A kind of crop-pulling, gathering and profiling cutting device

Abstract

The present invention is mainly used in the field of agricultural and forestry machinery, and in particular, it relates to a gathering, profiling, cutting and harvesting device for sand-growing bushes. The purpose of the present invention is to provide a straw-pulling, gathering and profiling cutting device, which aims to solve the problem of poor profiling cutting ability in the current bush stubble operation. When cutting the bushes, first use the hanging support component and the lifting mechanism to adjust the clamping mechanism to complete the gathering of the bushes, and then drive the cutting device through the power telescopic device to complete the cutting and profiling action. The entire cutting and profiling action is divided into two steps: 1. First, use a flat cutting tool to cut the roots of the bushes flat; 2. Then use a three-dimensional profiling cutting tool to profile and prune the roots. It can perform good cutting and profiling on the sand bags formed at the roots of the bushes due to the accumulation of sand, gravel and wind-blown sand, thereby ensuring the consistency of the stubble height.

Description

Technical Field

[0001] The invention is mainly applied to the field of agricultural and forestry machinery, and in particular relates to a gathering and profiling cutting and harvesting device for sand-growing shrubs. Background Art

[0002] Desert shrubs are mostly planted in arid and semi-arid areas. They have strong ecological adaptability, developed root systems, and strong water absorption. They play a vital role in preventing wind and sand, conserving water and soil, and improving soil structure in Northwest my country. According to the biological characteristics and agronomic requirements of desert shrubs, they must be cut every 3 to 5 years, otherwise their growth rate will slow down or even die naturally.

[0003] As the growth areas of sandy shrubs are covered with sand and stones and the spacing between plants is uneven, under the influence of wind, sand and gravel all year round, sand bags are raised at the roots of the Caragana korshinskii clusters, the surrounding ground is uneven, and the bearing capacity of the sand surface is low. Currently, most of the existing towed or self-propelled Caragana korshinskii harvesters have problems such as single function of the implements and poor equipment drive, poor contour cutting ability, and low cutting quality, which has become a prominent problem restricting the development of the Caragana korshinskii planting industry.

[0004] Therefore, in view of the terrain conditions of sandy shrubs and the requirements of stubble operations, the present invention has designed a contour stubble cutting table device that is adaptive to the terrain of shallow hills and mountains and can effectively cut and profile the sand bags formed at the roots of the shrubs due to the accumulation of sand, gravel and wind-blown sand, thereby ensuring consistent stubble height and smooth incisions. Summary of the invention

[0005] The present invention aims to provide a straw-pulling and gathering profiling cutting device, which aims to solve the problems of poor profiling cutting ability and low cutting quality in the current shrub stubble operation, provide good cutting conditions for stubble of shrubs on complex ground, and improve the cutting quality of shrubs.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] 1. A crop-pulling and gathering profiling cutting device, characterized in that it consists of five parts: a mobile platform, an operating console, a suspension support component, a profiling cutting component, and a crop-pulling and gathering device; the mobile platform is a motor vehicle with a front suspension structure that can travel in the field; the suspension support component controls the cutting posture of the entire cutting device through a vehicle-mounted drive device; the profiling cutting component includes two parts, a power telescopic device and a cutting device, the power telescopic device drives the cutting device to make it move longitudinally relative to the cutting platform; the crop-pulling and gathering device can adjust its different swing angles through a drive device to complete the gathering of bushes with different ground diameters.

[0008] 2. According to the above-mentioned crop-pulling and gathering profiling cutting device, the revolution and rotation of the profiling cutting tool of the profiling cutting component are respectively realized through the meshing transmission of gears, so as to achieve the purpose of profiling the sandbags at the roots of the bushes.

[0009] 3. According to the crop-pulling and gathering profiling cutting device, the cutting device of the profiling cutting component is driven by the power telescopic device, and the cutting is completed by the horizontal cutting tool and the profiling cutting tool.

