Description

Technical Field

[0001] The invention relates to the technical field of fertilization, and in particular to a fixed-point fertilization device suitable for landscape gardening maintenance. Background Art

[0002] At present, when planting plants in landscape gardens, it is necessary to dig holes and apply fertilizers, which are mostly done manually. This operation method is labor-intensive for the workers on the one hand, and low work efficiency on the other hand. In addition, there may be differences in the amount of fertilizer applied, resulting in large differences in the growth rate of the plants, which is inconvenient to manage.

[0003] To solve the above problems, a Chinese patent with publication number CN211721052U discloses a garden pit digging and fertilizing device, including a base plate and a fertilizer placement chamber, both sides of one end of the top of the base plate are fixedly provided with vertical plates, the two ends of the bottom of the fertilizer placement chamber are respectively fixedly connected to the tops of the two vertical plates, a feed pipe is fixedly plugged into a corner of the top of the fertilizer placement chamber, a handrail is provided at the bottom of the front of the fertilizer placement chamber, an electric slide is fixedly provided at the top of the inner cavity of the fertilizer placement chamber, and a rake is fixedly provided at the bottom of the slider of the electric slide; the patent uses mechanical equipment instead of manual labor to dig pits and apply fertilizers, which reduces the labor intensity of the staff and improves work efficiency; and it can also ensure that the amount of fertilizer in each pit is the same, thereby ensuring that the growth rate of each plant will not differ too much, which is convenient for management.

[0004] The above patent has the following problems during actual use: during the digging process, the entire device will generate large vibrations, causing the entire device to be displaced under the drive of the rolling wheels, resulting in the size of the pit to become larger. When planting plants, it takes longer to backfill the soil, which increases the workload and makes the operation more complicated. In addition, during the digging process, the previous pit will also be fertilized. If the entire device is displaced, it will directly lead to the displacement of the fertilization position, that is, the designated pit cannot be fertilized. Therefore, manual search and supplementary fertilization are required, which increases the workload and makes the operation more complicated. Summary of the invention

[0005] The present invention aims to provide a fixed-point fertilization device suitable for landscape gardening maintenance, so as to solve the problem that the existing pit digging fertilization device may cause the entire device to deviate due to vibration during pit digging.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a fixed-point fertilization device suitable for landscape garden maintenance, comprising a box body and a drilling mechanism, the box body is provided with a feed port and a discharge port, a material box is provided in the box body, and the material box is communicated with the feed port; bottom blocks are provided on both sides of the bottom of the box body, and a traveling wheel is rotatably connected to the bottom block; a screw is rotatably connected in the box body, a lifting block is threadedly connected to the screw, and the drilling mechanism is arranged on the lifting block; a vertical groove is provided in the box body, and the lifting block is slidably connected to the vertical groove; a through hole and a bottom hole are provided at the bottom of the box body, and the lifting block and the drilling mechanism can both move vertically in the through hole, a movable block is slidably connected in the bottom hole, the movable block is fixedly connected to the lifting block, and a plurality of positioning rods are provided at the bottom of the movable block;

[0007] The utility model also comprises a driving mechanism for driving the screw rod to rotate, and a leading mechanism for leading the fertilizer in the material box out of the material outlet through the material outlet as the movable block moves vertically.

[0008] The principles and advantages of this solution are:

[0009] 1. In this solution, the lifting block drives the drilling mechanism to pass through the through hole and act on the ground to dig a hole in the ground. Compared with the prior art, during the downward movement of the lifting block, the lifting block drives the movable block to move downward as well, so that the movable block drives the positioning rod to be inserted into the ground before the drilling mechanism, that is, the positioning rod can be used to position the entire device, thereby avoiding the displacement of the entire device due to vibration during digging, ensuring the accuracy of the digging position, and ensuring the fixed size of the pit, so that the pit can be backfilled with soil in the same time, and the operation is simpler.

[0010] 2. During the downward movement of the lifting block of this scheme, it can drive the drilling mechanism to dig a hole in the land. At the same time, the fertilizer in the material box can be led out from the discharge port through the lead-out mechanism and act on the previous pit, thereby realizing fertilization. That is, this scheme can fertilize the previous pit while digging a hole, which is highly practical.

[0011] 3. During the pit digging process, this solution can accurately apply fertilizer to the pit by positioning the entire device, avoiding the displacement of the fertilization position, and eliminating the need for manual search and supplementary fertilizer, thus reducing the workload and making the operation easier.

[0012] Furthermore, a bottom groove is provided at the bottom of the bottom block, and the traveling wheel is located in the bottom groove and can rotate in the bottom groove; a support block is connected in the bottom groove, baffles are provided on both sides of the support block, and the traveling wheel is located between the two baffles.

[0013] Through the above arrangement, the two baffles can shield the traveling wheels, thereby protecting the traveling wheels and extending the service life of the traveling wheels.

