 6, the rotating block 7 and the retracting and unfolding mechanism 8 to move upward as a whole. When the conical surface section 852 below the arc plate 85 does not contact the inner wall of the through hole on the placement slot plate 2, the slider 82 is driven to slide along the track plate 81 under the elastic force of the spring 83, and the slider 82 slides in the direction away from the rotating block 7. The slider 82 pushes the T-shaped push rod 84 to drive the arc plate 85 to move outward, thereby moving the arc plate 85 away from the chassis 6. At this time, the retracting and unfolding mechanism 8 is unfolded, and the arc plate 85 will gradually separate from the soil of the pear seedlings when it is away from the chassis 6, thereby helping to maintain the integrity of the soil and the pear seedlings and avoiding excessive soil falling during the removal process. When it is necessary to use the chassis 6 and the curved plate 85 for breeding pear seedlings, the electric telescopic rod 3 is contracted and driven to reset the push plate 4. At this time, the push plate 4 drives the vertical rod 5, the chassis 6, the rotating block 7 and the retracting and unfolding mechanism 8 to move downward, and the T-shaped push rod 84 pushes the slider 82 to compress the spring 83. When the outer wall of the arc segment 851 on the curved plate 85 contacts the inner wall of the through hole on the placement slot plate 2, the inner wall of the curved plate 85 contacts the outer edge of the chassis 6. The curved plate 85 and the corresponding chassis 6 can be enclosed to form a seedling cavity for seedling cultivation, and seedlings are cultivated in the seedling cavity.

[0041] A fixing plate 11 is arranged between the inner walls on both sides of the box body 1. The fixing plate 11 is located between the placement slot plate 2 and the push plate 4, and the fixing plate 11 is parallel to the placement slot plate 2. The top of the rotating block 7 is rotatably matched with the bottom of the chassis 6. Specifically, an annular groove is opened at the bottom of the chassis 6, and a rotating rod matching the annular groove at the bottom of the chassis 6 is arranged on the top of the rotating block 7, thereby realizing its rotation; a spiral hollow rod 86 is sleeved on the outer wall of the vertical rod 5, and the inner diameter of the spiral hollow rod 86 is slightly larger than the outer diameter of the vertical rod 5. One end of the spiral hollow rod 86 is connected to the bottom of the rotating block 7, and the other end of the spiral hollow rod 86 passes through the fixing plate 11 and contacts with the top of the push plate 4, and the spiral hollow rod 86 is threadedly connected to the fixing plate 11.

[0042] When the push plate 4 pushes the vertical rod 5 to move upward, the push plate 4 will simultaneously push the spiral hollow rod 86 to move upward. The spiral hollow rod 86 is threadedly matched with the fixing plate 11, so the spiral hollow rod 86 will rotate when moving upward, thereby driving the rotating block 7 to rotate. When the rotating block 7 rotates, it will drive the retracting and unfolding mechanism 8 to rotate, so that the four arc plates 85 on the same rotating block 7 rotate and unfold. The rotation of the arc plate 85 can prevent excessive adhesion of soil to the inner wall of the arc plate 85, thereby further avoiding damage to the rhizomes of the pear seedlings.

The bottom of the nozzle 94 is provided with a plurality of water spraying ports 95 corresponding to the chassis 6. In this embodiment, the water spraying ports 95 are composed of a plurality of water outlet holes, and are distributed to form a circular structure.

Start the motor 97, and the output shaft of the motor 97 will drive the connecting column 99 to rotate. The rotation of the connecting column 99 will cause the T-shaped block 98 to move back and forth along the reciprocating track groove 991 of the connecting column 99, and then drive the baffle 910 to reciprocate at the bottom of the nozzle 94 through the T-shaped block 98. The top of the baffle 910 contacts the bottom of the nozzle 94. The reciprocating movement of the baffle 910 will cause the water in the nozzle 94 to be sprayed out in a quantitative manner, thereby preventing excessive watering from causing waterlogging in the soil or root rot of the pear seedlings.

[0046] A fixed pipe 911 is provided at the bottom of the baffle 910, a hose 912 is connected between the fixed pipe 911 and the nozzle 94, and a nozzle 913 corresponding to the chassis 6 is provided at the bottom of the fixed pipe 911.