[0010] 4. According to the described straw-pulling and gathering profiling cutting device, the lifting device of the straw-pulling and gathering component includes a driver, a rectangular tube, and a support frame. The support frame is hinged to the driver and the parallel four-bar mechanism respectively. By changing the stroke of the driver, the reciprocating swing angle of the parallel four-bar mechanism is adjusted.

[0011] 5. According to the crop-pulling and gathering contour cutting device, the clamping device of the crop-pulling and gathering component is fixed on the parallel four-bar mechanism connecting member, and the up and down lifting movement of the clamping device is realized through the reciprocating swing of the parallel four-bar mechanism.

[0012] 6. According to the straw-grabbing, gathering and profiling cutting device, the claws of the clamping device are hinged to the front and back sides of the connecting piece, respectively, leaving a certain gap in the middle; the connecting piece is fixedly connected to one end of the transverse driver, and the opening degree of the clamping device is changed by the extension and contraction of the transverse driver.

[0013] The benefit of the crop-pulling, gathering and profiling cutting device provided by the present invention is that the bushes are cut flat and profiled in steps to meet the cutting requirements of the profile cutting. The roots of the bushes are first cut flat by a plane cutting tool, and then pruned by a profile cutting tool, thereby ensuring the consistency of the flat height. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be emphasized that the following description is only intended to explain the present invention, and is not intended to limit the scope and application of the present invention.

[0026] The crop-pulling, gathering and profiling cutting device of the present invention has a specific implementation as follows Figures 1 to 7 As shown:

[0027] like Figure 1As shown, the overall equipment of the crop-pulling, gathering and profiling cutting device of the present invention is composed of a mobile platform 1, a hanging support component 2, a crop-pulling, gathering device 3, a profiling cutting component 4 and an operating table 5.

[0028] The mobile platform 1 of the crop-pulling, gathering and profiling cutting device is an agricultural wheeled tractor with a front suspension structure, and may also be other mobile platforms with a front suspension structure having the same function.

[0029] The function of the suspension support component 2 in the straw-grabbing, gathering and profiling cutting device is to adjust the relative posture of the entire device and the cutting target so that it reaches the best cutting position. The tractor front suspension lifting hydraulic cylinder 2a is hingedly connected to the mobile platform front suspension lifting bracket 2c through the lifting connecting pin 2b, and the clamping ring of the general support frame 43 is inserted into the clamping groove of the mobile platform front suspension lifting bracket 2c and locked; the two ends of the posture adjustment hydraulic cylinder 2e are respectively hinged to the general support frame 43 and the posture adjustment base 2f; the hydraulic cylinder 2e drives the general support frame 43 to perform lateral reciprocating swinging motion with the clamping groove of the mobile platform front suspension lifting bracket 2c as the center.

[0030] like Figure 3 As shown, the weed-grazing and gathering device is divided into two parts: a lifting mechanism 3a and a clamping mechanism 3b. The lifting mechanism 3a is composed of a lifting driver 3aa, a support rod 3ab, a rectangular tube 3ac, and a parallel four-bar mechanism connecting rod 3ad. The openings at both ends of the rectangular tube 3ac are hinged to the main support frame 43 and the parallel four-bar mechanism connecting rod 3ad. The support rod 3ab is fixedly connected to the rectangular tube 3ac. The two ends of the lifting driver 3aa are respectively hinged to the main support frame 43 and the support rod 3ab. The clamping position of the clamping mechanism 3b is indirectly adjusted by controlling the telescopic displacement of the lifting driver 3aa. The clamping mechanism 3b is composed of a clamping claw 3ba, a connecting rod 3bb, an electric push rod 3bc, and a connecting support rod 3bd. The housing of the electric push rod 3bc is fixedly connected to the parallel four-bar mechanism connecting rod 3ad, and the push rod of the electric push rod 3bc is fixedly connected to the connecting support rod 3bd. The clamping claw 3ba is respectively hinged to the positive and negative sides of the connecting support rod 3bd. The gripping claw 3ba and the parallelogram connecting rod 3ad are connected via a connecting rod 3bb; the opening degree of the gripping claw 3ba is adjusted by the push range of the electric push rod 3bc.

