Description

TECHNICAL FIELD

[0001] The utility model relates to a planting and mulching technology field, and specifically relates to a melon planting mulching device. BACKGROUND

[0002] Melon is an annual vine herb, the stem and branch have edges, the leaf blade is thick paper quality, and is round or kidney-shaped. The flower is unisexual and hermaphrodite, the male flower is yellow, the ovary of the female flower is densely covered with soft hair, the fruit shape is various, and common spherical or long elliptical, melon planting needs to select the loose soil with sufficient illumination and good drainage, needs to soak the seed and germinate before sowing to improve the germination rate, can directly sow or transplant seedling when the spring temperature is stable above 15 DEG C, needs to keep the soil wet but avoids the accumulated water during the growth period, and timely erects the frame or arranges the vine to promote ventilation and light transmission.

[0003] The existing mulching device lacks resistance limitation for the rotation of the roller shaft in actual use, so that the mulching material is difficult to rotate synchronously with the equipment movement due to inertia effect during the laying process, and then the actual rotation speed exceeds the laying speed of the equipment movement, which causes the mulching material to accumulate or stretch and deform, and directly affects the mulching flatness. In view of this, the melon planting mulching device is provided. UTILITY MODEL CONTENTS

[0004] The utility model aims at making up for the deficiency of prior art, and provides a melon planting mulching device.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a melon planting mulching device, including the welding frame, one side of the welding frame top surface is fixedly connected with the handle, and the both sides of the welding frame outer wall are rotatably connected with a plurality of wheel groups, the both sides of the welding frame inner wall are fixedly connected with a plurality of bending frames, and the plurality of bending frames are fixedly connected with the central shaft, the both ends of the central shaft outer wall are rotatably connected with a plurality of rotating rollers through the bearing, and the corresponding end of the rotating roller is fixedly connected with a plurality of fixed rods, the central part of the central shaft is connected with a plurality of sliding rods, and the bottom end of the sliding rod is fixedly connected with the limiting ring, the top surface of the sliding rod is fixedly connected with the friction plate, the top of the sliding rod outer wall is sleeved with the compression spring, the bottom surface of the friction plate is fixedly connected with the bolt, and the central part of the central shaft is rotatably connected with the threaded sleeve.

[0006] The top surface of the friction plate is tightly attached to the top end of the inner wall of the rotating roller, and the friction plate is mainly pressed from metal powder high-temperature sintering.

[0007] The bottom of the sliding rod outer wall is tightly attached to the inner wall of the central shaft, and the bottom of the sliding rod outer wall is slidably connected with the inner wall of the central shaft.

[0008] The center shaft inner wall is fixedly connected with a plurality of intercepting rings, and the intercepting ring bottom surface corresponds to the limiting ring top surface.

[0009] The compression spring top end outer wall is in abutment with one side of the friction plate bottom surface, and the compression spring bottom end outer wall is in abutment with the intercepting ring top surface.

[0010] The bolt outer wall bottom extends to the center shaft inner center, and the bolt is located at the threaded sleeve top center.

[0011] The bolt outer wall thread is in engagement with the threaded sleeve inner wall thread.

[0012] Compared with the prior art, the melon planting film covering device has the following beneficial effects:

[0013] First, the film roll is sleeved on the outer wall of the rotating roller, and the elastic pressure generated by the compression spring makes the friction plate continuously adhere to the inner wall of the rotating roller, forming a frictional resistance. When the equipment moves, the frictional resistance formed by the contact surface between the rotating roller and the friction plate will force the rotating speed of the film roll to be synchronized with the moving speed of the equipment. If the film roll rotates ahead, the sliding friction between the friction plate and the rotating roller will quickly reduce the rotating speed of the rotating roller, thereby avoiding the accumulation or excessive stretching of the material. When the equipment stops moving, the continuous pressing action of the friction plate can immediately eliminate the inertial rotation of the rotating roller, preventing the material from relaxing and sagging.

[0014] Second, the friction plate can be pressed downward, and after the bolt outer wall contacts the threaded sleeve inner wall, the threaded sleeve is rotated to lock the friction plate, so that the friction plate loses the frictional resistance limitation when rotating on the inner wall of the rotating roller. After locking, the friction plate is completely separated from the inner wall of the rotating roller, and the rotating roller can freely rotate without resistance limitation, so as to facilitate the maintenance of the equipment by the operator.

[0015] Other advantages, objects and features of the present application will be set forth in part in the following specification, and in part will become apparent to those skilled in the art upon examination of the following specification, or can be learned from practice of the present application, the specifics of which are set forth in the claims.

DETAILED DESCRIPTION

[0021] 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, not 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 protection of the utility model.