[0014] Furthermore, a first inclined groove and a rack are provided in the bottom groove, and the spacing between the two first inclined grooves gradually decreases from top to bottom. A first auxiliary block is slidably connected in the first inclined groove, and the first auxiliary block is fixedly connected to the support block; the rack is inclined, and the inclination direction of the rack is parallel to the inclination direction of the first inclined groove. The traveling wheel is located on a movement trajectory of a baffle on the support block, and a circular shaft is rotatably connected to another baffle on the support block, and a gear is coaxially connected to the circular shaft, and the gear is meshed with the rack; a clamping plate is provided on the circular shaft, and the traveling wheel is located on the movement trajectory of the clamping plate; and it also includes a linkage mechanism that drives the first auxiliary block to move along the path of the first inclined groove as the movable block moves vertically.

[0015] Through the above arrangement, during the downward movement of the movable block, the first auxiliary block drives the supporting block to move obliquely upward along the path of the first inclined groove, so that the supporting block simultaneously drives the two baffles to move obliquely upward, so that the baffle close to the movable block abuts against the traveling wheel, and the baffle away from the movable block is away from the traveling wheel; during the movement of the baffle away from the movable block, the gears move synchronously, the engagement of the gears and the rack drives the circular shaft to rotate, and the circular shaft drives the clamping plate to rotate and abut against the traveling wheel, that is, the baffle close to the movable block and the clamping plate traveling wheel are used to clamp the driving wheel, thereby playing a positioning role for the entire device, further strengthening the positioning effect of the entire device, and avoiding displacement of the entire device due to vibration.

[0016] Furthermore, the linkage mechanism includes a fixed plate fixed to the bottom of the box body, side grooves and wall grooves provided on the movable block, second inclined grooves are provided on both sides of the side walls of the fixed plate, and the spacing between the two second inclined grooves gradually increases from top to bottom; a second auxiliary block is slidably connected in the second inclined groove, and one end of the second auxiliary block away from the second inclined groove is slidably connected to the side groove; the wall groove is communicated with the side groove, and a wall block is slidably connected in the wall groove, and one end of the second auxiliary block away from the second inclined groove is fixed to the wall block; the wall block passes through the bottom groove, and the wall block can move horizontally and vertically in the bottom groove; a sliding groove is vertically provided on the wall block, and a sliding block is slidably connected in the sliding groove, and the sliding block is fixed to the support block.

[0017] Through the above arrangement, during the downward movement of the movable block, the movable block drives the second auxiliary block and the wall block to move downward synchronously, so that the second auxiliary block drives the wall block to move laterally along the path of the second inclined groove in a direction away from the wall groove, that is, the two wall blocks move away from each other; during the lateral movement of the wall block, the wall block drives the slider to move synchronously, so that the first auxiliary block drives the slider to move upward along the path of the first inclined groove through the first auxiliary block and the support block.

[0018] Furthermore, an elastic layer for abutting against the traveling wheel is provided on the abutting plate.

[0019] Through the above arrangement, the elastic layer abuts against the traveling wheel and deforms, so that the elastic layer and the traveling wheel are in contact at more positions, thereby increasing the contact surface between the two, increasing the friction between the two, and improving the stability of the traveling wheel positioning.

[0020] Furthermore, the lead-out mechanism includes a guide platform fixedly connected to the box body and a wedge block fixedly connected to the movable block. The guide platform is vertically provided with a guide hole, which is communicated with the material box and the discharge port; a transverse groove is provided on the guide platform, which is communicated with the guide hole, a transverse block is slidably connected in the transverse groove, and a spring is provided between the transverse block and the guide platform; a drainage hole for communicating with the guide hole is vertically provided on the transverse block, and the drainage hole and the guide hole are staggered; a wedge surface is provided on the transverse block, and the wedge surface is located on the movement trajectory of the wedge block.

[0021] Through the above arrangement, during the downward movement of the movable block, the movable block drives the wedge block to move synchronously, so that the wedge block squeezes the wedge surface to drive the transverse block to move leftward in the transverse groove, and the spring is compressed to connect the drainage hole with the guide hole, so that the material falls into the previous pit through the guide hole, drainage hole and discharge port, thereby realizing fertilization treatment.

[0022] Furthermore, an inner groove is transversely provided on the inner wall of the material box, a push plate is slidably connected in the inner groove, and the push plate is in frictional contact with the bottom of the material box; and a power mechanism is also included to drive the push plate to move transversely as the screw rotates.

[0023] Through the above arrangement, the push plate moves laterally along the path of the inner groove, thereby reducing the storage space in the material box, thereby promoting the fertilizer in the material box to be completely moved out of the guide hole, that is, improving the utilization rate of the fertilizer.

[0024] Furthermore, the power mechanism includes a driving bevel gear fixedly connected to the screw rod, a transverse shaft rotatably connected to the material box, and a driven bevel gear meshing with the driving bevel gear is coaxially connected to the transverse shaft.

[0025] Through the above arrangement, during the rotation of the screw, the screw will also drive the active bevel gear to rotate, and the active bevel gear meshes with the driven bevel gear to drive the transverse shaft to rotate, so that the push plate moves laterally along the path of the inner groove.

[0026] Furthermore, the bottom of the positioning rod is conical; and a plurality of protrusions are provided on both sides of the positioning rod.

[0027] Through the above arrangement, the bottom of the positioning rod is conical and can be inserted into the ground more conveniently; the protrusion on the positioning rod can increase the contact area with the ground, thereby enhancing the positioning effect of the entire device.