[0031] The contour cutting component 4 is divided into three parts: a power telescopic device 41, a cutting device 42 and a main support frame 43. Figure 6As shown, the power telescopic device 41 is composed of a plurality of telescopic rods 41e and a telescopic rod connecting pin 41f, and the sides are respectively hinged to the cutting device bracket 42b and the main support frame 3d through the base fixed connecting pin 41c; the two ends of the telescopic driver 41a are respectively hinged to the telescopic device base 43b and the power connection sliding pin 41b, and the power connection sliding pin 41b slides in the bracket moving guide groove 43c, and controls the telescopic movement of the power telescopic device 41 by driving the telescopic driver 41a. After the displacement connection sliding pin 41d is riveted to the power telescopic device 41, it slides in the moving slide groove of the cutting device bracket 42b, thereby providing a lateral movement driving force to the cutting device 42. When the cutting device 42 is in the working state, the power telescopic device 41 is extended to provide a longitudinal driving force to the cutting device 42. When the cutting device 42 is in the non-working state, the power telescopic device 41 is retracted to make the guide wheel 42c fall on the wheel support frame 43a.

[0032] like Figure 7 As shown, the cutting device 42 is connected to the main support frame 43 through the power telescopic device 41. The splitter 42g and the profiling power input hydraulic motor 42d are fixedly connected to the cutting device bracket 42b. The splitter 42g transmits power to the cutting rotating shaft 42f and the profiling rotation power input gear 42ah through the cutting power input flexible shaft 42h and the profiling power input flexible shaft 42i, respectively providing cutting power to the cutting saw blade 42e and the profiling cutting tool 42ab. The cutting saw blade 42e is fixed to one end of the cutting rotating shaft 42f, and the cutting saw blade 42e is driven to rotate and cut by the rotation of the cutting rotating shaft 42f. The profiling power input hydraulic motor 42d provides rotational power to the profiling support rotating shaft 42ae through the profiling revolution rotation power input flexible shaft 42j.

[0033] Gearbox system such as Figure 8 As shown, the two ends of the profiling cutting rotating shaft 42ac are respectively fixedly connected to the profiling cutting tool 42ab and the bevel gear 42ad, and are supported by the profiling supporting rotating shaft 42ae; the rotation speed of the profiling supporting rotating shaft 42ae controls the revolution speed of the profiling cutting tool 42ab; the bevel gear shaft 42aa and the bevel gear 42ad are meshed and driven to control the rotation speed of the profiling cutting tool 42ab.

[0034] The rotational power transmission route of the profiling cutting tool 42ab is: the shaft splitter 42g→the profiling rotational power input flexible shaft 42i→the rotational power input gear 42ah→the bevel gear shaft 42aa→the bevel gear 42ad→the profiling connecting shaft 42ac→the rotation of the profiling cutting tool 42ab.

[0035] The revolution power transmission route of the profiling cutting tool 42ab is: the profiling power input hydraulic motor 42d→the profiling revolution rotation power input flexible shaft 42j→the revolution power input gear 42af→the profiling support rotation shaft 42ae→the profiling cutting tool 42ab revolves.

[0036] The following is an explanation based on the specific operation situation. The entire stubble cutting process is divided into two steps:

[0037] Step 1: If Fig. 9 As shown, after the root of the bushes is clamped, gathered and lifted by the weed-pulling and gathering device 3, the power telescopic device 41 is extended to drive the cutting saw blade 42e to move forward for parallel cutting;

[0038] Step 2: After the cutting saw blade 42e completes parallel cutting of the bushes, as the power telescopic device 41 is further extended and driven, the contour cutting knife 42ab is driven to approach the sandbag. When the highest point of the sandbag is reached, the power telescopic device 41 stops driving, and the contour cutting is completed by the cutting saw blade 42e. The bush trimming operation is repeated in this way.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