[0022] As Figures 1-4 shown, the utility model provides a kind of technical scheme: a melon planting film mulching device, including welding frame 1, welding frame 1 top side is fixedly connected with handle 101, and welding frame 1 outer wall both sides are rotatably connected with multiple wheel sets 102, welding frame 1 inner wall both sides are fixedly connected with multiple bending frames 2, and multiple bending frames 2 are fixedly connected with center shaft 201 between, and the both ends of center shaft 201 outer wall are rotatably connected with multiple rotating rollers 202 by bearing, and the corresponding end of rotating roller 202 is fixedly connected with multiple fixed rods 203, and multiple sliding rods 204 are connected in the inside center of center shaft 201, and the bottom end outer wall of multiple sliding rods 204 is fixedly connected with limiting ring 205, the top outer wall of sliding rod 204 is fixedly connected with friction plate 206, and the outer wall top of sliding rod 204 is equipped with compression spring 207, and the bottom surface center of friction plate 206 is fixedly connected with bolt 208, and threaded sleeve 209 is rotatably connected in the inside center of center shaft 201.

[0023] The elastic pressure generated by compression spring 207 makes friction plate 206 continuously close to rotating roller 202 inner wall, and forms friction resistance, when equipment travels, the friction resistance formed by the contact surface between rotating roller 202 and friction plate 206 will force film mulching roll rotating speed and equipment moving speed to tend to be synchronized.

[0024] As Figure 4 shown, the top surface both sides of friction plate 206 are tightly combined with the top end of the inner wall of multiple rotating rollers 202 respectively, and friction plate 206 is mainly pressed after being sintered by metal powder at high temperature.

[0025] The friction plate 206 is formed by a high-temperature sintering process to have a dense structure, and can maintain a stable friction coefficient when the rotating roller 202 rotates at a high speed, thereby avoiding resistance failure caused by material softening or wear.

[0026] As shown in Figure 4 , the outer wall of the sliding rod 204 is tightly attached to the inner wall of the central shaft 201, and the outer wall of the sliding rod 204 is slidingly connected to the inner wall of the central shaft 201.

[0027] By tightly attaching the outer wall of the sliding rod 204 to the inner wall of the central shaft 201, the central shaft 201 can constrain the sliding rod 204 in movement, avoiding it from deviating from the preset movement track.

[0028] As shown in Figure 4 , the inner wall of the central shaft 201 is fixedly connected with a plurality of intercepting rings 2010, and the bottom surface of the intercepting ring 2010 corresponds to the top surface of the limiting ring 205.

[0029] The intercepting ring 2010 can constrain the movement distance of the sliding rod 204, limiting the displacement distance of the sliding rod 204.

[0030] As shown in Figure 4 , the top end of the compression spring 207 is in contact with one side of the bottom surface of the friction plate 206, and the bottom end of the compression spring 207 is in contact with the top surface of the intercepting ring 2010.

[0031] By contacting the two ends of the compression spring 207 with the outer walls of the friction plate 206 and the intercepting ring 2010 respectively, the compression spring 207 can stably provide upward elastic force for the friction plate 206, ensuring that the friction plate 206 is tightly attached to the inner wall of the rotating roller 202 to generate appropriate friction resistance.

[0032] As shown in Figure 4 , the outer wall of the bolt 208 extends to the inner center of the central shaft 201, and the bolt 208 is located at the top center of the threaded sleeve 209.

[0033] When the friction plate 206 is pressed downward, the outer wall of the bolt 208 can be attached to the inner wall of the threaded sleeve 209.

[0034] As shown in Figure 4 , the outer wall of the bolt 208 is in threaded engagement with the inner wall of the threaded sleeve 209.

[0035] When it is necessary to lock the friction plate 206, it is only necessary to press the friction plate 206 downward and rotate the threaded sleeve 209, so as to move the bolt 208 up and down by means of threaded cooperation, and fix the position of the friction plate 206.

[0036] Working principle: the friction plate 206 is formed by high-temperature sintering process to form a dense structure, can maintain stable friction coefficient in the high-speed rotation of the rotating roller 202, avoid the resistance failure caused by material softening or wear, the outer wall of the sliding rod 204 and the inner wall of the center shaft 201 are tightly fitted, so that the center shaft 201 can constrain the sliding rod 204 in movement, avoid its departure from the preset moving track, the intercept ring 2010 can constrain the moving distance of the sliding rod 204, limit the displacement distance of the sliding rod 204, the both ends of the compression spring 207 are respectively in contact with the outer wall of the friction plate 206 and the intercept ring 2010, so that the compression spring 207 can stably provide upward elastic force for the friction plate 206, ensure that the friction plate 206 is tightly fitted with the inner wall of the rotating roller 202, so as to generate appropriate friction resistance, ensure that the outer wall of the bolt 208 is fitted with the inner wall of the threaded sleeve 209 when pressing the friction plate 206 downward, when it is needed to lock the friction plate 206, only need to press the friction plate 206 downward and rotate the threaded sleeve 209, can drive the bolt 208 to move up and down by means of threaded cooperation, and fix the position of the friction plate 206.
